The Quotable Sir John

As quoted by Diogenes Laërtius in Life of Pittacus, i. 76, citing Heraclitus as his source.
Pittacus made this remark to justify his release of his captured enemy Alcaeus.
According to William Shepard Walsh, in Handy-book of Literary Curiosities (1892), p. 392, Epictetus, quoting from the same source, gives the phrase thus: "Forgiveness is better than punishment; for the one is proof of a gentle, the other of a savage, nature."

Variant: What does labor want? We want more school houses and less jails. More books and less guns. More learning and less vice. More leisure and less greed. More justice and less revenge. We want more … opportunities to cultivate our better natures.
