Introduction
In the book, “After the Natural Law”, Hill aligns the development of philosophy from the
classical philosophical approaches to modern beliefs. Hill uses multiple philosophers throughout
all times to develop the path from classical to modern philosophy. The book displays the works,
theories, and beliefs of philosophers such as Aristotle, Plato, Aquinas, Augustine, Luther,
Hooker, and Calvin and how we have built up the way that we view natural law today. These
philosophers have been instrumental in the development of natural law throughout centuries.
According to the book, it is implied that natural law is something that comes naturally to people
and this understanding and its impact on society has been examined carefully throughout (Hill, J.
L. (2016)). Hill ensures to cover some of the major critics and problems with the critics
pertaining to natural law. It is essential to understand that Hill opined that without natural law
ethics would turn to chaos. Hill explained that when man starts ignoring and denying the
existence of natural law and rights the universe will become meaningless (Hill, J. L. (2016)). The
author explains in the book how we as a society are now in the aftermath of natural law and that
we are essentially centered by specific cultures we have deemed important to us and natural law
becomes forgotten, dismissed, or denied. The importance of positive law and government can be
seen to easily undermine the principles of natural law making natural law a threat to positive law.
The threat exists as positive laws are formed by the government to determine people's rights and
oversee people’s natural rights. He valued the main political and moral values of freedom, moral
truth, responsibility, and human dignity as he explains in detail within the book to help readers
understand the classical ways of the universe. He continues to explain how natural law shapes
other concepts of democracy, statesmanship, and positive law. Throughout the book, we will see
that natural law creates a moral framework and allows us to have purposeful and just lives.
Natural Law
Natural Law is a concept that creates a focal point of postulation regarding morality and
politics in Western traditions. There are a variety of definitions concerning what natural law
theory ought to be. Despite the multiple definitions, philosophers have agreed that it is an
interflow of both moral and legal philosophy. This agreement between different philosophers
shows that both theories hold importance over our ethics in human behaviors. Through natural
law, we acknowledge what are the legal and moral concepts of human rights and how society
ought to live. Throughout life, mankind must follow standards to keep a just life and many
philosophers feel that these natural laws are inherent in the nature of man. Natural law is not
fixed to a single theoretic belief on natural law however; it is continuously built and reinterpreted
by many philosophers including but not limited to: Aquinas, Locke, Aristotle, Luther, and
Lincoln.
Plato was the first philosopher to insinuate some thought theory of natural law however it
was never fully delved into. Since Plato never exemplified natural law, Aristotle, who was
Plato’s student has been considered the first philosopher to establish natural law (Aristotle, A (-
320). Hill determines Aquinas to be one of the greatest philosophers of natural law as he
perceived natural law as being something we have been born with. Aquinas believed that a
perfect natural law would be knowing what is right and avoiding what is wrong. He believed that
everybody had synderesis and that natural inclinations that are good were what made mankind
happy (Aquinas, T. (1981)). Contrarily, Locke regarded natural law as something built outside of
God and stated it was an imposed theory. Locke was unable to see that humans had a conscience
naturally built-in into their minds (Locke’s Political Philosophy (Stanford Encyclopedia of
Philosophy). (2020, October 6)). Hobbes, another philosopher, regarded human nature instead of
natural law and stated that since humans are selfish in nature that human nature can be disastrous
(Hobbes’s Moral and Political Philosophy (Stanford Encyclopedia of Philosophy). (2022,
September 12)). Luther and Hooker wanted to preserve Christian society and covenantal
statesmanship. These philosophers instilled the belief that humans created positive laws based on
the good morality of natural laws. Natural law is coextensive with legal law. Morality helps men
know the difference between just and unjust while law focuses on man-made laws established
and maintained by governments. Where natural law is objective and universal, positive law is
ever-changing based on political order.
Abraham Lincoln stated, “Government of the people, by the people, for the people” and
meticulously defined democracy of natural law through this statement. Natural law democracy is
formed by the state as a moral responsibility to protect and respect the rights of humans.
Statesmanship relies on making every just and unjust right equal to every individual within a
nation. Natural law and positive law do threaten each other as natural law is said to be inherited
in every individual through what is written on our hearts however; positive law is what
governments determine what is the legal rights of man. Positive law is formed to ensure the
management of a human’s natural rights. The colossal discrepancy between natural law in
modern times compared to that of classical times is that classical natural law depended on nature
of reality, element of a person and the final end whereas, the modern views of natural law theory
have been skeptical of metaphysics and denied these philosophical approaches. Instead the
modern views outlined basic goods that we instinctively know and act upon. Denial of
metaphysics is what led to the decline and abandonment of natural law.
