‘The Abolition of Prison’ provides a reflection from a longtime prison abolitionist on the ideas, actions, and writings of anti-prison activism over the last fifty years. This book powerfully makes the case for the end of prisons, punishment, and guilt and, instead, suggests we work towards social change, care, collectivity, and ending regimes of repression and violence. The book weaves together Lesage de La Haye’s own experience in prison, as a psychologist, and as an abolitionist, with arguments and proposals from abolitionist writings, and countless examples of prisoner actions, prison alternatives, and attempts to create a more just world. Lesage de La Haye argues simply that, if we take the justifications for prison and punishment at their word, we must evaluate the system as a complete failure and stop supporting and funneling money into it. There is a long history of alternative ways to address problems in society, both inside the Western systems of law and from Indigenous communities. Lesage de la Haye starkly portrays the effects of punishment, concluding that prison is simply a slow death. The move toward abolition is achievable today and necessary for a society free from systematized oppression.
