Freud very quickly complemented his psychobiology with a sociobiological theory of culture and society. As early as 1897, he rooted the psychological phenomenon of repression (shame, disgust) in what he called a “primary,” “organic” repression that corresponded in the history of the species to the adoption of the erect stature and the abandonment of the oral-anal-urethral zones as sources of sexual excitement. To this biological origin of the civilizing process, Freud added in Totem and Taboo the murder and cannibalistic incorporation of the “primal father,” an event supposed to account at the collective, phylogenetic level for the prohibition of incest, and at the individual, ontogenetic level for the “decline” of the Oedipus complex during the latency phase of the libido and the corresponding emergence of an internal “superego.” The whole development of culture is thus viewed by Freud as a constant recapitulation and commemoration of this guilt-producing event whose unconscious memory is imprinted in the “archaic heritage” of the human race and transmitted compulsively through the generations, in conformity with Lamarck’s theory of inheritance of acquired characteristics.
