" You will always be the prey or the plaything of the devils and fools in this world, if you expect to see them going about with horns or jangling their bells. And it should be borne in mind that, in their intercourse with others, people are like the moon: they show you only one of their sides. Every man has an innate talent for . . . making a mask out of his physiognomy, so that he can always look as if he really were what he pretends to be . . . and its effect is extremely deceptive. He dons his mask whenever his object is to flatter himself into some one’s good opinion; and you may pay just as much attention to it as if it were made of wax or cardboard. —Arthur Schopenhauer "
