Cannibalism occupies a remarkably heterogeneous terrain in the depth-psychology corpus, functioning simultaneously as a developmental stage, a ritual archetype, a mythological motif, and a marker of civilizational boundary. Freud and Abraham ground the concept in libido theory, treating the oral-cannibalistic phase as the earliest and most archaic organization of erotic life, one whose traces persist in melancholia, mourning, and introjection. Abraham in particular argues that the individual’s cannibalistic libidinal stage mirrors the historically attested cannibalistic stage of civilization, creating a homology between ontogeny and cultural phylogeny. Eliade approaches the subject from the opposite direction: cannibalism as a religiously instituted act of cosmic responsibility, through which the vegetative cycle is maintained and human beings participate in sacred causality. Burkert locates ritual cannibalism within the anthropology of sacrifice, werewolf mythology, and the Lykaia, tracing its structural role at the boundary between human and animal, community and transgression. Campbell documents its archaeological presence in Neanderthal skull-opening rites and its continued symbolic resonance in mythologies of fertility and initiation. Across these positions, cannibalism functions not as mere primitivity but as a charged symbolic operator that marks the place where nourishment, aggression, incorporation, and the sacred converge — a site where depth psychology and comparative religion discover their most uncomfortable common ground.
