In What Do We Really Know? Simon Blackburn addresses the twenty most-asked philosophical questions, including 'Can machines think?', 'What is the meaning of life?', 'Is death to be feared?', 'Why be good?', 'What am I?' and 'What do we really know?' Each 3000-word essay examines a question that has eternally perplexed enquiring minds, and provides answers from history's great thinkers.
