Superb. --Chris Daly, Analysis Reviews This is an elegantly written and enormously stimulating book. It is full of original, provocative, philosophical argumentation. Maudlin shows by example what it is to do the best kind of naturalized metaphysics: one based on thorough acquaintance with real science, but unwilling to accept a superficial analysis of how it bears on deep philosophical problems. Every metaphysician should read it and emulate Maudlin's method, even when disagreeing with his conclusions. --Richard Healey, Notre Dame Philosophical Reviews
