tions is one of the cardinal facts in our human constitution. Polarizing and magnetizing us as they do, we turn towards them and from them, we seek them, hold them, hate them, bless them, just as if they were so many concrete beings. And beings they are, beings as real in the realm which they inhabit as the changing things of sense are in the realm of space.
Plato gave so brilliant and impressive a defense of this common human feeling, that the doctrine of the reality of abstract objects has been known as the platonic theory of ideas ever since. Abstract Beauty, for example, is for Plato a perfectly definite individual being, of which the intellect is aware as of something additional to all the perishing beauties of the earth. "The true order of going," he says, in the often quoted passage in his 'Banquet,' "is to use the beauties of earth as steps along which one mounts upwards for the sake of that other Beauty, going from one to two, and from two to all fair forms, and from fair forms to fair actions, and from fair actions to fair notions, until from fair notions he arrives at the notion of absolute Beauty, and at last knows what the essence of Beauty is."[1] In our last lecture we had a glimpse of the way in which a platonizing writer like Emerson may treat the abstract divineness of things, the moral structure of the universe, as a fact worthy of worship. In those various churches without a God which to-day are spreading through the world under the name of ethical societies, we have a similar worship of the abstract divine, the moral law believed in as an ultimate object. 'Science' in many minds is genuinely taking the place of a religion. Where this is so, the scientist treats the 'Laws of Nature' as objective facts to be revered.
