This year marks the 150th anniversary of Marx’s Capital and the centenary of the Russian Revolution. Both anniversaries raise vital questions for Marxist theory and practice today. How can value theory inform an analysis of modern capitalism? What can we learn from history and how do we understand theory and politics in the changed conditions of the 21st century in Australia and around the world? What do contemporary debates around social reproduction mean for the Marxist tradition? And how should Marxist theory and practice inform an understanding of and resistance to today’s ecological crisis?
