An open textbook is like a commercial textbook, except: (1) it is publicly available online free of charge

(and at low-cost in print), and (2) it has an open license that allows others to reuse it, download and

revise it, and redistribute it. This book has a Creative Commons Attribution license, which allows

reuse, revision, and redistribution so long as the original creator is attributed (please see the licensing

information for this book for more information).

In addition to saving students money, an open textbook can be revised to be better contextualized

to one’s own teaching. In a recent study of undergraduate students in an introductory level physics

course, students reported that the thing they most appreciated about the open textbook used in that

course was that it was customized to fit the course, followed very closely by the fact that it was free

of cost (Hendricks, Reinsberg, and Rieger 2017). For example, in an open textbook one may add in

examples more relevant to one’s own context or the topic of a course, or embedded slides, videos, or

other resources. Note from the licensing information for this book that one must clarify in such cases

that the book is an adaptation.

A number of commercial publishers offer relatively inexpensive digital textbooks (whether on their

own or available through an access code that students must pay to purchase), but these may have

certain limitations and other issues:

• Access for students is often limited to a short period of time;

• Students cannot buy used copies from others, nor sell their own copies to others, to save

money;

• Depending on the platform, there may be limits to how students can interact with and take

notes on the books (and they may not be able to export their notes outside the book, so lose

access to those as well when they lose access to the book).

None of these is the case with open textbooks like the Introduction to Philosophy series. Students can

download any book in this series and keep it for as long as they wish. They can interact with it in

multiple formats: on the web; as editable word processing formats; offline as PDF, EPUB; as a physical

print book, and more.

We hope the books (or chapters in the books) will be adopted for introductory-level courses in

philosophy, as part of required readings. You may use the books as they are, or create adaptations or

ancillaries. One of the important benefits of the Introduction to Philosophy series is that instructors can

mix and match chapters from various books to make their own customized set of readings for their

courses.

Be sure to read the licensing information carefully and attribute the chapters or book properly when

reusing, redistributing, or adapting.

Each book can be read online, and is also downloadable in multiple formats, from their respective

book home pages (e.g., Introduction to Philosophy: Ethics).

• The .odt format can be opened by Open Office, Libre Office, or Microsoft Word. Note that

there may be some issues with formatting on this format, and hyperlinks may not appear if

opened with MS Word.

• The PDF files can be edited with Adobe Acrobat (the full program, not just the Reader) or

printed out. The print version of the PDF does not have hyperlinks.

• The EPUB and MOBI files can be loaded onto digital reading platforms like Adobe Digital

Editions, Apple Books, and Kindle. They can also be edited using Pressbooks or tools like

Calibre.

• Edits can be made using the XHTML format or via the Pressbooks XML format (for easier

adaptation in Pressbooks).

• The book is also available for download as a Common Cartridge 1.1 file (with web links) for

import into your learning management system (see instructions for importing Common

Cartridge files, from the Pressbooks User Guide).

The multiple editable formats allow instructors to adapt the books as needed to fit their contexts.

Another way to create adaptations is to involve students in contributing to open textbooks. Students

may add new sections to an adapted book, link to other resources, create discussion questions or

ETHICS ix

quiz questions, and more. Please see Rebus Community’s A Guide to Making Open Textbooks with

Students for more information and ideas.

If you plan to use or adapt one or more books (or chapters), we’d love to hear about it! Please let us

know on the Rebus Community platform, and also on our adoption form.

And if you have feedback or suggestions about the book, we would really appreciate those as well. We

have a separate form for keeping track of issues with digital accessibility, so please let us know if you

find any.

I N T RO D U C T I O N TO T H E S E R I E S

C H R I S T I N A H E N D R I C K S

This book is part of the Introduction to Philosophy open textbook series, a set of nine (and counting?)

open access textbooks that are designed to be used for introductory-level, survey courses in

philosophy at the post-secondary level.

OV E R V I E W O F T H E S E R I E S

This set of books is meant to provide an introduction to some of the major topic areas often covered

in introductory-level philosophy courses. I have found in teaching students new to philosophy that

many struggle with the new ideas, questions, and approaches they find in introductory courses in

philosophy, and that it can be helpful to provide them with texts that explain these in relatively

straightforward terms.

When I began this project there were few textbooks that I was happy enough with to ask students to

purchase, and even fewer openly licensed textbooks that I could pick and choose chapters from, or

revise, to suit my courses. This series was created out of a desire to provide such resources that can be

customized to fit different contexts and updated by instructors when needed (rather than waiting for

an updated version from a publisher).

Each book is designed to be accessible to students who have little to no background in philosophy, by

either eliminating jargon or providing a glossary for specialized philosophical terms. Many chapters

in the books provide examples that apply philosophical questions or concepts to concrete objects or

experiences that, we hope, many students are familiar with. Questions for reflection and discussion

accompany chapters in most of the books, to support students in understanding what to focus on as

they are reading.

The chapters in the books provide a broad overview of some of the main discussions and debates in

the philosophical literature within a topic area, from the perspective of the chapter authors. Some

of the chapters focus on historical approaches and debates, such as ancient theories of aesthetics,

substance dualism in Descartes, or classical utilitarian versus Kantian approaches in ethics. Others

introduce students to questions and topics in the philosophical literature from just the last few

decades.

ETHICS xi

The books currently in production for the series are:

• Aesthetics (Ed. Valery Vinogradovs and Scott Clifton): chapters include ancient aesthetics;

beauty in art and nature; the nature of art; art and emotions; art and morality; aesthetics and

politics

• Epistemology (Ed. Brian Barnett): chapters include epistemic justification; sources of

knowledge; skepticism; epistemic value, duty, and virtue; epistemology, probability, and

science; social epistemology; feminist epistemologies

• Ethics (Ed. George Matthews): chapters include ethical relativism; divine command theory and

natural law; ethical egoism and social contract theory; virtue ethics; utilitarianism; Kantian

Deontology; feminist ethics; evolutionary ethics

• Logic (Ed. Benjamin Martin): chapters include what is logic?; evaluating arguments; formal

logic; informal fallacies; necessary and sufficient conditions

• Metaphysics (Ed. Adriano Palma): chapters include universals; finitism, infinitism, monism,

dualism, pluralism; the possibility of free action; experimental metaphysics

• Philosophy of Mind (Ed. Heather Salazar): chapters include Descartes and substance dualism;

behaviourism and materialism; functionalism; qualia; freedom of the will

• Philosophy of Religion (Ed. Beau Branson): chapters include arguments for belief in God;

reasons not to believe; arguments against belief from the cognitive science of religion; from

philosophy of (mono)theism to philosophy of religions

• Philosophy of Science (Ed. Eran Asoulin): chapters include empiricism; Popper’s conjectures and

refutations; Kuhn’s normal and revolutionary science; the sociology of scientific knowledge;

feminism and the philosophy of science; the problem of induction; explanation

• Social and Political Philosophy (Eds. Sam Rocha and Douglas Giles): chapters include the ideal

society; the state of nature and the modern state; human rights, liberty, and social justice;

radical social theories

We envision the books as helping to orient students within the topic areas covered by the chapters, as

well as to introduce them to influential philosophical questions and approaches in an accessible way.

The books may be used for course readings on their own, or in conjunction with primary source texts

by the philosophers discussed in the chapters. We aim thereby to both save students money and to

provide a relatively easy route for instructors to customize and update the resources as needed. And

we hope that future adaptations will be shared back with the rest of the philosophical community!

Contributors to this series have been crowdsourced through email lists, social media, and other

means. Each of the books has its own editor, and multiple authors from different parts of the world

who have expertise in the topic of the book. This also means that there will inevitably be shifts in

voice and tone between chapters, as well as in perspectives. This itself exemplifies the practice of

philosophy, insofar as the philosophical questions worth discussing are those that do not yet have

xii SERIES INTRODUCTION

settled answers, and towards which there are multiple approaches worthy of consideration (which

must, of course, provide arguments to support their claim to such worth).

I have been thrilled with the significant interest these books have generated, such that so many people

have been willing to volunteer their time to contribute to them and ensure their quality—not only

through careful writing and editing, but also through extensive feedback and review. Each book in

the series has between five and ten authors, plus an editor and peer reviewers. It’s exciting to see so

many philosophers willing to contribute to a project devoted to helping students save money and

instructors customize their textbooks!

The book editors, each with expertise in the field of the book they have edited, have done the bulk of

the work for the books. They created outlines of chapters that were then peer reviewed and revised

accordingly, and they selected authors for each of the chapters. The book editors worked with authors

to develop a general approach to each chapter, and coordinated timelines for their completion.

Chapters were reviewed by the editors both before and after the books went out for peer review, and

the editors ensured revisions occurred where needed. They have also written introductions to their

books, and in some cases other chapters as well. As the subject experts for the books, they have had

the greatest influence on the content of each book.

My role as series editor started by envisioning the project as a whole and discussing what it might

look like with a significant number of philosophers who contributed to shaping it early on. Overall, I

have worked the Rebus Community on project management, such as developing author and reviewer

guidelines and other workflows, coordinating with the book editors to ensure common approaches

across the books, sending out calls for contributors to recruit new participants, and updating the

community on the status of the project through the Rebus Community platform. I have reviewed

the books, along with peer reviewers, from the perspective of both a philosopher who teaches

introductory-level courses and a reader who is not an expert in many of the fields the books cover.

As the books near publication, I have coordinated copy editing and importing into the Pressbooks

publishing platform (troubleshooting where needed along the way).

Finally, after publication of the books I and the book editors will be working on spreading the word

about them and encouraging adoption. I plan to use chapters from a few of the books in my own

Introduction to Philosophy courses, and hope to see many more adoptions to come.

This project has been multiple years in the making, and we hope the fruits of our many labours are

taken up in philosophy courses!

P R A I S E F O R T H E B O O K

B J Ö R N F R E T E R

This carefully edited anthology by George Matthews tackles many of the foundational questions of

Western philosophy while beautifully managing to make these philosophical inquiries truly accessible

to anyone who is willing to engage in them. All chapters are written to be understood; the

contributors show an honest and a caring attitude towards their audience.

The anthology is refreshing in its open-mindedness and its intelligible approach. This book will help

undergraduate students of philosophy—and those who teach undergraduates—to get comfortable

with the way Western ethicists ask and answer foundational ethical questions.

The book is written in a jargon-free, culturally sensitive, gender-appropriate, carefully deliberate

language. This is, in my opinion, of the highest importance. Students will thus be given a chance to

learn through these beautiful examples from an early stage in their own intellectual biography how to

address philosophical topics in a non-supremacist manner. They can adapt this attitude to their very

own philosophical work and become attentive in their thinking and their philosophical language to

those who were far too long ignored, rejected and dismissed in the history of Western philosophy.

The wide range of topics—from relativism to contract theory, from Natural Law Theory to feminist

ethics—are approached by asking exemplary questions and devising exemplary ethical situations. This

approach grounds the philosophical discourse in lived experience where it belongs. Philosophy is not

presented as an intellectual prestidigitation but as an existential exercise arising from being troubled

by these strangely incontrovertible questions of life.

I highly recommend this book as an introduction to those who wish to read an accessible yet rigorous

and challenging approach to Western ethics!

A project like this, with so many moving parts, is certainly a labor of love. I wish to thank all of the

many people involved in bringing this book to fruition. First and foremost I’d like to thank Christina

Hendricks for her tireless work orchestrating things as series editor and Apurva Ashok for her work

as Project Manager for the Rebus Community.

The authors of course are what make this book possible, and I’d like to thank them all. They are, in

the order of their chapters: Paul Rezkalla, Jeffrey Morgan, Douglas Giles, Ya-Yun (Sherry) Kao, Frank

Aragbonfoh Abumere, Joseph Kranak, Kathryn MacKay, and Michael Klenk. They have contributed

their expertise to this effort to better serve students of philosophy with an openly and freely accessible

textbook of the highest quality.

Finally I would like to thank the reviewers who patiently read through all of the chapters and

contributed their helpful comments, Björn Freter and Vance Ricks, as well as all of the many

contributors to the initial discussions that gave rise to this textbook on the forums of the Rebus

Foundation. We all hope you enjoy this book!

C H R I S T I N A H E N D R I C K S , S E R I E S E D I TO R

I would like to thank the authors in this book for their patience as we worked through the process of

conceiving the book and getting it to publication. Because this is one of the first books to be published

in the Introduction to Philosophy open textbook series, we were sometimes creating processes and

workflows as we went along, and this meant things may have taken longer than anyone expected at

first!

Special thanks to George Matthews, who was one of the first people to volunteer for this series as a

book editor, and has been incredibly flexible, patient, and dedicated to the work all the way through.

He has done an excellent job of selecting authors for chapters and helping them refine their work to

result in the clear and accessible finished book.

Also instrumental to the success of this book are the peer reviewers, Björn Freter and Vance Ricks,

ETHICS xv

who volunteered their time and expertise to read through a draft of the whole book and provide

constructive comments and suggestions.

Jonathan Lashley has done an amazing job with the design of the book covers for this series, using

original artwork by Heather Salazar (who is the editor for the Philosophy of Mind book in this series).

The book covers are exceptionally well done, and really bring the series together as a whole.

Colleen Cressman has provided much-needed help with copyediting. I am very grateful for her

thorough and detailed efforts, and for the suggestions she made to help make the chapters as

accessible as possible for introductory-level students. And thank you to Allison Brown for her help

with inputting and formatting the content into Pressbooks so that it looks and reads well.

When I started this project there were many discussions amongst philosophers from various parts

of the world on the Rebus Community platform, and their ideas and suggestions contributed

significantly to the final products. There were also numerous people who gave comments on draft

chapter outlines for each book. Thank you to the many unnamed philosophers who have contributed

to the book in these and other ways!

This book series would not have gotten beyond the idea stage were it not for the support of the Rebus

Community. I want to thank Hugh McGuire for believing in the project enough to support what we

both realized at the time was probably much bigger than even our apprehensions about its enormity.

Zoe Wake Hyde was instrumental in getting the project started, particularly in helping us develop

workflows and documentation. And I’m not sure I can ever thank Apurva Ashok enough for being an

unfailingly enthusiastic and patient supporter and guide for more months than I care to count. She

spent a good deal of time working with me and the book editors to figure out how to make a project

like this work on a day-to-day level, and taught me a great deal about the open publishing process.

Apurva kept me on track when I would sometimes drop the ball or get behind on this off-the-side-of-

my-desk project. She is one of the best collaborative partners I have never (yet!) met in person.

Finally, I want to thank my family for understanding how important this work is and why I have

chosen to stay up late so many nights to do it. And for their patience on the many groggy, pre-coffee

mornings that followed.

Is it ever acceptable to lie in order to protect someone from harm? Is selfless generosity really possible,

or are we humans always in one way or another motivated by selfish concerns? Should loyalty to

family, friends and one’s immediate community take precedence over one’s duty to obey the law? Such

questions, which belong to the rich and complex domain of moral reflection, are no doubt familiar

sorts of questions, even if there may seem to be no clear way of answering them with more than a

shrug of the shoulders and the assertion that “it all depends….”

Moral philosophy or ethics (I am here using these terms as broadly synonymous in spite of

distinctions between these terms that are sometimes made) is that branch of philosophy which

is concerned with the critical examination of these kinds of questions, along with the implicit

assumptions and theoretical commitments that lie behind them. Ethics is a branch of philosophical

value theory devoted to exploration of the broad rules which define, regulate and constrain our social

lives, as well as with the more abstract consideration of moral evaluation itself. Thus it also considers

such questions as whether there are general or even universal principles to which we may appeal in

our attempt to negotiate particular ethical dilemmas we may face. What might such principles look

like and why should we in fact follow them when they require us to set aside our impulses or interests?

Are universal principles even desirable as a goal in ethical deliberation and human development?

Clearly moral reflection and deliberation lie at the core of what it means to be human, members of

a species dependent upon each other and yet often unreliable and opportunistic at the same time.

Nevertheless moral thinking presents us with a deep puzzle. We are all intimately familiar with moral

thinking, while at the same time it may seem completely unclear how to approach it in anything

but a piecemeal fashion, reliant upon received ideas, customary approaches, and gut feelings. And

this is certainly not for a lack of attempts to get things right about the nature, origin, and basis of

judgments about right and wrong. These go back to at least the beginning of recorded history as is

evident in some of the earliest extant written artifacts, such as the stele of Hammurabi from ancient

Mesopotamia and the Buddhist King Ashoka’s inscriptions on pillars and boulders from the Gangetic

plain in ancient India. The following chapters take up this puzzle as their authors explore some of the

major theoretical approaches to moral philosophy under the conviction that we both can and should

subject moral reflection to critical analysis in search of the truth (or maybe the truths) about ethics.

ETHICS 1

As a way of setting the stage for the detailed accounts of various philosophical approaches to morality

and moral thinking in the following chapters, it may be helpful at the outset to distinguish between

three different ways in which we might approach moral thinking. We might first of all take an

approach similar to that of scientists interested in understanding and explaining some given set of

phenomena. We can call such an approach “descriptive ethics” since it is concerned with describing

and explaining the workings of moral deliberation as it actually takes place in the minds of real

people. Although this approach serves as the starting point for some contemporary approaches to

ethics (especially evolutionary and feminist approaches as discussed in the last two chapters), by and

large philosophers are less interested in describing and explaining moral thinking than they are in

the second of the two approaches, which more directly engages the evaluative side of the questions

with which we started. That is, philosophers, unlike scientists, are interested not only in clarifying

and explaining the workings of ethical thinking but also in examining the cases that can be made for

particular moral principles and approaches. This “normative” or “prescriptive” side of philosophical

ethics will be central to many of the chapters of this text, since they examine various philosophical

arguments as to why some particular approach to ethics should in fact be the one we accept as

opposed to its theoretical rivals. We may wonder, however, about the justification for this kind of

partisan approach to ethics in the first place. This brings us to the third way we might approach ethics,

by taking a step back from particular approaches to look at ethical thinking as such, as it relates to

other aspects of our intellectual and emotional lives. That is, we might ask more abstract theoretical

questions about the warrant for both rational ethical deliberation and prescriptive approaches to

ethics. This “meta-ethical” approach is important not only since it addresses the place of ethics in

our larger mental lives, but also as a way of addressing concerns that seem to get in the way of the

normative approaches we will be exploring.

The first chapter explores the metaethical claim that, in fact, there can be no real rational deliberation

about ethics, since ethical thinking is always bound by norms embedded within distinct human

cultures. Here Paul Rezkalla examines the case for and against different variations on the claim

that ethics is bound by norms of culture and place. In general relativism is found wanting in its

strongest version as a meta-ethical theory about the limits of rational approaches to ethics, although

it continues to be appealing in weaker versions for its defense of tolerance and cultural sensitivity as

fundamental ethical principles.

Next, Jeffrey Morgan considers the historical and currently popular claim that ethics is rooted in

religion. He does this by examining two particular approaches, that of Divine Command Theory,

which insists that without the authority of a purported divine author of moral commands, such

commands fail to bind human actors, and that of Natural Law Theory, which argues that a divinely

created natural order of things lies at the basis of all truths concerning right and wrong human actions

and decisions. Both of these approaches are found wanting, even if morality and religion remain

closely allied in their concern for human and social well-being.

The third chapter, written by Douglas Giles, directly considers the question of human well-being as

articulated by a family of approaches known as Virtue Ethics, as they have been developed in both

Western and non-Western philosophical contexts. Unlike other approaches which focus on the rules

and principles underlying ethical decision making, Virtue Ethics focuses on the actor him- or herself

2 INTRODUCTION TO THE BOOK

and the question of what it is that makes a person’s character good or bad in the conviction that ethical

action is always rooted in the particularities of an individual’s life and community.

In the fourth chapter, Sherry Ya-Yun Kao addresses a concern of secular rationalistic ethics, namely

that of understanding the relation between the self-interest of rational individuals out for their own

good and the basic rules of the social game proposed by ethics. First she considers the claims of

Egoism, in its two variants of Psychological Egoism, which denies the very possibility of any action

that is not selfish, and hence that ethics is impossible, and Ethical Egoism, which claims that ethical

restrictions on self-interest are counterproductive since the social good is in fact best achieved by the

private pursuit of personal gain. Having shown the weaknesses of these two approaches she moves on

to consider the advantages and disadvantages of Social Contract approaches to ethics, which attempt

to show that ethical rules and the interests of individuals bound by them can and must be in concord.

The fifth chapter, written by Frank Aragbonfoh Abumere explores the appeal of and drawbacks with

an approach closely allied to Social Contract Theory, which is known as Utilitarianism and which

remains one of the most influential approaches among contemporary philosophers. Utilitarianism is

an attempt to articulate and defend a genuinely universal ethics which is focused on the outcomes of

our actions and decisions as a measure of their moral worth.

Utilitarianism in turn is often contrasted with another attempt at a universal rationalistic ethics,

developed by the philosopher Immanuel Kant, as here described and critically analyzed by Joseph

Kranak in the sixth chapter. Kant’s ethics of duty, or deontological ethics, is based on the claim that

the moral worth of an act or principle is intrinsic to that act or principle itself and has little to do

with their consequences. This leads to a universalistic ethics based on an unconditional respect for

autonomous agents that has been enormously influential in the development of notions of human

rights, even though it remains controversial in moral philosophical and political contexts.

In the seventh chapter, Kathryn MacKay examines the influence of feminism on thinking about ethics

as she explores work at the intersection of developmental psychology, feminist social and political

theory, and philosophical accounts of moral thinking and deliberation. She explores the ongoing

debate about the nature and influence of sex and gender on both historical ethical theories and

contemporary attempts to address inequality and power in society at large.

Finally, this book ends with Michael Klenk’s account of the contributions of the science of biology,

especially evolutionary biology, to the development of a naturalistic ethics. Here he examines a variety

of claims concerning the possibility of understanding ethical norms as rooted in our nature as animals

always engaged in finding a balance between our competitive and cooperative tendencies. The debate

in this chapter, as in the last, is an ongoing interdisciplinary debate, although in this case it is among

contemporary philosophers, social theorists, and evolutionary biologists.

An Hindoo Woman throwing herself on the funeral pyre of her Husband by Frederic Shoberl. In The World in Miniature: Hindoostan via Wikimedia Commons. This work is in the public domain.

Her recently deceased husband lay on the funeral pyre waiting to be lit. Hundreds of people from the nearby

villages stood watching and waiting for the widow to carry out her duty of chastity to its culmination. As the pyre

was lit, the woman took several steps toward it and crawled on top of her husband’s corpse to embrace his neck.

ETHICS 7

The pain was excruciating, but if she dismounted then she would shame her family and probably be lynched by

a mob, anyway. So she lay there.

The practice of burning a widow on her husband’s funeral pyre, known as suttee or sati, was

commonplace in parts of India until the nineteenth century. To allow the dead man’s possessions and

property to pass back into the hands of his family, his widow was expected to commit suicide and

fulfill her duty of chastity by immolating herself on his funeral pyre. Several cases of widows being

drowned or buried alive with their dead husbands have also been recorded. This practice lasted for

2,000 years until the British outlawed it in 1829 on the grounds that it was inhumane and immoral

(see Sharma 1988, 6-7).

Is suttee morally acceptable simply because it was practiced and endorsed by a culture? Are the British

officials who outlawed suttee morally praiseworthy for imposing an outside standard on the native

inhabitants of India and disrupting their ability to fulfill sacred social expectations? Is there a right

answer to the question of whether or not suttee is morally acceptable?

This chapter deals with an important question in metaethics. Metaethics is the branch of ethics that

deals with the nature of morality. It tries to answer the questions: What is morality? Is morality

objective? Where does it come from? What is the relationship between moral facts, if they exist, and

this physical world that we interact with? And so, before we figure out how we ought to be and live,

we must first establish whether there even is such a thing as the way we ought to be and live in the

first place. One of the most important questions in metaethics is whether there is a moral reality that

obligates us regardless of our judgments, opinions, and beliefs and whether there are moral facts that

are necessarily and universally true. Perhaps ethical codes are merely relative to groups of people.

Perhaps there is no true and binding objective morality outside of culture, time period, and personal

preferences. Is morality objective and universal? Or is it merely a matter of opinion and tradition?

R E A L I S M A N D A N T I - R E A L I S M

Think of a time when you disagreed with someone about the right thing to do. Maybe it was a

friend, family member, celebrity, author, or political figure. You may have felt very strongly that X

is obviously the right thing to do, the better course of action, or merely the lesser of two evils. The

person you were disagreeing with might have felt similarly, and perhaps provided reasons for her

position as well. Both of you made claims about morality. You each believed that your own position

was correct or true. But are these claims about morality true or false in the same way that historical

and mathematical facts are true or false?

“George Washington was the thirteenth president of the United States of America” is a false historical

claim because George Washington was not the thirteenth president of the United States of America.

Why is this historical claim false? Because it goes against reality. Similarly, the question before us now

is whether there is such a reality for morals. Are there moral facts that hold true regardless of what

we think about them? Are there moral facts that are true in virtue of some mind-independent moral

reality? Those who say yes fall into the moral realism camp. And those who say no fall into the moral

anti-realism camp.

