Famous quotes containing the words proportional and/or reasoning:
“The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.”
—Aldous Huxley (1894–1963)
“We put [young children] into kindergarten where their reasoning powers are ruined; or, if we can afford it, we buy Montessori outfits that were invented for semi-imbeciles in Italian slums; or we send them to outdoor schools and give them prizes for sleeping.”
—Katharine Fullerton Gerould (1879–1944)
