For to err in opinion, though it be not the part of wise men, is at least human. — Plutarch. Greek philosopher and historian (c. AD 40 – 120s)
Nor is it always in the most distinguished achievements that men's virtues or vices may be best discovered: but very often an action of small note, a short saying, or a jest, shall distinguish a person's real character more than the greatest sieges, or the most important battle.
