Most, if not all, other books on naturalism are written for professional philosophers alone. Stewart Goetz and Charles Taliaferro offer a book that — without losing anything in the way of scholarly standards — is primarily aimed at a college-educated audience interested in learning about this pervasive worldview. Naturalism groups the various terms of this philosophy into two general categories: strict naturalism and broad naturalism. According to the strict version, all that exists can be exhaustively described and explained by the natural sciences. As Goetz and Taliaferro explain it, broad naturalism allows that there may be some things beyond physics and the natural sciences, but insists that there can be no reality beyond nature — i.e., God — and explicitly rules out the possibility of souls. The authors argue that both categories face substantial objections in their failure to allow for consciousness, human free will, and values. They offer sustained replies to the naturalist critique of the soul and the existence of God and engage in critical evaluations of works by scholarly and popular advocates of naturalism — Daniel Dennett, Richard Dawkins, Thomas Nagel, Jaegwon Kim, and others.