Moral realism is the position that there are mind-independent facts about ethics that are true and

8 MORAL RELATIVISM

binding even if we have beliefs to the contrary. For example, the moral realist would say that it is

objectively wrong to rape, even if the vast majority of people and cultures believed otherwise—the

truth of “rape is wrong” holds irrespective of our opinions and judgments about rape. Realists disagree

about what grounds or what constitutes the truth of these moral facts, i.e. divine commands, a set of

necessary facts, the nature of sentient creatures, etc. Nonetheless, realists maintain that these moral

facts exist independently of our opinions and judgments.

Moral anti-realism is simply the negation of this thesis. For the anti-realist, there are no mind-

independent facts about morality; morality can be constructed or is merely relative to culture. This

latter version of anti-realism is the position called moral relativism and is the subject of this chapter.

Moral relativism, broadly construed, is the view that ethical codes are relative to the standpoints

of the peoples who embrace them. This can mean many things, which will be discussed below, but

relativists typically hold that ethical truths are relative to culture, that no culture’s ethical code is

superior to another’s, and that we ought not judge other ethical codes as inferior to our own. This

position falls under the category of anti-realism because it denies that moral facts exist independently

of us and argues instead that morality is simply a product of people and cultures.

D E S C R I P T I V E R E L AT I V I S M

The mildest and least controversial form of relativism is descriptive relativism. According to

descriptive relativism, moralities and ethical codes are radically different across cultures—and we

can observe this. For example, some cultures see homosexuality as immoral while others do not;

some cultures think that polygamy is morally acceptable (and should even be encouraged) while

others see monogamy as the moral ideal; some cultures practice slavery while others find slavery

morally abhorrent, etc. This ethical diversity is not only observed and documented now by cultural

anthropologists, but even ancient writers like Herodotus and some ancient Greek skeptics recognized

the different ways that cultures conducted marriage, burials, military discipline, and social

participation. Those who adhere merely to descriptive relativism maintain the view that moral rules

are observably dissimilar across cultures. For some relativists, this suggests the falsity of moral

objectivity and is used as evidence in favor of stronger versions of relativism. Not all relativists argue

that descriptive relativism is evidence against moral objectivity, but relativism often starts out from

the truth of descriptive relativism and makes stronger claims about moral relativity on this basis.

In other words, the observation of differing moral codes across cultures does not necessarily mean

that morality is relative, but some relativists use this anthropological fact as evidence for the stronger

conclusions about relativism that we will look at below.

M E TA E T H I C A L R E L AT I V I S M

The ancient writer Herodotus famously said, “Culture is king” based on his observations of disparate

cultural moralities (Histories 3.38.4) 1 . Upon observing radical differences in the ways that different

cultures practiced religion, burial, household organization, and even eating preferences he concluded

that no standard exists beyond a culture to prescribe good and bad behavior. Thus, culture is king.

ETHICS 9

Unlike descriptive relativism, metaethical relativism makes this kind of stronger claim about the

nature of moral truth. Metaethical relativism says that moral truths are actually only true relative to

specific groups of people. This means that whether a moral belief is true is dependent on, or relative

to, the standpoint of the person or culture that has the belief. Someone in Singapore and someone in

England can both say “It is sunny outside,” but it is possible that the claim is only true for one of them.

In a similar way, metaethical relativism is the position that ethical statements are only true relative to

the context that they are spoken. In other words, when someone claims that some practice, X, is moral,

then the claim is true if her culture believes and lives as if X is moral. For example, if a culture holds

the view that having pre-marital sexual relations is immoral, then for that culture, it is true that having

pre-marital sexual relations is immoral. And for the culture that believes it is morally acceptable to

have pre-marital sexual relations, then “having pre-marital sexual relations is immoral” is false.

Notice that this is different from saying, “Lying might be morally permissible in certain situations

such as when a murderous ax-man asks you where your family is hiding.” Metaethical relativism is not

about this kind of situation-specific method of determining what is moral. Rather it says that moral

beliefs and claims are true or false relative to the cultures or standpoints in which they exist.

N O R M AT I V E R E L AT I V I S M

Finally, we will look at the strongest kind of relativism: normative relativism. It is the strongest

kind of relativism because it goes beyond descriptive and metaethical relativism and makes an even

grander claim. According to normative relativism, no person or culture ought to judge the ethical

codes of other cultures as being inferior, nor should any culture intervene in another culture to

prevent it from carrying out the specifics of its ethical code. The normative relativist says that we

might prefer the specific morality of our culture and even be able to offer reasons for doing so, but

this does not imply that ours is superior to that of others. Normative relativists argue that because

no objective, independent standpoint from which to evaluate ethical codes exists, no culture can

justifiably say that its morality is objectively superior.

On the face of it, this might strike us as problematic for a couple of reasons. Perhaps this principle of

normative relativism itself is only specific to our culture and does not necessarily apply to all cultures.

In other words, just because my culture accepts normative relativism this does not entail that all

cultures must abide by the same principle (of normative relativism) and not consider their moralities

superior. However, if the normative relativist insists that this principle is true for all cultures (that no

culture should judge the moralities of other cultures or consider its morality superior), then this seems

like an admission of a universal value that is true across all cultures irrespective of whether or not they

believe it to be true. Remember that one of the reasons for which relativists deny moral objectivity is

the implausibility of the existence of universal values and moral facts that we can come to know. And

yet, if the normative relativist believes that no culture should criticize the morality of another culture

(and that this principle holds true for all cultures), then this is exactly the kind of universal moral fact

that the relativist denies.

T H E P RO B L E M O F M O R A L D I V E R S I T Y

As we saw in the section on descriptive relativism, the problem of moral diversity is often used as

10 MORAL RELATIVISM

evidence in defense of relativism. Relativism seems to offer a better explanation of why there exists

so much moral disagreement in the world. The moral disagreements also tend to be more profoundly

observed between cultures rather than within cultures. For example, the relativist might point out that

cultures disagree about the morality of homosexuality—homosexual practice is outlawed in a few

countries and is even punishable by death in some (Bearak and Cameron 2016). Perhaps a clearer

example is that of birth control. While some countries have made artificial birth control illegal, 92%

of Americans think that birth control is morally acceptable and most Western nations have legalized

most birth control methods (Gallup 2019; Kirk, et al. 2013). This seems to be a point in favor of

relativism, for if morality is relative to cultures, then we would expect moral disagreements to be most

evident and profound when comparing the ethical codes of different cultures. The more different the

cultures, the more different the ethical codes.

The moral realist who holds that there are objective truths about values has two possible responses

available to the problem of moral disagreement. The first response is to question the scope and

profundity of the moral disagreement between cultures. Some realists argue that the differences

between moralities in cultures are more due to differences in knowledge about the world than to

actual moral disagreement. For example, imagine a culture that practices senicide—the authorized

killing of the elderly. When an individual in the group reaches fifty years of age, they are expected

to undergo a ceremonial honor killing. On the surface, this practice seems to clash with the moral

sensibilities and intuitions of people who don’t engage in this practice.

But suppose one learns some new information, that this group practices senicide because of its

particular views about the afterlife. They believe that one lives on in the afterlife with the same body

that one died with. In order to build huts, find food, and raise a family in the afterlife, then, one must

not have died at such an old age as to prevent one’s body from being useful for these things. For

this reason, the group members ensure that their elderly will be able to successfully overcome the

challenges of the afterlife by ending their lives before their bodies become decrepit.

Now, their practice of senicide is undergirded by the values of care and compassion for the elderly.

Most people might be horrified by such a practice, but the disagreement here is not one of values

and morals but of facts about the world. Those who are horrified may not think that the elderly live

on in the afterlife with the same bodies they died with. If they did, they might not find this practice

so objectionable. The objectivist could thus argue that a lot of the supposedly moral differences we

observe between cultures are more like this case where the disagreement concerns non-moral facts

rather than moral facts.

The objectivist’s second response is to question the main assumption made by the relativist when

arguing from the problem of moral diversity. The relativist’s argument against moral objectivity

comes in two steps: first, she assumes that if there were an objective morality, then there would not be

such moral diversity and second, she then rejects moral objectivity because of the presence of moral

diversity. But why should we grant this first assumption? Why should we assume that if morality is

objective people will not disagree?

Suppose that I give my students a quadratic equation to solve and they all come up with different

answers. Does the presence of many answers entail that there is no right answer? Of course not.

ETHICS 11

In mathematics there is often a correct answer to a problem regardless of whether or not we have

it figured out. If morality works like math in this way, then that might show us that the correct

moral answers are difficult to arrive at, but it certainly does not show that there is no right answer.

The relativist’s assumption that there would be no moral diversity if moral objectivity were true is

demonstrably false.

O B J E C T I O N S TO R E L AT I V I S M

Relative to Whom?

One of the difficulties with moral relativism in general is answering the question of what a culture

is or what counts as an appropriate body of people for morality to be relative to or dependent on. Is

a village a large enough population to have its own valid, ethical code? Or is morality only relative

to national governments and the laws set by them? Perhaps moral subjectivism is the correct form

of relativism, and morality comes down to the judgments of individuals with each individual subject

being enough to form a moral community with an ethical code.

This is a serious problem for relativism because the concept of a culture is so vague and ill-defined

that it becomes almost useless for ethical discussions. Consider the example of the early, abolitionist

movement in the United States prior to the abolishment of slavery: Was it wrong for a group of people

in America to hold anti-slavery views given that the majority of the country was pro-slavery and the

laws reflected such beliefs? Is it wrong for minority groups in other nations to hold views contrary

to popular opinion and written law? If metaethical relativism is true, then a moral claim is true if it

accords with the moral view of the culture and false if it is not. This would mean that the abolitionists

held a false moral view because it diverged from the view of the wider culture.

Perhaps the relativist can respond that the abolitionist movement was large enough to count as a

culture, and is therefore a legitimate moral position even though it differed from the majority view in

that country. But this merely pushes the question back one step further: If the abolitionists numbered

only one hundred members, would this be enough to comprise a culture? What if there were only

twenty? Where if there were only two? One? On what basis does the relativist define “culture” to make

it significant for ethical discussion?

Some Things Just Seem Wrong

The most common responses to relativism come in the form of what is called a reductio ad absurdum—a

form of argument meant to disprove a view by showing us the difficult or absurd (hence the name)

conclusions that the view being responded to would lead to. If the consequences are sufficiently

counterintuitive or ridiculous, then we are justified in rejecting the view as being false. For example, if

I argued that every person ought to be a full-time physician you could respond that if everyone were a

full-time physician, then there would be no full-time politicians, firefighters, police officers, teachers,

humanitarian workers, builders, artists, etc. We cannot have a functioning society if my position were

true. We need more than just full-time physicians to have a coherent society. Thus, my position leads

to absurd consequences, and is certainly false! This next section will first look at three major problems

that relativism faces.

12 MORAL RELATIVISM

If relativism is true, then it is difficult to avoid the conclusion that some obviously wrong behaviors

are actually morally acceptable simply because some cultures practice them. Most people today think

that it is really morally wrong to burn widows on funeral pyres even though it was practiced by a large

group of people at one point. The relativist’s position, however, commits her to conceding that even

practices like suttee, female genital mutilation, infanticide, and slavery are morally acceptable to the

cultures that do not see them as immoral. And because the relativist denies that there are objective

morals or values that hold universally, then there is no independent standard by which to evaluate

behaviors and ethical codes.

Some relativists, like David Wong (2009), see the force of this problem and try to circumvent it

by conceding that some moralities are superior because they better meet the needs of people that

are consistent across all cultures. However, this attempt to rescue relativism seems to undermine

relativism itself! By acknowledging that certain moralities are superior because they do a better job

of helping humans flourish, the relativist has conceded that there exists at least one moral fact that

is true independent of culture or standpoint, namely that human flourishing and well-being are good

and we should aim to maximize them.

If the relativist thinks that this fact is true regardless of what anybody believes about it, and if

the cultures whose moralities better enable human flourishing and well-being are superior to the

moralities or cultures that impede human flourishing and well-being, then this admission deflates the

relativist position. Acknowledging that some moralities are objectively better than others presumes

that there exists some independent standard or set of facts by which we can judge moralities and

ethical codes. Once the admission of some independent condition(s) is entertained then it seems that

we are no longer thinking relativistically but objectively.

Relativism and Tolerance

This last point ties in with another argument put forward in favor of relativism, namely that it

promotes tolerance. Admirably, the relativist wants us to approach the subject of ethics with humility

and not rush to condemning behaviors that are different from ours as immoral. The idea is that

if we acknowledge that no one culture’s ethical code is superior to another, then our ability to

practice tolerance naturally increases, for all moralities are equal. Relativism, it is argued, makes moral

superiority unjustified.

However noble this might seem, it faces the same problem we previously discussed: If all moralities

are equal, then why should we think that tolerance is a universal value? If relativism is true, then

no ethical codes are superior, so why should we think an ethical code that promotes tolerance is

better than the ethical code that ignores tolerance? By arguing that we should prefer relativism on

the grounds that it better helps us promote and justify tolerance, then the relativist has conceded

the existence of at least one universal value that all moralities can be judged by, namely tolerance.

The presence of this universal value—this objective fact about the way we ought to live and

behave—undercuts relativism, itself, for it concedes that there is at least one value that is not relative.

Moreover, tolerance is often an appropriate reaction to interacting with positions, beliefs, and

behaviors that are different from our own. But are not some behaviors and moral viewpoints not

worthy of tolerance? Surely it is appropriate to be intolerant of child abuse, indoctrination, slavery,

ETHICS 13

senseless violence, oppression of the vulnerable, etc. While tolerance is obviously appropriate and

even necessary in some situations, intolerance, and even indignation and moral outrage, are certainly

appropriate and justified in the face of evil.

No Room for Social Reform and Progress

One of the strongest objections to relativism is the idea that if relativism is true, then there can be no

such thing as social reform or moral progress. If each culture’s ethical code is equally good and right,

then when a country changes its ethical code from being pro-slavery to being anti-slavery this moral

change is merely a change rather an improvement. Moral improvement and progress require that

there be some standard toward which a society or an ethical code are approaching; they also entail

that the subsequent morality is better than the prior morality, but again this is not something that can

be said if relativism is true.

When the United States abolished slavery and segregation, and gave women and minorities the right

to vote, its ethical code underwent a change. But to say that it underwent an improvement requires

saying that enslaving African Americans, segregating Whites from Blacks, and preventing women

and minorities from voting are objectively worse, morally speaking, than their opposites. Relativism

cannot consistently support such a position for relativism entails precisely the opposite, namely that

there are no objective standards for morality and morality is relative to communities. If a community

decides that it wants to endorse X and then later decides to morally condemn X, then both moralities

are equal. No morality is superior to another.

However, this seems like another bullet to bite. Relativism implies that certain instances of obvious

moral improvement are merely instances of moral change rather than moral progress. William

Wilberforce’s work to end the slave trade in the British Empire, Martin Luther King Jr.’s life, and

eventual martyrdom, dedicated to advocating equality and eliminating racism, and the countless other

moral exemplars who were able to see past culture, law, and accepted custom to recognize moral

truths that get buried or obfuscated over time really did help bring about moral progress. To say

otherwise seems strongly counterintuitive.

C O N C L U S I O N

Much of the relativism espoused by ordinary people admirably has its roots in the virtues of tolerance

for opposing views and humility about one’s own positions, and in that respect, it can be applauded.

However, this kind of relativism is often endorsed without the appropriate level of critical evaluation

that inevitably shows the inconsistency, unlivablity, and even the immoral consequences of relativism.

Such consequences include:

• Moral progress is impossible.

• Certain obviously immoral behaviors like slavery and oppression of women and minorities

are morally acceptable simply because they enjoy acceptance by a culture.

It’s for these reasons, among others, that according to a 2009 survey only 27.7% of professional

philosophers are anti-realists with only a fraction of those endorsing relativism about ethics (Bourget

and Chalmers 2014, 34). Relativism clashes with much of what seems to be fundamental to the human

14 MORAL RELATIVISM

experience. We cringe when we recall the atrocities of American slavery, the Holocaust, and the Rape

of Nanking. We see the wrongness of these atrocities like we see the rightness of 2 + 2 = 4. Relativism

suffers from several major problems and this should make us question its ability to explain the nature

of morality.

“Thou shalt not commit adultery.” (Exodus 20:14)

“Nor come nigh to fornication/adultery: for it is a shameful (deed) and an evil, opening the road (to other

evils).” (Sura 17:32)

Frustration with moral relativism and subjectivism motivates some thinkers to look to religion for

objective and universally binding moral judgments. If we can ground morality in God, then morality

will be objective, and we can determine with confidence our moral rights and obligations. Moreover,

an answer to the question of why one ought to live morally will be near at hand. This chapter

will examine two forms of religious morality—the Divine Command and Natural Law theories of

morality. We will see that both theories run into serious challenges. In the final section, we will

consider how religious belief and practice might nevertheless support living a moral life.

For the most part, this chapter concerns itself with the Abrahamic religions ( Judaism, Christianity

and Islam, which all have their origins in the prophet Abraham). Box A briefly discusses religion

in non-monotheistic faiths. The Abrahamic faiths conceive of God as personal, omniscient and

omnipotent. God is the creator of the universe, which depends on God for its continued existence.

These faiths also deem God to have given commands, such as the command not to commit adultery.

The total set of these commands is the moral code of the religion. Many people initially learn

morality within religious contexts: in churches, mosques, synagogues and temples, as well as in

families inspired by teachings from these institutions. Often, people defer to religious authorities

or traditions regarding significant moral quandaries, both in their own lives and in their societies,

including abortion, capital punishment, or vegetarianism. Even in liberal societies, people often

consult religious authorities on controversial practical matters. Given that religious thinkers are often

professionally concerned with ethical matters, consulting them does not seem entirely misplaced.

However, even if we acknowledge that religion is connected to morality, there are important issues

that demand philosophical clarification.

We begin with a discussion of the Divine Command Theory of Morality (DCT), which is a metaethical

16 ETHICS

theory—a theory about the nature of ethical reasoning—that sees moral obligation as equivalent to,

and dependent on, the commands of God. We will see that, despite some merits, the DCT is open to

serious and persuasive challenges. We will then move onto a discussion of another form of religious

ethics, the Natural Law Theory of Morality (NLT). Again, while recognizing some merits of this way

of thinking of morality, we will see that it too has some serious weaknesses. Finally, we will consider

some ways in which religious faith might support moral life, even if morality is not dependent on

faith.

BOX A: Non-monotheistic religions and morality

Buddha statue in Phuket by rurik2de via Pixabay. License: Pixabay

The Abrahamic religions (Judaism, Christianity and Islam) agree that God is personal and issues commands to

which we ought to conform. Not all religions accept this way of thinking; some are polytheistic, holding that

there exists a plurality of gods; others do not think of the ultimate reality as personal at all. Hinduism is

notoriously difficult to pin down, but some forms, such as Advaita Vedanta, think of ultimate reality as non-

personal, although others, including Ramanuja’s Vishishtadvaita, hold to a conception of God very similar to the

Abrahamic religions. Some forms of Buddhism accept the existence of gods, but Buddhism does not accept the

existence of a permanent and independent god that is the source and sustainer of the universe. Daoist religions

accept the existence of the Dao, which transcends personal experience, but is understood quasi-naturalistically,

as a fundamental order in the universe. The variations in the non-monotheistic religions mean that it would be

folly to generalize about ethics within these faiths. That said, it is clear that, lacking a personal god, the Divine

Command Theory cannot apply to these religions. Furthermore, Thomas Aquinas’s version of the Natural Law

Theory also cannot apply, for it depends on the designed creation of the world by a personal god. Nevertheless,

Daoism, Buddhism, and some forms of Hinduism, as well as some North American Indigenous religions, might

be thought of as reflecting versions of Natural Law Ethics, inasmuch as they rest on alleged natural facts about

the world.

ETHICS 17

T H E D I V I N E C O M M A N D T H E O R Y O F M O R A L I T Y

The Divine Command Theory of Morality (DCT) is a relatively simple theory of moral obligation that

equates our moral duties to the commandments of God:

• X is morally obligatory if and only if God has commanded X.

• Y is morally prohibited if and only if God has forbidden Y.

Moreover, the DCT holds that God’s commands are the source of morality. Consider, for example, the

seventh commandment, “thou shall not commit adultery.” Assuming that God exists and has indeed

issued this command, then, according to the DCT, it is morally wrong to commit adultery. If God does

not exist or has not issued the command, then adultery is morally permissible.

The motivation behind this theory is obvious: with its universal rules, the DCT at once solves

challenges of relativism and of why one ought to be moral (some argue that the idea of an objective

morality only makes sense if a personal god exists—see Box B). Furthermore, the DCT emphasizes

the idea that moral commands are overriding, in the sense that they trump other motivations such

as convenience or self-interest. Other theories seem deficient in these respects. For example, one

might attempt to support a rule prohibiting adultery on consequentialist grounds (see Chapter 5),

pointing out the likelihood that adultery leads to suffering. However, such reasons will be open

to exceptions—what about situations in which suffering does not ensue? Perhaps one could reject

adultery on deontological grounds (see Chapter 6), using Kantian reasons about the violation of vows

and the lying that typically occurs in adultery, but these considerations might allow adultery in the

case of open marriages. Another possibility is that we reject adultery on cultural grounds, seeing

it as not what “we” do. The DCT, however, makes it clear that if God prohibits adultery, then it

is absolutely wrong whether or not it leads to suffering, violates a cultural norm, or violates the

categorical imperative. Furthermore, the DCT suggests a strong reason to act morally: morality is

essentially submission to the authority of the creator, who may punish transgressors.

BOX B: The moral argument for the existence of God

The DCT tries to equate morality to the purported commands of God. Some thinkers, for instance Robert

Adams (1999), argue that the existence of objective moral obligations is coherent only if a personal God exists.

In other words, the idea is that objective morality either presupposes that God exists, or that the existence of

God is the best explanation of objective moral obligations. Consideration of such arguments, some which can be

traced to Immanuel Kant (1788), would take us too far from the central themes of this chapter. However, see

Evans (2018) for a more detailed discussion of these arguments.

The DCT is interesting in that, in contrast with most other theories of ethical action, it emphasizes

obedience or submission as a central virtue—not obedience in general, of course, but to God and perhaps

to God’s representatives. The idea of moral autonomy, of determining the right course of action

using one’s reason, is not emphasized. One does need to use reason, perhaps to determine whether

an action falls under the scope of a particular commandment, but the principal virtue for the DCT

18 DIVINE COMMAND AND NATURAL LAW THEORIES

is obedience to the will of God. This may for some people be attractive as it offers an escape from

the weighty demands of moral judgment; one essentially transfers responsibility to a third party. One

major religion reflects this idea in its very name: in Arabic, “Islam” means submission, and a “Muslim”

is one who submits (to Allah).

Some theists (people who believe that God exists) might think of the DCT as consistent with their

overall worldview. It may seem that if God has created the world and everything that exists, then God

must have created morality too. Furthermore, if God is omnipotent, then it would seem that God

could choose any morality—we are just fortunate that God chose a morality that facilitates human

flourishing. However, as we dig a little deeper, some serious problems appear.

Some problems arise from the application of the theory to practical decision making. How do we

know what God has commanded? One of the virtues of the DCT is supposed to be its moral clarity,

but the DCT is not so unequivocal as it appears. First, the DCT presupposes that we have the right

religion, and also that we interpret that religion correctly. Clearly, this is going to make it very

challenging to apply the DCT to issues that demand agreement with those of diverse or no faith.

Second, how can we resolve issues that arise from applying ancient commands to contemporary

moral problems, including problems arising from human cloning, pornography, assisted suicide, or

nuclear weapons? Minimally, we will need to use our judgment to determine what the commands

suggest God would have commanded, but this will render obedience less clear. Third, to make

matters worse, God has issued multiple commands, sometimes leading to dilemmas in which we are

commanded to do two incompatible actions. What if the only way to “honor thy parents” is to “bear

false witness,” or if keeping the Sabbath holy will require violating the duty to honor thy parents?

Supporters of the DCT can develop responses to these problems of application, but the cost will be

that the theory will lose its simplicity, one of its chief attractions. However, even if we put these

challenges aside and agree that we know that God has, for example, forbidden adultery, there remains

a still more fundamental challenge to the DCT.

The challenge is sometimes called the “Euthyphro dilemma,” as it is expressed in Plato’s Dialogue

Euthyphro (see Box C). To understand the challenge, suppose that God exists and has forbidden

adultery. Then, adultery is immoral, according to the DCT. However, is adultery immoral because

God forbids it? Or does God forbid adultery because it is immoral? Whatever our response, puzzles

arise.

