John W. Carroll undertakes a careful philosophical examination of laws of nature, causation, and other related topics. He argues that laws of nature are not susceptible to the sort of philosophical treatment preferred by empiricists. Indeed, he shows that empirically pure matters of fact need not even determine what the laws are. Similar, and even stronger, conclusions are drawn about causation. Replacing the traditional view of laws and causation as requiring some kind of foundational legitimacy, the author argues that these phenomena are inextricably intertwined with everything else. This distinctively clear and detailed discussion of what it is to be a law will be valuable to a broad swathe of philosophers in metaphysics, epistemology, the philosophy of mind, and the philosophy of science.
