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)
“Education is a necessity, it helps to understand life. Like that compagnero in Cuba who talked about politics, back when they were on strike. He knew many things, that hijo de puta, and he unraveled the most confusing situations in a marvelous way. You could see each point in front of you on the line of his reasoning like rinsed laundry set up to dry; he explained things to you so clearly that you could grasp it like a good hunk of bread with your hand.”
—Jacques Roumain (1907–1945)
