Religion is a great force - the only real motive force in the world; but what you fellows don't understand is that you must get at a man through his own religion and not through yours. George Bernard Shaw
If when we judged others, our real motive was to destroy evil, we should look for evil where it is certain to be found, and that is in our own hearts. But if we are on the look-out for evil in others, our real motive is obviously to justify ourselves. Dietrich Bonhoeffer
Most men have nothing in their heads but their physical needs; put them on a desert island with nothing to occupy their minds and they would go insane. They lack real motive. The curse of civilization is boredom. Colin Wilson
