„You can't make a silk purse out of a sow's ear, and you can't change human nature from intelligent self-interest into pure idealism—not in this life; and if you could, what would be left for paradise?“
— Joseph Gurney Cannon American politician 1836 - 1926
Maxim quoted in a tribute to Cannon on his retirement, reported in The Sun, Baltimore, Maryland (March 4, 1923); Congressional Record (March 4, 1923), vol. 64, p. 5714.
