Exogamy enters the depth-psychology corpus primarily through Freud's sustained engagement in Totem and Taboo (1913), where the institution is situated at the contested intersection of totemism, the incest taboo, and the psychoanalytic reconstruction of prehistoric social life. Freud rehearses the anthropological debate — whether exogamy is integral to totemism or merely adventitiously convergent with it — and grounds both institutions in the dynamics of the primal horde, deriving the prohibition on sexual relations within the totem-clan from the jealous interdictions of the primal father, as theorized through Darwin and J.J. Atkinson. Jung, in The Practice of Psychotherapy and Aion, transposes the social fact of exogamy into a psychological register: the institution becomes the external correlate of an endopsychic antithesis between ego and anima, between the endogamous longing for the familiar and the exogamous necessity of encountering the genuinely other. Neumann, in The Origins and History of Consciousness, reads exogamy's matriarchal variant as structurally dispersing the male and reinforcing the autonomy of the female group. Across these texts a persistent tension obtains: exogamy is simultaneously a sociological datum requiring historical explanation and a symbolic enactment of the psyche's own movement from incestuous fixation toward the transformative encounter with the stranger.
the practical consequence of the conditions obtaining in Darwin's primal horde must be exogamy for the young males... 'No sexual relations within the totem.'
Freud derives exogamy as a necessary social consequence of the primal horde's dynamics, tracing it from biological necessity to conscious law to totemic prohibition, while noting the unresolved question of whether exogamy preceded or was derived from totemism.

The attitude taken by an author on the problems of exogamy must naturally depend to some extent on the position he has adopted towards the various theories of totemism.
Freud maps the field of scholarly dispute, identifying two irreconcilable positions — exogamy as intrinsic to totemism versus exogamy as accidentally convergent with it — as the central fault line in the anthropological literature.

The matriarchal system of exogamy hinders the formation of male groups, because the men are obliged to marry outside their tribe and thus get dispersed, having to live matrilocally, as strangers in the wife's tribe.
Neumann reads matriarchal exogamy as a structural mechanism that preserves female group autonomy by enforcing the dispersal and social alienation of the male, preventing the consolidation of patriarchal bonding groups.

She is the natural sponsa, man's mother or sister or daughter or wife from the beginning, the companion whom the endogamous tendency vainly seeks to win in the form of mother and sister.
Jung contrasts the endogamous tendency — the psychic drive toward the familiar feminine — with the exogamous reality that has historically enforced its sacrifice, framing exogamy as the social institution through which the anima becomes internalized rather than projected outward.

one of the two principal taboos, that of exogamy, is not mentioned at all... 'the rule that a man may not kill or eat his totem animal or plant; and second, the rule that he may not marry or'
Freud identifies exogamy as one of the two constitutive taboos of totemism — alongside the prohibition on killing the totem — establishing it as structurally central to primitive social and religious organization.

the arrangement took a form that derives from the primitive cross-cousin marriage, namely the marriage quaternio. This differs from the primitive form in that the sister-exchange marriage has sloughed off its biological character.
Jung traces the Gnostic marriage quaternio back to the structure of cross-cousin marriage — a form of regulated exogamy — arguing that the psyche recapitulates this social schema as an organizing archetype of quaternity.

The social split is by origin a matrilineal division into two, but in reality it represents a division of the tribe and settlement into four. The quartering comes about through the crossing of the matrilineal by a patrilineal line of division.
Jung interprets the tribal moiety system — the social infrastructure presupposing exogamic exchange — as a projection of the psyche's fundamental split between conscious and unconscious, masculine ego and feminine anima.

the tangle of relationships in the cross-cousin marriage reappears in the transference problem... anima and animus are projected upon their human counterparts and thus create by suggestion a primitive relationship which evidently goes back to the time of group marriages.
Jung proposes that the transference situation psychologically recapitulates the relational structure of exogamic cross-cousin marriage, with anima and animus projection reproducing the archaic entanglement of regulated group exchange.

Jung suggested that the psychologically regenerating endogamous tendency (the symbolic attempt to marry within the family) must be considered as a genuine instinct and not as a perversion.
Samuels articulates the Jungian dialectic between endogamy and exogamy, framing their tension as the engine of psychic transformation — the blocked endogamous libido driving spiritualization — which implies exogamy as the necessary counter-pressure.

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, following Frazer, deploys the paradox that the legal enforcement of exogamy — like all taboos — is itself evidence of a powerful opposing wish, implying that the prohibition addresses real incestuous desire rather than a naturally absent one.

the terms used by them to express the various degrees of kinship do not denote a relation between two individuals but between an individual and a group. This is what L. H. Morgan named the 'classificatory' system of relationship.
Freud identifies the classificatory kinship system of Australian tribes as the social-linguistic framework within which exogamic regulations operate, distributing sexual prohibition across entire clan categories rather than individual relations.

how did they come to make the fact of their being descended from one animal or another the basis of their social obligations and, as we shall see presently, of their sexual restrictions?
Freud frames the totemism problem — the origin of both clan solidarity and sexual restriction — as the broader theoretical context within which exogamy must be understood.

The primary splitting of the psyche into conscious and unconscious seems to be the cause of the division within the tribe and the settlement. It is a division founded on fact but not consciously recognized as such.
Jung reframes the tribal moiety structure — the social precondition for exogamic exchange — as an externalization of the psyche's own primary division, grounding the anthropological institution in depth-psychological dynamics.
