"Beauty in its largest and profoundest sense is one expression for the universe; God is the all-fair. Truth and goodness and beauty are but different faces of the same All. But beauty in Nature is not ultimate. It is the herald of inward and eternal beauty, and is not alone a solid and satisfactory good.

And with these forms the spells of persuasion, the keys of power, are put into his hands."
