  These reasons do not apply to the concept of goodness. First, this concept does not seem to be metaphysically superficial or incomplete in the way that the concept of heat or water is. When we think of something as good we do not think of it merely as having certain effects on us, or as picking out certain surface properties the property of goodness has, but think of it as having a distinctive characteristic. Not all intuitionists agreed with Moore that nothing could be said about the nature of this characteristic (though they all agreed that this is a non-natural property). A. C. Ewing, for example, maintained that the characteristic we have in mind when we think of something as being good is the property it has of being the fitting object of a pro-attitude. If this, or something like it, is correct, then the concept of goodness does not merely describe certain properties goodness has, but aspires to tell us what goodness  is.[19] It does not, therefore, call for a metaphysically deeper account from some other source in the way that the concept of heat or water does.
