This is a major, wide-ranging, and comprehensive book. A philosophical investigation that is also a literary and historical study, Truth and Truthfulness asks how and why we have come to think of accuracy, sincerity, and authenticity as virtues. Bernard Williams' account of their emergence is as detailed and imaginative as his defense of their importance is spirited and provocative. Williams asks hard questions, and gives them straightforward and controversial answers. His book does not simply describe and advocate these virtues of truthfulness; it manifests them.
