Logic: A Very Short IntroductionLogic is often perceived as having little to do with the rest of philosophy, and even less to do with real life. In this lively and accessible introduction, Graham Priest shows how wrong this conception is. He explores the philosophical roots of the subject, explaining how modern formal logic deals with issues ranging from the existence of God and the reality of time to paradoxes of probability and decision theory. Along the way, the basics of formal logic are explained in simple, nontechnical terms, showing that logic is a powerful and exciting part of modern philosophy.

The constant sideswipes at arguments for the existence of God were rather irritating, even when they were moreorless wellaimed sideswipes. The author seems to have a bit of a chip on his shoulder about the subject. Read full review
