The current moment in psychoanalytic thinking has made a “turn towards the social,” but what does this mean in theoretical and practical terms. This presentation aims to provide a conceptual basis for the Social Unconscious as a register grounded in groups, and operating as a different kind of psychic life than what we are used to when we think of the personal unconscious. If we take the concept of the Social Unconscious seriously, this implies a fundamental change in our theoretical frameworks. And has implications for opening up the terrain of psychoanalytic practice, including the recovery and validation of the history of community psychoanalysis and new elaborations of training and practice.
