Discussion of moral explanation has reached animpasse, with proponents of contemporaryethical naturalism upholding the explanatoryintegrity of moral facts and properties, andopponents – including both anti-realists andnon-naturalistic realists – insisting thatsuch robustly explanatory pretensions as moraltheory has be explained away. I propose thatthe key to solving the problem lies in thequestion whether instances of moral propertiesare causally efficacious. It is argued that,given the truth of contemporary ethicalnaturalism, moral properties are causallyefficacious if the properties of the specialsciences are. Certain objections are rebuttedinvolving (...) the nature of causation, on the onehand, and putative special features of themoral realm, on the other. (shrink)

The overarching aim of this essay is to argue that moral realists should be "causalists" or claim that moral facts of certain kinds are causally efficacious. To this end, I engage in two tasks. The first is to develop an account of the sense in which moral facts of certain kinds are causally efficacious. After having sketched the concept of what I call a "configuring" cause, I contend that the exercise of the moral virtues is plausibly viewed as a configuring (...) cause. The second is to show that the causalist position I develop can withstand objections inspired by the work of Robert Audi and Jaegwon Kim. (shrink)

The central purpose of this essay is to consider some of the more prominent reasons why realists have rejected the Humean theory of motivation. I shall argue that these reasons are not persuasive, and that there is nothing about being a moral realist that should make us suspicious of Humeanism.
