  There may be a problem for those more sophisticated forms of non-cognitivism according to which moral terms have both descriptive and prescriptive or expressive meaning when these are coupled with reliance on the Open Question Argument. Suppose that the postulated extra expressive or prescriptive component in moral terms explains why competent speakers would not equate moral terms with descriptive analyses of them and that it also explains why we cannot validly infer a moral conclusion from non-moral premises. If moral terms have descriptive meaning in addition to their non-cognitive element one should be able to validly argue in the other direction. The problem is that competent speakers are just as likely to wonder about the validity of such inferences as they are to wonder about those going from descriptive premises to normative conclusions. If the openness of such questions to competent speakers is sufficient to refute claims of meaning equivalence, it should here refute theories which include descriptive meanings in an otherwise non-cognitive analysis. If the arguments that lead non-cognitivists to postulate descriptive meaning are sufficiently compelling it seems they should not rely on the open question argument to support their views. Woods (2015) presses a related worry against even non-hybrid non-cognitivist theories. If the conventional function of moral terms is to express attitudes, it should seem Moore-paradoxical (that is pragmatically incoherent) to deny that one approves of the things one believes good or right. But many such claims don’t seem pragmatically incoherent.
