Letters 24.5

Mucius put his hand into the fire. It is painful to be burned; but how much more painful to inflict such suffering upon oneself! Here was a man of no learning, not primed to face death and pain by any words of wisdom, and equipped only with the courage of a soldier, who punished himself for his fruitless daring; he stood and watched his own right hand falling away piecemeal on the enemy’s brazier, nor did he withdraw the dissolving limb, with its uncovered bones, until his foe removed the fire. He might have accomplished something more successful in that camp, but never anything more brave. See how much keener a brave man is to lay hold of danger than a cruel man is to inflict it: Porsenna was more ready to pardon Mucius for wishing to slay him than Mucius to pardon himself for failing to slay Porsenna!
