In 1843 Marx was twenty-five years old. He had just married, apparently on the strength of the modest salary he was to receive for editing, jointly with Arnold Ruge, a periodical called the Deutsch-Französische Jahrbücher (Franco-German Annuals), the purpose of which was to promote the union of German philosophy with French social science. Only one double-number of this journal appeared in 1844. It contained Marx’s criticism of the Hegelian Philosophy of Right and his exposition of the social significance of the Jewish question, in the form of a review of two works by Bruno Bauer. Translations of both articles are given in this volume. They possess a special interest for the Marxian student, as they exhibit the grafting of a materialist philosophy upon the idealist philosophy of Hegel, and show the employment of the Hegelian dialectic in the investigation of political and historical questions. It was not long before Marx and Ruge became intellectually estranged, and the third essay, “The King of Prussia and Social Reform,” which appeared in the Paris socialist journal Vorwärts, contains a severe polemic against Ruge. In the same organ Marx published an elaborate defence of Engels in particular and communists in general from the strictures of Karl Heinzen, a radical republican politician. In both essays Marx ranges over a wide field, and develops his own views upon economic, political and historical questions
