Most people think about philosophical problems without realizing it: What really exists? Can we know anything? Is anything really right or wrong? Does life have any meaning? Is death the end of everything? These problems have been written about for thousands of years but the philosophical raw material comes directly from the world & our relation to it. In this remarkable book distinguished philosopher Thomas Nagel leads the reader into the heart of nine of these central problems of philosophy. In vivid accessible prose he brings the issues to life demonstrating why they have continued to baffle & fascinate countless thinkers across the centuries. What Does It All Mean?" challenges us to think hard & think clearly; to ask questions to argue to try out ideas & raise possible objections to them in a word to become philosophers ourselves."
