Both optimists and pessimists contribute to society. The optimist invents the aeroplane, the pessimist the parachute.
George Bernard ShawA life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing.
George Bernard ShawYou 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
