"A landmark in modern social thought… A turning point in the thinking of our time."—Raymond WilliamsAt the height of the Algerian war, Jean-Paul Sartre embarked on a fundamental reappraisal of his philosophical and political thought. The result was the Critique of Dialectical Reason, an intellectual masterpiece of the twentieth century, now republished in two volumes with major original introductions by Fredric Jameson.Here, Sartre began a new theory of history that he believed was necessary for postwar Marxism. His substantive concern was the structure of class struggle and the fate of mass movements of popular revolt, from the French Revolution at the end of the eighteenth century to the Russian and Chinese revolutions in the twentieth.
