For those interested in the history of Philosophy, beginning with our friends the ancients, I'd like to recommend a book on Philosophy called "Sophies World" by Jostein Gaarder.
As the blurb on the back says Jostein Gaarder accomplishes the amazing feat of jamming 3000 years of Philosophy into 400 pages. To me though the real achievement is the simplicity and clarity with which he introduces and explains the main ideas. Its very readable and you get a real sense of wonder at the development of human thought. I couldn't put it down! Hope some of you enjoy it too.
