In this article we retrace the route in regard to the Freudian concept of paranoia in his work. This route will be considered from the pre-psychoanalytical texts, through which is considered the greatest of Freud's text psychosis (Case Schereber), and culminating in his analysis that take into account his second theory of the psychic functioning and the conflict drives. Our goal is to demonstrate how Freud, in his elaboration of the issues related to psychosis, and paranoia, more specifically, never avoids to face the challenges imposed by the clinic. And for not setting back to these challenges is that his theory will be formulated in a dialectical relationship between the dilemmas of practice and the need to establish a theoretical rigor. This theoretical rigor allows the establishment of a differential diagnosis between neurosis and psychosis as well as lays the groundwork so that post-freudian psychoanalysts could think of a direction for the treatment of psychosis.
