Arrian (lived approx. 90-173+)
“Most people, if they know they have done wrong, foolishly suppose they can conceal their error by defending it, and finding a justification for it; but in my belief there is only one medicine for an evil deed, and that is for the guilty man to admit his guilt and show that he is sorry for it.”
- The Campaigns of Alexander (Book 7, approximately section 29) by Arrian, translated by Aubrey de Sélincourt and revised by J. Hamilton. New York; Penguin Classics, 1971.
