Instinct occupies a foundational and contested position throughout the depth-psychology corpus. Jung provides the most architecturally elaborate treatment, situating instinct at the boundary between the somatic and the psychic: it is neither purely biological nor purely mental, but a liminal force whose modification by psychic processes produces what he calls 'psychization.' His enumeration of five basic instincts — hunger, sexuality, the drive to activity, reflection, and creativity — establishes a taxonomy that later Jungians such as Hillman and Samuels refine and debate. Crucially, Jung places instinct and archetype on a single continuum, the infrared and ultraviolet poles of the same psychic spectrum: the archetype is, in one formulation, 'the instinct's perception of itself.' Freud anchors the concept differently, defining instinct as the psychical representative of a continuous endosomatic stimulus — a measure of demand made upon the mind for work. Levine extends the biological grounding into trauma theory, arguing that disconnection from instinctual life underlies somatic pathology. Estés frames injured instinct as the wound inflicted by cultural captivity upon women's wild nature. Hillman reads the Panic suppression of instinct as civilizational hubris. Across all these positions the central tension remains: instinct as raw compulsion demanding subordination versus instinct as irreplaceable intelligence demanding integration.

an 'instinct' is provisionally to be understood the psychical representative of an endosomatic, continuously flowing source of stimulation... The concept of instinct is thus one of those lying on the frontier between the mental and the physical.
Freud establishes the canonical psychoanalytic definition of instinct as a borderline concept between soma and psyche, distinguished from external stimuli by its continuous, internally arising pressure.
Freud, Sigmund, Three Essays on the Theory of Sexuality, 1905thesis
the immediate determining factor is not the ectopsychic instinct but the structure resulting from the interaction of instinct and the psychic situation of the moment. The determining factor would thus be a modified instinct.
Jung argues that what actually governs behavior is never raw instinct but instinct as transformed by its encounter with psychic context — a 'modified instinct' shaped by the moment.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960thesis
with increasing freedom from sheer instinct the partie superieure will ultimately reach a point at which the intrinsic energy of the function ceases altogether to be oriented by instinct in the original sense, and attains a so-called 'spiritual' form.
Jung traces a developmental arc from instinctual compulsion toward spiritual freedom, arguing that the energy remains the same while its mode of application transforms.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960thesis
Jung places images and instinct on a psychological continuum, like a spectrum... ranging from an infrared end, the bodily action of instinctual desire, to the ultraviolet blue end of fantasy images.
Hillman explicates Jung's spectrum model in which instinct and image are polar expressions of the same psychic energy, directly contrasting this with Freud's sublimation model.
There is another instinct, different from the drive to activity and so far as we know specifically human, which might be called the reflective instinct... the reflex which carries the stimulus over into its instinctive discharge is interfered with by psychization.
Jung introduces the 'reflective instinct' as uniquely human — the capacity to bend back from immediate discharge — and identifies psychization as the mechanism by which this interference occurs.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960thesis
the 'intuition' which brings the instinct into play, in other words the apprehension by means of the archetype, must be something incredibly precise... the yucca moth must carry within it an image, as it were, of the situation that 'triggers off' its instinct.
Jung uses the yucca moth as his paradigmatic illustration that instinctual release requires an internal image — the archetype — functioning as a perceptual template that 'recognizes' the releasing situation.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960thesis
He regards the instincts as older than, prior to, and outside the... [psyche]
Hillman summarizes Jung's foundational claim that instincts are phylogenetically anterior to psyche, establishing the ontological priority of instinct over conscious life.

Jung goes on to describe five basic instinctual groups which he calls, in short: hunger, sexuality, the drive to activity, reflection, and, last of all, a creative instinct.
Hillman catalogues Jung's five-instinct taxonomy and maps it onto Lorenz's ethological categories, noting that creativity appears only in the human register.

Instincts are usually taken to mean deeply embedded drives that do not have to be learnt, are not pursued as conscious aims, and find their fulfilment directly in their expression.
McGilchrist offers a philosophically precise characterization of instinct as pre-conscious, non-teleological, and self-fulfilling, situating it within a broader argument about non-Western epistemologies of tacit knowing.

the 'primordial image might suitably be described as the instinct's perception of itself'... the yucca moth must carry within it an image of the yucca plant that 'triggers off' the instinctual response.
Hogenson foregrounds Jung's most compressed formulation of the archetype-instinct relationship — primordial image as instinct's self-perception — in the context of evolutionary cognitive neuroscience.

the yucca moth must carry within it an image, as it were, of the situation that 'triggers off' its instinct. This image enables it to 'recognise' the yucca flower and its structure.
Samuels contextualizes Jung's yucca moth paradigm within post-Jungian reception, connecting it to Fordham's parallel with Tinbergen's innate release mechanisms in ethology.