ETHICS 19

BOX C: The Euthyphro dilemma

Plato’s Euthyphro is written from the context of polytheistic religion, and is concerned with the idea of piety or holiness, which may not be precisely the

same as the idea of moral rightness or moral good. In a dialogue with Euthyphro,

the participants inquire into the nature of piety. When Euthyphro suggests that

piety is that of which the gods approve, Socrates (after reflection on the issue of

disagreements between the various gods) asks whether X is pious because the

gods approve of X, or whether the gods approve of X because X is pious. The

question is a gem in philosophy: Socrates is expressing a puzzle that is often

called a dilemma because neither option is satisfactory for the believer.

On the one hand, if God forbids adultery because it is immoral, then God has reasons for the

command. 1 We could suppose that God is broadly consequentialist and forbids adultery because of

the bad consequences to which it leads. Or perhaps God forbids adultery because it violates a promise

typically made in marriage vows, a consideration that we could cast in broadly Kantian terms. Either

way, if God appeals to either consequentialist or Kantian principles, it follows that theoretically at

least, humans could determine that adultery is immoral without knowledge of God’s commands. This

response to the Euthyphro dilemma implies that the source of morality is not God’s commands; while

these commands may be helpful, they are logically redundant: our moral duties are equivalent to the

commands of God, but they are not based on God’s commands. Consequently, taking this stance on

the Euthyphro dilemma implies that morality is logically independent of God.

Note that this response denies neither that God forbids adultery, nor that adultery is immoral. It

rather holds that there is a deeper reason for the command forbidding adultery. If God applies perfect

reason to determine which actions are forbidden or required, then the principles on which God relies

are the ultimate source of moral obligation.

Still, we might acknowledge that human reason is often imperfect, short-sighted or overly self-

interested. The consequences of our actions are often unforeseeable, 2 but God’s omniscience permits

more accurate, if not perfect, predictions of the consequences of our actions. 3 So, while in one

sense redundant, God’s commands ought not to be ignored; they are based on superior reason and

knowledge, and thus can be a more reliable source of moral knowledge than our own reason—indeed,

this is known as God’s providence. However, to respond to the Euthyphro dilemma by affirming that

God forbids adultery because it is immoral effectively rejects the DCT. It would mean that God’s

commandments are based on morality. However, from the DCT’s standpoint, this cannot be true.

1. Note that the Qur’anic version of the rule against adultery (above) suggests that God forbids adultery for reasons.

2. “Cluelessness” is a well-known problem for consequentialist theories in general. See Greaves, Hilary. 2016. “Cluelessness.”

Proceedings of the Aristotelian Society 116(3): 311-339.

3. There is an interesting problem of whether God has absolute knowledge of the future, if it is true that humans have free will. Theists

clash on this issue.

20 DIVINE COMMAND AND NATURAL LAW THEORIES

On the other hand, suppose we affirm that adultery is immoral because God forbids it. Then, from our

human point of view, it is objectively wrong to commit adultery, but from God’s point of view, there is

no moral reason to forbid adultery. If God has a reason for forbidding adultery, then we are implying

the existence of another source of morality, thus bringing us back to the independence option.

However, if adultery is wrong because God forbids it, then we must accept that God’s commandments

are arbitrary. God does forbid adultery, we might say, but God might as well have allowed it on special

days—say, on one’s birthday or on blue moons. As bizarre as these options seem, they are candidates

from God’s perspective. The fact that we consider these options “bizarre” is a sign that we presuppose

that there are reasons for rejecting adultery that have nothing to do with God’s commands.

So, the options seem to be that either God has reasons for issuing commands or God does not.

If God does have reasons, then we seem to be forced to admit some deeper principles on which

God’s commands are based. This is the independence option. If God does not have reasons for the

commands, then the commands are arbitrary. Neither alternative is attractive, thus giving us reason to

reject the DCT. However, some thinkers, including Christian philosopher William Lane Craig, argue

that the Euthyphro presents a false dilemma, which is the fallacy of assuming that there are just two

options when in fact there are multiple options.

Craig argues that God is essentially good, meaning that goodness is part of God’s nature:

There’s a third alternative, namely, God wills something because He is good. What do I mean by

that? I mean that God’s own nature is the standard of goodness, and His commandments to us are

expressions of His nature. In short, our duties are determined by the commands of a just and loving

God. (Craig 2010, 135-6)

Craig is arguing that moral rules are neither independent of God, nor are they arbitrary. The

command not to commit adultery is based on God’s own goodness; it is therefore not arbitrary. Nor

is the command independent of God, as it is only through the good nature of God that the command

occurs in the first place.

In response, we can note that the claim that God is the “standard of goodness” does not really escape

the problem. Consider Craig’s assertion that God is “just and loving.” If one says this about another

person, then the claim is meaningful; this person satisfies the independent standards of being loving

and just. However, if “God’s own nature is the standard of goodness,” then saying that God is “just

and loving” means that whatever God does would be equally just and loving. This seems to be the

arbitrariness option, albeit in disguised form. So, it is unclear how Craig’s idea presents a third option.

A stronger and more subtle response to the Euthyphro dilemma comes from the work of Robert

Adams (1979), who has proposed a less extreme version of the DCT, which he calls the Modified

Divine Command Theory (MDCT). Recall, the DCT holds that to say X is morally wrong is to say

that God has forbidden X. This is usually understood as implying that God’s commands are the source

of our moral obligations. Indeed, that is how we have been considering the theory so far. However,

Adams understands the DCT as articulating the equivalence between our moral obligations and the

commands of a loving God. Thus, to say that one must not commit adultery is to say that a loving God

commands us not to commit adultery. Adams’ MDCT does not insist that God’s commands are the

source of moral obligation. Indeed, Adams’ position begins from a stance of confidence in basic moral

ETHICS 21

facts, such as the wrongness of causing unnecessary suffering, arguing that the existence of a loving,

intelligent God is the best explanation for those objective moral facts.

Adams’ MDCT is an example of how philosophical theories respond to criticism, such as the

Euthyphro dilemma. Adams accepts that the arbitrariness of God is not tolerable, but does not give

up the DCT entirely. Rather, he reimagines the theory as insisting on the identity of moral rules with

God’s commands, but gives up the idea that the source of morality lies in the arbitrary commands of

God. The strategy is promising but we should note that Adams has given up the idea that adultery, for

example, is wrong because God forbids it.

T H E N AT U R A L L AW T H E O R Y O F M O R A L I T Y

The DCT is still embraced by some theistic thinkers today, often in a modified form such as Craig’s

or Adams’. However, many theists argue for a different conception of the relationship between God

and morality. One important theistic moral tradition is the Natural Law Theory of Morality (NLT).

This approach to morality does not deny that God issues commands, but instead takes morality to

be implicit in God’s creation of the universe and rational human beings. The idea is that the universe

is created by God with everything holding a natural purpose. These purposes can be determined by

careful study, using our reason. From knowledge of the proper purposes of objects, one can identify

the proper ways to interact with the world and each other.

The moral theology of Thomas Aquinas (1225-1274 CE) contains one influential version of the

NLT. Aquinas derives his underlying metaphysics from Aristotle (384-322 BCE). For Aristotle,

understanding any object requires knowing four aspects of it. We must know of what it is made (its

material cause), its form (formal cause), how it came to be (its efficient cause), and its function (its final

cause). Consider rain, for example. The material cause of rain is water; its formal cause is droplets of

liquid falling from clouds; and its efficient cause is the condensation of vapor along with the force of

gravity. Its final cause can be thought of as its functions of watering plants and refilling the streams

and lakes from which we drink. As it turns out, science today has progressed greatly by rejecting

final causes, but for centuries western science was influenced by the Aristotelian idea that in order

to understand X we need to know what X is for. In Aristotelian terms, the function of an object will

be understood as how it fulfills functions within the system to which it belongs—teeth allow us to

chew food, the heart functions as a pump to circulate the blood. The NLT easily bends the idea of an

object’s function into its purpose, which further suggests how it ought to be used. Briefly, there are three

components of this approach to morality:

1. God created the universe, including human beings and other objects, with purposes.

2. The purpose of objects in the world can be discerned using natural reason, with which God

has endowed human beings.

3. The purpose for which God created an object determines its proper use.

The upshot is that our capacity to discern God’s purposes in creation provides us with awareness of

our ethical obligations. One of the strengths of the NLT is that it allows us to perceive God’s purposes

without knowing God’s commands, or even believing that God exists.

22 DIVINE COMMAND AND NATURAL LAW THEORIES

For example, our reason allows us to identify that our sexual organs have the function of reproduction

of our species. Indeed, for Aquinas, something can have just one final cause. So, reproduction is

why God provided our sexual organs to us. If sexual organs are created solely in order to fulfill

reproductive needs, then it would be wrong to use them for other purposes. In general, sex for

pleasure becomes problematic, but especially so when reproduction is either impossible or thwarted;

thus, homosexual acts, mechanical or chemical birth control, and masturbation are all ruled out on

this account. These acts constitute use of sexual organs in ways that could not lead to reproduction.

If we add the insight that marriage functions to provide a legitimate outlet for sexual needs and as a

space for rearing children, then it will be clear that adulterous sex will also be wrong.

Aquinas’s version of the NLT is clearly theistic, as it presupposes the existence of an intelligent

designer of the universe who has endowed us with the capacity to discern the natural law. However, it

does not suggest that acts are right or wrong according to God’s arbitrary commands. Instead, it takes

the position that when God commands us to do X, it is because X is right. Further, we do not need to

believe in God in order to know what is right or wrong. Anyone, theist or not, is able to identify the

laws of nature that govern morality, because these are implicit in nature itself. Why then would God

give us commandments?

One reason is that God is able to infallibly identify the consequences of our actions. Human beings

can predict the consequences of our actions (“if I shoot the gun at the man, then he will probably be

killed”), but God’s omniscience implies infallible prediction. God even will be able to anticipate the

consequences of our actions into the afterlife. Also, while God’s reasoning is impeccable, our own

reasoning is subject to error, so we can use God’s commands as a failsafe that reliably allows us to

determine the right course of action. So, if God has commanded us to do X, then under the NLT we

should do X.

Still, the NLT is problematic. First, it presupposes a model of explanation at odds with today’s

successful scientific reasoning. Science can proceed without identifying purposes in nature. Indeed,

the onset of the scientific revolution is dependent on rejecting insistence on Aristotelian final causes.

It is true that there are examples of functionalist reasoning in some areas of the life and human

sciences—as when we say that the heart serves as a pump, but there is a significant difference between

an object’s function and its purpose. The latter idea presupposes an intelligence that creates or guides

the object in question. Second, the idea of an object’s function is not as clear as the theory suggests.

Even if we allow that sex is for reproduction, it does not follow that it is only for reproduction, or

that it could not be used for other purposes. Sex could be used to enhance intimacy, or perhaps

just as a form of amusement, even if we allow that it also has the function of reproduction. Some

proponents of the NLT will respond to this line of thinking in interesting ways, developing, for

example, a doctrine of double effect (see Box D).

ETHICS 23

Box D: The Doctrine of Double Effect

The Doctrine of Double Effect was originally proposed by Aquinas in Summa Theologica (II-II, Qu. 64, Art.7) in his defense of killing another person in self-defence. The basic idea is that it is okay to kill an attacker in self-

defence, providing that one does not intend to kill—the killing must be a side-effect of one’s action, not its

intention. This doctrine is often applied in cases of end-of-life care, where perhaps one acts in order to alleviate

pain in a patient, but the action has the foreseeable, albeit unintended, consequence of causing the death of the

patient. See McIntyre (2014) for a discussion of this doctrine.

A third and decisive challenge to the NLT is that it commits the naturalistic fallacy. British philosopher

G. E. Moore (1873-1958), who introduced the term, argues that it is fallacious to infer claims about

what is good or right (moral properties) from claims about natural properties (Moore [1903] 2004).

Moore specifically offered the inference from something being pleasurable to it being good as an

example. Earlier, David Hume (1711-1776) argued that claims about what ought to occur cannot

be inferred from claims that describe the world; we cannot infer an “ought” claim from purely “is”

claims (Hume [1739] 2009). The important differences between Hume’s and Moore’s positions need

not detain us too much here; what we need to note is that the NLT would have us describe the world

in purely naturalistic terms, then infer something about how the world ought to be. We observe, for

example, that sex has an essential role in reproduction, then infer something about the proper role of

sex. If either Hume or Moore are correct, such inferences are illegitimate, because the conclusions of

our inferences include concepts that are not implicit in the premises. The challenge, in Moore’s terms,

is that the NLT implies that goodness or rightness are natural properties, whereas in fact they are

properties of an altogether different type.

R E L I G I O U S M O R A L I T Y

So far, we have been considering the relation between God and the content of our moral obligations,

the actual rules governing what actions we ought to perform. However, even if we conclude that our

moral duties are independent of religious belief, we could still insist that religious faith contributes

to living a moral life. In other words, religious practice might support our moral life in ways that are

independent of determining how we ought to act.

An obvious point is that fear of divine punishment provides a powerful motivation for doing the right

thing. Clearly, if the only reason one does not succumb to the temptation to murder is one’s fear of

hell, then we can be glad that one has those religious beliefs! However, it seems that morality requires

doing the right thing for the right reason, 4 so we might want to insist that such action is not truly moral

action.

More interestingly, faith and religion are more complex than simple adherence to a set of doctrines.

Usually, religions are social institutions that have long histories that include stories of moral heroes

(saints, prophets, etc.) contributing to our moral understanding. Furthermore, religions usually

provide moral codes that enjoin us to proceed beyond the customary demands of the morality of

4. See Kant (1785) 2002, Groundwork for the Metaphysics of Morals for a defense of this idea (also discussed in Chapter 6).

24 DIVINE COMMAND AND NATURAL LAW THEORIES

the times, as when the Qur’an advises us to seek knowledge (Sura 20:114) or appreciate diversity

(Sura 49:13). The Buddha advises us to develop compassion, and Christ demands that we love our

neighbour; Guru Nanak insists on women’s equality from the beginnings of the Sikh faith. Even

if adherents often fall short of these ideals, the ideas encourage us to move beyond what has been

typically expected of people—in some cases, helping us to reconceive our moral relationships to those

who have traditionally been left out of our moral thinking.

We should also recognize that as social institutions, religions provide support for others, both within

and without the religion. Religions offer charities that support poverty alleviation, such as World

Vision or the Aga Khan Foundation. These same charities offer opportunities for the adherent to

make a moral difference in the world. Such voluntary work permits the individual to develop moral

sensitivity and even courage. It will often allow the adherent to escape from the self-centeredness that

so epitomizes much contemporary life. Indeed, the great twentieth-century philosopher of religion

John Hick (2005) thinks of religions as mainly concerned with providing means by which we move

beyond self-centeredness.

Another interesting idea to consider is what Robert Adams (1979) calls the problem of

“demoralization” without religion. Adams, drawing on some enigmatic ideas from Kant’s Religion

Within the Limits of Reason Alone ([1793] 1960), suggests that the moral agent needs to have a sense that

her moral actions will be effective—“contribute to a good world-history”—but this presupposes “a

moral order of the universe.” Such an order, he argues is best, but not exclusively, offered by a theistic

religious belief.

The idea is that the world presented to us by contemporary scientific understanding is a morally

indifferent world, in which the agent has no guarantee that things will work out in the end, that one’s

moral efforts are not in vain. Such a world is demoralizing inasmuch as it leads to questions about

the point of moral life. The world presented to us by most theistic religions is one in which moral life

will, ultimately at least, lead to a better world, for oneself as well as others. As such, religions make the

sacrifices, demands and frustrations of moral life more attractive.

In response, we can agree with Adams that religion might make moral life more attractive for

some people but insist that his argument does not support the stronger position that living morally

demands religious faith. Quite clearly, there are millions of people who live moral lives without the

assurance of a moral order in the universe brought about by religion.

This chapter explores a variety of approaches to the question of moral virtue and what it means to be

a good person. It examines four ethical systems that revolve around the concept of virtue: Aristotle’s

virtue ethics, Aquinas’s Christian version of Aristotelian virtue ethics, Buddhist virtue ethics, and

Daoist and Confucian virtue ethics. Each will be presented as a different way of understanding what

it might mean to live as a good person. For Aristotle, this is to be understood in terms of striving for

the mean between extremes in the context of a well-ordered political community. For Aquinas, it is to

be understood within the context of Christianity and natural law. For Buddhism, virtue is understood

in terms of a life oriented toward the eightfold path that leads to the end of suffering. For Chinese

philosophy, both Daoist and Confucian, virtue means being in harmony with the Cosmic Dao.

W H AT I S V I RT U E E T H I C S ?

In philosophies of virtue ethics, rather than an emphasis on following rules, the emphasis is on

developing oneself as a good person. It is not that following rules is not important; it is more the sense

that being ethical means more than simply following the rules. For example, given an opportunity

to donate to a charity, deontologists (see Chapter 6) would consider whether there is an ethical rule

that required them to donate. Utilitarians (see Chapter 5) would consider whether a donation would

produce better consequences if they donated than if they did not. Virtue ethicists would consider

whether donating is the kind of action that a virtuous person would do. Another example would

be deciding whether to lie or tell the truth. Rather than focus on rules or consequences, virtue

ethicists ask what kind of person do they want to be: honest or dishonest? Virtue ethicists place more

importance on being a person who is honest, trustworthy, generous and other virtues that lead to a

good life, and place less importance on one’s ethical duty or obligations. A common theme among

virtue ethicists is stressing the importance of cultivating ethical values in order to increase human

happiness. Businesses today increasingly incorporate virtue ethics in their work culture, often having

a “statement of values” guiding their operations.

Because the right ethical action depends on the particularities of individual people and their particular

situations, virtue ethics links goodness with wisdom because virtue is knowing how to make ethical

decisions rather than knowing a list of general ethical rules that will not apply to every circumstance.

Virtue ethicists tend to reject the view that ethical theory should provide a set of commands that

dictate what we should do on all occasions. Instead, virtue ethicists advocate the cultivation of

wisdom and character that people can use to internalize basic ethical principles from which they

can determine the ethical course of action in particular situations. Virtue ethicists tend to see ethical

principles as being inherent in the world and as being discoverable by means of rational reflection and

disciplined living. The different forms of virtue ethics may or may not focus on God as the ultimate

source of ethical principles. What unites the various forms of virtue ethics is the focus on moral

education to cultivate moral wisdom, discernment, and character in the belief that ethical virtue will

manifest in ethical actions.

A R I S TOT L E O N E XC E L L E N C E A N D F LO U R I S H I N G

The ancient Greek philosopher Aristotle (384-322 BCE)

believed that to understand something we need to

understand its nature and proper function (see Chapter 2).

He also believed that everything has an end, or goal,

toward which it naturally moves. For example, a seed

grows into a tree because the purpose and function of the

seed is to grow into a tree. Objects fulfill their purpose,

not out of conscious desire, but because it is in their

nature to fulfill their functions. Aristotle believed that our

purpose is to pursue our proper human end, eudaimonia,

which is best understood as human flourishing or living

well. Eudaimonia is not momentary pleasure but enduring

contentment—not just a good day but a good life. Aristotle

said that one swallow does not make a summer, and so,

too, one day does not make one blessed and happy. It is

human nature to move toward eudaimonia and this is the

purpose, function, or final goal (telos) of all human activity.

We work to make money, to make a home, and we

sacrifice to improve our future, all with the ultimate aim

of living well.

Human flourishing means acting in ways that cause your

essential human nature to achieve its most excellent form of expression. Aristotle held that a good life

of lasting contentment can be gained only by a life of virtue—a life lived with both phrónesis, or

“practical wisdom,” and aretē, or “excellence.” Aristotle defines human good as the activity of the soul in accordance with virtue, and wrote in the Nicomachean Ethics that

we take the characteristic activity of a human being to be a certain kind of life; and if we take this kind of life

to be activity of the soul and actions in accordance with reason, and the characteristic activity of the good

person to be to carry this out well and nobly, and a characteristic activity to be accomplished well when it is

28 VIRTUE ETHICS

accomplished in accordance with the appropriate virtue; then if this is so, the human good turns out to be

activity of the soul in accordance with virtue. (1.7) 1

The ethical demand on us is to develop our character to become a person of excellent ethical wisdom

because, from that excellence, good actions will flow, leading to a good life. Virtuous actions come

from a virtuous person; therefore, it is wise to focus on being a virtuous person.

For Aristotle, ethics is a science with objective rational principles that can be discovered and

understood through reason. Whether a particular course of action is good or not, and whether a

person is good or not, are ideas that can be understood objectively. The cultivation of virtue must be

accompanied by a cultivation of rationality. Aristotle saw the human soul as having three components:

the nutritive part, responsible for taking in nutrition; the sensitive and appetitive part, responsible

for sensing and responding to the environment, including the desires and appetites that motivate

actions; and the rational part, responsible for practical and productive intellect. All three components

are essential to being a human, but they exist in a clear hierarchy, with the faculties of reason at the

top; these can and should control and guide the appetites into productive and ethical actions. Aristotle

characterizes the desiring and emotional part of the soul as partaking of reason insofar as it complies

with reason and accepts its leadership. The person of good virtue has cultivated a stable soul that is

not swayed by appetites or desires but is governed by reason. Being ethical, then, is a skill that one

develops. Just as you can through practice become good at math or playing a musical instrument, you

can through practice become a virtuous person. When you have reached a certain level of skill in math

or playing music, you no longer need a teacher to guide you, and you quickly can understand what

to do. The same is true in Aristotle’s conception of ethical decision making—it becomes an ingrained

habit.

How can the rational human come to understand what proper ethical actions are? Aristotle’s answer

is his doctrine of the mean, or the balanced course of action:

Virtue is a state of character concerned with a choice, lying in a mean relative to us, this being determined

by a rational principle, and by that principle by which the person of practical wisdom would determine it.

(Nicomachean Ethics 2.6)

We see here Aristotle’s emphasis on a virtuous character that enables us to make a rational ethical

choice. There are two important aspects of this. The first is the concept of the choice lying in a mean

relative to our circumstances, and the second is that what the mean is in any particular situation

can be determined by the person of practical reason. The ethical course of action is relative to our

particular circumstances, meaning that there is not one rule that fits all situations, but the ethical

course of action is objectively true in that any rational person looking at the situation will be able to

understand the correct ethical course of action.

By the mean, Aristotle refers to something midway between two extremes. The virtuous act is the one

that falls between the extremes of what is deficient and what is excessive relative to the situation.

1. References to Aristotle are formatted using the book and chapter of the text. This citation, for example, corresponds to Book 1,

Chapter 7 of the Nicomachean Ethics.

ETHICS 29

All of the moral virtues are a mean between harmful extremes (too little, too much) in our actions and

emotions:

Sample virtues as means between extremes

Too Little Mean (Virtue) Too Much

Cowardice Bravery Foolhardiness

Stinginess Generosity Profligacy

Self-ridicule Confidence Boastfulness

Apathy Calmness Short-Temperedness

Sometimes the mean lies closer to one extreme than the other because of the particular circumstances

involved. Because situations are different, it is not sufficient to say, “Be brave” because the mean of

bravery differs from situation to situation. There are still ethical standards, but they are relative to the

situation. It is always wrong to eat too much, but “too much” will be different for each individual. That

is why an emphasis on virtue—the ability to discern how to make ethical decisions—is the key to an

ethical, good, and balanced life that is worth living.

The better you are at finding and acting on the mean, the more you have phrónesis (“practical wisdom”).

This form of practical reason helps one recognize which features of a situation are morally relevant

and how one can do the right thing in practice. Practical reason is rational because it is open to

rational influence. Again, virtue is a learned skill. A person who listens to and learns from the reason

of others is a rational person, and the same holds for ethics. As Aristotle sees it, every thought that

one has, and action that one takes, contributes to the development of either a virtue or a vice. Virtues

such as temperance, courage, and truthfulness become increasingly a part of our actions the more we

intend to do them and the more we practice doing them. The truly virtuous person:

• Knows what she or he is doing.

• Chooses a virtuous act for its own sake.

• Chooses as a result of a settled moral state.

• Chooses gladly and easily.

These are possible only through developing a virtuous disposition in which the soul is settled by

reason. The more you practice virtue, the more you are capable of virtue because virtue becomes a

way of life. Leading an objectively rational good life will produce a subjectively happy life of the kind

appropriate to being human.

Most of Aristotle’s writings were lost to Western

Europe up until the twelfth century. When Islam

spread across Egypt, the Levant, and Persia in the

seventh century, libraries of old Greek writings were

found, including works of Aristotle lost to the Latin-

speaking world. Ibn Sina (Avicenna), Ibn Rush

(Averroës), and other Islamic thinkers recognized the value of Aristotle and wrote commentaries on his

works and other works extending his philosophy.

Those Islamic works were discovered by Christians

when they conquered central Islamic Spain in the mid-

twelfth century. Like their Islamic counterparts a few

centuries earlier, Christian scholars knew what they

had in the Islamic libraries. Works by Aristotle (who

the Christian scholars knew from his logic books) were

eagerly translated into Latin and distributed widely.

