What you receive from others is a testimony to their virtue; but all that you do for others is the sign and clear indication of your own.
Giordano BrunoMy son, I do not say these are foals and those asses, these little monkeys and those great baboons, as you would have me do. As I told you from the first, I regard them as earth's heroes. But I do not wish to believe them without cause, nor to accept those propositions whose antitheses (as you must have understood if you are not both blind and deaf) are so compellingly true.
