  Intuitionists may respond to this objection by drawing on a recent version of Ewing’s fitting attitude analysis of goodness. Ewing thought that to be good is to be the object of a fitting pro-attitude. T. M. Scanlon has argued that goodness is to be understood as something’s having properties that give us reason to have a pro-attitude towards it (1998, 95), and like the intuitionist view about goodness and rightness, he thinks that the notion of a reason cannot be understood in other, non-normative terms (1998, 17). So his view is something intuitionists can accept. If they do, then there would seem to be no mystery about the magnetism of the good. If coming to see that something is good is coming to see that we have reason to have a pro-attitude towards it, then it would be no surprise if rational individuals come to have a pro-attitude towards perceived goods, any more than it would be surprising if rational beings come to do what they judge they ought to do. If one has Humean leanings one might want an explanation of how a judgement that one has reason to have an attitude, or that one ought to do something, can by itself motivate. But then the problem is not with the non-natural nature of moral properties, but is one within moral psychology, and involves the debate between those who endorse a Humean theory of motivation, and those who deny this.
