Book excerpt: This book is about the intrusive fear that we may not be what we appear to be, or worse, that we may be only what we appear to be and nothing more. It is concerned with the worry of being exposed as frauds in our profession, cads in our love lives, as less than virtuously motivated actors when we are being agreeable, charitable, or decent. Why do we so often mistrust the motives of our own deeds, thinking them fake, though the beneficiary of them gives us full credit? Much of this book deals with that self-tormenting self-consciousness. It is about roles and identity, discussing our engagement in the roles we play, our doubts about our identities amidst this flux of roles, and thus about anxieties of authenticity.
