Substance and essence: examining metaphysical theories
on the nature of substance and the essential properties of
objects
Introduction
Questions concerning the nature of substance and essence have been
central to metaphysical inquiry since ancient times. Philosophers have long
pondered such issues as: What is the fundamental entity or substrate that
ultimately composes objects in the world? What features are essential versus
accidental to their identity and character? Differentiating substance from
accidental attributes constitutes a basic problem for ontology.
This essay will examine differing perspectives that have emerged historically
on the notion of substance and essence. It will outline the classical
metaphysical theories proposed by ancient philosophers like Aristotle as well
as more modern ideas. Key distinctions will be drawn between substance and
attribute, essential and accidental properties. The essay will also consider
debates around issues such as universalism versus nominalism regarding
essential natures. Overall, exploring alternative stances on substance and
essence illuminates enduring investigations into fundamental concepts
underlying theories of reality.
Substance Theory in Ancient Philosophy
Some of the earliest comprehensive treatments of substance and essence
were put forth by pre-Socratic and Aristotelian philosophers in ancient
Greece. Pythagoreans and Heraclitus conceived of basic entities changing
through alternating contrarieties as the ultimate substrates of phenomena.
Democritus posited atoms as indivisible, continuously existent substances
capable of diverse combinations (Shields, 2016).
However, Aristotle developed the most influential and systematic classical
theory. In his Metaphysics, Aristotle defines substance (ousia) as the basic
particular entity which underlies all other attributes. Its essence (to ti ên
einai) is that which makes it the kind of thing it is and distinguishes it from
other categories (Aristotle, 1999).
For Aristotle, substances are primary beings that exist in their own right as
individual hylomorphic composites of matter and form. Their essences
constitute the set of properties eternally belonging to the natural kind
without which they could not persist as that kind of entity. By contrast,
attributes like size or location are non-essential or accidental, changeable
properties of substance (Lloyd, 1981).
Aristotle's idea of substance as the ultimate subject of predication capable of
independent existence addressed Parmenidean worries over change by
distinguishing essence from accident. However, questions remained
regarding the ontological status of Platonic Forms and relations between
kinds/attributes/individuals in his system (Code, 1986). His essentialism also
faced challenges explaining accidental features within a deterministic
framework.
Cartesian Substance Dualism
A major development came with René Descartes' 17th century formulation of
substance dualism. For Descartes, ‘substance’ denotes that which requires
nothing else for its existence, possessing either thought (res cogitans) or
extension (res extensa) as its essence. Examining phenomena through
systematic doubt, he saw thinking and physical extension as fundamentally
different kinds of attributes defining the essential natures of distinct mental
and material substances (Descartes, 1989).
Descartes’ conception of self-sufficient thinking substance invoked in his
famous “I think, therefore I am” line marked a radical departure from
Aristotelian hylomorphism. It separated mind and body into fundamentally
heterogeneous ontological categories (Descartes, 1984). However, questions
remained regarding causal interaction between immaterial thinking and
material extended substances in his system. Substance dualism also
struggled to coherently account for conjoined mind-body phenomena (Kim,
1998).
Bundle Theory and Empiricism
In reaction to views positing mysterious indivisible substances, empiricist
philosophies proposed alternative conceptions. Hume essentially denied the
existence of substantive minds or objects, reducing them to “bundles” of
momentary perceptions associated through resemblance and causation
(Hume, 1957). For Hume, there are only attribute impressions without
intrinsic essences or substantial beings to bear them.
Berkeley similarly denied existence of independent material substance,
arguing only for finite minds and their ideas as knowable entities. Under
empiricism, attributes constituted the primary contents of experience rather
than manifestations of deeper essences inhering in substances (Berkeley,
1991). However, empiricist accounts struggled to explain cohesion, identity
or external reference if attributes alone comprised reality.
Nominal Essentialism and Natural Kinds
Recent philosophers have advocated revised forms of Aristotelian-style
essentialism integrating natural scientific perspectives. Hilary Putnam’s
internal realism (Putnam, 1982) and Saul Kripke’s arguments around natural
kind terms (Kripke, 1980) suggest essential properties linked to historical
origins rather than intrinsic natures.
