Even if moral facts are sui generis (Moore, in Blackburn), and distinct from other facts about the natural world, they must still exert a sort of impulse on those who believe them, they cause spark a conviction that they are not only true, but that an ought should follow. (A similar problem exists in utilitarian philosophy, where usually not only one’s own happiness but the happiness of all people, or a given society, must be considered to be considered a reason to act a certain way.) Moore’s cognitivism claims that these supposed moral facts do carry this impulse or sentiment, but it is then unclear why it should be the intuited truth of the fact which is convincing rather than the impulse of the moral claims alone. The cognitivist account is not needed to explain the motivational force of a moral claim, and the reason why the claim is
