Gifted with great fortitude to bear the evils afflicting another.
When Zeno was told that one of his enemies was no more he was
observed to be deeply moved. "What!" said one of his disciples, "you
weep at the death of an enemy?" "Ah, 'tis true," replied the great
Stoic; "but you should see me smile at the death of a friend."