On this view, natural kinds like water or gold indirectly denote clusters of co-
instantiated properties emerging from causal histories rather than intrinsic
Platonic essences identifiable a priori. Although essences cannot be directly
intuited, natural kind membership involves essential properties determined
by historical relationships. However, questions remain regarding how
historical dependencies ground strict essences as demanded by essentialism
(Bielskis, 2018).
Process Philosophies and Relational Ontology
Departing from any notion of independently existing substances, process
philosophies like those of Alfred North Whitehead emphasize relationship and
temporal becoming over static essences (Whitehead, 1978). For Whitehead,
fundamental reality comprises occasions of experience (“actual entities”)
that emerge from and influence one another according to creative processes
of concrescence.
Contemporary relational ontology further develops such perspectives,
opposing reified substances/essences in favor of inherently relational
networks comprising events, fields, dispositions and regularities between
dynamic entities (DeLanda, 2006). However, while capturing flux and
emergence, these stances potentially sacrifice identity conditions for things
and universality undermining robust theorizing.
Object-Oriented Ontology
A more moderate approach combining essentialist and relational elements is
found in influential object-oriented ontologies like those of Graham Harman
(Harman, 2018). For Harman, objects possess unique irreducible profiles
distinct from relations yet manifested through them. Objects’ qualities
persist even when relations change, indicating essences beyond correlations
alone.
At the same time, objects always exceed full relations and withdrawal from
full characterization, avoiding intrinsic reification. On this view, objects
comprise dynamic hubs of qualities and capacities with boundaries that
enable but transcend interactions (Morton, 2013). This grants a measure of
independence yet interconnectivity, addressing worries faced by strict
essentialism or flux-only philosophies. However, skeptics argue object
profiles remain fundamentally inaccessible or incoherent.
Concluding Reflections
In closing, surveying metaphysical theories of substance, essence and
properties demonstrates the richness yet complexity of these enduring
problems. Ancient and modern philosophers have proposed diverse
perspectives, from hylomorphic substances and Cartesian dualism to
empiricist bundles, natural kinds and process thought.
Contemporary views offer novel syntheses, with nominal essences emerging
through relations yet objects retaining independence. However, key issues
persist, such as grounding: coherence between independent
essences/objects and relational manifestations; explanation of phenomena
like attributes, change or causal interaction; and epistemological access to
essences.
Overall, philosophizing on these topics reveals metaphysics as an evolving
intergenerational inquiry, with alternative positions continually critiqued and
refined but no consensus attained. Exploring diverse frameworks proves
illuminating even without settlement, as fundamental yet elusive notions
demand ongoing principled yet flexible examination. Questions of substance,
essence and property underlie all ontology and continue stimulating probing
philosophical theorizing.

full characterization, avoiding intrinsic reification. On this view, objects
comprise dynamic hubs of qualities and capacities with boundaries that
enable but transcend interactions (Morton, 2013). This grants a measure of
independence yet interconnectivity, addressing worries faced by strict
essentialism or flux-only philosophies. However, skeptics argue object
profiles remain fundamentally inaccessible or incoherent.
Concluding Reflections
In closing, surveying metaphysical theories of substance, essence and
properties demonstrates the richness yet complexity of these enduring
problems. Ancient and modern philosophers have proposed diverse
perspectives, from hylomorphic substances and Cartesian dualism to
empiricist bundles, natural kinds and process thought.
Contemporary views offer novel syntheses, with nominal essences emerging
through relations yet objects retaining independence. However, key issues
persist, such as grounding: coherence between independent
essences/objects and relational manifestations; explanation of phenomena
like attributes, change or causal interaction; and epistemological access to
essences.
