Psychic representability and psychosis

Abstract

This paper first deals with Lacan's return to Freud as a spectral return to Freud, crossing psychoanalytic praxis and philosophy, marking their points of distinction precisely in the place called truth. This is also accompanied by the radical questioning of the subject in philosophy. On this, psychoanalysis questions philosophy about its desire and yielding on this at the moment when its systematic tendency covers something that manifests itself in the place of the Cartesian cogito. Next, in this fault site of Cartesian Spaltung, the article situates the Lacanian invention of the object a and proposes, from a philosophical perspective, to think about a shift from object a to constitution. To do so is to see how it is precisely the function of the phantom that links the subject of the unconscious to the object a that establishes categorical fixations and, in general, scientific discourses.
