 Nevertheless, it is generally agreed by all sides that such “supervenience functions” should not count as moral principles. The grounds offered for this are various, but include that such generalizations contain much potentially irrelevant information, that they are massively disjunctive, and that they lack explanatory import (cf. Little 2000; Dancy 2004; McKeever and Ridge 2005). The idea is that to be a successful moral principle (qua standard) requires more than a true or even necessary connection between the descriptive and the moral. The connection must be explanatory and not cite irrelevant features in the antecedent either. Even those who gesture at supervenience in mounting arguments for generalism concede that a successful argument requires significant additional semantic or epistemological premises (see below, and cf. Jackson, Pettit, &amp; Smith 2000).