Overall, philosophizing on these topics reveals metaphysics as an evolving
intergenerational inquiry, with alternative positions continually critiqued and
refined but no consensus attained. Exploring diverse frameworks proves
illuminating even without settlement, as fundamental yet elusive notions
demand ongoing principled yet flexible examination. Questions of substance,
essence and property underlie all ontology and continue stimulating probing
philosophical theorizing.
Questions concerning the nature of substance and essence have been
central to metaphysical inquiry since ancient times. Philosophers have long
pondered such issues as: What is the fundamental entity or substrate that
ultimately composes objects in the world? What features are essential versus
accidental to their identity and character? Differentiating substance from
accidental attributes constitutes a basic problem for ontology.
This essay will examine differing perspectives that have emerged historically
on the notion of substance and essence. It will outline the classical
metaphysical theories proposed by ancient philosophers like Aristotle as well
as more modern ideas. Key distinctions will be drawn between substance and
attribute, essential and accidental properties. The essay will also consider
debates around issues such as universalism versus nominalism regarding
essential natures. Overall, exploring alternative stances on substance and
essence illuminates enduring investigations into fundamental concepts
underlying theories of reality.
Substance Theory in Ancient Philosophy
Some of the earliest comprehensive treatments of substance and essence
were put forth by pre-Socratic and Aristotelian philosophers in ancient
Greece. Pythagoreans and Heraclitus conceived of basic entities changing
through alternating contrarieties as the ultimate substrates of phenomena.
Democritus posited atoms as indivisible, continuously existent substances
capable of diverse combinations (Shields, 2016).
However, Aristotle developed the most influential and systematic classical
theory. In his Metaphysics, Aristotle defines substance (ousia) as the basic
particular entity which underlies all other attributes. Its essence (to ti ên
einai) is that which makes it the kind of thing it is and distinguishes it from
other categories (Aristotle, 1999).
For Aristotle, substances are primary beings that exist in their own right as
individual hylomorphic composites of matter and form. Their essences
constitute the set of properties eternally belonging to the natural kind
without which they could not persist as that kind of entity. By contrast,
attributes like size or location are non-essential or accidental, changeable
properties of substance (Lloyd, 1981).
Aristotle's idea of substance as the ultimate subject of predication capable of
independent existence addressed Parmenidean worries over change by
distinguishing essence from accident. However, questions remained
regarding the ontological status of Platonic Forms and relations between
kinds/attributes/individuals in his system (Code, 1986). His essentialism also
faced challenges explaining accidental features within a deterministic
framework.
Cartesian Substance Dualism
A major development came with René Descartes' 17th century formulation of
substance dualism. For Descartes, ‘substance’ denotes that which requires
nothing else for its existence, possessing either thought (res cogitans) or
extension (res extensa) as its essence. Examining phenomena through
systematic doubt, he saw thinking and physical extension as fundamentally
different kinds of attributes defining the essential natures of distinct mental
and material substances (Descartes, 1989).
Descartes’ conception of self-sufficient thinking substance invoked in his
famous “I think, therefore I am” line marked a radical departure from
Aristotelian hylomorphism. It separated mind and body into fundamentally
heterogeneous ontological categories (Descartes, 1984). However, questions
remained regarding causal interaction between immaterial thinking and
material extended substances in his system. Substance dualism also
struggled to coherently account for conjoined mind-body phenomena (Kim,
1998).
Bundle Theory and Empiricism
In reaction to views positing mysterious indivisible substances, empiricist
philosophies proposed alternative conceptions. Hume essentially denied the
existence of substantive minds or objects, reducing them to “bundles” of
momentary perceptions associated through resemblance and causation
(Hume, 1957). For Hume, there are only attribute impressions without
intrinsic essences or substantial beings to bear them.
Berkeley similarly denied existence of independent material substance,
arguing only for finite minds and their ideas as knowable entities. Under
empiricism, attributes constituted the primary contents of experience rather
than manifestations of deeper essences inhering in substances (Berkeley,
1991). However, empiricist accounts struggled to explain cohesion, identity
or external reference if attributes alone comprised reality.