Aristotle’s texts posed problems for Christian

philosophers in reconciling them with Christian

theology, which led to many arguments within the

thirteenth-century Catholic Church. Enter Thomas

Aquinas (1225-1274), who wrote the Summa Theologia

(The Sum of Theological Knowledge), creating a

system that could, as advertised, provide answers to all

questions. Aquinas’s philosophy was based on the

writings of Aristotle, who he reverently called “The Philosopher” and placed as a source of truth

almost on the same level as the Bible. You will see similarities between Aristotle’s and Aquinas’s ethical

systems.

Like Aristotle, Aquinas based ethics on the pursuit of our proper human end. Unlike Aristotle,

Aquinas believed that our proper human end of eudaimonia is not found in this world. Aristotle’s

system, Aquinas believed, was as good as humans could achieve on the basis of the natural realm,

but our end as humans is to be perfected through union with God. For Aquinas, every event occurs

because there is some end toward which things are directed, and we humans, like everything else

in the universe, have our own ends. Unlike everything else, we as humans can consciously choose

which ends we pursue, and ethics concerns which ends are worth our efforts to pursue. Like Aristotle,

Aquinas believed that ethical understanding comes through virtue and that virtue is a skill that must

be developed. Also like Aristotle, Aquinas believed that we learn what is ethical through our reason,

which we can use to uncover God’s natural law that is imbued in creation. By rationally reflecting on

what is in accord with nature and our own natural inclinations, we can understand the ethical virtues.

Aquinas’s Aristotelian idea that humans can rationally understand ethical principles had to deal with

the Christian concept that humanity’s sinful nature prevented such understanding. He held that sin

ETHICS 31

affects our moral life but not our rational life, clearing the way for the use of our human intellect

to learn ethical truths. He borrowed from Islamic philosophers the conception that intellect is both

passive and active. Intellect passively takes in sense experience and ideas but actively processes

them to abstract universal truths. This is a natural process that is inherent in the human mind

without requiring illumination from God and that is unaffected by sin (as was commonly taught in

Aquinas’s time). The universals abstracted by the mind from multiple individuals (e.g., “triangle” can

be abstracted from individual triangles) are tied to real features in the world, the universals created

by God and first existing in the mind of God, who used them to create the objects in the world. Put

simply, we use our intellect to understand the world God has created. It is an orderly and purposeful

world, with all of the objects in it receiving their purpose from God. By observing the world and

reflecting on our observations, we can learn about the natural world, including God’s ethical laws,

which permeate the natural world. Aquinas used this conception to develop what we now know as

“natural law”—the idea that ethical truths are ingrained in nature (see Chapter 2 for more on Aquinas’s

view of natural law).

To be virtuous, we need to learn God’s natural law that governs the motion of objects in nature

and instructs us in ethical behavior. To be rational, which is central to our human ends, requires

intellectual discipline, but it is the way to virtue. Through self-discipline and reflecting on the natural

law, we learn and develop as ingrained habits the four cardinal virtues of temperance, courage,

prudence, and justice. Virtuous persons practice the four cardinal virtues in their daily lives, and from

those virtues flow ethical behaviors in all situations.

Buddhism is a spiritual and philosophical tradition founded by Siddhārtha Gautama in India in the fifth century BCE. There are many schools of Buddhist thought in many countries, from monasteries

devoted to religious ritual devotion to solitary practitioners of meditative practices. A common thread

among most Buddhist schools of thought is an emphasis on a virtue ethical system that teaches

the art of becoming balanced and harmonious through humility, with the goal of being free from

dukkha, or suffering or anguish. We can free ourselves from suffering by extinguishing hatred and

ignorance, following the teaching of the founder of Buddhism, Siddhārtha Gautama, who became “Buddha,” which means “the Awakened One.” Siddhartha Gautama taught that what could be called

evil acts are performed out of ignorance and fear; therefore, rules and threats of punishment do not

curtail these acts. We learn how to act in a suitable way (sammā, meaning best or most effective in the circumstances) by focusing on thinking suitably because our thoughts lead to our actions. The

emphasis in Buddhism is on what is suitable and unsuitable rather than on the Western sense of right

and wrong or good and evil. A life of virtue is outlined by the eightfold path: suitable view, intention,

mindfulness, concentration, effort, speech, bodily conduct, and livelihood. By making one’s thoughts

and actions suitable, one promotes positive outcomes and lessens harmful outcomes. This is especially

important to Buddhists because of the Gautama’s teaching about karma, a concept that underlies

Buddhist ethics and differs significantly from the divine command ethics found in many religions.

The idea of karma is that it is a natural phenomenon that we can think of similarly to how we think

of the laws of physics. The law of karma says that thoughts and actions that intend to harm others

will eventually cause harm to ourselves and that thoughts and actions that intend to benefit others

32 VIRTUE ETHICS

will eventually benefit us. In the Buddhist conception of time, “eventually” could mean in a future

life that is multiple reincarnations away, so Buddhists think less in terms of immediate consequences

of thoughts and actions and more in terms of the intrinsic value of them. Karma is not a strict

determinism in that we still have free will and can mitigate the consequences of karma through our

virtuous thoughts and actions. To avoid future suffering in this life or future lives, a Buddhist focuses

on developing inner virtue to be able to think and act suitably in order to avoid negative karma, and

to generate positive karma. As with Aristotle’s virtue ethics, the more you practice virtue, the more

you are capable of virtue. Having made a commitment to follow the eightfold path as a way of life, you

are disposed to follow those rules.

For more than two millennia, Chinese philosophy has been dominated by two great traditions,

Confucianism and Daoism (Taoism), that have influenced China throughout its history and are

important to Chinese culture still to this day. Both traditions are founded on their teaching of the

Dao, which is best translated as “the way.” Dao is both noun and verb, both how the universe is and

how things behave properly. The Dao cannot be described completely in words but can be sensed as

the source of all things and the rhythm of Being. All things come from Dao, and all things have their

own Dao, or essence, which comes from the Cosmic Dao. Adepts of both Confucianism and Daoism

believe that to be in the Dao and in harmony with it is to be virtuous and at peace, and that this state

of enduring harmony with the Dao, similar to Aristotle’s eudaimonia, is the proper human goal. Both

Confucianist and Daoist ethical systems teach that a community flourishes when its members are in

harmony with the Dao, and that the state flourishes when its leaders are in harmony with the Dao.

However, Confucianism and Daoism are in disagreement about how communities and governments

can keep in harmony with the Dao and, thus, promulgate different ideas about how to attain virtue.

ETHICS 33

Confucianism is the social and ethical system set

down by Kongzi (Master Kong) (c. 551-479 BCE),

known in the West as Confucius. Kongzi saw the

virtuous person as an artistic creation achieved

through the diligent practice of ethical excellence by

way of strict ritual practice. Ritual, or Li, is the art and

practice of crafting one’s character from the raw

material of human nature. Just as a craftsperson uses

tools to fashion wood or stone, a person uses ritual

behaviors to carve and polish his or her character. Li

extends to all aspects of life; Kongzi taught that our

every action affects our character and our

environment, so every activity needs to be performed

with the proper respect and procedures. Kongzi

issued hundreds of rites in sayings covering many

aspects of human life, how youth should behave

toward their parents, what colors of clothing one

should wear and when, how one should greet another

person, protocols that should be observed at the court

of the ruler, and so on—all to be strictly observed in

order to cultivate the comprehensive ethical virtue

known as Ren.

Most of the rites specified by Kongzi concern human

interactions, reflecting the great importance he

placed on suitably respecting one’s superiors. Ancient Chinese society was highly stratified, and

Kongzi thought that maintaining the social hierarchy was essential to social order. Showing respect

for one’s superiors, such as government officials, elders, and ancestors, was more than polite; it was

essential for society to function properly. Filial piety was more than respecting your family elders

dead or alive; it was the fundamental building block of social harmony and justice. The more one

practiced the rites, the more one developed virtue, most importantly the virtue of Ren or benevolence.

Ren should be understood not as acts of kindness but as acts of propriety that create virtue in oneself

and society. Practicing the rites virtuously brings each person and society in harmony with the Dao

and leads to a good life for all.

The philosophy of Daoism has long provided a strong counterpoint to Confucianism. As the name

implies, Daoism focuses on harmony with the Dao rather than on human teachings, the opposite

of the Confucian emphasis on a system of ritual behavior. Daoist ethics centers on the fundamental

virtue of wu wei, meaning “effortless action.” Daoism rejects formal ritual and deliberately striving for

virtue, emphasizing instead that virtue comes from naturalness, simplicity, and spontaneity. Daoism

at times seems to be anti-civilization with its calls for us to detach from the artificiality of social

traditions and rituals and to adopt instead a quiet life communing with nature. At other times, though,

Daoism attempts to reform society, especially its leaders:

If you want to be a great leader, you must learn to follow the Dao. Stop trying to control. Let go of fixed plans

34 VIRTUE ETHICS

and concepts and the world will govern itself. The more prohibitions you have, the less virtuous people will

be. (Laozi [ca. 400-250 BCE] 1991, Chapter 57)

The Daoist idea is that separating ourselves from nature is separating ourselves from the Dao and

that what most contributes to this separation from the Dao are the social institutions of government,

military, and other social hierarchies and power structures. The Daoist virtue of wu wei involves a

life of walking away from the artificial trappings of human pretension and arrogance and shaping

your actions according to what others think of you. Instead, a Daoist seeks a oneness with the

rhythms of nature, which probably requires walking away from society itself. Deliberately, Daoism

does not provide a set of rules and rituals because central to Daoist philosophy is the idea that

ritual does not cultivate virtue. Instead, Daoism provides guidelines on cultivating the virtues of

selflessness, moderation, detachment, and humility. Accordingly, Daoist philosophers did not publish

books detailing ritual practices like Confucians did. Instead, Daoists created poetry and stories that

show Daoist sages teaching about and exemplifying these virtues.

There are two main objections to virtue ethics as an ethical system: its vagueness and its relativism.

First, virtue ethics is too vague and subjective, and does not produce explicit rules for moral conduct

that can tell us how to act in specific circumstances. When facing ethical dilemmas, we feel better

if we have a clear answer about what to do. Virtue ethics offers general ideals rather than definitive

commands. We can create laws based on a definitive ethic against stealing, but we cannot make laws

saying “be wise” or “be patient.” Also problematic is that virtue ethics tends to hold that its virtues

apply variably according to the situation. It is far easier to practice the principles of never lying or

always being generous. Virtue ethics says there are times when lying is a better course of action and

being generous is a worse course of action, and this variability creates uncertainty. What is more, how

can I decide when the virtue applies and when it should not? Telling me to be wise and reflect on

the ethical virtues and the situation is offering more vagueness. Finally, we want to be able to rely on

other people’s behavior, and those who practice virtue ethics may vary in their behavior, so we may

not know exactly where we stand with them.

To consider this objection, we need to think about the nature of ethics itself. Yes, we could say

definitively, “You should not lie” and “you should not steal.” But what are those prohibitions based on?

A virtue ethicist could respond by arguing that both are based on the ethical principle of honesty and

that if that is so, then cultivating the virtue of honesty will lead one not to lie or steal from others. A

virtue ethicist would also say that virtue ethics focuses on the foundation of ethical life encapsulated

in objective reason (Aristotle), God’s natural law (Thomas), the law of karma (Buddhism), or the Dao

(Confucianism or Daoism), and therefore virtue is not entirely variable. Virtue ethics provides us with

the tools to make ethical decisions in the varying circumstances of our daily lives. The variability in

the behavior of those who practice virtue ethics reflects the variability of everyday life.

Second, there are different cultural definitions of human flourishing and virtue. All human cultures

have ethical values, but values vary across cultures. So how can we decide which set of virtues is right?

Even within a culture, two people will have different views about what the virtues are, and when and

ETHICS 35

how they apply. Because virtue ethics gives us no specific commands for how to act, each person is left

to himself or herself to decide how to act. Virtue ethics is too relative to be a helpful ethical theory.

Ethical relativism is a concern. If ethics means anything, it has to have some objective basis and cannot

be left entirely up to arbitrary whim. Virtue ethicists are aware of this danger and would respond

to it that virtue ethics is based on objective realities of the world and human nature. The virtues are

manifestations of how things are, or should be, outside of cultural or individual subjectivity. Different

cultures differ on how ethical virtues should be applied, but every culture values fundamental virtues

such as honesty, benevolence, courage, and justice. Differences in how cultures apply virtues may

reflect objective differences in their circumstances. When we interact with another culture, those

differences do need to be dealt with, but saying our culture is completely right and the other culture

wrong is not a helpful approach. Individuals similarly face the burden of needing to determine how

best to apply the virtues, and needing to deal with conflicts with others over how they think is best to

apply the virtues. But is this not similar to the decisions we have to make in all aspects of our lives?

An egoist is known for their big ego. They are self-centered and care little about others. If you google

the phrase “egoist,” almost all web pages that pop up teach you how to deal with them if you are so

unfortunate as to encounter one. Given such negative connotations, it might surprise you to learn that

some philosophers who are called “ethical egoists” argue that to act morally is to maximize one’s self-

interest. At least on the surface, being ethical is not all about seeking self-interest. Morality requires

us, for example, to keep promises, to treat others fairly, and to benefit those in need. It demands that

we act not in our self-interest even if we can get advantages by breaking promises, treating others

unfairly, or not helping the needy. Why then should we follow ethical norms that restrict our choices?

What exactly is the relationship between ethics and self-interest?

This last question is the central question that we will focus on in this chapter. We will see how three

different views, known as psychological egoism, ethical egoism, and social contract theory, address

this question. Before we dive into details about each theory, here is a rough picture: Psychological

egoism claims that true altruistic behavior is nothing more than wishful thinking because everything

we do is by definition self-serving. Ethical egoism goes a step further, arguing that even if we could be

unselfish, we can ignore any demand that ethics makes on us because we should put ourselves first.

Finally, social contract theory claims that ethics itself is rooted in self-interest, that is, that we should

really take others into account but only, ultimately, because doing so is in accord with what we want

and need for ourselves.

P S YC H O LO G I C A L E G O I S M

Psychological egoists argue that everything we do is self-serving even if we might think it is not. Self-

sacrificial behaviors, such as using oneself as a human shield to protect others in a mass shooting,

cannot disprove psychological egoism, because people who sacrifice themselves are not motivated by

altruistic concern. Rather, they simply do what they most want to do. Sacrificing one’s life happens to

be what one most wanted to do in those circumstances. Given that doing what one most wants to do

is in one’s self-interest, one’s “self-sacrificing” behavior is again egoistic. Altruism is nothing but an

illusion.

ETHICS 37

However, if doing what I am motivated to do is always self-serving, then trivially there is a sense

in which all my actions are self-serving. To avoid this charge, an egoist needs to avoid interpreting

psychological egoism as saying that, whatever the action one intends to do, it is always self-serving by

definition. Perhaps a better strategy for a psychological egoist is to emphasize one does an action X

always in order to further one’s self-interest. We act only for the sake of promoting our own best interest.

Many philosophers agree that the ultimate goal of one’s action is to further one’s best interest; what

they disagree on is how to understand the idea of “one’s best interest.” Aristotle (384-322 BCE), for

example, argues that eudaimonia (his term for the “happiness” that arises from a completely fulfilled

life) is a rational agent’s ultimate goal. Stoics, on the other hand, argue for virtuous or excellent

activities without pleasure. Still others, like Baruch Spinoza (1632-1677), argue that the ultimate goal

of one’s actions is to realize oneself or develop oneself. To make this idea appealing, an egoist must

flesh out the idea of self-realization or self-development, which in turn involves specifying what is

ideal to pursue.

Max Stirner (1806-1856) proposes that the ultimate goal of one’s action is self-governance and to

achieve it one need not take others’ interests into consideration. 1 To Stirner, “I” is absolute: “For me,

you are nothing but—my food, even as I too am fed upon and turned to use by you. We have only one

relation to each other, that of usableness, of utility, of use. We owe each other nothing, for what I seem

to owe you I owe at most to myself” (Stirner [1844] 1995, 263). If you accept the psychological egoist

view that one’s ultimate goal is always one’s own self-interest, Stirner’s picture of human interaction

may not surprise you. Any moral obligation to others is subject to one’s own self-interest. As he puts

it, “one must break faith, yes, even his oath, in order to determine himself instead of being determined

by moral considerations” (210). Acting for the sake of another person’s interest is impossible.

One of the chief objections to psychological egoism is that it is an example of a non-falsifiable theory.

It is very unlikely that one can know for certain how much one’s own motivation is of egoistic

concern or of altruistic concern. This difficulty has to do with the fact that one can hardly know

for sure about one’s own deep-down motivation. It can work in both ways. On the one hand, it

gives psychological egoists an opportunity to argue that even a person who emphasizes that she

does charity for an altruistic reason might, deep down, deceive herself. On the other hand, precisely

because it is difficult to be certain about one’s own deep-down motivation, psychological egoists’

assumption that deep down we are all self-serving seems unwarranted. A recent empirical study even

challenges the dichotomy between egoism and altruism by showing that people who are capable of

expressing extreme altruism are labeled high in narcissism (White, Szabo, and Tiliopoulos 2018).

Here are the key take-away points: psychological egoists attempt to persuade us that we can never be

truly altruistic and hence a truly realistic account of human behavior would have no place for anything

remotely resembling ethics, if “ethics” requires us, at least sometimes, not to pursue our own self

interest. But given that we hardly can know for sure our own deep-down motivation, we might still

be altruistic. Ethical egoism, on the other hand, argues that even if we can, we should not be altruistic.

1. Whether Max Stirner is a psychological egoist is disputed. David Leopold, for example, argues that he is not. (For Leopold’s

argument, see Stirner 1995, xxiv–xxv).

38 EGOISM AND SOCIAL CONTRACT THEORY

E T H I C A L E G O I S M

While psychological egoism claims that the ultimate goal of one’s action is one’s own self-interest,

ethical egoism claims that one should pursue one’s own best interest. The basic idea of ethical egoism is

this: promoting one’s own best interest is in accord with morality. In its strongest form, ethical egoism

claims that one acts morally if and only if one promotes one’s own best interest. In this section, we

will discuss and evaluate Adam Smith’s and Ayn Rand’s ethical egoistic claims. We will end up with

learning the biggest problem with ethical egoism, which serves as a transition to our next topic: the

social contract theory.

Adam Smith (1723-1790) famously argues for egoism as a practical ideal in economics: Each

businessperson promoting their best interest would most effectively promote the common good,

given that the “invisible hand” (i.e. free market) would coordinate individual economic activities. In

other words, if both buyers and sellers pursue nothing but the best deal for themselves, a win-win

situation will ensue. Another daily-life example of how ethical egoism brings out the socially optimal

outcome is competitive sports. The fact that each team is out to win produces the optimal outcome:

if the players played without keeping score, or if the weaker team reaped the same rewards, the game

would be boring to watch and the players would not reach their full potential. In other words, only

when every player promotes their best interest (i.e. playing to win) would the best outcome ensue (i.e.

we will enjoy watching the game and the players will reach their potential).

According to Smith, the successful function of the invisible hand depends on laissez-faire capitalism.

He bases his analysis of social institutions and behavior upon principles of human action, the starting

point of which is a form of ethical egoism:

Every man is, no doubt, by nature, first and principally recommended to his own care; and as he is fitter to

take care of himself than of any other person, it is fit and right that it should be so. (Smith [1759] 1976, 82)

Although he believes that one should first pursue one’s own best interest, Smith does not advocate

being a selfish, cold-blooded person. Instead, he argues that mutual kindness is necessary for

happiness (Smith [1759] 1976, 225). Starting from our natural drive of trying to share others’ feelings

as closely as possible, we adjust our feelings to the feelings of people we are concerned with and

in this process we eventually develop virtues (110-133, 135-136). Of two principal virtues, justice

and beneficence, the exercise of beneficence “deserves highest reward” (81). Here is a rough picture:

Given our natural drives and our social condition, we are on the path of developing virtues, the most

important of which is beneficence. Yet given that mutual kindness is necessary for happiness, we can

say that practicing kindness is necessary for one’s own best interest. In benefiting another person, one

is still pursuing one’s own self-interest. 2

Ayn Rand (1905-1982), who also argues for ethical egoism and laissez-faire capitalism, however,

argues that selfishness is a virtue. Altruism, which demands self-sacrifice, is even immoral. According

to her, life is the ultimate value, and hence “no society can be of value to man’s life if the price is

2. We should note that Smith is not a thoroughgoing egoist who argues that morality is founded upon self-interest. According to

Smith, moral rules stipulate what is fit and proper to be done or to be avoided and these rules are not dictated by self-love (159). It is

the “impartial spectator,” not self-love, that shows us “the propriety of resigning the greatest interests of our own, for the yet greater

interests of others” (137).

ETHICS 39

the surrender of his right to his life” (Rand 1964, 32). Concerned for the survival of civilization,

she condemns altruism for being responsible for destroying the civilized world. Altruism is also

responsible for making totalitarian regimes such as Nazi Germany and Soviet Russia possible, given

that altruism holds

death as its ultimate goal and standard of value—and it is logical that renunciation, resignation, self-denial,

and every other form of suffering, including self-destruction, are the virtues it advocates. (Rand 1964, 34-35)

Given that humans are rational beings, and that life is the ultimate value, “rational selfishness” is what

one should pursue (25-31). To act rationally is to put one’s own interest first. According to Rand, not

only is promoting one’s own best interest rational, it is also morally correct.

Without the burden of proving empirically that everyone must always act out of self-interest, ethical

egoism is more appealing than psychological egoism. However, the biggest challenge to ethical egoism

is that it lacks authoritative regulation of interpersonal conflicts of interest. Let me use an example to

illustrate this point. Suppose my grandfather indicated in his will that I am his sole heir and suppose

also that he is not bothered by any severe sickness. Suppose my cousin has been working her way to

replace me as the sole heir and suppose that I am in a bad situation which requires a lot of money that I

don’t have. Can it be morally wrong for me to kill my grandfather to ensure that I get the money now?

Ethical egoism cannot answer this question, because from my perspective it would not be morally

wrong but from my grandfather’s perspective it would be, and there’s no way to adjudicate between

these perspectives.

Someone might also argue that ethical egoism borders on being incoherent. If what ethical egoism

advocates is that everyone should do what is in their best interest, it seems confusing, if not outright

inconsistent, that ethical egoism argues that doing so is how we promote the social good (i.e., the good

that goes beyond the scope of self-interest). It seems self-contradictory to care about promoting social

good while caring only about promoting one’s own best interest. Whether this objection is damaging

to ethical egoism depends on whether promoting social good is fundamentally incompatible with

promoting one’s own best interest. Smith apparently thinks that they are not fundamentally

incompatible because he finds a way to incorporate the virtue of benevolence into his ethical egoism.

Whether he is successful in doing that (i.e. whether his assumption that we have a natural tendency to

care about others’ welfare fits well with ethical egoism) is another question. But the challenge seems

to apply to Rand. If, as Rand argues, one should promote one’s own good and altruism is immoral,

then it is confusing as to why she concerns herself with the issue of the survival of civilization (which

presumably promotes the common good).

The biggest problem for ethical egoism is that it fails to be a moral theory because it cannot deal

with interpersonal conflicts of interest. Only asking people to pursue their individual interests is not

enough. As countless examples show, we can all benefit much more from cooperation. The issue of

coordination is crucial given interpersonal conflicts of interest. Concern for coordination leads us to

the last topic of this chapter: social contract theory.

S O C I A L C O N T R AC T T H E O R Y

The basic idea of social contract theory in ethics is that ethical rules are sets of conventionally

40 EGOISM AND SOCIAL CONTRACT THEORY

established limits we impose on ourselves in keeping with our own longer-term interests. This

answers two fundamental questions about morality, namely, what is required and why we should

obey. What is morally required is what we, as rational and self-interested agents, do or would agree

upon. The reason why we should obey is because we have agreed, or would do so if we were being

fully rational. Social contract theory shares the core assumption of egoism that we are self-interested

and rational agents. However, realizing that living together in a society requires a set of rules for social

cooperation, social contract theory provides a justification for why we should coordinate with others.

Unlike egoism which cannot provide an impartial regulation of interpersonal conflicts of interest,

social contract theory not only provides a way to handle conflicts of interest but also provides a

justification for it. Given extra assumptions about human nature, we might end up following Thomas

Hobbes or John Rawls. But both agree that moral rules are essentially conventional and binding only

to the degree that we see them as serving our own interests.

