Within the depth-psychology corpus, feces occupies a surprisingly rich conceptual territory that extends well beyond mere bodily waste. The classical Freudian lineage — represented here by Abraham, Freud, and their developmental successors — establishes feces as the child’s first piece of private property, the original object of anal-erotic economy, and a symbolic currency homologous with money, gift, and retained possession. Abraham in particular elaborates the unconscious equation of expelling feces with the psychic ejection of a love-object, linking anal-sadistic organization to obsessional character, melancholia, and manic states. Hillman, writing from an archetypal vantage, reclaims this material differently: diarrhea becomes a movement into the underworld, the Greek borborygmus connecting intestinal rumblings to the filthy mire of Hades, while the child’s polymorphous delight in bodily products belongs to a broader Dionysian sensibility. Grof situates feces within the perinatal matrices, where coprophilic imagery signals the crushing encounter with birth biology and the paradoxical relief attending biological contact. Greene, in a more pedagogical register, traces toilet training as the crucible where creative self-production first meets social shame. Across all these positions, feces functions as a threshold substance — liminal between interior and exterior, self and world, creation and abjection — and its symbolic weight in clinical, archetypal, and transpersonal frameworks is consistently underestimated when treated as mere regression.
