The Ontology of Origin: Identity as Act, Relation, and Concept
I. Introduction: The Clone and the Son
The metaphysical crisis of our late modern age is not merely a fragmentation of culture or a dissolution of moral norms and political ideals. It is a catastrophic rupture into the non-physical reality of how we are to perceive and interact with and as the world. For our purposes here, this rupture is deep in the very ontology of identity itself. We have dissolved the human subject into a stream of data and the divine nature into a composite idol. Let us consider an example, an allegory (if you will): the ontological distinction between a son and a clone.
In the technocratic imagination of the twenty–first century, governed by the logic of the machine and the archive, identity is increasingly viewed as a distinctive arrangement of information. It is a static list of attributes, a genetic code, a bundle of psychological properties or a résumé of historical events. If one were to replicate perfectly the genetic sequence and synaptic mapping of a man, the modern intuition, shaped by the Idealism of the concept, suggests that identity has been preserved. The clone is, for all intents and purposes, the man. Identity is defined by content.
This is the logic of the Sorites, the heap, where being is reducible to the sum of its parts and the subject is merely the aggregate of its predicates. Against this reductive materialism, which is paradoxically a form of hyper–intellectualism or Idealism, stands the classical and Christian tradition. This tradition asserts that identity is not found in a list of attributes (the clone) but in a causal history (the son). A son is not a son because he possesses a specific set of phenotypic traits, nor because he shares a psychological profile with his progenitor. He is a son because he stands in a specific, irrefutable and unrepeatable relation of origin to a father. Even if a clone were to possess every attribute of the son perfectly, such that he were indiscernible in terms of qualities, he would not be the son. He would be an imposter, a simulacrum, because he lacks the specific act of origin, the historical and ontological trajectory that constitutes the son’s haecceity, his “this–ness.”
The clone is a fabrication of concept, duplicable and definition–dependent. The son is an accomplishment of act, singular and origin–dependent. This distinction marks the definitive red line[1] between pre–modern Realism and modern Idealism. In the former, identity is downstream of act (actus) and origin (archē). In the latter, identity is downstream of concept (ratio) and data (datum). The transition from the former to the latter represents a metaphysical catastrophe: a shift from viewing the world as a hierarchy of participating acts to viewing it as a flat plain of manipulable aggregates. In the classical view, identity is an achievement of being. In the modern view, it is a category of logic.
To understand the gravity of this shift, one must realize that it affects not only how we view ourselves but also how we view the first principle of all reality. If identity is a bundle of parts, then God himself becomes a heap, a composite being dependent on the arrangement of his attributes. This essay argues that true identity is not a primitive logical premise or a data set, but a metaphysical accomplishment of act in the Latin tradition and origin in the Greek. It contends that the shift to Idealism has resulted in a composite God, an idol of the mind, and a dissolved self, leading inevitably to the dual errors of theistic personalism and reductive materialism.
We must therefore begin where the metaphysical tradition itself begins: with the distinction between true unity and mere accumulation. Aristotle, in his investigation of substance, insists that true being cannot be a mere collection of parts. If a thing is simply the sum of its components, it lacks the internal principle of unity that makes it a “this” (hoc aliquid) rather than a “these.” He establishes the foundational premise of hylomorphic ontology against the atomists of his day, who believed reality was merely the accidental collision of particles. A syllable is not merely the letters A and B; it is the letters A and B united by a form that makes them a sound. Similarly, a substance is not its atoms. Aristotle crystallizes the point in a lapidary phrase: “The whole is not like a heap.”[1]
The distinction is precise. A heap (sōros) is defined strictly by the spatial proximity of its parts; its unity is accidental, imposed from without and dissolved the moment the parts disperse. A whole (holon), however, is defined by a principle that transcends the parts, a form or entelechy that binds them into a singular, operating reality. This form is not a physical part; it is the act that makes the parts one. When modern philosophy prioritizes concept (the list of parts or attributes) over act (the unifying principle), it reduces both God and the human self to heaps, bundles of perceptions or properties held together by nothing more than mental association or definitional fiat.
The Aristotelian insight provides a bulwark against the modern dissolution of the subject. If the self is merely a collection of psychological states, as Hume later argues, then the self is a heap and personal identity is a convenient fiction. However, if the self is a substance, an entity in which “primary substances are most properly called substances in virtue of the fact that they are the entities which underlie everything else, and that everything else is either predicated of them or present in them,”[2] then identity is secure, not because the data remains fixed, but because the act of being persists.
