This class initiates a reading of Marx's classic critique of political economy, Capital, along with a selection of the principal philosophical readings of the mature Marx since the 1960s: Louis Althusser's Reading Capital, Michel Henry's Marx, and Moishe Postone's Time, Labor, and Social Domination. Emphasis is placed upon developing a categorial understanding of Marx's conceptual apparatus adequate to the contemporary context, in the wake of the collapse of actually-existing Socialism, industrialization, and the crisis of valorization in the Twenty-First century.
