Abstract
JEAN-PAUL SARTRE in the Critique de la raison dialectique, develops a theory of praxis which extends the anthropology of L'être et le néant while simultaneously claiming to correct and complete Marxism. Central to Sartre’s argument are two assertions: that dialectic is fundamental to human action, and that all historical development is rooted in the praxis of individual persons. These twin assertions, by insisting upon the existential element in social change, do not merely correct Marxism. They fundamentally alter it. In affirming the dialectical structure of praxis, Sartrean Marxism is compelled to deny a dialectic of history. It modifies the Marxian dialectic by radically constricting its scope, denying a becoming of the dialectic by insisting upon a dialectic of becoming.