Identity, in the classical view, is an ontological accomplishment. In what follows, I will show how this conviction is articulated in the terms of a classical consensus (in the sense of a constructive unfolding over time), and unfolded along the Latin–Greek axes of act and origin, ruptured by modern concept–centered accounts and defended in contemporary debates over divine simplicity and the very possibility of God.
II. The Classical Consensus: The Metaphysics of Being
The Classical Alliance, spanning Aristotelian, Platonic, Islamic, Jewish and Christian traditions, stands united against the notion that identity is a brute fact or a bundle of properties. Identity is an achievement of being. Properties do not float in a vacuum, clustering together to form objects. There is a substrate, a subject, an act that grounds and generates properties. Identity underlies properties; it does not consist of them.
This begins from the Aristotelian conception of ousia (substance). Substance is not merely a coat rack on which accidents hang. It is the ontologically prior reality that allows accidents to exist at all. Accidents exist in substance; substance exists in itself. Aristotle articulates this primacy: “Primary substances are most properly called substances in virtue of the fact that they are the entities which underlie everything else, and that everything else is either predicated of them or present in them.”[Ibid] Without this underlying reality, the world collapses into a flux of transient qualities with no anchor – a prescient anticipation of the bundle theories that emerge two millennia later.
The classical tradition does not stop at the assertion of substance; it interrogates the vertical causality that sustains substance. Finite substances are contingent. They participate in perfections they do not exhaust. A beautiful object is not Beauty itself; it has beauty by participation. This vertical anchor of identity is Platonic in origin, and it is taken up and baptized by Christian thought. Plato argues that particular identities are sustained by their relation to the Forms, specifically the Beautiful and the Good: “If there is anything beautiful besides the Beautiful itself… it is beautiful for no other reason than that it shares in that Beautiful… all beautiful things are beautiful by the Beautiful.”[4] Identity is not closed in upon itself; it is ecstatic, ordered to a higher source.
Bonaventure extends this in a comprehensive semiotic ontology, where the entire created order is a system of signs pointing back to the Creator. The identity of a creature is not self–contained but referential. To look at a creature and see only its physical attributes is to miss its true identity as vestige, image and likeness of God. “All creatures are shadows, echoes, pictures… of that Eternal Source and Art.”[5] The creature is a “shadow” insofar as it possesses being, an “echo” insofar as it reflects divine harmony and a “picture” insofar as it manifests intelligible form. Its identity is derivative, flowing entirely from the eternal source. To define a thing solely by its internal data (its concept) is to misunderstand what it is. Its “is–ness” is a received act from the Creator.
The Six Principles of Simplicity (The Adequacy Criterion)
To ground this ontology of identity, the classical tradition develops a rigorous apophatic discipline regarding the first principle, God. If God is the source of all identity, he cannot possess identity in the same composed way creatures do. He cannot be a heap of attributes. He must be absolutely simple. The doctrine of divine simplicity (DDS) is not a peripheral thesis; it is the adequacy criterion for any coherent theism. It rests on six interlocking principles that guard the divine nature from reduction to a composite object.
1. Pure Actuality
The first principle must be free of all potentiality. Potentiality implies a capacity to change, acquire something new or cease to be. It marks a gap between what a thing is and what it could be. If the first principle had potentiality, it would require a prior cause to actualize that potentiality, which would terminate in an infinite regress. Therefore the source of motion and being must be fully actual. Aristotle deduces the necessity of this pure act: “Since there is something which moves while itself unmoved, existing actually, this can in no way be otherwise.”[6] God is not becoming; God is. His identity is not a trajectory toward perfection; it is the fullness of perfection in act. This distinguishes divine identity from all creaturely identity, which is always a mixture of act and potency, of what it is and what it can still be.
2. Cause of Unity
In any composite being, the parts are conceptually and ontologically prior to the whole. Matter and form, essence and existence, substance and accidents are distinct principles that must be brought together. Distinct things do not unite themselves; they require an agent to bind them. If God were composed of parts – for example “God” plus “goodness” plus “power” – he would require a composer. Aquinas formulates the point with precision: “Every composite is posterior to its component parts, and is dependent on them. … every composite has a cause, for things in themselves different cannot unite unless something causes them to unite.”[7] A composite God is a caused God, and a caused God is no God at all. Identity in God is not an assembly of perfections; it is the simple identity of the self–subsistent act of being.
3. Non–posteriority
From the rejection of composition follows the principle of priority. God is first (primum). There is no reality before him or behind him. In any composite entity the parts are ontologically prior to the whole; the atoms are prior to the molecule, the essence is prior to the existent instance. If God were composite, the parts of God would be prior to God. This is metaphysically impossible for the primal cause. Bonaventure therefore describes God as the absolute convergence of all perfection, not as a collection but as a simplicity that contains all multiplicity eminently: God is “an undivided light of pure act, in whom all distinct forms subsist in absolute simplicity.”[8] God does not have unity as one perfection among others; he is the unity that grounds all other unities, the archetype of identity, not a participant within a larger order.
