It is about the genealogical ilation that goes from Freud's candid anthropological concerns to the reading that Lévi-Strauss made of his total work, his impression and points of influence, until the creation of the anthropological structuralism, which he puts at the tip of his center I spin the unconscious not as a dark hell of sinister passions, but as a symbolic network of connection of moles and prohibitions, of gaps and ruptures that establish legitimacies, squares, oppositions and conjunctions of forces among men.