Nominal Essentialism and Natural Kinds
Recent philosophers have advocated revised forms of Aristotelian-style
essentialism integrating natural scientific perspectives. Hilary Putnam’s
internal realism (Putnam, 1982) and Saul Kripke’s arguments around natural
kind terms (Kripke, 1980) suggest essential properties linked to historical
origins rather than intrinsic natures.
On this view, natural kinds like water or gold indirectly denote clusters of co-
instantiated properties emerging from causal histories rather than intrinsic
Platonic essences identifiable a priori. Although essences cannot be directly
intuited, natural kind membership involves essential properties determined
by historical relationships. However, questions remain regarding how
historical dependencies ground strict essences as demanded by essentialism
(Bielskis, 2018).
Process Philosophies and Relational Ontology
Departing from any notion of independently existing substances, process
philosophies like those of Alfred North Whitehead emphasize relationship and
temporal becoming over static essences (Whitehead, 1978). For Whitehead,
fundamental reality comprises occasions of experience (“actual entities”)
that emerge from and influence one another according to creative processes
of concrescence.
Contemporary relational ontology further develops such perspectives,
opposing reified substances/essences in favor of inherently relational
networks comprising events, fields, dispositions and regularities between
dynamic entities (DeLanda, 2006). However, while capturing flux and
emergence, these stances potentially sacrifice identity conditions for things
and universality undermining robust theorizing.
Object-Oriented Ontology
A more moderate approach combining essentialist and relational elements is
found in influential object-oriented ontologies like those of Graham Harman
(Harman, 2018). For Harman, objects possess unique irreducible profiles
distinct from relations yet manifested through them. Objects’ qualities
persist even when relations change, indicating essences beyond correlations
alone.
At the same time, objects always exceed full relations and withdrawal from
full characterization, avoiding intrinsic reification. On this view, objects
comprise dynamic hubs of qualities and capacities with boundaries that
enable but transcend interactions (Morton, 2013). This grants a measure of
independence yet interconnectivity, addressing worries faced by strict
essentialism or flux-only philosophies. However, skeptics argue object

by historical relationships. However, questions remain regarding how
historical dependencies ground strict essences as demanded by essentialism
(Bielskis, 2018).
Process Philosophies and Relational Ontology
Departing from any notion of independently existing substances, process
philosophies like those of Alfred North Whitehead emphasize relationship and
temporal becoming over static essences (Whitehead, 1978). For Whitehead,
fundamental reality comprises occasions of experience (“actual entities”)
that emerge from and influence one another according to creative processes
of concrescence.
Contemporary relational ontology further develops such perspectives,
opposing reified substances/essences in favor of inherently relational
networks comprising events, fields, dispositions and regularities between
dynamic entities (DeLanda, 2006). However, while capturing flux and
emergence, these stances potentially sacrifice identity conditions for things
and universality undermining robust theorizing.
Object-Oriented Ontology
A more moderate approach combining essentialist and relational elements is
found in influential object-oriented ontologies like those of Graham Harman
(Harman, 2018). For Harman, objects possess unique irreducible profiles
distinct from relations yet manifested through them. Objects’ qualities
persist even when relations change, indicating essences beyond correlations
alone.
At the same time, objects always exceed full relations and withdrawal from
full characterization, avoiding intrinsic reification. On this view, objects
comprise dynamic hubs of qualities and capacities with boundaries that
enable but transcend interactions (Morton, 2013). This grants a measure of
independence yet interconnectivity, addressing worries faced by strict
essentialism or flux-only philosophies. However, skeptics argue object
profiles remain fundamentally inaccessible or incoherent.
Concluding Reflections
In closing, surveying metaphysical theories of substance, essence and
properties demonstrates the richness yet complexity of these enduring
problems. Ancient and modern philosophers have proposed diverse
perspectives, from hylomorphic substances and Cartesian dualism to
empiricist bundles, natural kinds and process thought.
Contemporary views offer novel syntheses, with nominal essences emerging
through relations yet objects retaining independence. However, key issues
persist, such as grounding: coherence between independent
essences/objects and relational manifestations; explanation of phenomena
like attributes, change or causal interaction; and epistemological access to
essences.