4. Not in a Genus
Creaturely identity is often articulated by genus and specific difference (for example “animal” plus “rational” equals “man”). This structure implies composition: a general substrate determined by a specific qualifier. God, however, cannot be classified. He is not a type of being. He is being itself (ipsum esse subsistens). He has no limiting difference because he has no potentiality to limit. To place God in a genus is to subject him to a common measure, to make him one member of a larger class. Aquinas shows that genus implies potentiality; in the mind, genus is prior to what it contains. “But nothing is prior to God either really or mentally. Therefore God is not in any genus.”[9] God is not a being among beings; he is the act by which there are beings at all.
5. Pure Existence / No Quiddity
Perhaps the most radical insight of the classical alliance[2] comes from Avicenna’s distinction between a thing’s “whatness” (quiddity or essence) and its “thatness” (existence). In everything other than God, essence and existence are distinct; one can conceive a phoenix without knowing whether it exists. This distinction is the root of contingency. In God there is no such distinction. His essence is to exist. He is not a “what” that happens to be. If he were, he would be contingent on the addition of existence to essence. Avicenna writes: “The First has no quiddity other than His individual existence… He is pure existence [mujarrad al–wujūd] with the condition of negating privation and all other description of Him… everything other than Him has addition.”[10] Pure existence here is not a thin abstraction but the infinite intensity of act, unconstrained by any delimiting form. The classical God does not have existence; he is the act of to–be.
6. Unity of Attributes
Modern thinkers often confuse the multiplicity of names we use for God with a multiplicity in God. Because we speak of mercy and justice as distinct concepts, they assume there are distinct properties in God corresponding to them. Maimonides warns that this leads to a subtle polytheism, where “God” becomes a substrate holding together several distinct realities. For the classical theist, God’s mercy is his justice, which is his power, which is his essence. The distinctions exist only in our finite mode of knowing, not in his infinite mode of being. Maimonides insists: “There cannot be any belief in the unity of God except by admitting that He is one simple substance, without any composition or plurality of elements… Those who believe that God is One, and that He has many attributes, declare the unity with their lips, and assume plurality in their thoughts.”[11] The attributes are not ingredients of the divine nature; they are names for the one simple and infinite act of being that God is.
“Strong Simplicity”
In contemporary debates there has been some concerns that in re-inserting the explanatory power of divine simplicity into the contemporary project, some scholars have gone overboard and have argued for a type of simplicity that goes beyond what can be defended between the tensions of faith and reason, and strains faith commitments. This is too complicated a debate to delve into here. The point of these 6 principles is to show that simplicity as an accomplishment, or profile, is uncontroversial when framed like this. Even, where some of these ideas are later than some orthodox developments, they’re nascent in foundational works. Below is a table of the Cappadocian Fathers commitments as the quintessential example of this continuity. As one can see in this table, assuming its right, they may use a different idiom, or emphases at times, but the above principles are not contradictory to their commitments, and if anything undergird and strengthen them, when properly appropriated and thought out well for the classical task, like we’re doing here with the concept of identity.
