“This philosopher was a person very different, both in his life and
manners, from other men. If it chanced at any time that he was
inflamed with anger, he would take his harp, play upon, and sing to
it; saying, as often as he was asked the cause of his so doing, ‘That
by this means he found himself reduced to the temper of his former
mildness.’”
