The way the drive (Trieb) is lived by the subject in a singular manner identifies the different clinical structures: neurosis, psychosis and perversion. The perverse in his act is determined by the categorical imperative “jouissance”: he/she lives for the jouissance; he/she struggles to take its possession, to organize it and to prolong it (to extend it). Desire, in the perversion, does not emerge as a question about the desire of the Other, as it does in neurosis. It makes its presence as a hard and inflexible response under the form of will of jouissance” What about the real of jouissance in psychoanalysis? How would the analyst listen to the perverse?
