Freud was conflicted in relation to his religious background. On the one hand, he was very clear on his adherence to a scientific Weltanschauung. On the other, he was fascinated by the Moses figure and one may see a Judaist structure in his way of thinking. The aim of this paper is to reflect on this conflict and the question of faith in psychoanalysis. After looking at object and method in religion and psychoanalysis, the authors go into the concept of ‘psychic reality’ and its change in the history of psychoanalysis. Through an analysis of Freud’s A Disturbance of Memory on the Acropolis and the function of literature, it is claimed that faith may be seen as a condition for the sense of experiential reality.
