Martin Heidegger and Karl Marx remain two of the most influential thinkers in philosophy, in political science and other social sciences, and in the humanities. Yet there has never been a full-length study in English of the relationship between their ideas, and there has only been one study in German (from 1966). A Productive Dialogue fills this gap and contradicts the widely held assumption that Heidegger had no significant engagement with Marx. Hemming focuses on four related areas of inquiry-Heidegger's reading of Marx; Marx's relation to G. W. F. Hegel; Heidegger's disastrous political involvement with National Socialism; and the significance of Hegel, Marx, Heidegger, and Friedrich Nietzsche for the politics of the twentieth and twenty-first centuries. A Productive Dialogue explores the understanding of political processes, systems, and behaviour that animates both thinkers.