If moral and social rules are conventional, what would life be like without such rules, and how would

this establish a motivation for defining and then following such rules? In particular, given that we

are self-interested, why would we agree to obey a set of rules that sometimes limit our own self-

ETHICS 41

interest? According to Thomas Hobbes (1588-1679), the pre-political natural state of humanity, which

he imagines as “the state of nature,” is a war of all against all in which people’s lives are “solitary,

poor, nasty, brutish, and short” (Hobbes [1651] 1996, 89). This miserable picture is derived from

the following empirical and normative assumptions: his empirical assumptions are that people are

sufficiently similar in their physical and mental faculties that no one is invulnerable and we all fear

death (86-87, 90). His normative assumptions are that each person in the state of nature has the liberty

to preserve their own lives and a right to do whatever in one’s opinion is necessary for survival;

he calls it “the right of nature.” There is no constraint on the right of nature; “every man has a

right to everything, even to one another’s body” (91). Given that resources are limited and we are

all vulnerable in the process of exerting our rights of nature, Hobbes paints the state of nature as

hell. Hobbes then envisions that we start to form social conventions based on mutual advantage. For

example, although in the state of nature there is nothing inherently wrong in harming you, I would

be better off by refraining to do so if everyone else does the same. A social convention against injury

is thus formed. Hobbes calls such a convention “a law of nature.” The fundamental law of nature is

“to seek peace, and follow it,” whereas the upshot of the entire set of laws of nature is “that law of

the Gospel: ‘whatsoever you require that others should do to you, that do ye to them’” (92). In short,

Hobbes’s social contract theory claims that moral requirements are nothing but social convention that

we as rational and self-interested agents agree upon for the sake of survival. Given that everyone’s life

is vulnerable in the state of nature, it is mutually advantageous to obey the social convention.

As a reader, you might wonder whether Hobbes’s story of the state of nature ever happened. But how

damaging is it to his moral theory if it turns out that in history people were never in the state of

nature? Some people adopt a hypothetical strategy, arguing that people would have agreed upon the

laws of nature were they in the state of nature. But a hypothetical agreement lacks the strength of a

real agreement. I cannot demand you to fulfill a hypothetical agreement that you financially support

me for the rest of my life, even if doing so would be in your best interest, because we did not actually

agree to this at a prior time. As far as I can see, the real problem is whether understanding moral

requirements as social conventions, the obeying of which is of mutual advantage, has enough force to

ensure that everyone does obey.

David Gauthier, a contemporary Hobbesian, argues that social conventions agreed upon as moral

requirements are derived from a bargaining process over mutually advantageous conventions. Given

that social conventions are derived from bargaining, people with the upper hand have little incentive

to produce a fair convention for the weak. After all, there is little to gain from cooperating with the

weak and little to fear of their retaliation. Even if a fair convention that takes care of the interests

of the weak is agreed upon, it does not guarantee that the strong will obey. After all, whether it is

advantageous to follow a particular convention also depends on one’s bargaining power. In Gauthier’s

theory, defenseless or people with disabilities “fall beyond the pale” of morality (Gauthier 1986, 268).

That is to say, moral constraints will only arise if people are roughly equal in power. Were I a person

with disabilities, I would be left out of moral consideration. This seems to push us back to a situation

close to Hobbes’s state of nature, a situation where the strong exploits the weak. If moral requirements

are all about the strong exploiting the weak, we don’t even need to call them “requirements” because

humans easily, if not naturally, act that way.

42 EGOISM AND SOCIAL CONTRACT THEORY

Another contemporary social contract theory—Kantian contractarianism—has an entirely different

outlook even though it shares the same assumption that we are rational and self-interested agents.

Kantian contractarianism bases the social contract on a natural equality of moral status which makes

each person’s interests a matter of impartial concern. It has roots in Immanuel Kant’s (1724-1807)

moral theory (see Chapter 6) which takes each person as “an end in itself,” an intrinsically valuable

moral status, and demands each person act in accord with universalizable personal policies (which

Kant calls “maxims”) as a member of the community (Kant [1785] 2002). Following Kant’s idea that

our equal status (as an end in itself) demands us to act in an impartial way in a community, John Rawls

(1921-2002) develops a social contract theory that answers the question “What terms of cooperation

would free and equal citizens agree to under fair conditions?” Whereas Hobbes’s social contract is

based on the state of nature, Rawls’s is based on “the original position of equality” where people, as

free and equal beings, collectively figure out the social contract that they agree upon. To avoid the

strong having dominant bargaining power over the weak in the process as Gauthier paints it, Rawls

stipulates that people in the original position make the bargain under a “veil of ignorance,” that is,

people have no idea of their natural talents and their social position. Because people are not aware

of any natural or social differences between them, they are equal and more likely to act toward each

other in a non-biased, impartial way. Notice that Rawls’s idea of the “original position” does not refer

to any actual historical event. Rather, it is a device that helps us vividly imagine a fair and impartial

point of view, when we reason about fundamental principles of justice. To maximize one’s own best

interest in this condition, Rawls believes, people will come up with and endorse a fair contract in an

impartial way. If inequality is unavoidable, it must be justified to those made worse off, and perhaps

even subject to their veto. Hence, vulnerable people won’t be excluded from the domain of morality as

they will be in Gauthier’s picture. Rawls assumes that people will act benevolently if they are rational,

self-interested, and behind the veil of ignorance. Thus, the original position “represents equality

between human beings as moral persons” (Rawls 1971, 190).

C O N C L U S I O N

Although it is hard to prove that everyone must always act out of self-interest, it is probably true that

we have the tendency to act for the sake of promoting our own best interest. The starting point of

both egoism and social contract theory is that we are self-interested and rational beings. However,

basing morality on self-interest alone does not get us far and even defeats the idea of morality. Why

should we continue to follow moral rules in cases where following them would not in fact be in our

personal best interest? A social contract theory, be it Hobbes’s, Gauthier’s, or Rawls’s, can still suffer

from the prisoner’s dilemma where everyone rationally acts in a self-interested way even when doing

so is detrimental for the good of all involved. 3 For example, my roommate and I agree that it is best

3. How Jean Hampton criticized Hobbes can also apply to contemporary contractarianism. She doubts whether having a social

contract can indeed function as well as intended. Suppose the war of all against all is triggered by greed or fear; there is no

guarantee that a person who was greedy before the contract is drawn up will stop being greedy after the contract is drawn up.

Moreover, having a social contract seems to not guarantee that we can be entirely free of the prisoner’s dilemma. That is, given that

there is no guarantee that another person will keep their end of the bargain, it’s better for me not to keep my end of the bargain. No

matter how harsh a punishment we set up for a contract violator, there is always someone who is willing to take the risk. In short,

Hampton’s point is that whatever makes a person unable to cooperate before a contract is drawn up might not go away after a

contract is drawn up. A contractarian cannot guarantee that (Hampton, 1986). Gauthier’s response is that a contract can avoid the

problem if the contractors realize that they are in an environment of like-minded individuals (Gauthier 1986, 160-166). Whether

Gauthier’s response really solves the problem, however, is disputed (see Vallentyne 1991).

ETHICS 43

if everyone helps keep the place clean. Out of self-interest, it is rational for each of us to find some

excuse not to clean up. As a result, no one actually keeps the agreement and our place probably is a

mess. Moral requirements based on agreement thus still lack sufficient force to ensure that everyone

in fact does comply. Why should we follow norms that restrict our choices in certain cases? In the

previous chapters, we have seen that the authority of cultural norms, religious rules, and appeals to

nature do not conclusively show why it is that we should follow the rules. In this chapter, we have

seen that appealing to self-interest is also not sufficient to account for such rules. Instead, we need to

derive more objective ethical principles from reason. Rawls’s Kantian idea is a move toward objective

and impartial ethical principles. The following chapters explore other philosophers who base such

principles upon reason.

I N T RO D U C T I O N

Let us start our introduction to utilitarianism with an example that shows how utilitarians answer

the following question, “Can the ends justify the means?” Imagine that Peter is an unemployed poor

man in New York. Although he has no money, his family still depends on him; his unemployed wife

(Sandra) is sick and needs $500 for treatment, and their little children (Ann and Sam) have been

thrown out of school because they could not pay tuition fees ($500 for both of them). Peter has no

source of income and he cannot get a loan; even John (his friend and a millionaire) has refused to help

him. From his perspective, there are only two alternatives: either he pays by stealing or he does not.

So, he steals $1000 from John in order to pay for Sandra’s treatment and to pay the tuition fees of

Ann and Sam. One could say that stealing is morally wrong. Therefore, we will say that what Peter has

done— stealing from John—is morally wrong.

Utilitarianism, however, will say what Peter has done is morally right. For utilitarians, stealing in

itself is neither bad nor good; what makes it bad or good is the consequences it produces. In our

example, Peter stole from one person who has less need for the money, and spent the money on three

people who have more need for the money. Therefore, for utilitarians, Peter’s stealing from John (the

“means”) can be justified by the fact that the money was used for the treatment of Sandra and the

tuition fees of Ann and Sam (the “end”). This justification is based on the calculation that the benefits

of the theft outweigh the losses caused by the theft. Peter’s act of stealing is morally right because it

produced more good than bad. In other words, the action produced more pleasure or happiness than

pain or unhappiness, that is, it increased net utility.

The aim of this chapter is to explain why utilitarianism reaches such a conclusion as described above,

and then examine the strengths and weaknesses of utilitarianism. The discussion is divided into three

parts: the first part explains what utilitarianism is, the second discusses some varieties (or types) of

utilitarianism, and the third explores whether utilitarianism is persuasive and reasonable.

ETHICS 45

W H AT I S U T I L I TA R I A N I S M ?

Utilitarianism is a form of consequentialism. For consequentialism, the moral rightness or wrongness

of an act depends on the consequences it produces. On consequentialist grounds, actions and

inactions whose negative consequences outweigh the positive consequences will be deemed morally

wrong while actions and inactions whose positive consequences outweigh the negative consequences

will be deemed morally right. On utilitarian grounds, actions and inactions which benefit few people

and harm more people will be deemed morally wrong while actions and inactions which harm fewer

people and benefit more people will be deemed morally right.

Benefit and harm can be characterized in more than one

way; for classical utilitarians such as Jeremy Bentham

(1748-1832) and John Stuart Mill (1806-1873), they are

defined in terms of happiness/unhappiness and pleasure/

pain. On this view, actions and inactions that cause less

pain or unhappiness and more pleasure or happiness than

available alternative actions and inactions will be deemed

morally right, while actions and inactions that cause more

pain or unhappiness and less pleasure or happiness than

available alternative actions and inactions will be deemed

morally wrong. Although pleasure and happiness can have

different meanings, in the context of this chapter they will

be treated as synonymous.

Utilitarians’ concern is how to increase net utility. Their

moral theory is based on the principle of utility which

states that “the morally right action is the action that

produces the most good” (Driver 2014). The morally

wrong action is the one that leads to the reduction of the

maximum good. For instance, a utilitarian may argue that

although some armed robbers robbed a bank in a heist, as

long as there are more people who benefit from the robbery (say, in a Robin Hood-like manner the

robbers generously shared the money with many people) than there are people who suffer from the

robbery (say, only the billionaire who owns the bank will bear the cost of the loss), the heist will be

morally right rather than morally wrong. And on this utilitarian premise, if more people suffer from

the heist while fewer people benefit from it, the heist will be morally wrong.

From the above description of utilitarianism, it is noticeable that utilitarianism is opposed to

deontology, which is a moral theory that says that as moral agents we have certain duties or

obligations, and these duties or obligations are formalized in terms of rules (see Chapter 6). There

is a variant of utilitarianism, namely rule utilitarianism, that provides rules for evaluating the utility

of actions and inactions (see the next part of the chapter for a detailed explanation). The difference

between a utilitarian rule and a deontological rule is that according to rule utilitarians, acting

according to the rule is correct because the rule is one that, if widely accepted and followed, will

produce the most good. According to deontologists, whether the consequences of our actions are

46 UTILITARIANISM

positive or negative does not determine their moral rightness or moral wrongness. What determines

their moral rightness or moral wrongness is whether we act or fail to act in accordance with our duty

or duties (where our duty is based on rules that are not themselves justified by the consequences of

their being widely accepted and followed).

S O M E VA R I E T I E S (O R T Y P E S ) O F U T I L I TA R I A N I S M

The above description of utilitarianism is general. We can, however, distinguish between different

types of utilitarianism. First, we can distinguish between “actual consequence utilitarians” and

“foreseeable consequence utilitarians.” The former base the evaluation of the moral rightness and

moral wrongness of actions on the actual consequences of actions; while the latter base the evaluation

of the moral rightness and moral wrongness of actions on the foreseeable consequences of actions.

J. J. C. Smart (1920-2012) explains the rationale for this distinction with reference to the following

example: imagine that you rescued someone from drowning. You were acting in good faith to save

a drowning person, but it just so happens that the person later became a mass murderer. Since the

person became a mass murderer, actual consequence utilitarians would argue that in hindsight the

act of rescuing the person was morally wrong. However, foreseeable consequence utilitarians would

argue that—looking forward (i.e., in foresight)—it could not be foreseen that the person was going to

be a mass murderer, hence the act of rescuing them was morally right (Smart 1973, 49). Moreover,

they could have turned out to be a “saint” or Nelson Mandela or Martin Luther King Jr., in which case

the action would be considered to be morally right by actual consequence utilitarians.

A second distinction we can make is that between act utilitarianism and rule utilitarianism. Act

utilitarianism focuses on individual actions and says that we should apply the principle of utility

in order to evaluate them. Therefore, act utilitarians argue that among possible actions, the action

that produces the most utility would the morally right action. But this may seem impossible to do

in practice since, for every thing that we might do that has a potential effect on other people, we

would thus be morally required to examine its consequences and pick the one with the best outcome.

Rule utilitarianism responds to this problem by focusing on general types of actions and determining

whether they typically lead to good or bad results. This, for them is the meaning of commonly

held moral rules: they are generalizations of the typical consequences of our actions. For example,

if stealing typically leads to bad consequences, stealing in general would be considered by a rule

utilitarian to be wrong. 1

Hence rule utilitarians claim to be able to reinterpret talk of rights, justice, and fair treatment in terms

of the principle of utility by claiming that the rationale behind any such rules is really that these rules

generally lead to greater welfare for all concerned. We may wonder whether utilitarianism in general

is capable of even addressing the notion that people have rights and deserve to be treated justly and

fairly, because in critical situations the rights and wellbeing of persons can be sacrificed as long as this

seems to lead to an increase overall utility.

1. Of course, there may be exceptions to such a rule in particular, atypical cases if stealing might lead to better consequences. This

raises a complication for rule utilitarians: if they were to argue that we should follow rules such as “do not steal” except in those

cases where stealing would lead to better consequences, then this could mean rule utilitarianism wouldn’t be very different from act

utilitarianism. One would still have to evaluate the consequences of each particular act to see if one should follow the rule or not.

Hooker (2016) argues that rule utilitarianism need not collapse into act utilitarianism in this way, because it would be better to have

a set of rules that are more clear and easily understood and followed than ones that require us to evaluate many possible exceptions.

ETHICS 47

For example, in a version of the famous “trolley

problem,” imagine that you and an overweight

stranger are standing next to each other on a

footbridge above a rail track. You discover that

there is a runaway trolley rolling down the track

and the trolley is about to kill five people who

cannot get off of the track quickly enough to

avoid the accident. Being willing to sacrifice

yourself to save the five persons, you consider

jumping off the bridge, in front of the trolley…but

you realize that you are far too light to stop the

trolley….The only way you can stop the trolley

killing five people is by pushing this large stranger

off the footbridge, in front of the trolley. If you push

the stranger off, he will be killed, but you will save the other five. (Singer 2005, 340)

Utilitarianism, especially act utilitarianism, seems to suggest that the life of the overweight stranger

should be sacrificed regardless of any purported right to life he may have. A rule utilitarian, however,

may respond that since in general killing innocent people to save others is not what typically leads

to the best outcomes, we should be very wary of making a decision to do so in this case. This is

especially true in this scenario since everything rests on our calculation of what might possibly stop

the trolley, while in fact there is really far too much uncertainty in the outcome to warrant such a

serious decision. If nothing else, the emphasis placed on general principles by rule utilitarians can

serve as a warning not to take too lightly the notion that the ends might justify the means.

Whether or not this response is adequate is something that has been extensively debated with

reference to this famous example as well as countless variations. This brings us to our final question

here about utilitarianism—whether it is ultimately a persuasive and reasonable approach to morality.

I S U T I L I TA R I A N I S M P E R S UA S I V E A N D R E A S O N A B L E ?

First of all, let us start by asking about the principle of utility as the foundational principle of morality,

that is, about the claim that what is morally right is just what leads to the better outcome. John Stuart

Mill’s argument that it is is based on his claim that “each person, so far as he believes it to be attainable,

desires his own happiness” (Mill [1861] 1879, Ch. 4). Mill derives the principle of utility from this

claim based on three considerations, namely desirability, exhaustiveness, and impartiality. That is,

happiness is desirable as an end in itself; it is the only thing that is so desirable (exhaustiveness); and

no one person’s happiness is really any more desirable or less desirable than that of any other person

(impartiality) (see Macleod 2017).

In defending desirability, Mill argues,

The only proof capable of being given that an object is visible, is that people actually see it. The only

proof that a sound is audible, is that people hear it: and so of the other sources of our experience. In like

manner…the sole evidence it is possible to produce that anything is desirable, is that people do actually desire

it. (Mill [1861] 1879, Ch. 4)

48 UTILITARIANISM

In defending exhaustiveness, Mill does not argue that other things, apart from happiness, are not

desired as such; but while other things appear to be desired, happiness is the only thing that is really

desired since whatever else we may desire, we do so because attaining that thing would make us

happy. Finally, in defending impartiality, Mill argues that equal amounts of happiness are equally

desirable, whether the happiness is felt by the same person or by different persons. In Mill’s words,

“each person’s happiness is a good to that person, and the general happiness, therefore, a good to

the aggregate of all persons” (Mill [1861] 1879, Ch. 4). We may wonder, however, whether this last

argument is truly adequate. Does Mill really show here that we should treat everyone’s happiness as

equally worthy of pursuit, or does he simply assert this?

Let us grant that Mill’s argument here is successful and the principle of utility is the basis of morality.

Utilitarianism claims that we should thus calculate, to the best of our ability, the expected utility that

will result from our actions and how it will affect us and others, and use that as the basis for the

moral evaluation of our decisions. But then we may ask, how exactly do we quantify utility? Here

there are two different but related problems: how can I come up with a way of comparing different

types of pleasure and pain, benefit or harm that I myself might experience, and how can I compare my

benefit and yours on some neutral scale of comparison? Bentham famously claimed that there was a

single universal scale that could enable us to objectively compare all benefits and harms based on the

following factors: intensity, duration, certainty/uncertainty, proximity, fecundity, purity, and extent.

And he offered on this basis what he called a “felicific calculus” as a way of objectively comparing any

two pleasures we might encounter (Bentham [1789] 1907).

For example, let us compare the pleasure of drinking a pint of beer to that of reading Shakespeare’s

Hamlet. Suppose the following are the case:

• The pleasure derived from drinking a pint of beer is more intense than the pleasure derived

from reading Hamlet (intensity).

• The pleasure of drinking the beer lasts longer than that of reading Hamlet (duration).

• We are confident that drinking the beer is more pleasurable than reading Hamlet (certainty/

uncertainty).

• The beer is closer to us than the play, and therefore it is easier for us to access the former than

the latter (proximity).

• Drinking the beer is more likely to promote more pleasure in the future while reading Hamlet

is less likely to promote more pleasure in the future (fecundity).

• Drinking the beer is pure pleasure while reading Hamlet is mixed with something else (purity).

• Finally, drinking the beer affects both myself and my friends in the bar and so has a greater

extent than my solitary reading of Hamlet (extent).

Since, on all of these measures, drinking a pint of beer is more pleasurable than reading Hamlet,

it follows according to Bentham that it is objectively better for you to drink the pint of beer and

forget about reading Hamlet, and so you should. Of course, it is up to each individual to make such a

calculation based on the intensity, duration, certainty, etc. of the pleasure resulting from each possible

choice they may make in their eyes, but Bentham at least claims that such a comparison is possible.

ETHICS 49

This brings us back to the problem we mentioned before that, realistically, we cannot be expected

to always engage in very difficult calculations every single time we want to make a decision. In an

attempt to resolve this problem, utilitarians might claim that in the evaluation of the moral rightness

and moral wrongness of actions, the application of the principle of utility can be backward-looking

(based on hindsight) or forward-looking (based on foresight). That is, we can use past experience of

the results of our actions as a guide to estimating what the probable outcomes of our actions might

be and save ourselves from the burden of having to make new estimates for each and every choice we

may face.

In addition, we may wonder whether Bentham’s approach misses something important about the

different kinds of pleasurable outcomes we may pursue. Mill, for example, would respond to our

claim that drinking beer is objectively more pleasurable than reading Hamlet by saying that it

overlooks an important distinction between qualitatively different kinds of pleasure. In Mill’s view

Bentham’s calculus misses the fact that not all pleasures are equal—there are “higher” and “lower”

pleasures that make it “better to be a human being dissatisfied than a pig satisfied; better to be Socrates

dissatisfied than a fool satisfied” (Mill [1861] 1879, Ch. 2). Mill justifies this claim by saying that

between two pleasures, although one pleasure requires a greater amount of difficulty to attain than

the other pleasure, if those who are competently acquainted with both pleasures prefer (or value) one

over the other, then the one is a higher pleasure while the other is a lower pleasure. For Mill, although

drinking a pint of beer may seem to be more pleasurable than reading Hamlet, if you are presented

with these two options and you are to make a choice—each and every time or as a rule—you should

still choose to read Hamlet and forego drinking the pint of beer. Reading Hamlet generates a higher

quality (although perhaps a lower quantity) of pleasure, while drinking a pint of beer generates lower

quality (although higher quantity) of pleasure.

In the end, these issues may be merely technical problems faced by utilitarianism—is there some

neutral scale of comparison between pleasures? If there is, is it based on Betham’s scale which makes

no distinctions between higher and lower pleasures, or Mill’s which does? The more serious problem,

however, remains, which is that utilitarianism seems willing in principle to sacrifice the interests and

even perhaps lives of individuals for the sake of the benefit of a larger group. And this seems to conflict

with our basic moral intuition that people have a right not to be used in this way. While Mill argued

that the notion of rights could be accounted for on purely utilitarian terms, Bentham simply dismissed

it. For him such “natural rights” are “simple nonsense, natural and imprescriptible rights, rhetorical

nonsense—nonsense upon stilts” (Bentham [1796] 1843, 501).

C O N C L U S I O N

Let us conclude by revisiting the question we started with: can the ends justify the means? I stated

that as far as utilitarianism is concerned the answer to this question is in the affirmative. While the

answer is plausible and right for utilitarians, it is implausible for many others, and notably wrong for

deontologists. As we have seen in this chapter, on a close examination utilitarianism is less persuasive

and less reasonable than it appears to be when it is far away.

Immanuel Kant (1724-1804) by Johann Gottlieb Becker via Wikimedia Commons. This work is in the public domain.

C H A P T E R 6 .

K A N T I A N D E O N TO LO G Y

J O S E P H K R A N A K

Relative to most other philosophers, Immanuel Kant

(1724-1804) was a late bloomer, publishing his first

significant work, The Critique of Pure Reason, in 1781 at

age 57. But this didn’t slow him down, as through his 50s,

60s, and 70s, he published numerous large and influential

works in many areas of philosophy, including ethics. He

published two large works on ethics, The Critique of

Practical Reason and The Metaphysics of Morals, but it’s his

first short work of ethics, Groundwork of the Metaphysics of

Morals that is his most important because it provides a

succinct and relatively readable account of his ethics.

Some of the main questions that Kant’s ethics focuses on

are questions of right and wrong: What makes an action

right or wrong? Which actions are we required by

morality to perform? Do consequences matter? Is it ever

permissible to do something morally wrong in order to

achieve good consequences? Is it important to do actions

with good intentions? And what are good intentions?

Some of Kant’s answers to some of these questions are

complex, but as we will see, he doesn’t think that

consequences matter and thus good consequences cannot

justify wrong actions. He also thinks that intentions are important to the ethical evaluation of actions.

D E O N TO LO G Y

One of the distinctive features of Kant’s ethics is that it focuses on duties, defined by right and

wrong. Right and wrong (which are the primary deontic categories, along with obligatory, optional,

supererogatory, and others) are distinct from good and bad (which are value categories) in that

52 ETHICS

they directly prescribe actions: right actions are ones we ought to do (are morally required to do)

and wrong actions we ought not to do (are morally forbidden from doing). This style of ethics is

referred to as deontology. The name comes from the Greek word deon, meaning duty or obligation. In

deontology, the deontic categories are primary, while value determinations are derived from them. As

we’ll see, Kant believes all our duties can be derived from the categorical imperative. We’ll first need

to explain what Kant means by the phrase “categorical imperative” and then we’ll look at the content

of this rule.

First, Kant believes that morality must be rational. He models his morality on science, which seeks to

discover universal laws that govern the natural world. Similarly, morality will be a system of universal

rules that govern action. In Kant’s view, as we will see, right action is ultimately a rational action. As an

ethics of duty, Kant believes that ethics consists of commands about what we ought to do. The word

“imperative” in his categorical imperative means a command or order. However, unlike most other

commands, which usually come from some authority, these commands come from within, from our

own reason. Still, they function the same way: they are commands to do certain actions.