The Cappadocian Scorecard on Divine Simplicity:
| Principle | Cappadocian Commitment | The Historical Nuance (The “Interplay”) |
| 1. Pure Actuality (No Potentiality) | High. | They affirmed God is immutable and unchanging. However, they preferred the language of “Infinite Life” or “Power” (Dynamis/Energeia) over Aristotelian “Act.” For Nyssa, God is “perfect” not because He is static (like a rock), but because He possesses Infinite Power that never fails or changes. |
| 2. Cause of Unity (No Parts) | Absolute. | This was their main weapon. They argued the Father, Son, and Spirit are not parts of God. If they were parts, there would be a “Whole” greater than the Father. They insisted that the entirety of the Godhead is in the Father, the entirety in the Son, etc. (The doctrine of Perichoresis or mutual indwelling). |
| 3. Non-Posteriority (Uncausedness) | Complex. | The Tension: The Father is Uncaused. The Son is Caused (Begotten). The Solution: They distinguished between Ontological Cause (creating a thing) and Hypostatic Origin (transmitting the same nature). The Son is “caused” only in origin, not in time or nature. Therefore, the Divine Nature remains “Uncaused” even if the Person of the Son is “from the Father.” |
| 4. Not in a Genus (No Common Measure) | The Danger Zone. | The Problem: Basil’s famous Letter 38 uses the analogy: Ousia is to Hypostasis as “Human” is to “Peter/Paul.” This violates Principle 4 (it makes God a genus). The Fix: Gregory of Nyssa (in To Ablabium) explicitly corrects this. He admits the analogy is imperfect. He argues God is not a species with three members. He says we only count “three men” because men act separately. The Trinity acts with One Operation. Therefore, they are not a genus of three; they are a Singular Reality. |
| 5. Pure Existence / No Quiddity | Modified (Apophatic). | They would agree God has no “definition” (Quiddity) that limits Him. But rather than saying God is “Pure Existence” (Latin: Esse), they focused on Apophaticism (Negative Theology). We cannot know what God is; we only know that He is. They fiercely rejected Eunomius’s claim that we can know God’s Essence. |
| 6. Unity of Attributes | Absolute. | They argued that “Good,” “Wise,” and “Just” are not distinct parts of God. They are concepts our minds create (Epinoia) to describe the One Simple Reality. This is identical to Maimonides/Aquinas. |

III. The Divergent Paths of Realism: Latin Act vs. Greek Origin
Like Simplicity we have some divergence East and West but there is not contradiction, and politics of ecclesial bodies aside, there’s probably not much tension about the idea as well. Within the classical alliance, as it relates to identity proper, there is nuanced divergence regarding how identity is principally articulated. Again, not a contradiction but a difference in emphasis, a stereoscopic vision of the same reality. The Latin West tends to ground identity in the metaphysics of act (esse), focusing on the substantial form that actualizes matter. The Greek East anchors identity in the metaphysics of origin (monarchia), focusing on the relational vector by which being is received. Both reject the modern notion of identity as a bundle of concepts or a statistical correlation of data.
The Latin Route: Identity via Act
For Thomas Aquinas and the Latin scholastics, identity is fundamentally an issue of the communication of esse (existence). A thing is what it is because of its act of being. In the hylomorphic structure of the human person, the soul is the substantial form that confers identity by communicating existence to the body. The body does not have a separate existence that the soul inhabits like a pilot in a ship. The whole person subsists in the single existence of the soul. Aquinas writes: “The soul communicates that existence in which it subsists to the corporeal matter; and thus from the soul and the matter there results unity of existence, so that the existence of the whole composite is also the existence of the soul.”[12]
Here, identity is vertical and energetic. The self is not a Cartesian ghost in a machine nor a Humean bundle of sensations. It is a hylomorphic unity sustained by a continuous act of existence that derives from God. Identity is the act of persisting in being. This is why the Latin tradition emphasizes the beatific vision as the perfection of identity. The intellect’s union with the act of all acts stabilizes and glorifies creaturely being. The soul does not lose its identity in God; it finds that identity fully realized in the source of its act.
The Greek Route: Identity via Origin
The Cappadocian Fathers and the Byzantine tradition approach identity through relation and origin. While the Latin West contemplates the vertical stability of actus essendi, the Greek East contemplates the dynamic flow of the monarchia. This appears most clearly in their Trinitarian theology, which functions as the archetype of their ontology.
For the Greek Fathers, the red line of reality is not only the Aristotelian distinction between act and potency but the abyss between uncreated and created. Gregory of Nyssa establishes this fundamental binary as the primary coordinate of all identity: “The ultimate division of all that exists is made by the line between ‘created’ and ‘uncreated’, the one being regarded as the cause of what comes to be, the other as what comes to be.”[13] Identity is determined by one’s position relative to this line. The uncreated is the cause; the created is the effect.
The divine persons are distinguished solely by relations of origin: the unbegotten Father, the begotten Son and the proceeding Spirit. The Father’s identity is not found in a list of absolute attributes, such as omnipotence or wisdom, which he shares fully and identically with the Son and Spirit. Rather, his identity is his status as source. Identity is relational and directional. Gregory of Nazianzus articulates this “monarchy” of the Father as the guarantor of divine unity: “It is… a Monarchy that is not limited to one Person… but one which is made of an equality of Nature and a Union of mind, and an identity of motion, and a convergence of its elements to unity… so that though numerically distinct there is no severance of Essence.”[14]
This focus on origin leads to a radical apophaticism regarding essence. If identity is relational, the “whatness” of God remains beyond conceptual grasp. We know that he is uncaused, but not what he is. Gregory presses the point through Christology: “He Who is now Man was once the Uncompounded… In the beginning He was, uncaused; for what is the Cause of God? But afterwards for a cause He was born.”[15] The Father has no cause; therefore he has no definition in creaturely terms. He is pure origin, marked only by the negation of origin (unbegottenness).
