"In Descartes's Meditations, one of the key texts of Western philosophy, the thinker rejects all his former beliefs in the quest for new certainties. Discovering his own existence as a thinking entity in the very exercise of doubt, he goes on to prove the existence of God, who guarantees his clear and distinct ideas as a means of access to the truth. He develops new conceptions of body and mind, capable of serving as foundations for the new science of nature. Subsequent philosophy has grappled with Descartes's legacy, questioning many of its conclusions and even his basic approach, but his arguments set the agenda for many of the greatest philosophical thinkers, and their fascination endures." "This new translation includes the Third and Fourth Objections and Replies in full, and a selection from the rest of these exchanges with Descartes's contemporaries that helped to expound his philosophy."--BOOK JACKET.Moriarty, Michael is the author of 'Meditations on First Philosophy', published 2008 under ISBN 9780192806963 and ISBN 0192806963.