Kant distinguishes two types of imperatives: hypothetical and categorical imperatives. A hypothetical

imperative is a contingent command. It’s conditional on a person’s wants, needs, or desires and

normally comes in the following form: “If you want/need A, then you ought to do B.” For example,

the advice, “If you want to do well on a test, then you should study a lot” would be a hypothetical

imperative. The command that you study is contingent on your desire to do well on the test. Other

examples are, “If you are thirsty, drink water,” or “If you want to be in better shape, you should

exercise.” Such commands are more like advice on how to accomplish our goals than moral rules. If

you don’t have a particular want, desire, or goal, then a hypothetical imperative doesn’t apply. For

example, if you don’t want to be in better shape, then the hypothetical imperative that you should

exercise, doesn’t apply to you.

A genuinely moral imperative would not be contingent on wants, desires, or needs, and this is what

is meant by a categorical imperative. A categorical imperative, instead of taking an if-then form, is

an absolute command, such as, “Do A,” or “You ought to do A.” Examples of categorical imperatives

would be “You shouldn’t kill,” “You ought to help those in need,” or “Don’t steal.” It doesn’t matter what

your wants or goals are; you should follow a categorical imperative no matter what.

But these aren’t the categorical imperative. Kant believes that there is one categorical imperative that is

the most important and that should guide all of our actions. This is the ultimate categorical imperative

from which all other moral rules are derived. This categorical imperative can be expressed in several

different ways, and Kant presents three formulations of it in The Groundwork.

T H E F I R S T F O R M U L AT I O N O F T H E C AT E G O R I C A L I M P E R AT I V E

The underlying idea behind the first formulation of the categorical imperative is that moral rules are

supposed to be universal laws. If we think of comparable laws, such as scientific laws like the law of

gravitational attraction or Newton’s three laws of motion, they are universal and apply to all people

equally, no matter who they are or what their needs are. If our moral rules are to be rational, then they

should have the same form.

ETHICS 53

From this idea, Kant derives his first formulation of the categorical imperative, “act only in

accordance with that maxim through which you can at the same time will that it become a universal

law” (Groundwork 4:421). 1

First, we must explain this word “maxim.” What Kant means by a maxim is a personal rule or a general

principle that underlies a particular action. As rational beings, we don’t just act randomly; we devise

certain rules that tell us what to do in different circumstances. A complete maxim will include three

pieces: the action, the circumstances under which we do that action, and the purpose behind that

action. For example, the maxim explaining why you’re reading this book, if it’s an assigned text, might

be, “I will read all books assigned for class because I want to succeed in class.” Different principles

could underlie the same action. For example, you might be reading this book simply to help you

understand the topic, in which case your principle might be, “When I am confused about a topic, I will

read an accessible text to improve my understanding.” The important point is that we are guided by

general principles that we give to ourselves, that tell us what we’ll do in certain circumstances.

The first formulation, thus, is a test of whether any particular maxim should be followed or not. We

test a maxim by universalizing it, that is, by asking if it would be possible for everyone to live by this

maxim. If the maxim can be universalized, meaning that it’s possible that everyone could live by it,

then it’s permissible to follow it. If it can’t be universalized, then it is impermissible to follow it. The

logic of the universalization test is that any rule you follow should apply to everyone—there’s nothing

special about you that allows you to be an exception.

To look at some examples, imagine you need money to pay off some debts. You go to a friend to

borrow the money and tell this friend that you will pay him back. You know you won’t be able

to pay your friend back, but you promise him nonetheless. You are making a false promise. Is this

permissible? To test, we first look at the maxim underlying the action, something like, “If I need

something, I’ll make a false promise in order to get what I need.” What would happen if everyone

were to make false promises every time they needed something? False promises would be rampant, so

rampant that promises would become meaningless; they would just be empty words. For this reason,

the maxim can’t be universalized. The maxim included the idea of making a promise, but if, when

universalized, promises cease to have any meaning, then we couldn’t really make a promise. Since the

maxim can’t be universalized, we shouldn’t follow it, and thus we derive the duty to not make false

promises.

We should note that Kant’s universalization test is not asking whether universalizing a maxim would

lead to undesirable consequences. Kant is not claiming that making a false promise is wrong because

we wouldn’t want to live in a world where no one kept their promises. It’s wrong because it’s not

possible to universalize the maxim. It’s not possible because it leads to a contradiction. In this case,

the contradiction is in the concept of a promise: that it becomes meaningless when universalized. We

can see this with other maxims. If you’re thinking of stealing something, the maxim underlying this

1. There are many different editions and translations of Kant’s works, and it is common practice in the philosophical community to

use a standard referencing system that is the same across all of these rather than using page numbers (which differ across the various

editions). The standard system, used in this chapter as well, refers to the German Royal Academy of Sciences edition of Kant’s

works, Kant’s Gesammelte Schriften. Most editions of Kant’s texts will have the Academy reference numbers in them to make it easy

to find quotes and arguments across editions.

54 KANTIAN DEONTOLOGY

action might be something like, “I’ll steal the things I want so I can have what I want.” If everyone were

to follow this maxim, then the concept of ownership would cease to have any meaning, and if nothing

were owned, then how would it be possible to steal? To steal means to take someone else’s property

without permission, and this is where the contradiction comes in. It’s not possible to steal if nothing

belongs to anyone. Thus, it’s not possible to universalize this maxim, and we thereby get the duty that

we shouldn’t steal. Both of these contradictions are what Kant calls “contradictions in conception.”

Another example Kant gives is of our obligation to help out others. Suppose you could help people

but didn’t want to. Your maxim might be, “I will never help out anyone else since everyone should

be independent.” If this were universalized, then everyone would be completely independent, with

no one asking for, nor offering help. However, we wouldn’t be able to live in a world where no one

helps anyone because we’ll inevitably sometimes need others’ help. The contradiction in this case is

a practical contradiction, “a contradiction in will,” as Kant calls it. In this case, we would eventually

have to break the maxim due to our need for help. Thus, from this, we get the duty that we should

sometimes help out others in need.

P RO B L E M S W I T H T H E F I R S T F O R M U L AT I O N

One criticism that Kant faced among his contemporaries was for his stance on lying, since he said

that we always have a duty to be truthful to others (Metaphysics of Morals 8:426). His reasoning seems

to be that if we were to try to universalize a maxim that permits lying, such as “I will lie whenever

it’s convenient to get what I want,” then people would be lying constantly, and it would lead to the

concepts of “lie” and “truth” becoming meaningless. Thus, since “lie” would no longer mean anything,

it’s impossible to universalize this maxim, and thus we should never lie. His contemporaries thought

there must be cases where lying is permissible, and Kant responded in “On a Supposed Right to Lie

From Philanthropy.” In this essay, Kant imagined a situation that would seem to permit lying. Suppose

that your friend is being pursued by someone who intends to kill him. Your friend comes to your

house and asks to hide. You let him do so, and soon after, the killer is knocking at your door asking,

“Is your friend inside?” Should you lie or not?

Kant asserts that you shouldn’t lie, even in these circumstances. Suppose your friend hears the killer

knocking at the door and decides to flee out the back without your knowing. You lie and tell the killer

that your friend is not here, and the killer leaves. Because of this, your friend and the killer bump into

each other, and your friend is killed. Since your lie led to them to bump into each other, you bear some

responsibility for the friend’s death. His general point is that consequences are uncertain. Importantly,

Kant believes that consequences don’t affect whether an action is right or wrong, and this example

highlights why: because consequences are unpredictable. The type of rational approach to ethics that

Kant prefers will downplay the importance of consequences due to this unpredictability.

Another problem for the first formulation is that it’s possible to imagine maxims that can’t be

universalized but that don’t seem to be immoral. For example, a stamp collector might live by the

maxim, “I will buy but not sell stamps in order to expand my collection.” If everyone were to follow

this, then the collector wouldn’t be able to buy because no one would be selling. This seems to lead to

the implausible conclusion that collecting stamps (or collecting anything) is immoral. Since Kant says

ETHICS 55

that we are to “act only in accordance” with maxims that can be universalized, then any maxim that

can’t be universalized is impermissible.

Some who want to defend Kant think that the problem is with how this maxim is phrased. The

maxim specifies two actions: buying and not selling. If we split it into two maxims—“I will buy stamps

to expand my collection” and “I will not sell stamps to expand my collection”—the problem can be

avoided. This does point to a general difficulty with the first formulation, generally referred to as the

“problem of relevant descriptions,” which is that there is often more than one way to describe the

maxim underlying an action. And when we formulate it some ways (like in this case with the stamp

collecting) it leads to a contradiction, whereas formulating it other ways does not.

G O O D W I L L

For Kant, just doing the right thing is not sufficient for making an action have full moral worth. It’s

also necessary to act with good will, by which Kant means something like the inclination to do good

or what is also known as a good character. He believes that a good will is essential for morality. This

is intuitively plausible because it seems that if an otherwise good action is done with bad or selfish

intentions, that can rob the action of its moral goodness. If we imagine a man who goes to work at a

soup kitchen to help out the poor, that seems like a good action. But if he’s going there just to impress

someone who works there, then that’s less virtuous. And if he’s going there to embezzle money from

the charity, the action would be morally wrong.

Less intuitive is that Kant thinks the only possible genuine good will is respect for the moral law.

Arthur Schopenhauer (1788-1860) would later describe Kant’s position as, “a deed must be performed

simply and solely out of regard for the known law and for the concept of duty…. It must not be

performed from any inclination, any benevolence felt towards others, any tender-hearted sympathy,

compassion, or emotion of the heart” ([1818] 1969, 526). That is, when you do something because it is

the right thing to do, that alone counts as good will.

56 KANTIAN DEONTOLOGY

Arthur Schopenhauer by Johann Schäffer via Wikimedia Commons. This work is in the public domain.

Schopenhauer was a critic of Kant’s philosophy, including

his ethics, and he objected that Kant’s view of the good will

is “directly opposed to the genuine spirit of virtue; not the

deed, but the willingness to do it, the love from which it

results, and without which it is a dead work, this constitutes

its meritorious element” ([1818] 1969, 526). Schopenhauer

thought that good people are good because they want to do

good actions and they feel love and compassion towards

others. If we return to the example of working in the soup

kitchen, if the person is showing up to the soup kitchen

because he likes helping people or he feels compassion for

the people he helps and wants to improve their lot,

Schopenhauer would say this is a good person and thus a

virtuous action.

Kant defended his position on good will by saying that an

action done out of love or out of compassion is not fully

autonomous. Autonomy means self-rule, and Kant saw it as

a necessary condition for freedom and morality. If an action

is not done autonomously, it is not really morally good or

bad. Again, if our friend at the soup kitchen is working there

because of some implant in his brain by which another

person is able to control his every action, then the action is neither autonomous nor morally

commendable.

Concerning acting out of love and compassion, Kant believed that when people act due to their

emotions, then their emotions are in control, not their rationality. To be truly autonomous, for Kant,

an action must be done because of reason. An action done because of emotion is not fully free and

not quite fully moral. This doesn’t mean you shouldn’t enjoy doing good things. It just means that this

shouldn’t be the reason underlying the action. According to Kant’s ethics, it’s morally commendable

for a person, acting out of good will, to decide that helping at the soup kitchen is the right thing to do,

to go there, and then to thoroughly enjoy doing so and feel great compassion for the people helped.

The important point is that reason you do an action should be because you have determined that it is

the right thing to do.

T H E S E C O N D F O R M U L AT I O N O F T H E C AT E G O R I C A L I M P E R AT I V E

The idea underlying the second formulation is that all humans are intrinsically valuable. As Kant

writes, “What has a price can be replaced by something else as its equivalent; what on the other hand

is raised above all price and therefore admits of no equivalent has a dignity” (Groundwork 4.434). What

has a price is a thing, but a person has dignity and is thus beyond price and irreplaceable. It follows

that a person with dignity deserves respect and shouldn’t be treated as a thing.

Kant expresses this idea in the second formulation of his categorical imperative: “So act that you use

ETHICS 57

humanity, whether in your own person or in the person of any other, always at the same time as an

end, never merely as a means” (Groundwork 4:429).

That is, we shouldn’t treat people merely as means to ends; we should treat them as ends, including

ourselves. To treat someone merely as a means is to not give the person the proper respect—to fail to

treat the person with dignity, to treat the person as a thing. It makes sense to use inanimate objects as

tools—you can use a hammer as a means to drive in nails without worrying about what the hammer

feels about this because it’s a thing. But if you use a person in such a way, it devalues the person.

Similarly, if you harm someone, take advantage of someone, or steal from someone, then you treat

that person as a thing, as a means to your ends. Conversely, if you treat someone as having unlimited

value, if you treat the person with dignity and respect, then you treat the person as an end.

One important thing to add is that Kant says we should never treat people “merely as a means.” The

“merely” is there to acknowledge that we can treat people as means, so long as we don’t only treat

them as means. It’s not unusual to have to use other people for their skills or knowledge, so it’s

necessary to sometimes treat people as means. For example, imagine that your pipes need fixing, and

you call a plumber. You’re using the plumber as a means because he is making your end (to fix your

pipes) his end, but there is nothing wrong with this if you also treat him as an end—that is, if you are

respectful and pay him appropriately. The plumber’s end is to make a living with his plumbing skills.

By paying him the agreed-upon amount, you are making his end (earning a living) your end. Thus, in

this situation, you both are effectively advancing each others’ ends at the same time and thus treating

each other both as ends and means.

One way to think of the idea of treating someone as ends and means is that, when you treat people

as ends, you make their ends your ends, and when you treat people as means, you force them to make

their ends your ends. To explain, let’s look at an example from the first formulation. Since the first

formulation and the second formulation of the categorical imperative are supposed to be saying the

same thing, they should come to exactly the same conclusions about what’s right and wrong. Thus,

since we discovered earlier that it’s wrong to make a false promise, then the second formulation

should also tell us that false promises are wrong. In our example, you made the false promise because

you needed to borrow money to pay off debts; thus, your end was to pay off debts, and by lying to

your friend, you are forcing him to make your end (paying off debts) his end. If you told your friend

that you needed money and might not be able to pay it back, your friend would be able to decide. He

might decide to make your end his end (to pay off your debts for you), but by depriving him of that

choice, you are treating him as an object. For similar reasons, we can also conclude that any time we

deceive someone, we are treating the person as a mere means to our ends.

We can also look at the other example from the first formulation discussed above and see that it leads

to the same conclusion. Kant argued that we have an obligation to sometimes help out others in need.

To help people out is to make their ends our ends. For example, if you see that someone is poor and

hungry, his end at that point might be to get food. If you give him food or money to buy food, you are

making it your end to feed him. Since you should treat people as ends, then that means you should

sometimes provide people with help.

In addition, the second formulation also includes the idea that we shouldn’t treat ourselves as mere

58 KANTIAN DEONTOLOGY

means to ends. In the Groundwork, Kant gives two examples of duties to oneself: we shouldn’t commit

suicide, and we should cultivate some of our useful talents. In the Metaphysics of Morals, Kant presents

several more, including that you should not pursue greedy avarice, stupefy yourself with excessive

food or drink, nor be excessively servile.

On the Morality of Suicide

The question of the morality of suicide was a heated topic of debate in the Western intellectual tradition in

Kant’s day. Though we nowadays tend to think of suicide as a mental health issue and thus as a medical concern,

it used to be much more often considered a moral concern. Suicide was a punishable crime in England until

1961, and both attempted and successful suicide could lead to serious penalties, with similar laws in many other

countries.

The immorality of suicide was espoused by several influential Christian thinkers. Augustine, in his City of God (Book I, ch. 20), declared that the commandment, “Thou shalt not kill,” included suicide. Thomas Aquinas, in his

Summa Theologiae (II-II, Q. 64, A. 5), argued that (1) since our natural inclination is to try to stay alive and extend our life as long as possible, suicide is unnatural and therefore wrong, that (2) since our community benefits from

our continued existence, then suicide harms the community, and that (3) since our life is not our own, being a

gift from God, then committing suicide is a crime against God. Thus, suicide harms the self, society, and God.

Dante in his Inferno (Canto XIII), placed those who had committed suicide in the Second Ring of the Seventh Circle of Hell, for those who commit violence against the self ([1320] 1995).

Such arguments were influential in Kant’s day. His own arguments in the Groundwork are that (1) since suicide is motivated by self-interestedness (by a desire to end the sorrows a person is experiencing) and since self-

interestedness normally impels us to try to improve our life, then suicide is self-contradictory and thus wrong

(4:422) and that (2) by committing suicide one is treating oneself merely as a means and not as an end (4:429).

Also, in his Metaphysics of Morals, he argues that suicide effectively harms the morality in the world by destroying one’s capacity for morality within oneself (6:423).

There were other authors who disagreed. Much earlier, in Utopia, Thomas More argued that suicide should be permitted in cases when people suffer from unpleasant and incurable diseases ([1516] 2012). Arthur

Schopenhauer took the view in On Suicide that suicide, though not a sensible choice in most cases, can’t be considered morally wrong because your life and person are the things that most clearly belong to you ([1851]

2015). Thus, you can dispose of them how you wish. David Hume, in his essay Of Suicide, published posthumously, targeted Aquinas’s arguments that suicide harms self, society, and God: (1) Sometimes suicide

doesn’t harm the self, since in some cases, continuing to live is worse than death. (2) Suicide doesn’t harm

society because, by depriving society of oneself, one is merely withdrawing benefit, not harming society (and if

one is actually a burden on society, then one does society great benefit). And (3) one’s life must be one’s own,

otherwise it wouldn’t make sense to praise people for risking their life for others ([1777] 1998).

Such a list of duties does raise the question, though, of what it means to treat oneself as a mere means.

The idea that we could treat ourselves as a mere means seems somewhat implausible, and if we look

at it the way we explained it before (to treat people as a mere means is to force them to make their

ends our ends), then it doesn’t make sense. Our ends are our ends and can’t be anything other than

our ends.

ETHICS 59

Perhaps, by treating oneself as a mere means, one is not treating oneself with respect—as a person

with dignity and with unlimited value. We can see how this might apply to duties like not being too

servile or not being too avaricious. By being excessively servile, you are debasing yourself, making

yourself into a thing to be used by someone else. And with excessive greed, you are elevating the value

of money over and above your own value.

Another way to think about it is that, by treating oneself as a mere means, one is not giving proper

respect to the humanity within oneself. The second formulation specifically forbids treating the

humanity in ourselves and in others as a mere means. Concerning our humanity, Kant means mostly

our capacity for rational human thought. So, by treating oneself as a mere means, one is not giving

proper value to this rational capacity. One can see this in the case of stupefying oneself with excessive

drink. Excessive drunkenness and opium use—the two examples Kant specifically mentions in the

Metaphysics of Morals—dull one’s thinking, and Kant describes them as turning a person into an

animal, though he seems to concede that some level of moderate alcohol consumption or opium

use might be permissible (6:427-6:428). Similarly, in the Metaphysics of Morals, his argument against

suicide is that, “To annihilate the subject of morality in one’s own person is to root out the existence

of morality itself from the world” (6:423). That is, by committing suicide, you destroy some of the

morality in the world by destroying your capacity for morality.

Kant on Animal Rights

Kant defines what counts as a person in terms of their capacity for rationality. This means that any being not

capable of rationality lacks dignity and thus we don’t have the same moral obligation to not treat them as mere

means. One of the significant implications for this is how it affects our duties to nonhuman animals. Kant’s ideas

would imply that we can treat such animals however we wish. In terms of animal rights, whether animals have

any rights (for example the right not to be mistreated, harmed, or killed), Kant would say that since they are not

rational, they have no rights.

Kant does argue that it’s wrong to treat animals cruelly. This duty is derived from a person’s duty to himself. As

Kant writes in The Metaphysics of Morals: “With regard to the animate but non-rational part of creation, violent and cruel treatment of animals is far more intimately opposed to a human being’s duty to himself, and he has a

duty to refrain from this; for it dulls his shared feelings of their suffering and so weakens and gradually uproots

a natural predisposition that is very serviceable to morality in one’s relations with other people” (6:443). That is,

he is saying that mistreating animals will dull one’s compassion towards other living beings and thus make one a

less virtuous person.

He is clear that “the human being is authorized to kill animals quickly (without pain),” which indicates that killing

animals for food, or even hunting them for sport, is permissible, so long as it is done humanely. However, he does

partially disapprove of using animals for medical experiments: “agonizing physical experiments for the sake of

mere speculation, when the end could be achieved without these, are to be abhorred.” This passage was

probably directed at the then-common practice of animal vivisection, but his words would suggest that animal

experiments for medical purposes, in cases when the goal is to save human lives, might perhaps be permissible.

Though we should emphasize that this duty to not mistreat animals is only because of the harm one might do to

oneself by this cruelty to animals: “it is always only a duty of the human being to himself” (6:443).

60 KANTIAN DEONTOLOGY

P RO B L E M S W I T H T H E S E C O N D F O R M U L AT I O N

One of the main problems with the second formulation of the categorical imperative is that it’s

somewhat vague. There are clear-cut cases of using people as mere means, such as slaveholders

exploiting their slaves, but what about something more ambiguous like an employer underpaying his

employees? The employer is advancing the employees’ ends by paying them, but clearly would better

promote their ends if wages were raised. But what exactly counts as “underpaying” is unavoidably

vague, and the categorical imperative doesn’t give clear guidance.

Another problem is that it doesn’t seem that morality is entirely about not treating people as mere

means to ends. The categorical imperative is supposed to be the sole principle of morality. Thus, we

should be able to derive all moral duties from it. But it seems like there are actions that are morally

wrong but which don’t amount to treating anyone as mere means. For example, the destruction of the

natural world through carelessness or negligence seems wrong. If I accidentally start a forest fire by

setting off fireworks when there is high fire risk, aren’t I morally culpable? But in what way have I

treated a person merely as a means? The forest is not rational and thus is not an object of direct moral

consideration. Kant does write, “A propensity to wanton destruction of what is beautiful in inanimate

nature is opposed to a human being’s duty to himself” (6:443). But if it’s through neglect, it doesn’t

appear to be treating any person merely as means. Similarly, what about our obligation to care for the

dead? If my mother wanted to be given a Christian burial and instead I simply left her body out in the

woods, that would seem to be quite immoral. But how would we explain that in terms of treating her

as a mere means? The body is no longer a person; it lacks humanity, rationality, and thus is a thing,

and it’s permissible for us to treat things as means. There are perhaps ways a defender of Kant could

explain why these are wrong within a Kantian framework, but it is a potential limitation of the theory.

Kant is only able to derive obligations to not mistreat physical objects and non-rational living things

from obligations to oneself and other rational beings. By misusing objects and animals, we habituate

ourselves to not giving others the proper respect, which thereby debases our character. But it does

seem strange to say that the reason why it’s wrong to damage non-human life is because it’s harmful

to oneself.

T H E T H I R D F O R M U L AT I O N O F T H E C AT E G O R I C A L I M P E R AT I V E

Kant gives a third formulation of the categorical imperative based on the notion of a kingdom of

ends. By kingdom, Kant explains, “I understand a systematic union of various rational beings through

common laws” (Groundwork 4:433). By a kingdom of ends we’re to imagine an interconnected world

of rational beings where everyone is treated as an end and treats everyone else as ends and everyone

shares the same set of laws.

Kant explains the third formulation as, “act in accordance with the maxims of a member giving

universal laws for a merely possible kingdom of ends” (Groundwork 4:439).

As mentioned, Kant believes that autonomy is necessary for morality. Kant is here emphasizing that

we are each the creators of our own moral rules. We are fully autonomous beings, and if our morals

were imposed on us, then that would undermine our autonomy; we would no longer fully decide our

actions. To maintain full autonomy, everyone must be the creator of their own moral rules.

ETHICS 61

However, if everyone is creating their own moral rules, then wouldn’t people disagree on what is right

and wrong? Kant doesn’t believe so. He believes that the categorical imperative is the only rational

moral rule, and he also believes that we can derive a complete, consistent set of moral duties from the

categorical imperative. Thus, every person who is fully following their rationality will agree on what

is right and wrong.

C O N C L U S I O N

Despite many of the criticisms to which Kant’s ethics has been subject, it remains one of the most

influential ethical theories in contemporary Western ethics. Many thinkers agree with its emphasis

on ethics being fundamentally rational and being justifiable through reason. The first and second

formulations of the categorical imperative also do have great intuitive appeal. Despite the abstract

way that the first formulation is expressed, its core meaning is that ethical rules should be universal

and that if any rule can’t be universalized, it shouldn’t be followed. This appeals to our sense that all

people deserve equal moral consideration and we shouldn’t make special exceptions for ourselves or

others. And the second formulation speaks to the idea that we are beings with intrinsic value and

with dignity, and to use people as if they are objects or tools is deeply immoral. Kant has put these

intuitions into a sophisticated and carefully thought out framework that remains, to this day, a very

useful way of thinking about difficult moral questions.

In the eighteenth and nineteenth centuries, early feminist writers, including Mary Wollstonecraft

(1759-1797), John Stuart Mill (1806-1873), Sojourner Truth (1797-1883), and Elizabeth Cady Stanton

(1815-1902), began to address topics related to the political, economic, and educational status of

women, and “women’s morality” (Tong and Williams 2018). This was partly motivated by a growing

awareness of the real inequalities between men and women, including legal and social restrictions and

prohibitions. These authors argued that disparities in educational opportunities, and the restrictions

across race and gender of roles and responsibilities open to women, prevented women from fully

developing as people and citizens (Wollstonecraft [1792] 2004). This was First Wave feminism, and

it accomplished significant progress on emancipation and enfranchisement for women and visible

minorities in the West.

