This innovative book hones in on key elements of Marx’s vast oeuvre, focusing on his contribution to social theory. Themes addressed include: the declining utility of Hegelian philosophy for Marx, his deepening confrontation with Ricardian political economy, Engels’ distorting impact on the publication of Capital, the place of the accumulation of capital, and especially of ‘primitive accumulation’, in Marx’s thought, and more. Extending beyond an analysis of the writing of Marx himself, Zarembka highlights the contributions of Rosa Luxemburg in the realms of political economy and nationalism and closes the book with a consideration of state conspiracies.
