This book seeks to answer why it is so difficult for us to imagine a society in which prisons are not such a predominant element of the geographical and social landscape? How do we imagine and fight for a world that does not engender forms of terror, that does not engender wars, that does not need enemies to sustain itself? We need to reconfigure again and again the terms and territoriality of our disputes. The text argues that we need new theories, new practices, and new political communities, to reimagine the relationship between incarcerated people and their allies outside, to abandon the notion that capitalism is inevitable. We still need to confront the mediatized crime that makes us transfer to crime a lot of fears for which we have no way of expressing ourselves and create a new abolitionist movement that dismantles the structures of incarceration, that invents alternative care institutions, that imagines a livable life for all.
