Nathan Coombs demonstrates that the Marxist science of history has been reimagined by a strand of contemporary French theory after Louis Althusser. Taking a comparative approach, he explores the technical details of both traditions’ historical sciences. He argues that their articulations of history and event affect how we approach political transformation and view the role of theoreticians in political practice. Coombs establishes the continuities and discontinuities between classical Marxism and Althusserian theory, bringing you new readings of Hegel, Marx, Lenin, Althusser, Badiou, Meillassoux and complexity theory.
