"I have learned quite a bit from Claude Lévi-Strauss," says Lacan. Initially, the symbolic structure dominates. What? The social, the kinship relations, the ideology, but also, for each individual, their relationship to the world, their sensory relationships, their familial complex. Subsequently, the imaginary scenarios, namely the myths and the rites that underpin them, are necessary to obscure the contradictions of economic and social reality. Third lesson: these formations transform; they do so according to laws that are mathematical. Lacan invests these lessons into psychoanalysis. In his struggle with a real that cannot be symbolized, the subject produces a phantasmatic scenario that stages a stylized behavior, which can take on the appearance of a true ceremony, indeed, it may be accompanied by a brief madness.
