Can the Marxist tradition still provide new resources for thinking 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 Sieyès 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. Privileging not the single time of historical development, but the plural temporalities that intertwine in and constitute any given historical conjuncture, and arguing against merely subjectivist theories of temporal multiplicity, this volume studies the articulation of the real, plural temporalities of mass political action. Comprehending their dynamics is a necessary precondition for a renewed politics of emancipation.