Hercules, who cleaned up Pan's natural world first, clubbing instinct with his will-power, does not stop to clear away the dismembered carcasses left to putrefy after his civilizing, creative tasks.
Hillman reads the figure of Hercules as the mythic avatar of will-power's assault on instinct, identifying the suppression of Pan with the severing of personified nature from psychic life.

the uniformity of the phenomenon and the regularity of its recurrence which are the most characteristic qualities of instinctive action... it would be as uninteresting to bet on an instinctive reaction as on the rising of the sun tomorrow.
Jung distinguishes instinct from compulsion and phobia by its criterion of universal recurrence, borrowing Lloyd Morgan's formulation to establish predictability as the hallmark of genuine instinctual process.

We think of instinct as uniting man, causing him to mate, to beget, to seek pleasure and good living... We forget that this is only one of the possible directions of instinct. There exists not only the instinct for the preservation of the species, but also the instinct of self-preservation.
Jung contests the reductive identification of instinct with social bonding and sexuality, insisting that the will to self-preservation and power constitutes an equally primary instinctual direction.

The conflict between ethics and sex today is not just a collision between instinctuality and morality, but a struggle to give an instinct its rightful place in our lives, and to recognize in this instinct a power which seeks expression and evidently may not be trifled with.
Jung reframes the ethics-sexuality conflict not as instinct's subjugation but as its rightful integration, insisting that instinct carries legitimate claims that moral legislation cannot simply override.

This denial of the instinctual life is also shared by strange bedfellows, many modern behavioral scientists... In all cultivation, native instinct is the most difficult force to remember and take into account.
Levine diagnoses the denial of instinctual life as a shared failure of religious conservatism and behavioral science alike, grounding his somatic trauma theory in the recovery of animal nature.

the religious impulse rests on an instinctive basis and is therefore a specifically human function. You can take away a man's gods, but only to give him others in return.
Jung grounds the religious impulse in instinct, arguing that its suppression by the mass State does not eliminate it but displaces its energy onto secular substitutes charged with demonic force.

The combination of raw instinct and artful shaping is also found in human mating rituals... one must beware of what has been called 'zoomorphism'—the uncritical extension of conclusions drawn from animal behavior to humans.
Levine explores the continuity between animal instinct and human ritual form, using the tango and scorpion mating dance as parallel structures while warning against uncritical zoomorphism.

Embodiment is about gaining, through the vehicle of awareness, the capacity to feel the ambient physical sensations of unfettered energy and aliveness... it paradoxically allows instinct and reason to be held together, fused in joyful participation and flow.
Levine presents embodied awareness as the somatic practice by which instinct and reason are integrated rather than opposed, resolving the Cartesian split through sensory attention.

the primary, aggressive sex instinct and the social mating instinct... Only in isolated and exceptional cases is the sexual instinct carried so far towards absurdity that the male eats the female he has fertilized.
Neumann employs Briffault's distinction between aggressive and social sexual instincts to illuminate the uroboric archetype's alimentary dominance over sexuality in the presexual developmental stage.

the theory of human instincts finds itself in a rather delicate situation, because it is uncommonly difficult not only to define the instincts conceptually, but even to establish their number and their limitations.
Jung acknowledges the fundamental theoretical difficulty of instinct theory — the problem of delimiting and enumerating instincts — while affirming that they possess both physiological and psychological aspects.

We could call sexuality the spokesman of the instincts... For just as the spirit would press sexuality, like every other instinct, into its service, so sexuality has an ancient claim upon the spirit.
Jung positions sexuality as the representative voice of the instincts as a whole, arguing for a reciprocal rather than hierarchical relationship between spirit and instinctual life.
Jung, C. G. and Pauli, Wolfgang, The Interpretation of Nature and the Psyche, 1955supporting
the lower reaches of the psyche begin where the function emancipates itself from the compulsive force of instinct and becomes amenable to the will, and we have defined the will as disposable energy.
Jung locates the boundary between instinct and psyche precisely at the point where compulsive instinctual discharge gives way to voluntary deployment of libidinal energy.
