This book traces the historical postcolonial journey of four generations of Jamaican psychiatrists challenging the European colonial ‘civilizing mission’ of psychiatric care. It details the process of deinstitutionizing patients with chronic mental illness using psychohistoriographic cultural therapy, by engaging them in creating sociodrama and poetry writing, not only to express and reverse the stigma contributing to their marginalized status, but also to reconnect them to a centuries-long history of oppression. The author thereby demonstrates that psychological decolonization requires a seminal understanding of the complex mental inter-relationship between slaves and slaveowners. Further, it is shown how the model analyzes the antipodal dialectic history of descendants of Africans enslaved in the New World by brutish British Imperialists suffering from the European psychosis of white supremacy.
