As the Deity has given us Greeks all other blessings in moderation, so our moderation gives us a kind of wisdom which is timid, in all likelihood, and fit for common people, not one which is kingly and splendid. This wisdom, such as it is, observing that human life is ever subject to all sorts of vicissitudes, forbids us to be puffed up by the good things we have, or to admire a man's felicity while there is still time for it to change.
"Solon". Book by Plutarch, ch. 27; translation by Bernadotte Perrin, 1497.
