The dyad of form and matter constitutes one of the most persistent structural axes in the depth-psychology corpus, reaching from Aristotle's hylomorphic framework through Neoplatonist elaboration, early modern natural philosophy, and into the twentieth-century critiques of Gilbert Simondon. The corpus does not treat the pair as a resolved doctrine but as a site of productive tension. Plotinus interrogates the ontological status of matter as pure privation and asks whether form can coherently be said to reside in matter as in a substrate; his answer—that form is rather the completion matter's potentiality demands—already unsettles the clean symmetry of the schema. Simondon mounts the most sustained critique in the library: the hylomorphic schema, he argues, encodes a socially determined, master-slave division of labor and fails entirely to account for implicit physical forms and the energetic mediation that actually constitutes individuation. Aristotle's De Anima contributes the teleological dimension: ousia in the fullest sense tends toward form or essence, binding the dyad to questions of substance and soul. Aurobindo reconfigures the pair along a spiritual-evolutionary axis in which matter is not opposed to spirit but is a form of spirit. Across these voices the central tension is whether form actively informs passive matter, or whether individuation arises from a pre-individual energetic field that neither pole can fully capture.
beings can be known through the knowledge of the subject, but the individuation of beings can only be grasped through the individuation of the subject's knowledge. PART I Physical Individuation CHAPTER ONE Form and Matter
Simondon announces his foundational chapter on form and matter, arguing that physical individuation—and not static hylomorphic categories—is the proper object of inquiry.

it would not be precise to say that the form plays a static role while the matter plays a dynamic role; in fact, in order for there to be a single system of forces, the matter and form both must play a dynamic role
Simondon refutes the classical assignment of stasis to form and dynamism to matter, proposing instead that both poles are energetically active within a single system of forces.
, Individuation in Light of Notions of Form and Information, 2020thesis
the hylomorphic schema primarily reflects is a socialized representation of labor and an equally socialized representation of the individual living being; the technical operation that imposes a form on a passive and undetermined matter isn't just an operation considered abstractly
Simondon argues that the hylomorphic schema is not a neutral ontology but a social artifact encoding the free man's command over passive matter executed by the slave.
, Individuation in Light of Notions of Form and Information, 2020thesis
the form, which is here represented by the mold, plays an informing role by exerting forces without work, forces that limit the actualization of the potential energy momentarily borne by the matter. This energy can be actualized in a given direction with a given rapidity: the form is the limit.
Simondon redefines form as a limiting condition on the actualization of potential energy carried by matter, replacing the classical image of form as an imposed shape.
, Individuation in Light of Notions of Form and Information, 2020thesis
The basic-constituents of things must be either their Form-Idea or that Primal Matter [of the Intelligible] or a compound of the Form and Matter. Form-Idea, pure and simple, they cannot be: for without Matter how could things stand in their mass and magnitude?
Plotinus establishes that sensible things must be compounds of Form-Idea and Matter, since Form alone cannot account for physical extension and magnitude.
, The Six Enneads, 270thesis
The hylomorphic schema is insufficient to the extent that it does not account for implicit forms, since it distinguishes only the explicit, imposed form from the undifferentiated, passive matter.
Simondon identifies the structural inadequacy of the hylomorphic schema: its binary of explicit form and passive matter cannot register the implicit physical forms that science and technology actually engage.

Becoming may be divided into Matter and the Form imposed upon Matter. These may be regarded each as a separate genus, or else both may be brought under a single category and receive alike the name of Substance. But what, we may ask, have Matter and Form in common?
Plotinus presses the question of whether matter and form share enough ontological ground to belong to a single genus, problematizing their conventional pairing under the category of substance.
, The Six Enneads, 270thesis
It may be claimed as a common element in Matter, Form and the Couplement that they are all substrates. But the mode in which Matter is the substrate of Form is different from that in which Form and the Couplement are substrates of their modifications.
Plotinus distinguishes between the senses in which matter and form each function as substrates, arguing that form is not simply a resident of matter but the completion of its potentiality.

what makes one object different from another is the set of particular limits—varying from one case to another—that guarantee that this object possesses its haecceity; the experience of the recommencement of the construction of objects coming out of the technical operation is what gives the impression of attributing to matter the differences
Simondon traces the attribution of the principle of individuation to matter back to the technical experience of repeated production, exposing it as a pragmatic impression rather than a metaphysical fact.

the preparation of the clay seeks to obtain homogeneity and the best degree of chosen humidity to reconcile plasticity and consistency… the molecular reality of the clay and of the water it absorbs is organized by the preparation in such a way as to be able to behave during individuation as a homogeneous totality
Through the concrete example of clay preparation, Simondon shows that matter is never purely passive but must be brought to a state of energetic readiness before form-taking can occur.

it is clear enough that the most successful candidates will be essence and the closely related notion of form. That Aristotle should come, however tentatively, to the conclusion that ousia in the fullest sense is form or essence
Aristotle's De Anima concludes that ousia in its highest sense is form or essence, grounding the hylomorphic framework in a teleological account of substance.

