Intense debates in recent decades have provoked major new directions in Marxist theory. Earlier reductionist notions of knowledge, dialectics, contradiction, class, and capitalism have been challenged and profoundly transformed. Economic determinism has given way to new kinds of philosophic, social, and economic analysis such as the one Resnick and Wolff here develop around overdeterminism. Showing that Lenin, Lukacs, Gramsci, Mao, and Althusser contributed concepts of knowledge, class, and society that can radically alter traditional dialectical materialism, the authors demonstrate how this alteration also transforms Marxist economic theory. The dramatic result is a new Marxian theory, a new analysis of class, enterprise, and state.