Review
Hill recognizes that the concept of natural law is imperative for us to understand
to ensure the health of our evolving and dynamic society. He follows the belief that natural law
becomes a workable system due to the religious and Christian beliefs of natural law. Through the
review, we will see how the author followed the development of Western philosophy from
classical to modern times. Hill presupposed that without political and moral values of freedom,
dignity, truth, or responsibility we will not have an interpretation of how the classical world
formed and worked. The author does follow some philosophical theories that people may not
have the ability to understand the deepest values if that person does not believe in God’s moral
and human truth (Hill, J. L. (2016)).
In Part 1, the author expounds on how natural law originated within the philosophical
history of Aristotelian and Platonic teleology and how natural law theories challenge the ideas of
materialistic views. Much like Aristotle, Hill concluded that man was able to attain true
happiness and purity by following their innate nature (Hill, J. L. (2016)). Meaning that nature
infers that man is born knowing right from wrong and in following this nature they could achieve
beatitude. With Aristotle's belief in natural law, it is suggested that if leaders follow their inherent
nature they would not need to enforce rules or punishment. Hill shares his views of natural
justice and natural law working together to form political justice in society. He extends this view
by explaining developments from natural law in Stoics and Aquinas's times. The author sees the
truth in the beliefs of Aristotle however; feels that he had failed to mention the Almighty creator
of the natural laws. Hill finds this detail within Aquinas's philosophical theory regarding natural
laws where Aquinas establishes that God is the meaning being all throughout the existence of
time and space (Hill, J. L. (2016)). Aquinas worked to link philosophy and religion in the book
Summa Theologiae. In this book, Aquinas opines that although we might not need both religion
and philosophy to link we can see that theology can accept thoughts from philosophical
approaches. The legal laws written out within the Summa Theologia were proclaimed by humans
to collaborate and create stability, workability, and general principles (Aquinas, T. (1981)). Hill
writes that Aquinas suggests positive law is man-made rules set by free people to govern them.
The author suggests that with this Aquinas split the whole into half to explain not only the
positive law but also the natural law and how each law can work together in society to govern the
people and ensure just societies. Augustine was another philosopher that contributed to natural
law. His best interpretation of natural law can be epitomized by stating that unjust law can’t be a
law at all, for if norms do not comply with natural law then natural law would not be able to be
validated (Chroust, A.H. (1944)). Hill understood that Augustine saw natural law as more than an
act of free will. Augustine stated that natural law was a mixture of many things stemming from
God which could be law, order, flow, and logic. Augustine also split law into two forms both of
which are governed by man- these two laws include the natural law which is inherited in man by
God and the other external law made by man to ensure enforcement of natural law. As we can
see the classical philosophers of this time believed that we can’t know the existence of something
without understanding its purpose (Chroust, A.H. (1944)).
After classical natural law theorists, we have moral voluntarism theorists such as
Ockham, Calvin, and Locke. These theorists defined moral voluntarism as moral standards that
could not be fixed meaning that God could change his mind at any time. It was assumed that we
know right from wrong because we know God’s will. Contrary to moral voluntarism is moral
rationalism. In Plato’s philosophy in Euthyphro, we can see that Plato’s beliefs are more aligned
with the moral rationalist. Moral rationalism is knowing what is just and unjust due to the nature
of the acts and not because God will (Hill, J. L. (2016)).
In Part 2, Hill analyzes the negative impacts that the denial of natural law has had on
today’s society along with the failures of understanding the world from a classical viewpoint.
The author uses the philosophical views of Descartes, Hobbes, Locke, Kant, Luther, and Calvin
to explain the path of natural law from classical to modern times. The views also show how we
eventually disassemble beliefs of the natural law. Luther’s viewpoints state that social behavior
should be evaluated for human nature to understand natural law. He states that even without the
ten commandments we would still be governed by the same natural laws (Luther, M. (1523)).
Calvin also holds similar viewpoints and does not see the alignment between human reason and
the natural law. Calvin much like Luther states that even without the biblical injunctions and
divine positive law we would still hold law (Pryor, C. S. (2006)). Romans 2:14-14, “For when
Gentiles, who do not have the law, by nature do the things in the law, those, although not having
the law, are a law to themselves, who show the work of the law written in their hearts, their
conscience also bearing witness, and between themselves, their thoughts accusing or else
excusing (them)” (Romans 2:14-15, NKJV (n.d)). Relating Calvin and the passage from the New
King James Version we can refer to this as the knowledge of natural law possessed by the
Gentiles even with the absence of divine law. Ockham, known as the father of modern
nominalism, had one of the biggest consequences of theological and metaphysical theories.
