Book excerpt: Marx and Critical Theory examines Marx’s main philosophical, political and social theoretical ideas. Its purpose is twofold: making sense of the concepts and theses of Marx, and showing that they remain relevant for contemporary critical theory. Part One focuses on Marx’s conception of philosophy. Part Two analyses the Marxian primacy of the practical. Part Three is devoted to Capital and the critique of political economy. This book will be useful for those who want to deepen their understanding of Marx’s main ideas, as well as for those who want to clarify what is at stake in contemporary debates about the ways in which contemporary critical theory could or should refer to Marx.
