Across the depth-psychology corpus, 'organ' operates simultaneously as anatomical fact, psychological metaphor, and spiritual instrument. The term traverses at least four distinct registers. In the Aristotelian-Platonic lineage, the sense organ is rigorously distinguished from the sensing power itself: the organ is the spatial locus 'in which ultimately such a power is seated,' never identical to the ratio or capacity it houses. Adler, as interpreted by Hillman, transforms this anatomical frame into psycho-somatic hermeneutics: the 'inferior organ' generates an 'organ dialect,' a symptomatic language through which the soul discloses its most potent creative possibilities precisely at its weakest anatomical site. Corbin introduces a third register entirely: in Sufi and Ismailian mystical physiology, 'subtle organs' — the lata'if — are suprasensory centers of graduated luminosity, each corresponding to a level of spiritual cognition, rendering 'organ' the very instrument of theophanic perception. Neumann and Simondon extend the concept into biophilosophical ontology, where the organ belongs to the self-organizing system by which consciousness individuates from biological life. The central tension across these positions is whether an organ is primarily a physical substratum, a psychological generator, or an epistemological medium for modes of knowing unavailable to ordinary sense.
The inferior organ speaks, there is, what Adler calls, an 'organ dialect,' an 'organ jargon,' that tells us about ourselves once we learn its language.
Hillman, via Adler, argues that the afflicted or inferior organ becomes a psychic symbol and semiotic medium, generating a somatic language through which individual soul-life is both expressed and organized.

By 'an organ of sense' is meant that in which ultimately such a power is seated. The sense and its organ are the same in fact, but their essence is not the same.
Aristotle establishes the foundational ontological distinction between organ as physical location and sense as ratio or power, insisting they are factually co-extensive yet essentially different.

each of these regions or organs is marked by a colored light which the mystic is able to visualize in a state of contemplation and to which he has to learn to be attentive because it informs him as to his own spiritual state.
Corbin describes the subtle organs (lata'if) of Sufi mystical physiology as luminous centers whose colored light serves as a direct indicator of the mystic's spiritual condition, making 'organ' an instrument of self-knowledge beyond sensory perception.

As for the organ which the spiritual perception of symbols presupposes, it motivates the most characteristic chapters of Shi'ite and of Sufi theosophy, dealing with themes that can be subsumed under the title 'prophetic psychology.'
Corbin identifies a dedicated 'organ' of spiritual perception as the central preoccupation of Islamic theosophy, locating esoteric hermeneutics in a faculty beyond ordinary intellect.

Thymos, noos, and psyche as well are separate organs, each having its own particular function.
Snell argues that in Homeric psychology there is no unified soul but a plurality of distinct organs — thymos, noos, psyche — each performing discrete psychic functions without presupposing a governing whole.

Ego consciousness is a sense organ which perceives the... representation takes the form of images, which are psychic equivalents of the physical processes going on in the organs.
Neumann recasts ego-consciousness itself as a sense organ, arguing that psychic images are the functional representatives of somatic organ-processes within the self-regulating control system of consciousness.

The parts of plants in spite of their extreme simplicity are 'organs'; e.g. the leaf serves to shelter the pericarp, the pericarp to shelter the fruit.
Aristotle extends the concept of organ to the entire organized body of living beings, including plants, grounding it in the teleological notion of soul as actuality of a naturally organized body.

since the tastable is moist, it is necessary that the organ for it be neither moist in actuality nor incapable of becoming moist. For the taste is affected in a way by the tastable insofar as it is tastable.
Aristotle argues that the sense organ must be in a state of potentiality with respect to its proper quality, receiving the sensible form without the matter, exemplifying his hylomorphic theory of perception.

flesh is not the ultimate sense-organ; to suppose that it is requires the supposition that on contact with the object the sense-organ itself discerns what is doing the discerning.
Aristotle refutes the identification of flesh as the primary sense organ of touch, insisting the ultimate organ of sensation must be distinguished from its medium.
