“We would be a lot safer if the Government would take its money out of science and put it into astrology and the reading of palms.... Only in superstition is there hope. If you want to become a friend of civilization, then become an enemy of the truth and a fanatic for harmless balderdash.”
—Kurt Vonnegut, Jr. (b. 1922)
“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)
“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.”
—Anton Pavlovich Chekhov (1860–1904)
