Foucault is one of the most brilliant philosophers of the 20th century. Freud is the creator of psychoanalysis. The former's importance in the latter's work is so great that Allouch once declared: "Psychoanalysis will be Foucaultian or it will not exist." In these pages, Julio Ortega Bobadilla, psychoanalyst and philosopher from Poitiers, links it with Freud's work in a very enjoyable text that retains its rigor.