Simplicity for the Greeks is therefore the refusal to decompose God into parts or definitional components. Gregory of Nyssa insists: “The Divine nature, whatever it is in its essence, is simple, uniform, and incomposite, and cannot be viewed under any form of complex formation.”[16] Yet this simplicity is not a static mathematical point. It is dynamic and fecund. The distinction between essence and energies allows for real participation in God without pantheistic confusion. Gregory Palamas argues that we can know God and participate in his life without shattering his unity: “He is divided without being divided… For God is One in essence and energy.”[17] The divine essence remains imparticipable; the divine energies are truly communicable. This distinction allows for creaturely identity as participation in divine life without collapsing God into the world or the world into God.
The Mechanism of Unity
The crucial insight of the Greek tradition is that the unity of God is not a bare numerical oneness but the perichoretic unity of one operation. We do not count three gods because there are not three separate powers or wills in competition. There is one divine operation. When the Father wills, the Son acts and the Spirit perfects in a single motion of the Godhead. Gregory of Nyssa uses this unity of operation to defend monotheism against the charge of tritheism: “The divine operation is always observed to be one… the name [God] derived from operation cannot be divided among many where the result of their mutual operation is one… so neither are they called three Gods.”[18]
Gregory of Nazianzus describes this unity as perichoresis, mutual indwelling, where each person is fully transparent to the others: “Each of these Persons possesses Unity, not less with that which is United to it than with itself… and this is the cause of the Unity of the Trinity.”[19] Identity here is not a barrier but a mode of communion. The Father is who he is by giving; the Son by receiving and returning; the Spirit by proceeding as shared fruition. Identity is the capacity for total self–donation without loss.
Technical Logic: Type Safety in Theology
“Type safety” is not a technical term from philosophical logic, and it is not being presented here as a proof that the Trinity “works” because a formal system says so. It is an analogy borrowed from typed reasoning in logic and in programming: a discipline of speech that prevents category mistakes by refusing to combine expressions that belong to different kinds. In ordinary terms, it is the rule “do not mix levels.” One does not ask whether the number seven is jealous, or whether justice weighs three pounds, because the very grammar of those sentences is wrong. The point of invoking “type safety” is simply this: many Trinity objections arise because they treat theological statements as if they were built out of the wrong grammatical categories, and once that slide is blocked, the alleged contradiction never gets off the ground.
Many modern critiques assume that “God” functions like a count noun in the same way “man” or “star” does. On that assumption, “the Father is God, the Son is God, the Spirit is God” is heard as if it meant “here are three items, each of which is one member of the kind God,” and the conclusion “there are three Gods” seems forced by ordinary counting. But that is precisely where the category mistake occurs. The doctrine is not using “God” as a kind-term that can be multiplied across several members, and it is not using “is” in a way that invites that kind of counting. The contradiction is produced by smuggling in creaturely rules for sorting and counting and then applying them to what is not a creaturely kind.
Classical Trinitarian grammar blocks that mistake by distinguishing person and essence and, with that distinction, distinguishing two different uses of “is.” In one use, “is” expresses identity between items of the same kind: this is that. In another use, “is” expresses predication: this is wise, this is human, this is divine. When classical theology says “the Father is God,” it is not asserting that the Father is numerically identical to the divine essence as though a person and a nature were items of the same type, and it is not asserting that “God” names a genus with three individual instances. It is asserting that the Father is fully divine, that the one undivided divine nature is wholly present and expressed personally in the Father. The same predication is true of the Son and the Spirit. The word “God,” in this usage, functions to name the one divine nature, not a class of beings.
Once that appropriation is made explicit, the counting problem looks different. The tradition is not distributing the divine nature into three shares, as if each Person had one third of deity. It is saying the opposite: the whole divine reality is indivisible and is not parceled out. Therefore, affirming full divinity of Father, Son, and Spirit does not introduce three essences, and it does not introduce three gods by multiplication of a kind. What introduces “three” is not essence but personal distinction: the Persons are irreducibly distinct by relations of origin, not by separate parcels of divinity, separate centers of being, or separate sets of attributes.
This is why patristic language about divine being has the shape it does. Created beings possess being by participation and limitation, and therefore they belong to kinds that can be multiplied and counted across many individuals. God, however, is not one participant within a genus, but the fullness of being itself, lacking any before or after, limitation or partition. Speaking of “one God” is therefore not primarily an arithmetic report about an item alongside other items. It is a confession of indivisible simplicity: God is not composed, not one being among beings, and not a kind with multiple members.
