Famous quotes containing the word science:
“You are all fundamentalists with a top dressing of science. That is why you are the stupidest of conservatives and reactionists in politics and the most bigoted of obstructionists in science itself. When it comes to getting a move on you are all of the same opinion: stop it, flog it, hang it, dynamite it, stamp it out.”
—George Bernard Shaw (1856–1950)
“Vanity of science. Knowledge of physical science will not console me for ignorance of morality in time of affliction, but knowledge of morality will always console me for ignorance of physical science.”
—Blaise Pascal (1623–1662)
