This book presents a new assessment by Immanuel Wallerstein titled The Global Left: Yesterday, Today, Tomorrow with additional chapters by prominent social theorists. Global Left is a different concept from globalization and speaks to the appropriateness of the unit of analysis of global change and its implications both for intellectual understanding and political action. Wallerstein considers anti-systemic movements, dilemmas of the left in relation to the structural crisis of the modern world-system, and tactics and strategies for political action. The book includes new essays by Etienne Balibar, John K. Galbraith, Johan Galtung, Nilufer Gole, and Pablo Gonzalez Casanova in conversation with Wallerstein's core ideas.