The result is “type safe” only in this modest and clarified sense. The grammar refuses an invalid inference. It does not allow a claim of divinity to be treated as a same-kind identity statement, and it does not allow “God” to be treated as a creaturely count noun. With that discipline in place, the Father, Son, and Spirit can be confessed as one God because they are one undivided essence and one divine operation, while also confessed as three because they are three irreducible relations of origin. The unity is not a collection; the plurality is not a division. Identity remains grounded in act and origin, not in a heap of attributes or a merely conceptual definition.
For more, I’ve worked a bit on this issue from another angle here: Leibniz’s Law and Identity? – RobertDryer
The Pivot: Descartes and the Aggregate
The rupture begins with René Descartes. Seeking mathematical certainty, Descartes finds the hylomorphic unity of the scholastics – where form and matter are correlative principles – unsatisfactory. To secure a foundation of knowledge that is clear and distinct, he posits a stark dualism of res cogitans (thinking thing) and res extensa (extended thing). In doing so he explicitly abandons the Aristotelian notion of substantial form, the very principle of internal unity. For Aristotle, form is the soul of the object, the intrinsic source of its identity and operation. For Descartes, matter is inert extension, defined solely by geometry and motion.
Descartes concedes the shift candidly: “I do not entirely reject substantial forms, but I hold that they are unnecessary in setting out my explanations.”[21] By declaring substantial forms unnecessary, he decapitates the ontological principle of unity and reduces the physical world to geometry and mechanics. The cosmos ceases to be an organism and becomes a machine.
Without substantial form, what makes a material object “one” thing? Nothing internal. What remains is pure extension, matter arranged in space. Without a form to unify it, a material object is only a collection of parts held together by external forces. Identity becomes accidental and conventional. Descartes allows as much in correspondence, defining a material object as “only an aggregate of qualities and properties.”[22] The heap that Aristotle rejected becomes the standard definition of reality. This gives birth to the mechanical universe, a world without intrinsic natures, without teleology and without haecceity.
Leibniz and the Complete Concept
Gottfried Wilhelm Leibniz attempts to rescue substance from Cartesian mechanism. He sees that if everything is just extended matter, there is no genuine unity and hence no real being. But he does not return to act of existence. Instead, he retreats into the realm of concept. Substance is redefined not by its act of being but by its logical description. An individual substance (a monad) is identified by its “complete concept.”
In the classical view, Caesar is Caesar because he exists, because there is a substantial act that persists through change. For Leibniz, Caesar is Caesar because he matches the definition of Caesar. To be Caesar is to possess a concept that contains every predicate true of Caesar, past, present and future. “The nature of an individual substance or of a complete being is to have a notion so complete that it is sufficient to include and to allow the deduction of all the predicates of the subject to which this notion is attributed.”[23]
Identity becomes an informational problem. Leibniz makes this explicit in his correspondence with Arnauld: “The concept of the individual Caesar includes everything that ever happened to him, such as that he was dictator, that he conquered Pompey, that he was assassinated in the Senate on the Ides of March, and all the other details of his life.”[24] Identity collapses into biography. The subject is a data file.
This drives him to the principle of the identity of indiscernibles. If identity is based on concepts, then two things with exactly the same attributes must be identical. There is no this–ness outside what–ness. “In nature there are never two beings which are perfectly alike and in which it is not possible to find an internal difference.”[25] If they matched in data, they would be the same being. Every substance becomes a mirror of the universe: “Every substance is like an entire world and like a mirror of God, or indeed of the whole world which it portrays.”[26] The self is now a point of perspective defined by its information profile. Identity is fully downstream of concept.
Hume and the Dissolution into a Bundle
If Descartes reduces the body to a heap of extension and Leibniz reduces the self to a complete concept, David Hume takes the final step and dissolves substance altogether. Empiricism, stripped of metaphysical commitments, accepts as real only what can be perceived. Looking within, Hume searches for the Cartesian ego or the Leibnizian monad. He finds neither. There is no underlying act, no substantial form, no enduring self.
What he finds is a stream of data: impressions, sensations, thoughts and memories. Without the classical metaphysics of act to ground the self, he concludes that the self is an illusion, a grammatical fiction used to tie together otherwise disconnected events. There is no “I” that has perceptions. There are only perceptions. “I never can catch myself at any time without a perception, and never can observe any thing but the perception… [Mankind] are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in a perpetual flux and movement.”[27]
Bundle theory is the inevitable end of the modern turn. Once identity is severed from act and origin, it becomes a heap of psychological data. The whole is gone; only the heap remains. Identity is no longer an ontological accomplishment sustained by the Creator. It is a statistical correlation of mental states, a narrative thread over a void. The clone replaces the son; the bundle replaces the soul.
