I'm more than a bit surprised that this book has not received any reviews yet. Although it may not be suitable for a general audience due to its use of philosophical terms of art, the arguments given can be followed without too much difficulty by any educated layperson. If you're an agnostic/atheist/secular humanist/skeptic (i.e., you don't believe in ghosts, goblins, or gods), you'll find in this book the philosophical reasoning behind what many people would probably call the "materialist" position, but philosophers call "physicalism." The author argues for a particular type of physicalism called "realization physicalism," which he shows can be framed as a scientific hypothesis. He then goes on to demonstrate how realization physicalism does a better job explaining the world as we know it than any competing viewpoint (such as dualism). If you've read books by Dawkins, Hitchens, Shermer, Martin, Stenger and so on, consider moving up to something more challenging, but ultimately more rewarding.
