Famous quotes containing the word human:
“Vanity, or to call it by a gentler name, the desire of admiration and applause, is, perhaps, the most universal principle of human actions.... Where that desire is wanting, we are apt to be indifferent, listless, indolent, and inert.... I will own to you, under the secrecy of confession, that my vanity has very often made me take great pains to make many a woman in love with me, if I could, for whose person I would not have given a pinch of snuff.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Worst of all, there is no sign of any relaxation of antisemitism. Logically it has nothing to do with Fascism. But the human race is imitative rather than logical; and as Fascism spreads antisemitism spreads.”
—George Bernard Shaw (1856–1950)
