What future is there for the left, faced with the challenges of the twenty-first century? Based on a lifetime's experience in politics, Marta Harnecker addresses the crisis facing the left today. At its heart, this book is a critique of social democratic realpolitik. Harnecker reminds us that, contrary to today's orthodoxy, politics is not the art of the possible but the art of making the impossible possible by building a social and political force capable of changing reality. She believes that the social experiments being carried out in Latin America today hold out hope that an alternative to capitalism is possible; they are essentially socialist, democratic projects in which the people are the driving force. To create a real alternative to capitalism, though, the left must change. Rebuilding the Left offers real hope to those who still believe that we can create a different world.
