Philosophy is all about being, knowing, and acting. It poses daring questions such as what exists, what counts as knowledge, and how do we know things? And, as life becomes more and more complicated, people turn to philosophy to help themselves better understand the world around them-politics, religion, family, the environment, and more. The Complete Idiot's Guide to Philosophy, Second Edition will continue the first edition's success in exposing beginners to the world of philosophy, its ideas, and its philosophers. It will contain expanded content on existing ideas and philosophers covered in the first edition, but it will also introduce new philosophers whose ideas were not included in the first edition, but whose contributions to the world of philosophy are perhaps now less obscure.
