Famous quotes containing the word rule:
“Men conceive themselves as morally superior to those with whom they differ in opinion. A Socialist who thinks that the opinions of Mr. Gladstone on Socialism are unsound and his own sound, is within his rights; but a Socialist who thinks that his opinions are virtuous and Mr. Gladstone’s vicious, violates the first rule of morals and manners in a Democratic country; namely, that you must not treat your political opponent as a moral delinquent.”
—George Bernard Shaw (1856–1950)
