Examines the history, the limits and the promise of the human mind -- and the knowledge of which it is capable. Examines the performance of that miracle of memory and creative power -- the human mind. From the intellectual and moral monuments of the Greeks, the Romans, the Judaeo-Christians and our contemporary thinkers, the author explores the meaning of our culture. Out of this book come the answers to some of the pressing questions of our time -- on freedom, on censorship and on our educational system. And out of it too comes a clear definition of knowledge and new insights into the strength and limitations of the mind.
