Sophie's World is a fantastic book about philosophy through the ages. The storyline moves at a fast enough pace for those who find the lessons a little hard to get through and the philosophy is explained in a concise and very readable manner. For those interested in philosophy, the book is a wonderful refresher of the highlights of western philosophy. For those new to it, the book is a wonderful way to be introduced to philosophy and the core ideas of some of the discipline's greatest thinkers. I can't say enough good things about this book. Let yourself enter Sophie's World!
