Establishing a rigorous program of symptomatic reading that cuts through the silences and lacunae of Capital to reveal its philosophical core, Louis Althusser interprets Marx's structural analysis of production as a revolutionary break-the basis of a completely new science. Building on a series of Althussers's conceptual innovations that includes overdetermination and social formation, Etienne Balibar explores the historical and structural facets of production as Marx understood them, scrutinizing many of the most fundamental points in Capital, as though for the first time.
