At the height of the Algerian War, Sartre embarked on a fundamental reappraisal of his own philosophical and political thought. The result was the Critique Of Dialectical Reason, an intellectual masterpiece of the 20th century, now republished in a new edition with a major original introduction by Fredric Jameson. In it, Sartre set out the basic categories for the renovated theory of history that he believed was necessary for post-war Marxism. Sartre's formal aim was to establish the dialectical intelligibility of history itself, as what he called "a tantalization without a totalizer." But, at the same time, his substantive concerns were the structure of class struggle and the fate of mass movements of popular revolt, from the French Revolution at the end of the 18th century to the Russian and Chinese revolutions in the 20th: their ascent, stabilization, petrification, and deviance, in a world still overwhelmingly dominated by scarcity.
