Foucault and Lacan: the subject, the knowledge and the truth

The paper focuses the articulation point between Michel Foucault and Jacques Lacan thoughts. This point is directly linked to a research undertaken by both of them: the relation between the subject and the knowledge and truth. Their research is represented by Foucault lectures The Hermeneutics of the Subject and his book The Will to Know and by the teaching of Jacques Lacan. The authors sustain that Foucault's critics to psychoanalysis loose their effects when related to Lacan's teaching. The study aims to demonstrate that at the publication of the first volume of The History of Sexuality, Lacan had already overcome the problems indicated by Foucault: the relation between the psychoanalysis and the alliance device sustained by the law of desire and the truth remission to Edipo's mith.