Overall, philosophizing on these topics reveals metaphysics as an evolving
intergenerational inquiry, with alternative positions continually critiqued and
refined but no consensus attained. Exploring diverse frameworks proves
illuminating even without settlement, as fundamental yet elusive notions
demand ongoing principled yet flexible examination. Questions of substance,
essence and property underlie all ontology and continue stimulating probing
philosophical theorizing.
Questions concerning the nature of substance and essence have been
central to metaphysical inquiry since ancient times. Philosophers have long
pondered such issues as: What is the fundamental entity or substrate that
ultimately composes objects in the world? What features are essential versus
accidental to their identity and character? Differentiating substance from
accidental attributes constitutes a basic problem for ontology.
This essay will examine differing perspectives that have emerged historically
on the notion of substance and essence. It will outline the classical
metaphysical theories proposed by ancient philosophers like Aristotle as well
as more modern ideas. Key distinctions will be drawn between substance and
attribute, essential and accidental properties. The essay will also consider
debates around issues such as universalism versus nominalism regarding
essential natures. Overall, exploring alternative stances on substance and
essence illuminates enduring investigations into fundamental concepts
underlying theories of reality.
Substance Theory in Ancient Philosophy
Some of the earliest comprehensive treatments of substance and essence
were put forth by pre-Socratic and Aristotelian philosophers in ancient
Greece. Pythagoreans and Heraclitus conceived of basic entities changing
through alternating contrarieties as the ultimate substrates of phenomena.
Democritus posited atoms as indivisible, continuously existent substances
capable of diverse combinations (Shields, 2016).
However, Aristotle developed the most influential and systematic classical
theory. In his Metaphysics, Aristotle defines substance (ousia) as the basic
particular entity which underlies all other attributes. Its essence (to ti ên
einai) is that which makes it the kind of thing it is and distinguishes it from
other categories (Aristotle, 1999).
For Aristotle, substances are primary beings that exist in their own right as
individual hylomorphic composites of matter and form. Their essences
constitute the set of properties eternally belonging to the natural kind
without which they could not persist as that kind of entity. By contrast,
attributes like size or location are non-essential or accidental, changeable
properties of substance (Lloyd, 1981).
Aristotle's idea of substance as the ultimate subject of predication capable of
independent existence addressed Parmenidean worries over change by
distinguishing essence from accident. However, questions remained
regarding the ontological status of Platonic Forms and relations between
kinds/attributes/individuals in his system (Code, 1986). His essentialism also
faced challenges explaining accidental features within a deterministic
framework.
Cartesian Substance Dualism
A major development came with René Descartes' 17th century formulation of
substance dualism. For Descartes, ‘substance’ denotes that which requires
nothing else for its existence, possessing either thought (res cogitans) or
extension (res extensa) as its essence. Examining phenomena through
systematic doubt, he saw thinking and physical extension as fundamentally
different kinds of attributes defining the essential natures of distinct mental
and material substances (Descartes, 1989).
Descartes’ conception of self-sufficient thinking substance invoked in his
famous “I think, therefore I am” line marked a radical departure from
Aristotelian hylomorphism. It separated mind and body into fundamentally
heterogeneous ontological categories (Descartes, 1984). However, questions
remained regarding causal interaction between immaterial thinking and
material extended substances in his system. Substance dualism also
struggled to coherently account for conjoined mind-body phenomena (Kim,
1998).
Bundle Theory and Empiricism
In reaction to views positing mysterious indivisible substances, empiricist
philosophies proposed alternative conceptions. Hume essentially denied the
existence of substantive minds or objects, reducing them to “bundles” of
momentary perceptions associated through resemblance and causation
(Hume, 1957). For Hume, there are only attribute impressions without
intrinsic essences or substantial beings to bear them.
