 The tension being discussed here could be resolved if we were to accept a certain sort of internalist thesis about moral norms, a thesis that Michael Smith calls “rationalism” (Smith 1994, p. 62), though it would need to be affirmed in a somewhat stronger form than that which Smith affirms. The rationalist thesis as Smith describes it holds no more than that the fact that an act is morally right for an agent to perform entails that the agent has a good reason for performing it. The strengthened rationalist thesis holds that the fact that an action is the morally best action for an agent to perform entails that it is the action that the agent has most reason to perform. What is being supposed here is that rationality, vis-a-vis morality, is very demanding: moral requirements just are rational requirements, so that a failure to act morally is a failure to act rationally.