Ockham denied that there was human nature and in return made it different to understand man’s
common end. Due to their being no human nature, there is no human end. Ockham believed that
what made an act good was the way that it conformed to the will of God (Hill, J. L. (2016)). The
major dilemma with this is that we focus more on the will of God and less on the morality of our
nature. This becomes a problem when we push so much that moral voluntarism erases reason and
synderesis. Descartes, a modern philosopher also referred to as the father of modern rationalism
essentially took the work of both Aristotle and St. Thomas and flipped it. He tried to understand
the relationship between metaphysics and epistemology opposite of the way it was understood in
classical philosophy. Under Descartes's approach, we must understand how we know something
before we can understand what we know of that something. It was Descartes who brought back
the old determinism of the world but he also accepted that the old determinism clashed with free
will. His solution to this clash was dualism- to divide the world into the material world (res
extensa and the free-thinking mind (res cogitans) (Hill, J. L. (2016)).
Public Policy Applications
Abortion has always been a controversial topic in political rights and natural law. Even
today we still argue whether it is just or unjust to allow abortions. In the Summa Theologiae,
Aquinas wrote about the life principle related to natural law. The life principle states that all
beings remain in existence. It is natural for humans and animals alike to care for their offspring
however; how we can care for an offspring often depends on external environmental factors,
ideas, and beliefs. According to the principle and natural law of life, it would seem contrary to
nature to exterminate a fetus intentionally however; it can also be said in contrary that if it
threatens the life of a mother then there is a conflict between the two rights of life. This conflict
of rights leads us to question that if we recognize the right of life to the human fetus we could
infringe on the rights of the mothers to voluntarily have children. In contrast, Christian natural
law principles may still take precedence over the conflict of rights. For instance, a woman who
continues a pregnancy to bring life regardless of her own outcome would be seen as heroic as she
has placed a life before her own (Kainz, H. (2022, October 26).
Free market economics also known as supply and demand was originally implied by John
Locke. Locke elaborated on individual liberty and stated that because it was not a democracy that
it would be against natural law for any person to control your liberty, income, or property. The
second treatise of government also aligns with this message by stating “Man being born…
enjoyment of all rights and privileges of the law of nature… hath by nature a power, not only to
preserve his property…”. According to Locke, private property and free economics was based on
natural law. Regarding supply and demand, Locke did not coin this term and very vaguely
implied the theory. According to the theory that is present Locke states, “The price of any
commodity rises or falls by the proportion of the number of buyers and sellers” (John Locke
Economic Theory – Political Economy. (n.d.). Even today, we continue to see the inflation of
pricing, however; we are seeing this in a wide variety of things as humans tend to have more
desires and needs.
We have to take a dual approach when relating Education policy to natural law. This dual
approach examines education policy through both philosophical issues and educational practice.
Plato in the Republic, attempts to create a vision of education through sorting people regarding
their abilities and interest in life. It continues to Rousseau, who was insistent on having a natural
and free development of children instead of a formal education. The beliefs of Rousseau, were
much like a progressivism movement and leads us to the input that Dewey had on Education.
Dewey had a huge impact on education in which he raised concerns about gender, growth,
problems, student’s interest, appropriate activities, and it being child centered. In today’s society
we see that all educational activities, curriculum, policy and classroom practice stem from the
assumptions from multiple philosophers throughout time (Philosophy of education | History,
Problems, Issues, & Tasks. (1999, July 26).
Conclusion
In conclusion, Hill believes that every human has free will however; recognizes that as
much as they have free will they have the choice to deviate from natural law. The author does
excellent work in recognizing how our modern morals and political views are founded upon
classical worldviews. Hill starts the book by introducing some important philosophers in the rise
of natural law and also some important modern theorists where we start to see the decline in
natural law. Descartes was one of the early contemporary theorists who influenced the decline in
natural law by his approach to cartesian dualism. The twenty-first century brought about
skepticism, materialism, and other flawed theories through the growth of Kantianism and
Utilitarianism. Kantianism and Utilitarianism diluted Christianity into deism and changed the
way we view natural law. Even today this threat continues to spread as we look through the
views of Atheism. Reflecting on the changes throughout society we can see that the further we
veer away from natural law the more likely that we are headed into a societal crisis as with the
lack of natural law there is a lack of reason or teleology. Although Hill's book does show the
great decline in natural law views in today’s society he still continues to have an encouraging
approach that natural law may not be denied fully. He continues to feel that natural law is an
important concept to philosophical principles of all natural law and should be used in all
defenses against those who attempt to say otherwise.