Berkeley similarly denied existence of independent material substance,
arguing only for finite minds and their ideas as knowable entities. Under
empiricism, attributes constituted the primary contents of experience rather
than manifestations of deeper essences inhering in substances (Berkeley,
1991). However, empiricist accounts struggled to explain cohesion, identity
or external reference if attributes alone comprised reality.
Nominal Essentialism and Natural Kinds
Recent philosophers have advocated revised forms of Aristotelian-style
essentialism integrating natural scientific perspectives. Hilary Putnam’s
internal realism (Putnam, 1982) and Saul Kripke’s arguments around natural
kind terms (Kripke, 1980) suggest essential properties linked to historical
origins rather than intrinsic natures.
On this view, natural kinds like water or gold indirectly denote clusters of co-
instantiated properties emerging from causal histories rather than intrinsic
Platonic essences identifiable a priori. Although essences cannot be directly
intuited, natural kind membership involves essential properties determined
by historical relationships. However, questions remain regarding how
historical dependencies ground strict essences as demanded by essentialism
(Bielskis, 2018).

In reaction to views positing mysterious indivisible substances, empiricist
philosophies proposed alternative conceptions. Hume essentially denied the
existence of substantive minds or objects, reducing them to “bundles” of
momentary perceptions associated through resemblance and causation
(Hume, 1957). For Hume, there are only attribute impressions without
intrinsic essences or substantial beings to bear them.
Berkeley similarly denied existence of independent material substance,
arguing only for finite minds and their ideas as knowable entities. Under
empiricism, attributes constituted the primary contents of experience rather
than manifestations of deeper essences inhering in substances (Berkeley,
1991). However, empiricist accounts struggled to explain cohesion, identity
or external reference if attributes alone comprised reality.
Nominal Essentialism and Natural Kinds
Recent philosophers have advocated revised forms of Aristotelian-style
essentialism integrating natural scientific perspectives. Hilary Putnam’s
internal realism (Putnam, 1982) and Saul Kripke’s arguments around natural
kind terms (Kripke, 1980) suggest essential properties linked to historical
origins rather than intrinsic natures.
On this view, natural kinds like water or gold indirectly denote clusters of co-
instantiated properties emerging from causal histories rather than intrinsic
Platonic essences identifiable a priori. Although essences cannot be directly
intuited, natural kind membership involves essential properties determined
by historical relationships. However, questions remain regarding how
historical dependencies ground strict essences as demanded by essentialism
(Bielskis, 2018).
Process Philosophies and Relational Ontology
Departing from any notion of independently existing substances, process
philosophies like those of Alfred North Whitehead emphasize relationship and
temporal becoming over static essences (Whitehead, 1978). For Whitehead,
fundamental reality comprises occasions of experience (“actual entities”)
that emerge from and influence one another according to creative processes
of concrescence.
Contemporary relational ontology further develops such perspectives,
opposing reified substances/essences in favor of inherently relational
networks comprising events, fields, dispositions and regularities between
dynamic entities (DeLanda, 2006). However, while capturing flux and
emergence, these stances potentially sacrifice identity conditions for things
and universality undermining robust theorizing.
Object-Oriented Ontology
A more moderate approach combining essentialist and relational elements is
found in influential object-oriented ontologies like those of Graham Harman
(Harman, 2018). For Harman, objects possess unique irreducible profiles
distinct from relations yet manifested through them. Objects’ qualities
persist even when relations change, indicating essences beyond correlations
alone.
At the same time, objects always exceed full relations and withdrawal from
full characterization, avoiding intrinsic reification. On this view, objects
comprise dynamic hubs of qualities and capacities with boundaries that
enable but transcend interactions (Morton, 2013). This grants a measure of
independence yet interconnectivity, addressing worries faced by strict
essentialism or flux-only philosophies. However, skeptics argue object
profiles remain fundamentally inaccessible or incoherent.
Concluding Reflections
In closing, surveying metaphysical theories of substance, essence and
properties demonstrates the richness yet complexity of these enduring
problems. Ancient and modern philosophers have proposed diverse
perspectives, from hylomorphic substances and Cartesian dualism to
empiricist bundles, natural kinds and process thought.
