Book excerpt: Do you think that philosophy is an activity for old men in sandals with long white beards? Or people who sit under trees and wait to be struck on the head by apples? If so, then you owe it to yourself to explore the insights of this book. In conversational yet artful prose, James H. Hall reveals the many ways that you can actually enjoy and use philosophy in the course of your everyday experience. Rather than presenting philosophy as an endless list of ancient truths revealed by geniuses, or as instant wisdom, Hall presents philosophy as a concrete, practical enterprise that, once you've seen how it works, you can continue on your own.
