Famous quotes containing the word conditions:
“My dear young friend ... civilization has absolutely no need of nobility or heroism. These things are symptoms of political inefficiency. In a properly organized society like ours, nobody has any opportunities for being noble or heroic. Conditions have got to be thoroughly unstable before the occasion can arise.”
—Aldous Huxley (18941963)
