In this inquiry into Marx’s method of theorising, originally published in 1979, Roslyn Bologh analyses theory in the same way that Marx analyses the production of capital, and provides a set of rules for reproducing Marx’s method. The rules are developed through an examination of the Grundrisse, a text by Marx that combines his technical critique of political economy with his humanistic, philosophical concerns and his historical perspective. Dr Bologh concludes that Marx’s method, as dialectical phenomenology, offers a way of analysing language, knowledge and the social relations and practices of everyday life, as well as the more obvious phenomena of capitalism.
