Phantasy — alternately spelled 'fantasy' in post-Jungian usage — occupies one of the most contested territories in the depth-psychological corpus, traversing clinical, philosophical, and ontological registers simultaneously. Freud's foundational contribution establishes the term in its double valence: phantasy is neither pure fabrication nor literal memory, but a psychical formation that erects itself upon the scaffolding of real experience, becoming the immediate fore-runner of hysterical symptoms and the intermediate station on the path to symptom-formation via introversion of the libido onto previously harmless psychical products. Klein radicalises this by rendering unconscious phantasy the very medium of the infant's object-relations — phantastic elements permeating every external experience and shaping the ego's structure through splitting, introjection, and projection. Lacan inherits the clinical problem and formalises it in the matheme $ ◇ o, insisting that the subject is constitutively suspended within phantasy rather than external to it; his reading of Klein's theory as requiring precisely this correction marks a decisive structural turn. Samuels notes the proximity — though not identity — of Kleinian unconscious phantasy to Jung's archetypal theory. Aristotle's phantasia, treated through Lorenz, provides a pre-psychoanalytic anchor: a faculty mediating between perception and desire, indispensable for locomotion and non-rational motivation. Across all traditions, phantasy stands at the intersection of representation, desire, and reality-testing.
The return of the libido on to phantasy is an intermediate step on the way to symptom-formation which well deserves a special designation. C. G. Jung has coined for it the very appropriate name of INTROVERSION
Freud identifies the libido's regression onto phantasy as the pivotal mechanism in symptom-formation, simultaneously marking the conceptual boundary between his use of 'introversion' and Jung's broader application of the term.

The study of the neuroses leads to the surprising discovery that these phantasies are the immediate fore-runners of hysterical symptoms... Hysterical symptoms are not attached to memories, but to phantasies erected on the basis of memories.
Freud establishes phantasy — including the day-dream — as the structural precursor to hysterical symptom-formation, displacing raw memory as the operative pathogenic material.

in the young infant's mind every external experience is interwoven with his phantasies and on the other hand every phantasy contains elements of actual experience
Klein articulates phantasy as the inescapable medium of early object-relations, dissolving any clean boundary between inner phantastic elaboration and outer reality in infantile psychic life.

the whole key to the correction required by the theory of phantasy in Melanie Klein is entirely in the symbol that I give you of the phantasy $ ◇ o, which can be read as: S barred desire of o
Lacan presents his matheme of phantasy as the structural correction to Kleinian theory, formalising the subject's constitutive capture within phantasy as the relation of barred desire to the object a.

it is no phantasy but a real remembrance; fortunately, however, it is still not as often real as it seemed at first... the phantasy is usually employed to cover the childhood period of auto-erotic sexual activity
Freud negotiates the epistemological problem of distinguishing phantasy from memory in clinical reconstruction, showing how phantasy typically serves as a retrospective screen over auto-erotic origins.

the phantasies and feelings about the state of the internal object vitally influence the structure of the ego. The more sadism prevails in the process of incorporating the object... the more the ego is in danger of being split
Klein demonstrates that unconscious phantasy is not merely representational but constitutively formative, as the quality of phantasied object-states directly determines ego-structure through sadism and splitting.

It is Klein's notion of unconscious fantasy, however, that is the psychoanalytic idea most closely aligned with archetypal theory.
Samuels identifies Kleinian unconscious fantasy as the psychoanalytic concept with the strongest structural affinity to the Jungian archetype, while insisting the two are nonetheless not equivalent.

the childhood-experiences reconstructed or recollected in analysis are on some occasions undeniably false, while others are just as certainly quite true, and that in most cases truth and falsehood are mixed up
Freud confronts the irreducible epistemological ambiguity of clinical phantasy-material, establishing that phantasy and historical truth are systematically entangled rather than cleanly separable.

analytic concern with phantasies does not imply a disinterest in reality; rather, by following a phantasy, a distant occurrence or a suppressed reality can be explored.
Against reductive readings, this passage argues that clinical engagement with phantasy is precisely the route to suppressed or dissociated reality, reaffirming phantasy's diagnostic and epistemic function.

By fantasy in the sense of fantasm I mean a complex of ideas that is distinguished from other such complexes by the fact that it has no objective referent... it is merely the output of creative psychic activity
Jung distinguishes between fantasy as fantasm — a psychic product without external referent — and fantasy as imaginative activity, grounding a typological distinction central to his psychology.

In selecting examples of dream-interpretation I have so far avoided dreams in which unconscious phantasies play any considerable part... they often make their way complete into dreams
Freud acknowledges the structural role of unconscious phantasies as dream-building elements that can traverse censorship and appear relatively intact in manifest dream content.

phantasia [sc. suitably prepares] desire; and phantasia arises through thought or through perception... whether or not thought or perception is involved, phantasia in any case plays a role in the process
Lorenz explicates Aristotle's account of phantasia as the indispensable mediating faculty between perception or thought and desire in the production of purposive animal movement.

Lorenz shows that for Aristotle phantasia shares its object-range with perception, giving it a broadly sensory character that encompasses the diversity of appearances guiding animal behaviour.

for animals which are capable of locomotion, what imparts locomotion to them is the capacity for desire acting in concert with the capacity for phantasia
Lorenz identifies the Aristotelian conjunction of desire and phantasia as the necessary and sufficient condition for animal self-locomotion, making phantasia structurally irreducible in motivational theory.

perception and, in particular, phantasia, as he conceives of them, can, or anyhow are meant to be able to, account for an animal's ability to envisage prospects that are suitable to its circumstances
Lorenz argues that Aristotle's phantasia must be credited with enabling animals to form contextually appropriate prospective representations, thereby explaining adaptive motivated behaviour.

this leaves the I well in suspense, it leaves it so well stuck in any case in phantasy that I would defy you, to find this I of desire elsewhere than where M. Genet highlights it
Lacan argues that desiring subjectivity is structurally entrapped within phantasy, such that the 'I' of desire cannot be located outside the phantasmatic frame.

the sensation of the introvert, which is usually sentimental, has a very strong tinge of unconscious fantasy. The third element, in which the opposites merge, is fantasy activity, which is creative and receptive at once.
Jung links repressed inferior functions with unconscious fantasy-colouration, and identifies fantasy activity as the synthetic 'third' that mediates between psychic opposites.

In his dreamings he was the energetic, despotic man, but afterwards he changed back into the weak and dependent 'child'. The poems of his schooldays formed a suitable interruption of his phantasies
Abraham documents phantasy as a sustained compensatory structure in which the patient inhabits an idealized self-image, the interruption of which precipitates regression to infantile dependence.

the retention of such affections requires that disturbances created by acts of perception are in some way or other preserved in the animal's perceptual apparatus... they generate sensory experiences
Lorenz details the physiological substrate of Aristotelian phantasia as residual perceptual disturbances preserved in the sense-organs, generating dream-like appearances and memory-traces.

the realisation of his phantasy in some form or other, it seems that people have never dwelt on the function which is quite important
Lacan notes a neglected clinical observation: that the obsessional's self-analytic path toward the realisation of his phantasy involves a specific and under-theorised function in the structure of desire.

the habituation of juvenile deer can be seen to equip them with appropriately complex representations that are preserved in their perceptual apparatus, so as to guide their speedy return to the lair
Lorenz uses ethological examples to demonstrate that Aristotle's phantasia must be capable of preserving complex, action-guiding representations across time in non-human animals.
