The conceptof desire is central to Lacan’s theory and practice, even if it is not among the four fundamental concepts of psychoanalysis—unconscious, Trieb, repetition, transference, it can be understood that it underlies all of them. The concept of desire is inherent to the ethics of psychoanalysis that Lacan formulated, therefore it is especially concerned with a practice whose operation is defined by the function of analyst’s desire. However, this central thesis of Lacan has been called into question with regard to psychosis. Some Lacanian scholars have derived from the foreclosure of the Name-of-the-Father a lack of desire in psychosis.
This paper aims to discuss the relative absence of references to the concept of psychotic desire in Lacanian schools. The debate is relevant because Lacan did exclude neither desire nor psychosis from his conception of analytic treatment.
