The soul-body distinction stands as one of the most generative and contested problematics within the depth-psychology corpus, traversing ancient metaphysics, Renaissance Neoplatonism, Cartesian dualism, phenomenology, and archetypal psychology with equal force. Plotinus provides the philosophically most rigorous ancient treatment, arguing systematically that soul is incorporeal precisely because it accomplishes what body cannot: integral self-identity across extension, whole traversal of another whole, and intellection independent of sensory apparatus. Hillman inherits this Neoplatonic inheritance but radicalizes it: he refuses the literalism of spatial location while insisting that soul's 'in-ness' is an imaginal rather than anatomical fact, and he traces the modern impoverishment of psychological life to the conciliar reduction of a tripartite cosmos — spirit, soul, body — to mere dualism. Bulgakov, writing from Eastern Orthodox sophiology, uses the spirit-body relation within the human person as an analogy for divine hypostatic life, treating the body as the spirit's icon and creation rather than its prison. Descartes stands at the structural hinge, institutionalizing the very mind-body binary that subsequent depth-psychological thinkers most strenuously resist. Merleau-Ponty and Thompson press back from phenomenology and biology, insisting that subjectivity and feeling are irreducibly bodily phenomena. Bremmer's historical ethnography traces the distinction between 'free soul' and 'body soul' in early Greek thought, showing it to be culturally variable and porous. Together, these voices reveal the soul-body distinction as less a settled doctrine than a living tension whose resolution — or deliberate suspension — determines the entire shape of a psychology.
intellection is apprehension apart from body, much more must there be a distinction between the body and the intellective principle: sensation for objects of sense, intellection for the intellectual object.
Plotinus grounds the soul-body distinction in an epistemological argument: because intellection transcends sensation and the body is partite while the sentient principle must be self-identical throughout, soul cannot be any form of body.

our anthropology, our idea of human nature, devolved from a tripartite cosmos of spirit, soul, and body (or matter), to a dualism of spirit (or mind) and body (or matter).
Hillman locates the historical catastrophe of modern psychology in the ninth-century conciliar reduction of the tripartite anthropology — spirit, soul, body — to a binary dualism, arguing that the loss of soul as a distinct third term is the root of the modern psychological predicament.

The sense of 'in-ness' refers neither to location nor to physical containment. It is not a spatial idea, but an imaginal metaphor for the soul's nonvisible and nonliteral inherence, the imaginal psychic quality within all events.
Hillman dissolves the spatial literalism that has haunted the soul-body distinction — pineal gland, humors, neural tissue — by reframing soul's interiority as an imaginal, not anatomical, quality.

The body should be understood as a revelation of the spirit, of its likeness and of its life. Being informed by intelligence, it provides the outward expression for human individuality — it is, so to speak, an icon of the spirit which dwells in it.
Bulgakov, using the human spirit-body relation as a theological analogy, reframes the body not as brute matter opposed to soul but as the spirit's self-revelation and icon, a move that subordinates Cartesian dualism to sophiological participation.

body cannot traverse anything as a whole traversing a whole. But soul does this. It is therefore incorporeal.
Plotinus offers a geometric demonstration of soul's incorporeality: because body cannot traverse another body whole through whole without infinite divisibility, and soul does precisely this, soul must be ontologically distinct from body.

Pleasure and distress, fear and courage, desire and aversion, where have these affections and experiences their seat? Clearly, either in the Soul alone, or in the Soul as employing the body, or in some third entity deriving from both.
Plotinus opens the Enneads by posing the soul-body distinction as a structural question about the locus of affection, establishing three possible ontological configurations that organize all subsequent Neoplatonic psychology.

