Abstract EN:

The commentary on aristote's work that lacan gave in the course of his seminary -that is to say thirty years- is nowadays widely unrecognized. We have been wishful of demonstrating the richness and the importance of this commentary for the modern interpretation of stagirites. The title of this thesis reflects how interested lacan could be in the philosopher's thought. The object of our work has first been to explain why the ethics to nicomaque and politics which are indissociable, were according to him the paradigm of the classical reflexion on the subject. It has also been to show what inferences he drew from all that in his own discipline. Then we have decided to stress on the link between this masterful ethics and the question of being that he brought up. Heidegger's philosophy as well as that of the anglo-saxon essentialists revived aristote's work, each in their own way : what interpretation did lacan put forward them, which was to give a clinic significance to hupokeimenon and to the singular ousia? the last purpose of our study has been to show that lacan built up his logic on the foundations of aristote's. He had recognized on him the advised precursor of the science of real, the one of whom he wanted to be the successor. He had also recognized the inventor of the modal reasoning of which he introduced the application into clinics.
