A Beginner's Guide to Reality is an introduction to philosophy for people who don't read philosophy. Jim Baggott's sources range from Aristotle to The Matrix. He examines the major developments in Western philosophical thought on the nature of reality, at each of three levels - social, perceptual and physical. (Do money, colour, or photons exist?) The book systematically investigates these levels, peeling away the assumptions we make about those parts of reality that we take for granted.
