The Greek word euphuia, a finely tempered nature, gives exactly the notion of perfection as culture brings us to perceive it; a harmonious perfection, a perfection in which the characters of beauty and intelligence are both present, which unites "the two noblest of things" - as Swift most happily calls them in his Battle of the Books, "the two noblest of things, sweetness and light."
"Culture and Anarchy". Book by Matthew Arnold, 1869.
