Psychoanalysis is a survivor of the Holocaust. It was founded and flourished in central European centers that would be destroyed by the Nazis. A core group of refugees who lived through persecution and exile were instrumental in rebuilding their movement on alien shores. They had no opportunity to mourn the loss of their culture or their leader, Freud, whose death was overshadowed by the cataclysmic upheaval around them. Though its trauma has been dissociated, it is represented in psychoanalytic ideas and enacted in institutions within the context of delayed or incomplete mourning. For example, authoritarianism in psychoanalytic institutions will be explored as a reliving of the trauma of both fascism and exile, and not merely typical group psychology. Further evidence of the impact of dissociated trauma includes the astonishing scotoma for actual events in treatment of Holocaust survivors; the extreme privileging of infantile fantasy over reality, and attention to childhood neurosis at the expense of adult catastrophic events.
