Epictetus, Golden Sayings 88

Which of us does not admire what Lycurgus the Spartan did? 

A young citizen had put out his eye, and been handed over to him by the people to be punished at his own discretion. 

Lycurgus abstained from all vengeance, but on the contrary instructed and made a good man of him. 

Producing him in public in the theater, he said to the astonished Spartans: 

"I received this young man at your hands full of violence and wanton insolence; I restore him to you in his right mind and fit to serve his country."
