The fundamental myth invented by Freudian psychoanalysis on the origin of culture starts from a primordial act of violence: the entire human family owes its origin to a founding crime. Diverging from the entire dominant to western philosophical tradition, Freud postulates a state of nature at war or in a primordial anarchy in which man is a wolf for man. Far from giving up this state of unsociable sociability, humans make a pact of coexistence that regulates a foundational violence through another institutionalized violence, incapable of proscribing this indestructible facet of human nature that shall always continue. This paper attempts to reconstruct this psychoanalytic model of cultural analysis developing the consequences of this ambivalence of the human drives with regard to the law. The main purpose of this essay is to demonstrate that cultures that do not assume the basic prohibitions of civilization -those of incest and parricide- are bound to repeat them.
