Forty years after the defeat of Nazism, and twenty years after the great wave of decolonization, how is it that racism remains a growing phenomenon? What are the special characteristics of contemporary racism? How can it be related to class divisions and to the contradictions of the nation-state? And how far, in turn, does racism today compel us to rethink the relationship between class struggles and nationalism?<br>This book attempts to answer these fundamental questions through a remarkable dialogue between the French philosopher Etienne Balibar and the American historian and sociologist Immanuel Wallerstein. Each brings to the debate the fruits of over two decades of analytical work, greatly inspired, respectively, by Louis Althusser and Fernand Braudel. Both authors challenge the commonly held notion of racism as a continuation of, or throwback to, the xenophobias of past societies and communities. They analyze it instead as a social relation indissolubly tied to present social structures—the nation-state, the division of labor, and the division between core and periphery—which are themselves constantly being reconstructed. Despite their productive disagreements, Balibar and Wallerstein both emphasize the modernity of racism and the need to understand its relation to contemporary capitalism and class struggle. Above all, their dialogue reveals the forms of present and future social conflict, in a world where the crisis of the nation-state is accompanied by an alarming rise of nationalism and chauvinism.
