This volume brings together works written by international theorists since the fall of the Berlin Wall, showing how today's crisis-ridden global capitalism is making Marxist theory more relevant and necessary than ever. This collection of key texts by prominent and lesser-known thinkers from Latin America, Asia, Africa, America, and Europe showcases an area of scholarly analysis whose impact on academic and popular discourses as well as political action will only grow in the coming years. It reflects today's sense of planetary eco-emergency and a heightened interest in political economy that follows discontentment with the growing inequalities in the West and the unequal nature of development in the global South. The work is organized thematically, with sections covering the present historical conjuncture, the contemporary shapes of the social, philosophical concepts, theories of culture, and the status of the political today. This new formulation of the unity and nature of contemporary Marxist theory will be an invaluable resource to any humanities and social science student learning about social and political thought and theory.
