ABSTRACT
Throughout Freud's work, he sought to highlight the specific mechanisms of psychosis and to establish the differences between neurosis and psychosis. Freud was also concerned to study the particular language of the schizophrenic. According to Freud the disavowal of reality is the specific mode of psychosis. This mechanism consists in refusing unconsciously to see a reality that is unbearable and traumatising for the ego. Freud notes this splitting first in pathological mourning, where the ego of the depressive is "split" between a part that recognises the loss of the loved object or ideal and a part that denies it. In neurosis, the preconscious system intervenes in the process of repression. In "The Unconscious", Freud shows that the unconscious reveals itself better in a psychotic patient than in neurosis, owing to the absence of the obstacle created by repression.
