The term 'Ideal Form' traverses the depth-psychology corpus along at least three distinct axes that refuse easy synthesis. In the Neoplatonic strand, anchored by Plotinus, Ideal Form denotes an ontological category — a self-subsistent, impassible principle whose mere presence generates activity in matter while remaining itself untouched by any affection; it is the tranquil engine of all vegetal, psychic, and intellectual life. Plato's Timaeus supplies the geometrical and cosmological substrate for this vision, treating elemental forms as the irreducible structural determinants of physical reality. A second axis, biological-psychological, appears in Barrett's critique of pre-Darwinian essentialism: the 'ideal form' of each species served as the normative template against which individual variation was measured as error — a paradigm that post-Darwinian science dismantled but that, Barrett argues, covertly persists in classical emotion theory. A third axis is psychoanalytic and developmental: Schore, Cairns, and related authors locate the ego-ideal as an internalized cluster of ideal-form images whose failure to be met by the self produces shame and regulates self-esteem. Aurobindo's contribution is philosophically the most ambitious, reading the Ideal as an eternal Reality already held in divine Real-Idea, toward which evolving mind grows. Simondon's process-ontological treatment complicates all these positions by challenging the hylemorphic framework itself, arguing that form is never a finished mold but a dynamic limit on the actualization of potential energy. The stakes across all positions concern whether Ideal Form is discovered, imposed, or emergent.
No Ideal-form can be the victim of disturbance or be in any way affected: it remains in tranquillity; only the Matter associated with it can be affected by any state or experience induced by the movement which its mere presence suffices to set up.
Plotinus establishes the axiomatic Neoplatonic doctrine that Ideal Form is ontologically impassible — an activity-by-presence that moves all things while itself remaining unmoved.

Let us then suppose Soul to be in body as Ideal-Form in Matter. Now if — the first possibility — the Soul is an essence, a self-existent, it can be present only as separable form and will therefore all the more decidedly be the Using-Principle [and therefore unaffected].
Plotinus deploys the Ideal Form/Matter relation as the governing analogy for the Soul-body relation, establishing the separability and priority of form over material substrate.

The Intellectual-Principle and the Soul, being Ideal-Forms, would know Ideal-Forms and would have a natural tendency towards them; but who could imagine Evil to be an Ideal-Form, seeing that it manifests itself as the very absence of Good?
Plotinus argues that knowledge proceeds by formal likeness, so the Intellectual-Principle's cognition of Good is grounded in its own status as Ideal Form — Evil, lacking this status, can only be known derivatively as privation.

The type of all perfection towards which we grow, the terms of our highest evolution must already be held in the divine Real-Idea; they must be there formed and conscious for us to grow towards and into them: for that pre-existence in the divine knowledge is what our human mentality names and seeks as the Ideal.
Aurobindo reframes Ideal Form as an eternally pre-existent pattern within divine Real-Idea, constituting the teleological attractor of human mental and spiritual evolution.

Each species was assumed to have an ideal form, created by God, with defining properties (essences) that distinguished it from all other species. Deviations from the ideal were said to be due to error or accident.
Barrett identifies the pre-Darwinian 'ideal form' as the essentialist norm against which individual variation was classified as error, a paradigm she traces as the hidden epistemic ancestor of classical emotion categories.

The superego affect of shame has been conceptualized as the affect that arises when a self-monitoring and evaluating process concludes that there has been a failure to live up to ego ideal images... The internal set of expectations that are part of the ego ideal form a 'global gestalt' and the image of the ideal self has an 'intensely visual' character.
Schore integrates the ego-ideal-as-Ideal-Form into neurobiological affect-regulation theory, showing that shame emerges precisely from the measured distance between actual self and internalized ideal image.

Are they not patterns to which we liken our actions and ourselves? This gives rise to the doctrine that the philosopher 'imitates the objects that are' and 'likens himself to them' and finally likens himself to God.
Havelock examines the mimetic relation to Platonic Forms, noting that the philosopher's self-likening to Ideal Forms risks collapsing into the very imagistic, performative register Plato elsewhere critiques.

The form does not evolve and is not modified because it does not contain any potentiality, whereas the matter evolves. The matter is the bearer of potentialities that expand and are distributed uniformly in it.
Simondon critiques the classical hylemorphic model by arguing that Ideal Form's impassibility is not a virtue but a theoretical deficit — form without potentiality cannot account for the dynamic reality of individuation.

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.
Simondon reconceives Ideal Form operationally as an informing boundary-condition that channels but does not itself carry the energetic transformation central to individuation.

The ego-ideal is formed by the internalization of the ideals of loving parents and reinforced by identification with the sibling and peer groups... shame accompanies failure because it is concerned with goals and ideals, and for it to be concerned with goals and ideals is for it to be a function of the ego-ideal.
Cairns situates the ego-ideal as the psychoanalytic successor to the concept of Ideal Form, arguing that shame's function is structurally inseparable from the measuring of actual conduct against internalized ideal standards.

The self that one should become is not something static and final; it is, rather, the dynamic expression of the will to power itself... Such passages call to mind the thumos' tendency to create an ideal self-image and strive to live up to it.
Hobbs connects Nietzsche's dynamic self-ideal to the classical thumic drive toward an ideal self-image, complicating the static Platonic Form with a becoming-oriented, agonistic variant.

The soul names as from an ancient knowledge and, recognising, welcomes it, enters into unison with it... the soul — by the very truth of its nature, by its affiliation to the noblest Existents in the hierarchy of Being — when it sees anything of that kin, or any trace of that kinship, thrills with an immediate delight.
Plotinus describes the soul's anamnetic recognition of beauty as evidence of its formal kinship with the highest Ideal-Form-level of Being, grounding aesthetic response in ontological affiliation.

Not only is it evident from this self-immortalization in the work that the matter is at bottom one of self-immortalization expressed in another (in the ideal), but both these artists have expressed with great clearness, and to the point of monotony, the idea of oneness with the friend.
Rank treats the beloved as an ideal form onto which the artist projects and seeks to eternalize the self, linking the Platonic aspiration toward ideal beauty with the dynamics of creative narcissism.
