Incest occupies a uniquely contested position in the depth-psychology corpus, functioning simultaneously as literal transgression, archetypal symbol, and transformative metaphor. Freud, in ‘Totem and Taboo,’ establishes the horror of incest as the foundation of cultural prohibition, reading both the taboo and the exogamic institution as socially constitutive responses to an underlying and universal desire — a framework Jung explicitly contested. Jung’s reformulation, most fully elaborated in ‘Symbols of Transformation’ and ‘The Practice of Psychotherapy,’ insists that the incest impulse is primarily psychic rather than literal: it signifies the libido’s regression toward origins, a longing for rebirth and renewal that, when blocked by the taboo, is transmuted into spiritual and cultural energy. The alchemical literature, as Edinger demonstrates, encodes this symbolism in the motif of the coniunctio, where incestuous union between sol and luna, king and mother, figures the opus of psychic integration. Hillman, from the archetypal perspective, demands that incest be located first within imagination and myth — among divinities where it is neither compelled nor taboo — before any humanistic or developmental purpose is assigned to it. Samuels surveys post-Jungian elaborations, particularly Stein’s argument that the taboo itself is the generative force, producing consciousness, mystery, and love. Neumann reads incest mythologically as the hero’s swallowing by the mother, a necessary regression preceding solar rebirth. Moore introduces the clinical and existential dimension, attending to how identification with an ‘incest narrative’ may itself constitute a secondary psychological closure. These divergent positions — Freudian, Jungian, alchemical, archetypal, clinical — constitute the field.
Incest as archetypal prevents us from assigning it a purpose before we have bracketed out the various purposes incest and its taboo may serve in the humanistic contexts of biology, sociology, anthropology
Hillman argues that incest must be recognized first as an autonomous archetypal reality, irreducible to biological, sociological, or developmental purposes, and properly located within the mythic imagination of divinities.

Incest symbolizes Jungian with one’s own being, it means individuation or becoming a self, and, because this is so vitally important, it exerts an unholy fascination
Jung redefines incest symbolically as the psyche’s drive toward self-union and individuation, explaining its numinous fascination as a function of its archetypal depth rather than any literal sexual compulsion.

the incest taboo is as natural a phenomenon as the incest impulse and that there is no point in trying to make the one contingent on the other
Samuels, following Stein and Layard, argues that the incest taboo and the incest impulse are coordinate natural phenomena, and that the taboo generates psychological distance, consciousness, and the capacity for truly human love.
, Jung and the Post-Jungians, 1985thesis
the incest taboo prohibits intercourse and therefore the libido that powers incestuous impulses tends to become imperceptibly spiritualised, so that the ‘evil’ incestuous impulse leads to creative, spiritual life
Samuels articulates the Jungian enantiodromia of the incest impulse: blocked at the instinctual level by the taboo, libido undergoes a compensatory swing toward spirituality and creative life.

Incest was the hierosgamos of the gods, the mystic prerogative of kings, a priestly rite, etc. In all these cases we are dealing with an archetype of the collective unconscious
Jung locates the historical forms of incest — sacred marriage, royal privilege, priestly rite — as expressions of a collective unconscious archetype whose influence on conscious life increases with the growth of consciousness.

This struggle is variously represented as the entry into the cave, the descent to the underworld, or as being swallowed — i.e., incest with the mother
Neumann identifies incest with the mother as the mythological equivalent of the hero’s regression into the unconscious, a necessary phase of the dragon fight through which masculine ego-consciousness is won.

the real cause of the wound is the incest-taboo, which cuts a man off from the security of childhood and early youth, from all those unconscious, instinctive happenings that allow the child to live without responsibility
Jung interprets the mythic wound of the solar hero as the psychological consequence of the incest taboo, which severs the individual from unconscious participation mystique and imposes the burden of conscious responsibility.
, Symbols of Transformation, 1952thesis
Incest, as an endogamous relationship, is an expression of the libido which serves to hold the family together. One could therefore define it as ‘kinship libido,’ a kind of instinct which, like a sheep-dog, keeps the family group intact
Jung theorizes incest as the endogamous expression of a ‘kinship libido’ that functions structurally to maintain the family, standing in dialectical tension with the exogamous libido that drives individuals toward strangers.

When the mother is joined with the son in the covenant of marriage, count it not as incest. For so doth nature ordain, so doth the holy law of fate require, and the thing is not unpleasing to God
An alchemical epithalamium cited by Jung naturalizes the mother-son coniunctio as a divinely sanctioned operation of nature, underscoring the symbolic rather than literal register of incest in the opus alchymicum.

The more critical part was to come later, in the final chapter of Psychology of the Unconscious entitled ‘The Sacrifice,’ which dealt with the subject of incest
Murray Stein identifies Jung’s reinterpretation of incest in the ‘Sacrifice’ chapter as the pivotal and heretical break with Freud, the point at which Jung’s theory of libido diverged irrevocably from the Freudian sexual etiology.

these savages are even more sensitive on the subject of incest than we are. They are probably liable to a greater temptation to it and for that reason stand in need of fuller protection
Freud grounds the universality of the incest taboo in a proportional logic: the intensity of the prohibition reflects the intensity of the underlying desire, establishing the taboo as a cultural defense against the incest impulse.

Freud’s incest theory, which Lincoln also espouses, be maintained! If incest can allegedly be found everywhere, we’d have to assume that it once played a truly enormous role in former times
Jung critically contests Freud’s universalist incest theory, arguing that its explanatory over-extension reduces the complexity of cultural phenomena to a single, undemonstrable historical premise.

incest is in keeping with the tangled emotionality of the family background: passion, hatred, murder, nature turned against itself, raging in the womb, dismemberment
Berry reads mythological incest as tonally and symbolically consonant with the self-compounding, ingrowing pathology of the Perseus myth, assigning it a structural poetic function within the family’s recursive horror.

It is not easy to see why any deep human instinct should need to be reinforced by law. There is no law commanding men to eat and drink or forbidding them to
Freud, via Frazer, argues that the very existence of a legal prohibition against incest proves rather than refutes the presence of an underlying impulse, since natural aversions do not require legislative enforcement.

Without denying any of her pain and suffering, would she be able to see through her story of incest? Could she eventually become free to be an individual, rather than the main character in a story
Moore raises the clinical and existential question of whether identification with the ‘incest survivor’ narrative can itself become a form of psychological enclosure, one that forecloses individuation through fundamentalist self-definition.

it is necessary therefore that they enter into it again, to wit, into their mother’s womb, that they may be regenerate or born again, and made more healthy, more noble, and more strong
Edinger presents the alchemical solutio as an incestuous return to the maternal prima materia, a symbolic dissolution into origins that enables the regeneration and strengthening of the transformed substance.

Incest and perversions were no remarkable novelties to me, and did not call for any special explanation. Along with criminality, they formed part of the black lees that spoiled the taste of life
Jung autobiographically records his early indifference to Freudian incest theory, noting that his rural upbringing had already familiarized him with sexual transgression in ways that stripped it of theoretical novelty.

A mother’s sympathetic identification with her daughter can easily go so far that she herself falls in love with the man her daughter loves; and in glaring instances this may lead to severe forms of neurotic illness
Freud traces derivative incestuous dynamics in the mother-in-law relation, illustrating how the incest complex generates neurotic conflict through displaced and partially conscious erotic identifications within the family system.
