This work intends to analyze the link between clinical and research in the field of psychoanalysis and its aftermath in reading the subject of the unconscious. Therefore we started at the realization that, in addition to clinical cases, Freud also used the study of artists and cultural productions. In particular, in studying psychosis, Freud's precursor contribution came from reading the published Memoirs of Schreber. It was by reading and analysing this book that the psychoanalyst based his main theses about paranoia. In this article, we highlight his proposition that delusion is an attempt to rebuild the world, shaken by the psychotic break. From this reading of Freud, we seek to examine how, in a similar way, the work of a mad genius, Arthur Bispo do Rosario, demonstrates the actuality of Freudian method and the importance of apprehending psychosis, specifically, this link with cultural production.
