What does it mean to be truthful? What role does truth play in our lives? No philosopher is better suited to answer these questions than Bernard Williams Writing with his characteristic combination of passion and elegant simplicity, he explores the value of truth and finds it to be both less and more than we might imagine. This book presents a powerful challenge to the fashionable belief that truth has no value, but equally to the traditional faith that its value guarantees itself. Bernard Williams shows us that when we lose a sense of the value of truth, we lose much both politically and personally, and may well lose everything.
