 Non-naturalism would seem to have less bearing on a further question: whether there are moral principles connecting one moral property to another. This issue is at play in Ross’s rejection of Moore’s claim that the right action is the action which maximizes the good. Even if Ross relied on Moore’s own “open question” strategy to challenge Moore’s utilitarian principle, it is nevertheless the case that Moore’s principle is at least consistent with non-naturalism. More recently, philosophers sympathetic to particularism have divided over the availability of intra-moral principles. Some are content to allow that a claim such as, “the fact that an action is just is a reason in its favour”, is true and informative (cf. McNaughton and Rawling 2000). Others propose a more radical particularism according to which even intra-moral principles—that is, principles linking one moral concept with another—are unavailable (cf. Dancy 2004: ch 7).