V. The Theological Stakes: Simplicity or Atheism
The consequences of this metaphysical rupture are not confined to anthropology. They are catastrophic for theology. The shift from simplicity (God as pure act) to complexity (God as a bundle of attributes) yields a composite God, who in the final analysis is a creature. This is the god of theistic personalism, numerically one but metaphysically composed.
If identity is defined by bundle theory – if a thing is the sum of its properties – then God becomes a bundle. He becomes a substrate (divine essence) to which great–making properties (omniscience, omnipotence, benevolence) are attached. Superficially, this preserves monotheism: there is only one such maximal being. But it destroys transcendence. A God composed of parts requires an explanation for the unity of those parts. A God who “has” properties is distinct from those properties and therefore dependent on them.
The Logic of Atheism in Theistic Personalism
In contemporary philosophy of religion, this battle is fought between classical theism, which upholds simplicity as the guarantee of God’s absoluteness, and analytic theistic personalism. Theistic personalism treats God as a “person” in a modern, post–Lockean sense: a center of consciousness with distinct properties that he possesses. God is a maximal person, differing from human persons in degree, not in kind. He knows more, can do more and is more morally excellent, but his ontological structure is that of a creature: a substance plus properties.
Gregory Fowler, for example, tries to preserve monotheism without simplicity by appealing to “priority monism.” God has distinct parts or aspects, but the whole is ontologically prior to them. On this view, God grounds his own parts; they do not ground him.[28] Identity is still composite, but the composite is said to be basic.
From a classical point of view, this is incoherent. Even if the whole is explanatorily prior, it still depends on its parts to be what it is. A wall may determine the function of bricks, but without bricks there is no wall. If God has parts, even if he “grounds” them, he still depends on them. He is no longer a se, from himself, but ex partibus, from parts. This contradicts the very notion of first cause. Aquinas’s observation remains decisive: “Every composite is posterior to its component parts… things in themselves different cannot unite unless something causes them to unite.”[29] A God who grounds his own parts pulls himself up by his ontological bootstraps. Fowler’s God is a heap that somehow holds itself together.
Timothy O’Connor, in a different way, objects to simplicity on the basis of “modal collapse.” If God is simple, his will is identical with his essence. Since his essence is necessary, his will is necessary. Therefore, God must create this world; he could not have done otherwise. Divine freedom collapses into necessity.[30] To avoid this, O’Connor posits real distinctions between God’s nature and will, fragmenting the simple act into parts.
The classical response distinguishes between the necessity of God’s being and the contingency of his effects. God’s single, simple act of will is necessary, but the term of that act (this or any created order) is not. God does not deliberate between options; he is not one agent among others. The “modal collapse” argument imposes creaturely models of choosing on the creator and then uses the resulting distortions to deny simplicity. In doing so, it introduces potentiality into God. A God with unrealized alternatives is a God with potency and therefore a being among beings, not the first act beyond being and non–being.
The Fregean Error and Hart’s Verdict
David Bentley Hart identifies the root of these modern theological errors in a misapplication of modern logic to metaphysics. Following Frege and Russell, many analytic philosophers treat “existence” as a mere quantifier – a logical function such as “there exists an x such that…” – rather than an act. They then treat God as a being that satisfies a certain maximal description within that logical field. God becomes the greatest instance in a class, not the ground of the class.
Hart argues that this shift undercuts the very idea of God as first principle. “Almost invariably… the departure from traditional metaphysical claims is prompted by a vaguely Fregean style of thinking… it seems obvious to me that a denial of divine simplicity is tantamount to atheism.”[31] The judgment is not rhetorical excess. If God is not simple, he is composite. If he is composite, he is caused. If he is caused, he is not God. To worship a maximal composite is to worship a creature.
Gregory of Nazianzus had already articulated the logic in premodern terms: “Every compound is a starting point of strife, and strife of separation, and separation of dissolution.”[32] Composition is the seed of death. To ascribe composition to God is to ascribe to him the seeds of his own dissolution. A composite God is a God whose unity is fragile and whose being is contingent.
Simplicity as Peace
The rejection of composition is not mere logical hygiene. It is the preservation of divine sovereignty and the only metaphysical guarantee of peace. In the classical tradition, peace is not simply the absence of conflict. It is the tranquility of order and the fullness of being. A composite being, by definition, lacks this fullness. It is a tension of disparate elements – essence and existence, substance and accident, potency and act – held together by a unifying cause. This tension marks a deficiency. Only pure act is entirely at rest in itself.