Betty Friedan by Fred Palumbo via The Library of Congress. This work is in the public domain.

In the twentieth century, Betty Friedan (1921-2006) would

report similar phenomena among her white university-

educated peers in the 1950s United States, who had returned to

the home to be full-time housewives. Friedan wrote that this

group of women appeared to suffer a sort of stunting, an

erosion of their abilities, and a freezing of personal, intellectual,

and moral development into a childlike and immature state

(Friedan [1963] 1997). It should be noted, though, that this was

not the experience of black women in the US, who often worked

outside the home, frequently in the employ of white women,

nor the experience of working-class women across races

(Collins 1989). However, women found significant

commonalities among themselves in the disparity of political

and employment rights compared to men in their social groups

(Thompson 2002). Around the same time in France, Simone de

Beauvoir (1908-1986) published her seminal work examining

the situation of women in French society, describing women’s

second-class status as founded upon the social and political

interpretations of biological differences between male and female (de Beauvoir [1949] 2014). The

work of de Beauvoir, Friedan, and many others spurred Second Wave feminism among women in

Europe and North America, as they began to examine anew the cultural, political, and moral positions

that women occupied. Second Wave feminists focused their efforts on such issues as reproductive

rights, domestic and sexual violence, paid maternity leave, and equal pay in the workplace.

While issues surrounding women’s political and moral development had long been a concern to

feminists of the First and Second waves, it was around the end of the Second Wave and the beginning

of the current Third Wave (roughly around the late 1980s and early 1990s), that writers began

to think about the need for a specifically feminist ethics. Up to this point, moral theories (like

deontology or consequentialism) had largely ignored or remained unaware of the specific perspective

and experiences of women, privileging the experiences and perspectives of the “universal” or “neutral”

position. Feminists, however, pointed out that this “universal” perspective was a specifically white

male perspective. Alison Jaggar wrote that one problem with traditional ethics at the time was (and

potentially still is) that it views as trivial the moral issues that arise in the so-called private world,

the realm in which women do housework and take care of children, the ill or infirm, and the elderly.

In its formulation of the “neutral” perspective, traditional ethics was charged with favoring “male”

ways of moral reasoning that emphasized rules, rights, universality, and impartiality over “female”

ways of moral reasoning that emphasize relationships, responsibilities, particularity, and partiality.

Additionally, Jaggar points out that traditional ethics had under-rated culturally feminine traits like

“interdependence, community, connection, sharing, emotion, body, trust, absence of hierarchy,

nature, immanence, process, joy, peace, and life” ( Jaggar 1992, 363-364).

Thus, an ethics that paid particular attention to these traditionally undervalued virtues, principles,

values, perspectives, and ways of knowing was required to provide a full understanding of human

experiences and moral life. In the Third Wave, feminists began to criticize and discuss the various

ETHICS 65

shortcomings of the Second Wave, including its marginalisation of the voices and perspectives of

women of oppressed races, ethnicities, sexual identities, and socio-economic positions (Combahee

River Collective 1977; Mohanty, Torres, and Russo 1991). A feminist ethic, which paid attention to

these different identities and perspectives, became centrally important to taking women’s lives and

experiences seriously, and central to eliminating oppression of women, sexual minorities, and other

oppressed groups. Thus, Jaggar framed feminist ethics as the creation of a gendered ethics that aims to

eliminate or at least ameliorate the oppression of any group of people, but most particularly women.

T H E E T H I C S O F C A R E

Care ethics, as it has become known, is an early feminist ethic that arose out of reactions to popular

psychoanalytical accounts of male and female development in the mid-twentieth century, and the

questioning of women’s roles in society. This ethic began from observational studies in psychology,

and later became a positive normative account of moral behavior. The early formulations of care

ethics were criticized by both feminist theorists and philosophers working in other moral traditions.

The objections to these early formulations are important, and have led to useful and interesting

developments. Care ethics has advanced as a normative theory, but has perhaps made its strongest

contribution as a metaethic, a position from which to begin our moral reasoning, rather than as a tool

to use in sorting out particular moral cases or dilemmas.

Early Formulation

In her psychological analysis of women’s moral decision-making in the 1980s, In a Different Voice,

Carol Gilligan claimed that she found a difference in the way men and women perceived moral

problems. While men focused on justice and rights, women were more likely to think about

relationships in making moral decisions. In examining the question of abortion, Gilligan wrote,

[W]omen’s construction of the moral problem as a problem of care and responsibility in relationships rather

than as one of rights and rules ties the development of their moral thinking to changes in their understanding

of responsibility and relationships….Thus the logic underlying an ethic of care is a psychological logic of

relationships, which contrasts with the formal logic of fairness that informs the justice approach. (Gilligan

1982, 73)

For Gilligan, this ethic of care particular to women develops in three stages. First, a woman exhibits

a focus on caring for the self in order to ensure survival, which is accompanied by a transitional

phase in which this mode of thinking about the self as primary is criticized as selfish. Following this

critical phase, a new understanding of the connections between one’s self and others leads to the

development of a concept of responsibility. Gilligan wrote that this concept of responsibility is fused

with a “maternal morality,” which is focused on ensuring care for the dependent and unequal people

in one’s circle. At this stage, the Good is defined in terms of caring for others. However, Gilligan

continues, too much of a focus on others in this second stage of moral development leads to an

imbalance of attention, which means that a woman must reconsider the balance between self-sacrifice

and the kinds of care included in conventional ideas of feminine goodness. The third phase, then, is

one which balances the self with others, and focuses on relationships and a new understanding of the

connections between the self and others. The central insight in this ethic of care, Gilligan writes, is

that the self and others are interdependent (Gilligan 1982).

66 FEMINIST ETHICS

A few years after Gilligan, Nel Noddings published Caring: A Feminine Approach to Ethics and Moral

Education, which provided a deeper analysis into the people—the care provider and the care

receiver—and the processes involved in caring. In this book, Noddings argued that morality requires

a person to have two emotions. The first of these emotions is a sentiment of “natural care.” Noddings

describes this care as pre-ethical; the caretaking that a mother engages in for her child, or a maternal

animal for her offspring are equally examples of this natural care. As Gilligan also argued, Noddings

says that concern for others, or recognition of others’ concern for us, gives rise to a conflict between

responding to the needs of others and taking care of our own needs. This conflict gives rise, in turn,

to the opportunity for “ethical caring,” or responding to the recognition that another has needs, and

that we are in a position to meet these needs, and further acknowledging that this situation makes a

moral claim on us. However, in many cases we can recognize and respond to another’s needs by way

of natural care, a disposition to care for the other that arises spontaneously in us, rather than by way

of ethical care, which one would only act from if natural care has failed. In this way, natural care is

preferable to ethical care on Noddings’ account (Noddings 1984).

Objections

A number of objections have been raised to Gilligan’s and to Noddings’ formulations of an ethics of

care within psychology, moral theory, and feminist thought. Of those raised by feminists, the most

powerful objections focus on the potential for care ethics to “essentialize” the caring relationship.

This objection says that care ethics may reduce the relationship of care to essential features which

are then linked to “woman’s nature” in a way that calls upon and reinforces gender-based stereotypes

(e.g. women are more sensitive and caring than men). These objections stress that even if women are

(for social, cultural, biological, or interconnected reasons) better at providing or giving care than are

men, it may still be “epistemically, ethically, and politically imprudent to associate women with the

value of care” (Tong and Williams 2018). The worry is that intimately linking women with caring may

“promote the view that women are in charge of caring or, worse, that because women can care, they

should care no matter the cost to themselves” (Tong and Williams 2018; emphasis added).

From a Marxist-inspired feminist perspective, Sandra Lee Bartky (1935-2016) expands on this worry

in her 1990 book, Femininity and Domination. Bartky argues that, rather than providing women with

a valued and esteemed role in a man’s world, women’s activities in “building men’s egos and binding

men’s wounds” ultimately disempower women (Tong and Williams 2018). She claims that the kind of

affective labor (work that significantly involves one’s having or showing certain emotions) undertaken

by women in providing care for a family, and in some service-oriented occupations, causes them

to disconnect from their own basic emotions and feelings. In service occupations, such as being a

flight attendant, Bartky says the employee must force their own feelings into the background, and be

nice (for example) regardless of the behavior of the client in front of them. This kind of emotional

labor risks blurring the distinction between “real” feelings of wanting to be friendly and nice and

“inauthentic” feelings that are generated by the employment obligation to be friendly and nice.

In the home, something similar happens. Bartky writes that many wives and mothers say that the

experience of caring for their husbands and children, even when difficult, provides their lives with

fulfillment and meaning. The more they care, the more they view themselves as the glue of the family

that holds everything together for everyone else (Tong and Williams 2018). But, and importantly for

ETHICS 67

Bartky, such subjective feelings of empowerment are not the same as actually having power. A lack

of power in the family means that a woman is obligated to take on these caring roles and, like the

flight attendant, to force her own feelings down when they do not match with the expected behavior

of a good wife or mother. So, like in employment situations, the required emotional work within the

family risks blurring the distinction between a woman’s real feelings of care and satisfaction with

feelings that are generated by her sense of obligation and of what it means to properly perform her

role.

In employment and in the household, a woman’s emotional exploitation is linked closely to her

economic and material oppression. Marxist-inspired feminists, such as Ann Ferguson, have argued

that economic disadvantage within the household is analogous to capitalist exploitation of laborers.

Ferguson analyses the “sexual division of labor” within a household, in which women are responsible

for producing four main categories of goods. These are children, household maintenance, care (of

children and of men), and sex (Ferguson 1991). Women and girls are taught to take pride and

satisfaction in the production of these goods, while men learn that these are women’s work, and

therefore not their responsibility. At the same time, the production of these goods is disvalued, and

the desire to do this work is connected to the idea of “being a woman.” Thus, the labor that goes

into the production of these things goes largely unrecognized. Bartky argues that in providing this

care to her husband or children, a woman is exploited in such a way that her family benefits and has

their interests advanced while she suffers damage to her own interests. In a similar vein, Sheila Mullet

argues that when material conditions of oppression appear within a household, real relationships

of care are prevented from forming. She argues that a woman is not in a position to truly care

for someone if she is economically, socially, or psychologically forced to do so (Mullet 1988). Thus,

real caring cannot occur under conditions characterized by domination and subordination. Only if

women are fully equal to men can women take on the emotional work of care without fearing that

men will take advantage of their labor.

Responses and Developments

Care ethics has continued to advance in recent years, in part by responding to the objections of

various feminist and non-feminist thinkers. Care ethics made an important and valuable contribution

in identifying that people are necessarily interconnected beings. The importance of care for morality

and personal development gave rise to theories incorporating relational and intersectional

conceptions of various ethical values, which will be discussed below.

A number of authors, such as Virginia Held and Eva Feder Kittay, have continued to develop care

ethics into both a moral theory and a kind of metaethical framework, from which ethical obligations

can be derived and in which certain moral principles and values may be grounded. There are three

foundational theoretical commitments in the ethics of care that have been established amongst

care theorists at this point (Sander-Staudt 2017). First, persons are understood to have varying

degrees of dependence and interdependence. More about this will be said in the following section,

Relational Theory. This perspective in care ethics contrasts with deontological and consequentialist

moral theories that often view persons as having independent interests. Second, care ethics holds

that anyone who is particularly vulnerable to one’s choices and their outcomes deserves extra

68 FEMINIST ETHICS

consideration when making decisions. Third, the contextual details of situations must be part of the

decision-making process, in order to safeguard and promote the actual interests of those concerned.

Further, in keeping with some of Noddings’ early views, Held and Kittay have argued that the

principle of justice can be grounded in care. Held has said that while care can exist without justice,

as it may do within unjust family relationships, justice cannot exist without care. In order for an

inkling of justice to take shape in our minds, we must first express concern for the condition of

another, and this is an expression of care. So, care is “deeply fundamental,” perhaps an ethical proto-

value, motivating any further moral sentiment (Held 2005, 17; Tong and Williams 2018). In criticising

Rawlsian formulations of justice as fairness, Kittay has argued that relationships of dependency

characterized by care are such a fundamental part of human life that any theory of justice that leaves

these out cannot achieve a just or fair society. Given that each person will experience dependency

upon someone who takes on the responsibility to care for them in prolonged and significant episodes

throughout one’s life, such relationships and the shift in power, labor, and interests that happen within

them, must be attended to by any theory attempting to form a fair distribution of benefits and goods

in society. An ethic of care, thus, must be central to formulations of justice (Kittay 1997).

Furthermore, Held sees care ethics as a normative moral theory, something that can provide robust

tools for determining morally good outcomes in specific dilemmas or challenges. By denying the

appeal to universal moral principles, by valuing emotional responses, and by looking at the specific

relationships that we have with those “particular others for whom we take responsibility,” Held argues

that care ethics can provide answers about what we ought to do in specific scenarios (Held 2005, 10).

However, even moral theorists who do not explicitly subscribe to an ethics of care may recognize

the metaethical contribution it makes to our understanding of human interaction and moral life.

The first of the three theoretical commitments of care ethics, that humans are essentially social and

interconnected beings with varying degrees of independence, and not the sort of entities that pop into

existence entirely able to support themselves or fully develop in the absence of social relationships

characterized by interdependence and care, has had significant influence on the development of

relational theories of identity and agency, as we shall see below. Thus, the metaethical notions

grounding care ethics have become ingrained in feminist understandings of moral psychology,

personal autonomy, rights, and responsibility.

R E L AT I O N A L T H E O R Y

A metaethics of care provides the background for a group of ideas sometimes called “relational

theory.” Here, relational autonomy and relational identity will specifically be discussed. Natalie Stoljar

writes that the term “relational” makes a metaphysical claim, which denies a notion of “atomistic”

personhood, “emphasizing instead that agents are socially and historically embedded, not

metaphysically isolated, and are, moreover, shaped by factors such as race and class” (Stoljar 2015).

Thus, the insights provided by early formulations of care ethics provide a portion of the metaphysical

and metaethical starting point for seeing persons as always and unavoidably interconnected. In other

words, insights from care ethics provide foundational building-block concepts for an interpretation

of reality, and what our moral theories should take into account. Thus, interpersonal and social-group

ETHICS 69

relations are an important feature of the world, and must accordingly form an important part of our

moral theorising.

Autonomy

When referring to autonomy, Stoljar writes that the term “relational” may serve to deny that

autonomy requires self-sufficiency, as it had traditionally been formulated. In most pre-feminist

formulations of autonomy, especially following the development by various scholars of Immanuel

Kant’s theory, a model of cool and detached reasoning, unconcerned with personal or familial

commitments, became a requirement of independent decision-making. However, this way of thinking

about autonomy is problematic because, under such requirements, one must either acknowledge that

no person fully meets the criteria, or willfully ignore that any person’s ability to be independent is

facilitated by the ongoing care provided to them by others. If we move away from this idea of what

autonomy means, and acknowledge that relationships of care and interdependence are valuable and

morally significant, then as Stoljar argues, any useful theory of autonomy must at least “be ‘relational’

in the sense that it must acknowledge that autonomy is compatible with the agent standing in and

valuing significant family and other social relationships” (Stoljar 2015).

In response, many theorists working on questions of agency, decision theory, and ethics, among

other areas, have adopted an account of autonomy that is relational (Christman 1991; Westlund 2009;

Benson 1991). Relational theories of autonomy generally start with the minimal acknowledgment

that we begin as non-autonomous beings, as infants, and develop into autonomous beings gradually

as we learn various sets of skills and gain specific abilities central to making our own decisions,

from the mundane to the momentous. Many relational theories of autonomy also take into account

that our autonomy is impacted by the process of socialisation (Benson 1991; Meyers 1987), or may

be suspended at various times in our lives. For example, we may become gravely ill, and become

comparatively much more dependent upon others for the duration of the illness. We may also become

less autonomous as we enter into the later decades of life. Autonomy, thus, may be something that is

a matter of degrees or stages of life (Meyers 1987; Friedman 1997). Relational theories of autonomy

can account for these facts of human existence, attending to the importance of our close relationships

in facilitating decision-making and the achievement of a good and satisfying life.

70 FEMINIST ETHICS

Identity

Relational identity is another theoretical perspective on

human development and experience that is metaethically

informed by care and by recognition of intersectionality:

the intersecting identities people hold. Intersectionality

was conceptualized by Kimberlé Crenshaw, reflecting the

reality of black women’s identities as being formed within

the hierarchical power structures of both gender and race

(as well as class, sexual orientation, ability, and so on)

(Crenshaw 1989; 1991). In political or social movements

that are oriented around “single-axis” issues, e.g.

exclusively race or exclusively gender, Crenshaw argued

that people with more than one of these identities were

further marginalized. Crenshaw’s work is politically

important, and important to a feminist ethic which seeks,

as Jaggar said, to theorize for all oppressed people and

especially women. The acceptance of intersectionality has

led to a recognition that persons are complex, and may

simultaneously experience realms of their identity that are

privileged while other realms of their identity are

oppressed. A feminist ethic must begin from the

recognition of these intersecting dynamics of power within

and among individual women and social groups.

As such, Françoise Baylis and Margaret Urban Walker have separately argued that the formation of

the self and personal identity are ongoing social processes, happening with other people and the

systems around us. Baylis writes that, since persons are interdependent beings, a person’s identity,

“including her traits, desires, beliefs, values, emotions, intentions, memories, actions, and

experiences,” is informed by her relationships, which have varying degrees and kinds of intimacy and

interdependence (Baylis 2011, 109). A person’s public and private interactions help to structure her

perception of herself and define her place in the world.

For relational identity theorists, a person is importantly constituted by the relationships and

interactions they have. Baylis writes that one’s identity exists in the “negotiated spaces between my

biology and psychology and that of others,” forming a “balance between self-ascription and ascription

by others” (Baylis 2011, 110). Certain parts of myself may feel like they were created by me or perhaps

were “always there,” in the sense that I might not be able to easily identify the source of influence that

shaped them, but all parts of me are (in)formed by interactions with the social and political world. This

way of conceptualizing identity pays attention to the fact that as infants we enter a world already full

of meaning. The particular meanings attached to our bodies (about, for example, skin color, biological

sex, or physical ability) and certain personal characteristics (such as gender expression or sexual

identity) precede us in space and time. As Walker writes, women and men in situations of oppression

or subordination may find themselves subject to socially normative narratives about their identities,

which are coercive and disadvantaging (Walker 1997). These narratives exist in the world into which a

ETHICS 71

person is born and grows up, impacting many aspects of their identity formation and expression. The

recognition that we only ever exist within such narratives and interpersonal relationships of various

kinds thus forms the backdrop for relational theories of identity formation and maintenance.

C O N C L U S I O N

The development of feminist ethics stemmed from the recognition that the experiences and

perspectives of some groups in society, including people of a minority race or ethnicity, people with

disability status, people from lower socio-economic levels, and women, as well as people whose

identities cut across these groupings in various ways, had been ignored or devalued by mainstream

or traditional ethics, and has since been attempting to remedy this in conjunction with other anti-

oppression movements. In a metaethics of care, the interdependence of human beings is taken as an

enabling and necessary feature of life, rather than as something to be shaken off to achieve the greatest

independence of thought or feeling. By acknowledging that “independence” is only a relative state,

and that we are all, to various degrees at different stages of life, dependent on others for care and

survival, feminist ethicists have achieved a revision in the way that important moral concepts, such

as autonomy and personal identity, are conceived. That much caring labor is yet under- or de-valued,

that its performance often still falls to women within households and disproportionately to minority-

group women in the workforce, and that women still face economic disadvantages as compared to

men within their social and cultural groups, remains a challenge for feminist ethicists and political

philosophers.

As the world’s leading ant expert, Edward

Wilson could have led a tranquil and joyous

academic life. But in his book Sociobiology from

1975, Wilson extended his work on evolutionary

explanations of social behavior—which helped

him a great deal in understanding the behavior

of social animals like ants, bees, and horses—to

human behavior. As Wilson later wrote, all of the

book’s 575 pages were well received but for the

last, brief chapter on human evolution (Wilson

2002, vi). In that chapter, Wilson suggests that

evolution could explain moral behavior in

humans: humans are moral, prosocial animals

because being moral and prosocial had

evolutionary advantages. Indeed, he urged that

“scientists and humanists should consider

together the possibility that the time has come

for ethics to be removed temporarily from the hands of the philosophers and biologicized” (Wilson

2002, 562).

Wilson’s suggestion caused outrage far beyond the academic ivory tower. Many associated

evolutionary theory with crude claims about the “survival of the fittest,” which some regimes used

to justify wars and euthanasia, and they feared that approaching ethics from the evolutionary

perspective would justify racism, sexism, and imperialism. 1 In effect, Wilson’s academic life after

the publication of the book was far from tranquil; his talks were controversial, shouted down by

1. Cf. Segerstrale (2000)

ETHICS 75

protesters, and at a conference in 1978, an opponent even expressed his dismay by emptying a can of

water over him.

However, looking behind Wilson’s sensational rhetoric of “removing ethics from the hands of the

philosophers” we find a more level-headed claim about methodology in ethics (Wilson 2002, 562).

Wilson called for studying ethics just as we study other social, psychological, or biological phenomena.

In other words, Wilson called for a so-called naturalistic approach to ethical questions (which will

be explained in further detail below). Of course, we can ask many different questions about ethics

and, as we will see, some are more suited to a naturalistic approach than others. But the debate

about the legitimacy of evolutionary ethics has largely abated in favor of Wilson’s proposal. Many

aspects of evolutionary ethics are thriving and have led to exciting research programs that have made

tremendous progress since Wilson’s book. And Wilson, rest assured, came out of the controversy

emboldened and unscathed. It seems that he did lead a joyous academic life after all.

This chapter first introduces naturalistic approaches to ethics more generally and distinguishes

methodological ethical naturalism (the focus of this chapter), from metaphysical ethical naturalism.

The second part then discusses evolutionary ethics as a specific variant of methodological ethical

naturalism. After introducing the concepts of evolutionary theory that are relevant for evolutionary

ethics, I will sketch the history of evolutionary ethics, which offers an interesting lesson about why

it became a controversial topic, and then focus on four central questions about ethics that can be

approached from within the framework of evolutionary ethics:

1. What should we do?

2. Why are we moral?

3. Are there moral facts?

4. Can we have justified moral beliefs and moral knowledge?

Wilson advocates methodological ethical naturalism, which is primarily a view about the best ways

to study ethics. Naturalists in this sense argue that at least some ethical questions can be studied just

as we try to answer questions in other fields of scientific inquiry. Ethics, in other words, is continuous

with science.

A central commitment of methodological ethical naturalism is to widen the net of our sources

for ethical inquiry. For example, we can use anthropological, psychological, biological, and literary

sources to inform our theorizing about ethics. 2 Such a multitude of sources contrasts with the

more traditional way of doing moral philosophy by conceptual analysis. Conceptual analysis is a

method often used by philosophers to investigate ethical questions. It involves reflection about

when a concept, such as “goodness” or “freedom,” applies and how it relates to other concepts.

Using conceptual analysis to understand what moral goodness is, for example, means analyzing

the conditions in which the concept “moral goodness” applies. Conceptual analysis is guided by

2. E.g. Kitcher (2011); Flanagan (2017); Appiah (2009)

76 EVOLUTIONARY ETHICS

one’s understanding of and intuitions about the concept in question. Since much of the academic

philosophy studied by North American and European philosophers still is, or has been, done by North

Americans and Europeans (despite the fact that academic philosophy is being done in other parts

of the world, too), many existing conceptual analyses of ethical terms are really conceptual analyses

of Western concepts. However, psychologists and philosophers have argued that intuitions about

(ethical) concepts vary quite significantly. 3 If these claims are true, it would be a problem insofar as we

want to learn what moral goodness is, rather than what the concept of moral goodness of Western academics

is. Hence, the naturalist has a good case for taking into account more than just (predominantly

Western) intuitions. Evolutionary thinking is one such source, and we will cover it in greater detail

below.

In contrast to methodological naturalism, which is primarily a view about how to conduct ethical

inquiry, metaphysical ethical naturalism is primarily a view of what exists. Both views are related

but distinct, as an analogy with ghosts illustrates. It would be one thing to find out in scientifically

respectable terms why people believe in ghosts, which would be methodological naturalism, but quite

another to say what ghosts are in scientifically respectable terms, which would be the goal of the

metaphysical naturalist. 4

Metaphysical naturalists say that there are no non-natural or supernatural entities in this world. On

most accounts of drawing the line between “natural” and the rest, this excludes God or gods, ghosts,

human spirits, or a soul that is not part of the physical body. Morality seems to fall on the non-natural

or supernatural side of things to many philosophers. One reason is that moral facts seem quite unlike

ordinary facts about, say, the weather or geology, due to their normative force. To illustrate, if I state

an ordinary fact like “Mitt went to the grocery store” or “gold is denser than iron,” I describe a state

of the world, but I do not seem committed to acting in one way or another. In contrast, if I say “it

is morally wrong that Mitt stole the money,” I not only describe the world, but also seem to commit

myself to act in a certain way. It sounds strange to say, for example, that “it is morally wrong that Mitt

stole the money but we should do nothing about it.” Moral facts, it seems, have a certain prescriptivity

built into them, and this is one reason it seems that moral facts cannot straightforwardly be reduced

to natural facts. (To wit, moral facts, such as the fact that killing is wrong, not only describe the world

like other facts, but they also give reasons for acting, or prescribe certain courses of action.)