Matter can take no increase by anything entering it, and no decrease by any withdrawal: what from the beginning it was, it remains. It is not like those things whose lack is merely that of arrangement and order which can be supplied without change of substance
Plotinus argues that matter is absolutely immutable in its own nature, receiving and releasing ideal-forms without itself undergoing change, making it radically distinct from the composite things it underlies.

does not this precisely mean that it never ceases to be itself, in other words that its one form is an invincible formlessness? In no other sense has Plato's dictum any value
Plotinus interprets matter's perpetual evasion of determinate form as its own paradoxical 'form'—an invincible formlessness—reconciling Platonic doctrine with his own metaphysics.

the potential of the control grid is utilized as a variable mold; the distribution of the support of energy in proportion to this mold is so rapid that it is carried out without an appreciable delay… a modulator is a continuous temporal mold.
Using the electronic modulator as a limit-case, Simondon extends the form-matter relation into continuous temporal process, where form becomes a variable mold and matter approaches pure potential energy.

the living being is to itself partially its own principle of individuation; it continues its individuation, and, instead of merely being a result that progressively degrades, the result of an initial operation of individuation becomes the principle of a further individuation.
Simondon distinguishes the living being from the technical artifact by showing that in the living being form-matter individuation is not a completed event but an ongoing self-constituting process.

the Matter of the realm of process ceaselessly changes its form: in the eternal, Matter is immutably one and the same, so that the two are diametrically opposites.
Plotinus draws a sharp ontological contrast between sensible matter, which takes on successive forms, and intelligible matter, which is immutably one—distinguishing two entirely different registers of the form-matter relation.

why should Being in its totality end up integrally in a multiplicity of individualities to be known? Why would the being, as such, not include a pre-individual dimension?
Simondon questions the Aristotelian primacy of the individual, proposing that being harbors a pre-individual dimension that the hylomorphic form-matter schema systematically suppresses.

what makes it such that the object is itself is the fact that the state of its matter at any moment summarizes all the events that this object has undergone; form, which is merely a fabricating intention, a voluntary arrangement, can neither
Simondon argues that the haecceity of an object resides in its material history rather than in its imposed form, inverting the classical priority of form as the principle of identity.

Matter entire takes Magnitude and every particle of it becomes a mass; in this way, by virtue at once of the totality of Idea with its inherent magnitude and of each several specific Idea, all things appear under mass
Plotinus explains how matter acquires extension and mass through the irradiation of Ideal-Forms, illustrating the cosmological mechanics by which form actively constitutes the material world.

Matter is of all that most in need; its next is the lowest Form; Form at lowest is just one grade higher than Matter. If a thing is a good to itself, much more must its perfection, its Form, its better, be a good to it
Plotinus places matter at the lowest rung of ontological value and form as the good toward which matter tends, embedding the dyad within his axiology of degrees of being.

it is the prime matter of all bodies, and through it, they say, complete and universal reason passes, just like seed through the genital organs. This reason they take to be an actual craftsman, while the cohering body they take to be without quality, i.e. matter or substance, completely passive and subject to change.
The Stoics recast the form-matter dyad as active reason (logos) passing through passive, qualityless matter, offering a pneumatic-cosmological alternative to Aristotelian hylomorphism.

Matter is a form of Spirit, a habitation of Spirit, and here in Matter itself there can be a realisation of Spirit. It is true again that Life when it emerges becomes dominant, turns Matter into an instrument for its manifestation
Aurobindo dissolves the opposition of form and matter into a spiritual evolutionism in which matter is itself a form of Spirit, anticipating its own transformation into a vehicle of divine manifestation.

Body must necessarily be a plurality, since all bodies are composite of Matter and Quality. If however body in this case is to be understood in some different way, then Matter is identified with body only by an equivocation.
Plotinus scrutinizes Stoic and materialist accounts that make matter a first-principle, arguing that any body is composite and that identifying matter with body is an equivocation.

the duality between the conditions of the attribution of this principle to form or to matter is rediscovered in the very content of the notion. Without researching the principle of individuation, the following question can be posed: what is individuation?
Simondon shows that the philosophical question of individuation is itself structured by the form-matter duality, making the dyad not merely a metaphysical relic but a live epistemological problem.

the older creeds, more patient, more broodingly profound, not touched with the torture and the feverish impatience of the soul under the burden of the Iron Age, did not make this formidable division; they acknowledged Earth the Mother and Heaven the Father
Aurobindo situates the hostile dualism of matter and spirit in historical-cultural context, noting that older traditions maintained a more integral relationship between the material and the formal-spiritual.

to essential existence would be opposed the non-existence; to the nature of Good, some principle and source of evil. Both these will be sources, the one of what is good, the other of what is evil
Plotinus's discussion of the primal contrariety between Good and Evil implicitly frames matter as the principle of privation and evil, contextualizing its role in the form-matter hierarchy.