Contemporary views offer novel syntheses, with nominal essences emerging
through relations yet objects retaining independence. However, key issues
persist, such as grounding: coherence between independent
essences/objects and relational manifestations; explanation of phenomena
like attributes, change or causal interaction; and epistemological access to
essences.
Overall, philosophizing on these topics reveals metaphysics as an evolving
intergenerational inquiry, with alternative positions continually critiqued and
refined but no consensus attained. Exploring diverse frameworks proves
illuminating even without settlement, as fundamental yet elusive notions
demand ongoing principled yet flexible examination. Questions of substance,
essence and property underlie all ontology and continue stimulating probing
philosophical theorizing.
Questions concerning the nature of substance and essence have been
central to metaphysical inquiry since ancient times. Philosophers have long
pondered such issues as: What is the fundamental entity or substrate that
ultimately composes objects in the world? What features are essential versus
accidental to their identity and character? Differentiating substance from
accidental attributes constitutes a basic problem for ontology.
This essay will examine differing perspectives that have emerged historically
on the notion of substance and essence. It will outline the classical
metaphysical theories proposed by ancient philosophers like Aristotle as well
as more modern ideas. Key distinctions will be drawn between substance and
attribute, essential and accidental properties. The essay will also consider
debates around issues such as universalism versus nominalism regarding
essential natures. Overall, exploring alternative stances on substance and
essence illuminates enduring investigations into fundamental concepts
underlying theories of reality.
Substance Theory in Ancient Philosophy
Some of the earliest comprehensive treatments of substance and essence
were put forth by pre-Socratic and Aristotelian philosophers in ancient
Greece. Pythagoreans and Heraclitus conceived of basic entities changing
through alternating contrarieties as the ultimate substrates of phenomena.
Democritus posited atoms as indivisible, continuously existent substances
capable of diverse combinations (Shields, 2016).
However, Aristotle developed the most influential and systematic classical
theory. In his Metaphysics, Aristotle defines substance (ousia) as the basic
particular entity which underlies all other attributes. Its essence (to ti ên
einai) is that which makes it the kind of thing it is and distinguishes it from
other categories (Aristotle, 1999).
For Aristotle, substances are primary beings that exist in their own right as
individual hylomorphic composites of matter and form. Their essences
constitute the set of properties eternally belonging to the natural kind
without which they could not persist as that kind of entity. By contrast,
attributes like size or location are non-essential or accidental, changeable
properties of substance (Lloyd, 1981).
Aristotle's idea of substance as the ultimate subject of predication capable of
independent existence addressed Parmenidean worries over change by
distinguishing essence from accident. However, questions remained
regarding the ontological status of Platonic Forms and relations between
kinds/attributes/individuals in his system (Code, 1986). His essentialism also
faced challenges explaining accidental features within a deterministic
framework.
Cartesian Substance Dualism
A major development came with René Descartes' 17th century formulation of
substance dualism. For Descartes, ‘substance’ denotes that which requires
nothing else for its existence, possessing either thought (res cogitans) or
extension (res extensa) as its essence. Examining phenomena through
systematic doubt, he saw thinking and physical extension as fundamentally
different kinds of attributes defining the essential natures of distinct mental
and material substances (Descartes, 1989).
Descartes’ conception of self-sufficient thinking substance invoked in his
famous “I think, therefore I am” line marked a radical departure from
Aristotelian hylomorphism. It separated mind and body into fundamentally
heterogeneous ontological categories (Descartes, 1984). However, questions
remained regarding causal interaction between immaterial thinking and
material extended substances in his system. Substance dualism also
struggled to coherently account for conjoined mind-body phenomena (Kim,
1998).
Bundle Theory and Empiricism
In reaction to views positing mysterious indivisible substances, empiricist
philosophies proposed alternative conceptions. Hume essentially denied the
existence of substantive minds or objects, reducing them to “bundles” of
momentary perceptions associated through resemblance and causation
