Abstract
Geach's problem, the problem of accounting for the fact that judgements expressed using moral terms function logically like other judgements, stands in the way of most noncognitive analyses of moral judgements. The non-cognitivist must offer a plausible interpretation of such terms when they appear in conditionals that also explains their logical interaction with straightforward moral assertions. Blackburn and Gibbard have offered a series of accounts each of which interprets such conditionals as expressing higher order commitments. Each then invokes norms for the coherent acceptance of attitudes to explain why we hold certain combinations inconsistent. Against these accounts the paper presses two related objections: (1) The norms needed to do the explanatory work cannot be strong enough to do that work without also ruling clearly consistent attitudes inconsistent. And (2), the norms of rational attitude acceptance do not neatly track the distinction between consistent and inconsistent attitudes.