If God were composed of distinct attributes – justice, mercy, power, will, intellect – conceived as separable aspects, there would be the possibility of internal fracture. Popular theology often imagines God as torn between the “demands” of justice and the “desires” of mercy, as if God were a conflicted finite subject. This is the mythological God, a projection of the divided human psyche onto the infinite. Against this, Nazianzus warns that composition is the root of strife and dissolution.
For the Christian, assurance of salvation rests on the simplicity of God. If God were complex, he would be mutable. If mutable, his promises would be contingent. A God who has love as a property could, in principle, cease to be loving. But the apostolic witness is that “God is love” (1 Jn 4:8). Aquinas grounds this confidence in the identity of divine essence and existence: “God is not only His own essence… but also His own existence.”[33] God’s love is not a mood or posture toward the world; it is identical with his being. He cannot cease to love without ceasing to be, and he cannot cease to be.
Abandoning simplicity for the personalist God of recent analytic models trades the rock of ages for a very large but finite stone. Such a being might be a powerful ally, but he cannot be the ground of being. True peace, the peace that surpasses understanding, is found only in the God whose identity is not an assembly of ingredients, but the eternal act of origin from which all being and all peace flow.
VI. Conclusion: The Ontology of Origin
From the thought experiment of the clone and the son through the hylomorphic dissolution of the bundle, a single conclusion emerges: identity is an accomplishment. It is not a static datum in a registry of attributes or a mere logical relation between a name and a predicate. It is a dynamic act of being and origin.
The metaphysical boundary I have traced separates two incompatible ontologies. On one side lies the world of the heap, where reality is an aggregate of manipulable parts and identity is a label for a cluster of data. On the other side lies the world of the whole, where reality is a hierarchy of participating acts and identity is the persistent energy of a nature received from a source.
The classical tradition, synthesizing the metaphysical rigor of Athens with the revealed history of Jerusalem, presents a universe where identity is thick. It is substantial, weighted with the gravity of existence. This thickness is secured by the stereoscopic vision of the Latin and Greek traditions. For the Latin West, identity is grounded in actus essendi, the act of existence. A thing is, only because it participates in uncreated act. It hovers over the abyss of nothingness not because it has a stable definition but because it is being sustained by the simple will of the Creator. For the Greek East, identity is grounded in relations of origin. A person is, because he stands within a history of begetting, proceeding and sending. The Son is Son not because he has a property called “sonship,” but because he is eternally begotten of the Father. The creature is creature because it is spoken by the Word and vivified by the Spirit.
The modern project attempts to ground identity in the concept, in the exhaustive list of predicates imagined by Leibniz and the bundle of perceptions described by Hume. This shift from realism to idealism, from act to data, evacuates the subject. By redefining substance as a complete concept, Leibniz imprisons the self in its description. By searching for the self in the stream of perceptions without the lens of substance, Hume dissolves the self into a bundle and reduces “I” to a grammatical convenience. The anthropological result is the reduction of the human being to a clonable archive of biological and psychological information.
The theological result is more radical still. It transforms the divine into a composite, a list of maximal attributes held together by conceptual unity rather than by simple act. The God of theistic personalism is a being made up of parts, a heap of perfections that requires a cause to explain its unity. As Aristotle and Aquinas already saw, a composite god is a caused god, and a caused god cannot be the first principle. To worship such a being is to worship a maximal creature. It is in this precise sense that the denial of simplicity is, as Hart concludes, “tantamount to atheism.”[34] It replaces the source of being with one more being, however exalted.
To recover both self and God, theology must cross back over the red line. We must abandon the aggregate logic of the heap and return to the participatory logic of the whole. We must recognize that true identity is not primarily a matter of what we contain (our properties) but whence we come (our origin) and by what power we stand (our act). We must recover Bonaventure’s insight that every creature is a “shadow” and “echo” of the eternal art, possessing no identity apart from its relation to the source. We must recover Gregory of Nazianzus’s insight that the unity of God is not a numerical puzzle but the monarchic peace of the Father, from whom, through whom and in whom all things are.
The clone may have the same DNA as the son. He may satisfy every criterion of Leibniz’s identity of indiscernibles. He may match the complete concept. But he is not the son. He is a simulacrum. He has the concept but lacks the origin. He has the data but lacks the act.
Identity is not a résumé; it is a relation. Ultimately it is origin – the undivided light of pure act – that constitutes the true name of the real. Modernity offers us the freedom to curate ourselves as bundles of attributes, to construct identities from chosen data. The classical tradition offers a different freedom: to receive ourselves as gift, to find who we are not in the mirror of our own consciousness, but in the gaze of the origin who speaks us into being.
