Can the Marxist tradition still provide new resources for understanding the specificity of historical time? This volume proposes to transform our understanding of Marxism by reconnecting with the 'subterranean currents' of plural temporalities that have traversed its development. From Rousseau and Sieyes to Marx, from Bloch to Althusser, from Gramsci to Pasolini and postcolonialism, the chapters in this volume seek both to valorise neglected resources from Marxism's contradictory history, and also to read against the grain its orthodox and heterodox currents.
