Cassius Dio (c. 163-235)
“I believe that far more wrongs are put right by kindness than by harshness. Those who forgive are loved not only by those to whom they have shown mercy – and these men will even strive to return the kindness – but they are also respected and revered by all the rest, who will not lightly venture to harm them.”
- From Cassius Dio’s The Roman History (Book 55, chapter 16), translated by Ian Scott-Kilvert (Penguin Classics, 1987).
