In Keywords (1976), Raymond Williams devised a "vocabulary" of culture and society that reflected the vast social transformations marking the post-war period. Although these transformations could not be perceived directly or all at once, Williams revealed how they could be grasped by investigating changes in word usage and meaning. Following Williams, we ask: what vocabulary might illuminate the social transformations marking our own contested present? How do these words shape the political imaginary of todays radical left?Bringing together the insights of dozens of scholars and committed troublemakers, Keywords for Radicals constellates a vocabulary of contested words that shape todays political landscape. Beginning from a consideration of the current radical context, each entry highlights a terms contested variations, traces the evolution of its usage, and speculates about the radical implications of particular term-use trajectories. More than a glossary, Keywords for Radicals makes clear that contests over word usage and meaning are themselves meaningful. By forcing words to reveal the underlying social contradictions they symptomatically express, the contributors to this volume provide an important new vantage on the terrain—and the stakes—of contemporary struggle.
