Ever since the discovery of Marx's Early Writings, most of the literature concerned with Marx's intellectual development has centred around the so-called gap between the 'young' Marx, who was considered to be a humanist thinker, and the 'older' Marx, who was held to be a determinist with little concern for anything outside his narrow theory of historical materialism. Dr Avineri claims that such a gap between the 'young' and 'older' Marx did not exist. He supports his claim by a detailed study of the whole corpus of Marx's writing on social and political thought.
