This is an account of the Brazilian collective Margens Clínicas (Clinical Margins), committed to thinking about the interfaces between psychological suffering and the pathologies of social structure, and working to create clinical/psychoanalytic methods aiming at repairing the damage done by state violence. The author discusses the Brazilian colonial-slavery matrix and its psychic and social forms. He further elaborates on a clinical ‘device’ called aquilombamento nas margens, which aims at a psychosocial intervention and addresses the intersection between race relations and mental health.
