||It is a decent introduction to popular philosophical problems. Covers everything from problems of consciousness (The measure of a man) to problems with personal identity (tuvix, the transporter). This is the bread and butter of philosophical metaphysics and makes for a good introduction to anyone that ever stopped to think about whether you, the person reading this review, actually continues to exist in any meaningful way when you're taken apart at the molecular level and re-assembled. Why 3-stars? Sometimes the level of analysis isn't as rigorous as I would have liked and many views (which readers may have found attractive) are described too briefly for my taste. I highly recommend this book.
