When Anaxagoras was told of the death of his son, he only said, "I knew he was mortal." So we in all casualties of life should say "I knew my riches were uncertain, that my friend was but a man." Such considerations would soon pacify us, because all our troubles proceed from their being unexpected.
PlutarchA traveller at Sparta, standing long upon one leg, said to a Lacedaemonian, "I do not believe you can do as much." "True," said he, "but every goose can."
