Freud, Lacan, Derrida : psicanálise em différance

Abstract

In creating psychoanalysis, at the end of the 19th century, Freud dedicated himself to explain the epistemological foundations in which he grounds his assumption of having created a new science, a new branch of natural sciences, with which it shared these epistemological foundations as well as its Weltanschauung. In mid-twentieth century, originating at the critique of psychoanalytical scientificity that came especially from neopositivist epistemology, it fell to Jacques Lacan to resume the question of psychoanalytical epistemology and to consolidate it over new foundations. The present thesis seeks to highlight the fact that, after the lacanian approach to the issue, an original way of conceiving psychoanalysis comes from outside of the psychoanalytical field, more precisely from Jacques Derrida’s philosophy. According to Derrida, psychoanalysis not only doesn’t fit in its entirety within the limits of a regional science, but it also comes to constitute, in harmony with derridean graphemathics, an original way of viewing the constitution of reality in general. The thesis follows the path of derridian critique to freudian epistemology and to lacanian structuralist psychoanalysis of the 1950’s, regarding the contemporary thought that seeks, in the last Lacan through the psychoanalytical field, and in Alain Badiou through the field of philosophy, the foundations of both in the fields of mathematical formalisation. Other than allowing to conceive a new psychoanalytical epistemology consolidated in his philosophy, the thesis follows Derrida in pointing at the challenging paths of a psychoanalysis to come.
