An excellent piece of analytic metaphysics: the care, precision, detail, and breadth of Turner's presentation constitute a model for how to develop a metaphysical idea. Anyone intrigued by the basic factalist idea will learn an immense amount about it from this book, and would be unwise to attempt to develop or evaluate it without thinking through the body of related issues that Turner insightfully explores...Turner's work addresses, from a novel perspective, questions the definitive answers to which might well yield deep insight, and it provides a vivid sense of answers these questions plausibly might have.
