Since the onset of the Global Financial Crisis the ideas of Karl Marx have once again become prominent in social and political thought. This book turns to Marx’s theory of revolutionary subjectivity to assess the work of three contemporary global theorists: Ernesto Laclau, Antonio Negri, and Alain Badiou. While providing a critical examination of the theory of revolutionary subjectivity in Laclau, Negri and Badiou, due to the fact such aspects were already present in Marx’s own theory, this book also offers insights into the nature of post-Marxism itself. Whilst accepting their respective differences, the conclusion offers a synthesis of all three theoretical approaches to understand the constitution of revolutionary subjectivity today.
