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.

To emphasize the importance of beauty is to connect art again to emotion and desire. To find something or someone beautiful is not simply to appreciate what you now see or know about them. It also involves the desire to get to know them better, in the hope that what you will discover will, in some way that you can't know at the time, make your life better, just as your relationship with it so far has also made it better.

To find something beautiful is to hope that your life will be better if that is a part of it. Unfortunately, the promise of a better life that beauty makes and the hope that it will be fulfilled are not always realized: beauty, like friendship, is also double-edged.

My own view is that friendship is essential to our becoming who we are. It provides a context within which we can, more or less safely, try different ways of being, different approaches to life, and our friends, to whom we open ourselves and by whom we are willing to be influenced and directed, play a central role in what becomes of us.

So long as we find anything beautiful, we feel that we have not yet exhausted what [life] has to offer […] That forward-looking element is … inseparable from the judgment of beauty.

In contrast to the values of morality, which depend on and encourage our similarities to each other, values like friendship or beauty depend on and encourage our differences. Ultimately, friendship is essential to our fashioning ourselves in ways that don't simply repeat the fashions of our surroundings: it is a mechanism of individuality.

It is clear that friendship is by and large crucial to human life. And I believe, in contrast with most of the philosophical tradition deriving from Aristotle, that it is not limited to a very few perfect individuals.
