Publisher's Synopsis
This book critically examines philosophical naturalism, evaluates the prospects for naturalizing such normative properties as being a reason, and proposes a theory of action-explanation. This theory accommodates an explanatory role for both psychological properties, such as intention, and normative properties, such as having an obligation or being intrinsically good. The overall project requires distinguishing philosophical from methodological naturalism, arguing for the possibility of a scientifically informed epistemology that is not committed to the former, and freeing the theory of action-explanation from dependence on the reducibility of the mental to the physical. The project also requires distinguishing explanatory power from causal power. Explanations - at least of the kinds central in both science and everyday life - are conceived as constitutively aimed at yielding understanding. The book sketches a view of understanding that clarifies the nature of explanation, and, partly in the light of this relation, it provides a broad account of causal power on which psychological properties can possess it without being reducible to physical properties. The book concludes with an account of how, especially in the normative domain, explanations can be a priori. They may use a priori generalizations to provide understanding of what they explain, and they may clarify a priori propositions, or both. They may achieve these aims not only in logic and pure mathematics, but also in the realm of moral and other normative phenomena. The overall result is to show how philosophical understanding of both natural and normative phenomena is possible through integration with a scientific habit of mind that does not require a narrow empiricism in epistemology or a reductive naturalism in metaphysics or the theory of explanation.
