Are the objects of the affections, of desire, effort, choice, that is to say everything to which we at- tach value, real? Yes, if they can be warranted by knowledge jif we can know objects having these value properties, we are justi- fied in thinking them real. But as objects of desire and purpose they have no sure place in Being until they are approached and validated through knowledge. The idea is so familiar that we overlook the unexpressed premise upon which it rests, namely that only the completely fixed and unchanging can be real.
