"Until now the history of knowledge has largely been about formal and documented accumulation, concentrating on systems, collections, academies, and institutions. The central narrative has been one of advancement, refinement, and expansion. Martin Mulsow tells a different story. Knowledge can be lost: manuscripts are burned, oral learning dies with its bearers, new ideas are suppressed by censors. Knowledge Lost is a history of efforts, from the Renaissance to the Enlightenment, to counter such loss. It describes how critics of ruling political and religious regimes developed tactics to preserve their views; how they buried their ideas in footnotes and allusions; how they circulated their tracts and treatises in handwritten copies; and how they commissioned younger scholars to spread their writings after death." --
