The now legendary Dialectics of Liberation congress, held in London in 1967, was a unique expression of the politics of dissent. Existential psychiatrists, Marxist intellectuals, anarchists, and political leaders met to discuss key social issues. Edited by David Cooper, The Dialectics of Liberation compiles interventions from congress contributors Stokely Carmichael, Herbert Marcuse, R. D. Laing, Paul Sweezy, and others, to explore the roots of social violence. Against a backdrop of rising student frustration, racism, class inequality, and environmental degradation-a setting familiar to readers today-the conference aimed to create genuine revolutionary momentum by fusing ideology and action on the levels of the individual and of mass society. The Dialectics of Liberation captures the rise of a forceful style of political activity that came to characterize the following years.

One of the fruits of the revival of socialist economic theory over the past decade has been a wide-ranging debate about the validity of Marx's labour theory of value. At the heart of the discussion stands the theoretical work of Piero Sraffa and the conclusions drawn from it by such economists as Ian Steedman. Initially confined to a relatively narrow circle of specialists, the controversy about value theory has since spread to wider circles of the left. But although general awareness that the stakes of the dispute are of concern to all socialists is now extensive, understanding of the issues involved has remained more restricted than need be. This volume presents, for the first time, a comprehensive yet accessible overview of the discussion. The essays discuss not only the value debate itself, but also its relevance to such issues as capitalist crisis, the theory of exploitation, and historical materialism. Comprehensible to the non-specialist, but without sacrificing rigour or oversimplifying the issues, the articles assembled here offer a definitive summary of the current state of one of the crucial aspects of Marxist thought.

The debate on the transition from feudalism to capitalism, originally published in Science and Society in the early 1950s, is one of the most famous episodes in the development of Marxist historiography since the war. It ranged such distinguished contributors as Maurice Dobb, Paul Sweezy, Kohachiro Takahshi and Christopher Hill against each other in a common, critical discussion. Verso has now published the complete texts of the original debate, to which subsequent discussion has returned again and again, together with significant new materials produced by historians since then. These include articles on the same themes by such French and Italian historians as Georges Lefebvre and Giuliano Procacci. What was the role of trade in the Dark Ages? How did feudal rents evolve during the Middle Ages? Where should the economic origins of mediaeval towns be sought? Why did serfdom eventually disappear in Western Europe? What was the exact relationship between city and countryside in the transition from feudalism to capitalism? How should the importance of overseas expansion be assessed for the 'primitive accumulation of capital' in Europe? When should the first bourgeois revolutions be dated, and which social classes participated in them? All these, and many other vital questions for every student of mediaeval and modern history, are widely and freely explored. Finally, for this Verso edition, Rodney Hilton, author of Bond Men Made Free, has written a special introductory essay, reconsidering and summarising relevant scholarship in the two decades since the publication of the original discussion. The result is a book that will be essential for history courses, and fascinating for the general reader.
