ABSTRACT
Based on the constitutive ambiguity of the One that Lacan promotes from logic and mathematics in the seminaries O saber do psicanalista e ...ou pior, between 1971 and 1972, the article seeks to support the theory of sexuation developed in that period and clarify that such conceptualization resumes the Freudian subversion of the drive polymorphism. If the drive does not have any instinctual determination as to its object, it appears that this same misunderstanding is revealed as the impossibility of proportion and sexual relationship [rapport sexuel] for the speaking being, who grammatically positions themselves in the structure of language from this impasse. Thus, the bifidity of the One, between set and element, sameness and difference, particularity and universality, ex-sistence and relativity, real and symbolic, rewrites the (sexual) difference according to psychoanalysis. Sex, therefore, is the very absence of any reference other than the constitutive opacity of the signifier, it is the fundamental evasion of the being from the truth.
