Famous quotes containing the words reaction and/or wheel:
“More and more, when faced with the world of men, the only reaction is one of individualism. Man alone is an end unto himself. Everything one tries to do for the common good ends in failure.”
—Albert Camus (1913–1960)
“Helpless, unknown, and unremembered, most human beings, however sensitive, idealistic, intelligent, go through life as passengers rather than chauffeurs. Although we may pretend that it is the chauffeur who is the social inferior ... most of us, like Toad of Toad Hall, would not mind a turn at the wheel ourselves.”
—Ralph Harper (b. 1915)