As a solution, some metaphysical naturalists abandon moral facts altogether. Since there are no moral

facts at all on this view, this is, of course, a straightforward way to live up to one’s naturalistic

aspirations. 5 Typically, however, when moral philosophers speak about moral naturalism, they have in

mind a version of metaphysical ethical naturalism that is committed to two theses. First, moral facts

exist. Second, moral facts can be described in purely natural terms. 6 For example, consider the moral

theory utilitarianism (see Chapter 5). A simple version of utilitarianism holds that the only thing

of intrinsic value is happiness and that our only obligation is to maximize happiness. On this view,

moral properties reduce to the property of being conducive to happiness, which is a psychological

quality that fits quite well into the worldview provided by science. 7 The major philosophical project of

metaphysical naturalists is to explain how exactly moral facts relate to natural facts, which raises some

fascinating issues. 8 For present purposes, it is important to note that you can be a methodological

naturalist without being committed either to one of the two forms of metaphysical naturalism or to

metaphysical naturalism in general. That means you can embrace methodological naturalism but deny

that there are only natural facts. From now on, we will focus on methodological naturalism, and in

the next section, we will see how evolutionary ethics is a particular instance of methodological ethical

naturalism.

Evolutionary Theory and Ethics

Evolutionary ethics takes into account the findings of human evolutionary psychology, a field of study

that explores how evolutionary forces helped shape not only how humans function and what we look

like (what evolutionary biologists call the human “phenotype”), but also how we behave, feel, and

think. 9 Evolutionary ethics is thus a way in which we can widen the net of sources that inform ethical

inquiry.

Evolutionary psychology itself is based on the theory of evolution by natural selection applied to

human beings, first described by Charles Darwin in 1871 in his book The Descent of Man. In this book,

Darwin argued that we humans are the descendants of a “hairy quadruped, furnished with a tail and

pointed ears, probably arboreal in its habits, and an inhabitant of the Old World” (Darwin 1871, 389).

Darwin’s theory describes natural selection as the differential survival and reproduction of

individuals due to differences in phenotype. Natural selection is a key mechanism of evolution, the

change in heritable traits of a population of individuals over time. Natural selection works similarly

to artificial selection. Take a dog breeder, for example, who selects only docile dogs to breed. Over

multiple generations, the dogs he breeds will get more and more docile. The major difference between

artificial selection and natural selection is that natural selection does not have a “selector.” Instead,

environmental conditions cause some phenotypes (and consequently, their genotypes) to be able to

survive and reproduce better compared to their competitors. Organisms that are better adapted to

the environment, perhaps through random mutations of their genetic code, are said to have a greater

fitness as they have a greater chance of passing on their genes. Thus, over time, fitness-enhancing

changes in the genotype spread in the next generation. The theory of evolution by natural selection

provides the starting point for evolutionary ethics, as we will see in the next section.

What Should We Do?

When Darwin published The Descent of Man, people immediately began to think about the relations

between his theory of human evolution and ethics. One of the important early proponents of an

ethical theory inspired by evolutionary theory was Herbert Spencer. Spencer, born in 1820 in

7. See Joyce (2016).

8. See Railton (2017).

9. Some evolutionary biologists include these features in what they call the “extended phenotype.” See Dawkins (2016).

78 EVOLUTIONARY ETHICS

England, argued that Darwin’s evolutionary theory would not only explain but also justify moral

behavior. He became known as the foremost defender of the branch of evolutionary ethics that

attempts to deal with answers to the question what we ought to do (more on this below), and he was

a key figure in popularizing Darwin’s ideas in application to the study of ethics. A recollection by

Frederick Pollock, who studied at Cambridge University in England during the height of Spencer’s

popularity, nicely illustrates the enthusiasm with which many adopted the new way of thinking about

ethics:

We seemed to ride triumphant on an ocean of new life and boundless possibilities. Natural Selection was to

be the master-key of the universe; we expected it to solve all riddles and reconcile all contradictions. Among

other things it was to give us a new system of ethics, combining the exactness of the utilitarian with the

poetical ideals of the transcendentalist. We were not only to believe joyfully in the survival of the fittest, but

to take an active and conscious part in making ourselves fitter. (Clifford 1879, 33)

The research program inspired by Spencer provides an important lesson about the pitfalls of

evolutionary ethics. (See the box on Social Darwinism for more details.) Spencer’s followers thought

that evolutionary theory could show that certain moral principles or rules are justified. Recall one of

the core premises in evolutionary theory about the role of individual differences in natural selection.

Fit phenotypes survive and reproduce more or better than unfit phenotypes. For this reason, many

have thought that finding out what is evolutionarily successful shows us what is morally good.

Darwin’s theory has been, mistakenly, taken as a justification for the belief that it is right for the strong

to crowd out the weak and that the only hope for human improvement lays in selective breeding. 10

Social Darwinism

Carrie Buck was a patient in the “Virginia State Colony for Epileptics and Feeble-minded,” as it was called at the

time. Upon a finding that she was “the probable potential parent of socially inadequate offspring, likewise

afflicted, that she may be sexually sterilized without detriment to her general health, and that her welfare and

that of society will be promoted by her sterilization,” the Court ruled that she could be sterilized without her

consent (Buck v. Bell 274, U.S. 200, [1927]). In justifying the ruling, Justice Oliver Wendell Holmes infamously remarked that “three generations of imbeciles are enough” (Doerr 2009).

The court’s ruling cites the common good, and the alleged inability of Carrie Buck to contribute to it, as a

justification for the ruling. Implicitly, the court assumes that “unproductive” people, by whatever measure, have

fewer rights than “productive” people. Such assumptions were at the heart of a great many involuntary eugenics

programs, which aimed at improving the genetic quality of the human population by policing and manipulation

reproduction.

Eugenics programs are expressions of a mistaken, fallacious interpretation of evolutionary theory, which came

to be known as “Social Darwinism.” Eugenics programs were widespread in the early twentieth century, and

many were explicitly based on claims derived from evolutionary theory, such that only the strong should survive

(Paul 2006).

However, such thinking betrays an argumentative fallacy known as an “appeal to nature.” For example,

10. See Paul (2006).

ETHICS 79

arguing that the use of contraceptives is morally wrong because they prevent the “natural” outcome of

intercourse or that men should not do household chores because it is not in their nature are appeals

to nature. Appeals to nature can be fallacious in mistakenly identifying something as “natural”—the

example of men doing household chores illustrates this. Appeals to nature are fallacious in a strict

logical sense, too, because they make an illegitimate step from is to ought. The illegitimacy of deriving

an ought from an is has been emphasized by the Scottish philosopher David Hume, and we can call

the prohibition against doing so Hume’s Law. Hume remarked:

In every system of morality, which I have hitherto met with, I have always remark’d, that the author proceeds

for some time in the ordinary way of reasoning, and establishes the being of a God or makes observations

concerning human affairs; when of a sudden I am surpriz’d to find, that instead of the usual copulations of

propositions, is, and is not, I meet with no proposition that is not connected with an ought, or an ought not.

This change is imperceptible; but is, however, of the last consequence. (Hume [1738] 2007, 302)

Hume deplores the unexplained, imperceptible change from is to ought in a moral argument, and such

imperceptible and illegitimate steps were plentiful in some of the arguments by early proponents of

evolutionary ethics. The problem was that Spencer and his followers sought to derive moral principles

directly from evolutionary insights. The ferocious opposition to Wilson’s suggestion partly reflects the

history of evolutionary ethics, as people feared more crude attempts at deriving an ought from an is.

Historically, the demise of early approaches to evolutionary ethics is most closely associated with

the British philosopher G. E. Moore, who effectively put an end to the heydays of Spencer’s project

in 1903. Moore’s argument provides another instructive objection to evolutionary ethics. Moore

charged Spencer and his followers with committing what he called the “naturalistic fallacy” (Moore

[1903] 1988, 28). Moore was interested in the definition of “good” and argued that since “good” is a

simple property, it cannot be defined by outlining its more basic properties. Thus, identifying “good”

with “higher evolved” as Spencer did was to commit the naturalistic fallacy. The impact of what we

can call “Moore’s Challenge” has been devastating for evolutionary ethics. More than ninety years

after Moore, the philosopher Michael Ruse observes that “it has been enough for the student to

murmur the magical phrase ‘naturalistic fallacy’ and then he or she can move on to the next question,

confident of having gained full marks thus far on the exam” (Ruse 1995, 220).

There is more to be said both about the strength of Hume’s Law and about Moore’s Challenge in

particular. The takeaway at this point is that approaching normative questions about what we ought

to do from within evolutionary ethics requires taking on both challenges. The lessons from the

first century of evolutionary ethics are that the prospects for deriving normative principles from

evolutionary theory are dim.

However, it is important to recognize that evolutionary ethics can still have implications for what

we ought to do by telling us about where moral principles apply. To illustrate the difference between

establishing moral rules and establishing where moral rules apply, consider norms about blame. It is

one thing to establish the moral norm that you are blameworthy if you cause harm or offense when

you could have done otherwise, and quite another to establish, in a specific case, whether Peter is

blameworthy for using foul language that offended some people: after all, he could have Tourette

syndrome, in which case he could not have done otherwise. The project of finding out more about

the features that are relevant for moral evaluation, like our psychology, is thus of crucial importance

80 EVOLUTIONARY ETHICS

for finding out where moral rules apply (so which specific things we ought to do), though it does not

establish the moral rules themselves. It is also a bona fide methodological ethical naturalistic project.

Moreover, evolutionary ethics can be very fruitfully applied to other relevant questions within ethics,

as we will see in the next sections.

Why are We Moral?

Humans are astonishingly prosocial compared to other animals. The primatologist Sarah Hrdy

illustrates this nicely:

Each year 1.6 billion passengers fly to destinations around the world. Patiently we line up to be checked

and patted down by someone we’ve never seen before. We file on board an aluminum cylinder and cram

our bodies into narrow seats, elbow to elbow, accommodating one another for as long as the flight takes.

With nods and resigned smiles, passengers make eye contact and then yield to latecomers pushing past.

When a young man wearing a backpack hits me with it as he reaches up to cram his excess paraphernalia

into an overhead compartment, instead of grimacing or baring my teeth, I smile (weakly), disguising my

irritation….I cannot keep from wondering what would happen if my fellow human passengers suddenly

morphed into another species of ape. What if I were traveling with a planeload of chimpanzees? Any one

of us would be lucky to disembark with all ten fingers and toes still attached, with the baby still breathing

and unmaimed. Bloody earlobes and other appendages would litter the aisles. Compressing so many highly

impulsive strangers into a tight space would be a recipe for mayhem. (Hrdy 2011, 1-4)

What Hrdy is getting at is that humans are a moral species, not in the sense that all of us are morally

good people (some are crooks, after all) but in the sense that normally functioning adults are capable

of following the written and unwritten rules of society so that we can all get along. Importantly, we

sometimes follow such rules even in the absence of credible threats of sanctions: sometimes, people

return that lost wallet of cash, do not cheat even if they could get away with it, and decide to help

people that live in far-away countries. And human children are extraordinarily attuned to attend to

social cues—nothing interests them more than other humans, and they seem to be very concerned

with fairness and other rules that we could classify as moral. But why are we moral? The philosopher

Immanuel Kant famously attributed it to an inborn capacity:

Two things fill the mind with ever new and increasing admiration and reverence, the more often and more

steadily one reflects on them: the starry heavens above me and the moral law within me. (Kant [1788] 2015,

129)

Referring to our moral sense alone, however, does not get us far along to an answer. For why do we

have such a moral sense? After all, it is not only trained moral philosophers that behave respectfully

and non-selfishly on airplanes. Examples of this behavior range from the mundane, such as honest

behavior in circumstances where cheating would be impossible to detect, to the drastic, such as people

that sacrifice their lives for others. How could such behavior have evolved?

Evolutionary ethics in a descriptive sense provides some answers. The hypothesis is that morality is

a tool for cooperation. Being able to follow rules, to internalize them, and to stick to them even if

it is against your immediate interests is what makes morality something that can be useful from an

evolutionary perspective.

There are two competing hypotheses. The first takes a “gene’s eye’s view” on natural selection

ETHICS 81

(Dawkins 2006). According to this view, natural selection occurs only on the level of individual

organisms. Metaphorically speaking, think of your own body, and the traits that make it attractive to

potential mates, as a vehicle for your genes to copy themselves into the next generation. So, to offer an

evolutionary explanation of a certain trait, we have to understand why having that trait would have

led to the organism’s spreading more of its genes into the next generation. At first glance, the gene’s

eye view makes it puzzling why behavior such as sacrifice in war would evolve. After all, how would

sacrificing yourself help you to spread your genes into the next generation? The biologist Richard

Hamilton pointed out that behavior towards our kin would be beneficial even from the perspective

of a selfish gene because we share many genes with our kin (Hamilton 1963). For example, helping

your brother or sister is beneficial from your genes’ point of view, because you share 50% of your

genes with your sibling. Of course, we also behave morally toward people outside our family, and so-

called reciprocal altruism helps explain how such behavior could have evolved (Trivers 1971). Even

though two individuals might be genetically unrelated, it pays for them to benefit the other as long as

the favor is returned in the future so that, over the long run, both organisms enjoy individual fitness

benefits. Therefore, from the gene’s eye view, our beliefs in obligations and duties, our ability to

experience empathy towards others, to understand their intentions, and so forth, is seen as a product

of selective pressures on the individual level.

Proponents of group-selectionist theories take a different perspective on the evolution of morality.

According to this view, natural selection occurs also on the level of groups (as opposed to only on the

level of individual organisms). Group selectionists do not deny the role of selection on the level of

the individual, but they emphasize that group selection is a key ingredient in the evolution of

morality. As competition for resources between groups of hunter-gatherers intensified around

150,000 years ago, group cohesion and cooperation amongst group members became an important

factor. 11

Groups with more cooperative individuals would have a better position in this struggle and,

as we have seen, the ability to follow moral rules would be a way to increase cooperation. As groups

with more cooperative individuals outcompeted groups with less cooperative individuals, the human

population, in general, became more and more attuned to cooperative behavior, and this is why

humans began to develop the moral psychology that characterizes us as moral animals today.

There are still many open questions between these two camps, and many concern the central events,

processes, or mechanisms that enabled the evolution of morality (see the Cultural Evolution box). At

the very least, evolutionary ethics as a descriptive project helps to explain the origins of some of the

foundations of morality.

11. See Tomasello (2016).

82 EVOLUTIONARY ETHICS

Cultural Evolution

Taboos are interestingly similar to moral norms: they are binding and do not allow for exceptions. The

anthropologist John Henrich argues that taboos illustrate how culture played an important role in our

evolutionary history (Henrich 2016). For example, for female inhabitants of Yasawa Island (Fiji) it is taboo to eat

larger fish such as moray eels, barracuda, or sharks when they are pregnant. The taboo is based on tradition and

religious beliefs and adhering to the taboo seems like a significant constraint because the taboo fish make up a

large part of the ordinary diet of most Yasawa islanders, including pregnant women.

Why do pregnant Yasawa women remove such an important source of calories from their diet? The short

answer is that their culturally transmitted beliefs tell them to do so. That they are on the right track can be

understood from the perspective of Western medicine, too. By removing large fish from their menu, pregnant

women run a lower risk of ciguatera poisoning. Ciguatera toxin is produced by a marine microorganism and as it

gets eaten by small fish, and those fish by yet bigger fish, the toxin produced by the microorganism can reach

dangerous levels in large fish like barracuda (Henrich 2016, 128).

Norms about food are transmitted socio-culturally and the anthropologist Joseph Henrich uses the fish-taboo

case to illustrate that culture played a crucial role in the evolution of humans and human morality (Henrich

2016, 100-102). Think of culture as a set of explicit or implicit rules and ways of doing things. Culture in this

sense is intangible and yet part of our tangible environment: if you violate an implicit rule, others might punish

you for it. According to Henrich, “cultural evolution initiated a process of self-domestication, driving genetic

evolution to make us prosocial, docile, rule followers who expect a world governed by social norms monitored

and enforced by communities (Henrich 2016, 5).

Just as culture in the form of, say, taboos about poisonous food can drive genetic evolution, it may constitute an

environment which requires individuals to be attuned to the social rules and thereby favors individuals who are

better able to follow the rules. Culture might thus be an important component in the evolution of morality.

Are there Moral Facts?

So far, we have covered how evolutionary ethics relates to the question what we ought to do and why

we are moral in the first place. A related set of questions about ethics are metaethical questions, which

concern the meaning of moral terms, our ways of gaining knowledge of moral facts, and the nature of

the moral facts. In other words, apart from thinking about how we ought to live, and where our moral

sense comes from, we can also ask what it means to affirm a particular answer to that question, how

we could come to know the answer, and whether the answer would be a matter of fact or more like an

opinion.

Many books and articles in moral philosophy start with the observation that moral judgments seem

to be objectively true and the assumption that this is how non-philosophers also think about

morality. For example, Michael Smith writes:

We seem to think moral questions have correct answers; that the correct answers are made correct by

objective moral facts; that moral facts are wholly determined by circumstances; and that, by engaging in

moral conversation and argument, we can discover what these objective facts are. (Smith 1994, 6)

ETHICS 83

But as we have seen above, evolutionary theory explains why we would think that moral judgments

are objective. The philosopher Michael Ruse takes this to show that the apparent objectivity of

morality is something like an “illusion” foisted on us by our genes (Ruse [1986] 1998, 253). Of course,

even if Ruse is correct, this does not show that moral judgments are not objective, but it can make

us think whether the objectivity of morality really has to be explained, as many philosophers assume.

Ruse has also argued that an evolutionary account of morality suggests that there are no moral facts

in the first place. Anything we want to explain about morality can be explained without mentioning

moral facts, or so Ruse argues. If moral facts are explanatorily redundant, indeed, moral realists (those

who believe there are mind-independent, objective facts about morality, as discussed in Chapter 1)

need to say why we should still suppose that moral facts do exist. Interestingly, Ruse’s methodological

naturalism leads him to embrace a view that goes against the metaphysical naturalist position that

moral facts exist.

Relatedly, Sharon Street, for example, argues that evolutionary explanations of morality show that

moral realism is probably false. The kind of moral realism that Street has in mind is the view

that moral properties exist as objective features of the world (to wit, whether stealing is wrong is

independent of whether anyone thinks or feels that stealing is wrong). Street starts with the premise

that our moral judgments are influenced by evolutionary forces. This fact, Street claims, gives rise

to a dilemma for moral realists concerning the relation of the evolutionary forces that influenced

our moral judgments and the moral facts claimed to exist by moral realists. If there is no relation

between the evolutionary forces and the moral facts, then it would be an astonishing coincidence if

many of our moral judgments were true. In light of the coincidence, we have no reason to assume

that our moral judgments are true—an unpalatable conclusion for realists. Claiming that there is a

relation, however, is empirically dubious, according to Street. Mirroring Ruse’s claim, moral facts

could be purged from what we assume to exist because they do not perform an important explanatory

function. So, we should reject moral realism. Street’s argument illustrates how evolutionary theory

can be used to make a case about which metaethical theories we should adopt.

Both Ruse’s and Street’s arguments rely on the idea that we should only accept that something exists

if it plays an indispensable explanatory role and there are means to resist these arguments. 12

Both

arguments, as presented here, rely on the correctness of the evolutionary explanation of morality they

convey. In the next section, we turn to the relevance of evolutionary ethics for moral epistemology.

Can We have Justified Moral Beliefs?

The evolutionary argument by Sharon Street can also be interpreted as an argument about moral

justification and moral knowledge. Suppose that moral realists assume that there is no relation

between our moral judgments and the moral facts. It would seem like an incredible coincidence if the

realists were right that our moral judgments are nonetheless true. There are just too many possible

moral truths and too many ways in which evolution could have “pushed” our moral beliefs. Street

claims that such a coincidence would be too much to believe. But what is the problem, exactly, with

having beliefs that are only coincidentally true? Depending on how we understand “coincidence,” my

belief that there is a bird outside my window is coincidentally true because had I looked a little later,

the bird would have flown away already. Accidentally true beliefs do not seem problematic in every

12. E.g. Enoch (2010)

84 EVOLUTIONARY ETHICS

case. The question for proponents of Street’s argument is to show why the evolutionary influence on

human moral beliefs makes for a particularly problematic case of coincidence.

The philosopher Richard Joyce argues that the problem has to do with the sensitivity of our moral

beliefs to the moral facts ( Joyce 2006). Given that our moral beliefs are influenced by evolutionary

forces, and not by the moral facts, our moral beliefs would be the same even if the moral facts would

change. But because we should not hold on to such insensitive beliefs, evolutionary explanations of

morality show that our moral beliefs are unjustified (because they are not sensitive).

It is not clear, however, whether and why evolutionary explanations of morality reveal something

about our moral beliefs that is particularly troubling from an epistemological perspective. The impact

of evolutionary ethics on epistemological questions depends on these deeper questions about

epistemology. 13

Evolutionary explanations of morality, however, provide us with a useful starting

point for thinking about these questions.

C O N C L U S I O N

Evolutionary ethics has helped us to get a much clearer sense of where the human moral sense

is coming from. While this is a far cry from revealing to us what we ought to do, the research

program seems full of promise nonetheless. Once we get into the details, we can see that it also raises

deep theoretical questions about evolutionary explanations, the relation of descriptive and normative

claims, the epistemology of justification and truth, and the general viability of naturalism in ethics.

Much left to wonder, then, but with some ideas about where to get our answers.

R E V I E W S TAT E M E N T

Introduction to Philosophy: Ethics, part of the Introduction to Philosophy series, was produced with support

from the Rebus Community, a non-profit organisation building a new, collaborative model for

publishing open textbooks. Critical to the success of this approach is including mechanisms to ensure

that open textbooks produced with the Community are high quality, and meet the needs of all

students who will one day use them. Rebus books undergo both peer review from faculty subject

matter experts and beta testing in classrooms, where student and instructor feedback is collected.

This book has been peer reviewed by two subject experts. The full-text received an open review from

the reviewers, based on their area of expertise.

The review was structured around considerations of the intended audience of the book, and examined

the comprehensiveness, accuracy, and relevance of content, as well as longevity and cultural

relevance. Further review by the series editor and the copy editor focused on clarity, consistency,

organization structure flow, and grammatical errors. See the review guide for more details. Changes

suggested by the reviewers were incorporated by chapter authors and the book editor.

George Matthews (book editor), Christina Hendricks (series editor) and authors Frank Aragbonfoh

Abumere, Douglas Giles, Ya-Yun Kao, Michael Klenk, Joseph Kranak, Kathryn MacKay, Jeff Morgan,

Paul Rezkalla, and the team at Rebus would like to thank the reviewers for the time, care, and

commitment they contributed to the project. We recognise that peer reviewing is a generous act of

service on their part. This book would not be the robust, valuable resource that it is were it not for

their feedback and input.

We are working to create a new, collaborative model for publishing open textbooks. Critical to our

success in reaching this goal is to ensure that all books produced using that model meet the needs of

all students who will one day use them. To us, open means inclusive, so for a book to be open, it must

also be accessible.

As a result, we are working with accessibility experts and others in the OER community to develop

best practices for creating accessible open textbooks, and are building those practices into the Rebus

model of publishing. By doing this, we hope to ensure that all books produced using the Rebus

Community are accessible by default, and require an absolute minimum of remediation or adaptation

to meet any individual student’s needs.

While we work on developing guidelines and implementing support for authoring accessible content,

we are making a good faith effort to ensure that books produced with our support meet accessibility

standards wherever possible, and to highlight areas where we know there is work to do. It is our hope

that by being transparent on our current books, we can begin the process of making sure accessibility

is top of mind for all authors, adopters, students and contributors of all kinds on all our open textbook

projects.

Below is a short assessment of eight key areas that have been assessed during the production process.

The checklist has been drawn from the BCcampus Open Education Accessibility Toolkit. While a

checklist such as this is just one part of a holistic approach to accessibility, it is one way to begin our

work on embedded good accessibility practices in the books we support.

Wherever possible, we have identified ways in which anyone may contribute their expertise to

improve the accessibility of this text.

We also welcome any feedback from students, instructors or others who encounter the book and

identify an issue that needs resolving. This book is an ongoing project and will be updated as needed.

Philosophy series accessibility suggestions form.