The problem of what it is for mental processes to be also bodily processes is thus in large part the problem of what it is for subjectivity and feeling to be a bodily phenomenon.
Thompson, drawing on phenomenology and biology, reframes the soul-body distinction as the problem of how subjectivity — feeling, experience — can be simultaneously and irreducibly a bodily phenomenon, rejecting Cartesian bifurcation without collapsing into eliminative materialism.

the Soul of the Universe cannot be in bond to what itself has bound: it is sovereign and therefore immune of the lower things, over which we on the contrary are not masters.
Plotinus distinguishes the cosmic Soul's ontological freedom from bodily entanglement from the human soul's condition of being doubly fettered — first by the body-kind's capture within the All-Soul, then by the imprisoning grip of individual embodiment.

The body and consciousness are not mutually limiting, they can be only parallel. Any physiological explanation becomes generalized into mechanistic physiology, any achievement of self-awareness into intellectualist psychology.
Merleau-Ponty argues that the Cartesian soul-body distinction generates an irresolvable explanatory impasse: assigning some movements to bodily mechanism and others to consciousness is incoherent, since the two domains can be only parallel, not interactive.

animals that, originally, were supposed to exist inside the living body, like the mouse... seem to represent the body souls. This distinction creates at least some order in a seemingly chaotic world.
Bremmer's ethnographic analysis of early Greek and comparative evidence reveals that the soul-body distinction was originally articulated as a polarity between 'free souls' — representing personal identity when the body is inactive — and 'body souls' — the vital animating principles immanent within the living organism.

The soul, sprung from the divine, lay self-enclosed at peace, true to its own quality; but its neighbour, in uproar through weakness, instable of its own nature and beaten upon from without, cries... spreading the disorder at large.
Plotinus dramatizes the soul-body relation as a political asymmetry: the soul, divine in origin and self-sufficient in nature, is troubled not from within but by the body's constitutive instability, which imposes disorder upon the composite living being.

We may regard anger or fear as such and such movements of the heart, and thinking as such and such another movement of that organ, or of some other; these modifications may arise either from changes of place in certain parts or from qualitative alterations.
Aristotle complicates a sharp soul-body dualism by treating affective states as simultaneously movements of the soul and physiological processes of specific organs, anticipating the hylomorphic unity of the compound that later commentators will use against Cartesian bifurcation.

Gassendi ironically addresses Descartes as 'O soul' since he identifies himself with the soul as distinct from the body... Whether or not the soul is, as Gassendi suggests, a 'subtle' body, he argues that it needs the help of the solid body in order to think.
Gassendi's objection to Descartes — that even a 'subtle' soul requires the solid body in order to think — surfaces the central vulnerability of Cartesian dualism and opens the path toward both phenomenological and depth-psychological reformulations.

Soul, conceived apart from affection and Reason-Principle, we have restored to its origin, leaving in the lower realm no substance which is in any sense Intellectual.
Plotinus insists on a principled distinction between psychic and bodily qualities, restoring pure soul to its transcendent origin while assigning bodily affections to the lower sensible realm, thus maintaining ontological asymmetry against any collapse of the two into one substance.

the real and unwavering (aei) philosopher remains for every free from the body. That at least...
Rohde traces in Platonic thought the culminating aspiration of the soul-body distinction: the philosopher who has achieved genuine purification escapes the cycle of rebirth altogether, realizing the fullest possible separation from body as the soul's proper telos.

I believe their identity is more pronounced when soul and spirit have not been discriminated; then anima is exaggeratedly mercurial, less the container than seductively elusive — all over the place.
Hillman notes that the confusion of soul with spirit — rather than with body — produces a distinct pathology of the anima: when soul and spirit are undiscriminated, the soul becomes volatile and uncontained, losing its distinctive depth-giving function.

if we do not allot to each of the parts of the Soul some form of Place, but leave all unallocated — no more within the body than outside it — we leave the body soulless, and are at a loss to explain plausibly the origin of acts performed by means of the bodily organs.
Plotinus confronts the practical aporia generated by the soul-body distinction: an utterly non-spatial soul cannot account for embodied action, yet a spatially located soul becomes partite and thus forfeits its defining indivisibility.
