"At times we need a rest from ourselves by looking upon, by looking down upon, ourselves and, from an artistic distance, laughing over ourselves or weeping over ourselves; we must discover the hero no less than the fool in our passion for knowledge, we must occasionally find pleasure in our folly, or we cannot continue to find pleasure in our wisdom! Precisely because we are at bottom grave and serious human beings—really more weights than human beings—nothing does us as much good as a fool's cap: we need it in relation to ourselves—we need all exuberant, floating, dancing, mocking, childish, and blissful art lest we lose the freedom above things that our ideal demands of us. It would mean a relapse for us, with our irritable honesty, to get involved entirely in morality and, for the sake of the over-severe demands we make on ourselves in these matters, to become virtuous monsters and scarecrows. We should be able also to stand above morality—and not only to stand with the anxious stiffness of a man who is afraid of slipping and falling at any moment, but also to float above it and play! How then could we possibly dispense with art, and with the fool?— And as long as you are in any way ashamed before yourselves, you do not yet belong with us!"
(Nietzsche, Den glada vetenskapen, aforism nr. 107)
