This book is absolutely fantastic. It's structured very well and uses basic and familiar examples to demonstrate (for many) foreign concepts. The man himself is a bit a gem too; having had the great fortune to have studied under him in a handful of University papers I'd say that I have a small man-crush.
This book and the accompanying course made me feel like a child again in the sense that it refreshed a sense of wonderment and awe towards the external world. Well worth reading as an introduction to Philosophy.
