Consequently, if we mean to find either the man who has the sacred cup, or the bye, or our best guide to the famous city of Corinth, we must absolutely go to and examine them all, trying them carefully, stripping and comparing them; the truth will be hard enough to find, even so. If I am to take any one’s advice upon the right philosophy to choose, I insist upon his knowing what they all say; every one else I disqualify; I will not trust him while there is one philosophy he is unacquainted with; that one may possibly be the best of all. If some one were to produce a handsome man, and state that he was the handsomest of mankind, we should not accept that, unless we knew he had seen all men; very likely his man is handsome, but whether the handsomest, he has no means of knowing without seeing all. Now we are looking not simply for beauty, but for the greatest beauty, and if we miss that, we shall account ourselves; no further than we were; we shall not be content with chancing upon some sort of beauty; we are in search of a definite thing, the supreme beauty, which must necessarily be one.
