This article seeks to place castration as the fundamental point of difference between Foucault and psychoanalysis. First, we will learn the Foucault's criticism to psychoanalysis in order to grasp the originality of the later. Secondly, the author seeks to show how castration leads psychoanalysis and Foucault to two fundamentally different positions of say-truth.
