The motif of the postwar era is found in the name itself—post. The 1950s sought to be post-ideological. The 1960s launched post-bourgeois culture, one that sets aside nettlesome constraints. Intellectuals throughout the West adopted postmodernism, an outlook that eases the demands of truth. Before 1989, progressives in the West were already post-Marxist. That meant shifting away from Marx’s rigorous dialectics toward open-ended campaigns for “liberation” that pose no threats to capitalism.
