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."
— Matthew Arnold
Sweetness
