Book excerpt: Responses to Marx's Capital: From Rudolf Hilferding to Isaak Illich Rubin is a collection of primary sources dealing with the reception of the economic works of Karl Marx from the First to the Third International. The documents, translated for the first time from German and Russian, range from the original reviews of the three volumes of Capital and the three volumes of Theories of Surplus Value to the debates between the Marxist economists and the bourgeois academic representatives of the theory of marginal utility and the German historical school. The volume closes with six essays by the prominent economist Isaak I. Rubin, including ‘Essays on Marx's Theory of Money’ and ‘The Dialectical Development of Categories in Marx’s Economic System’.
