The most interesting faces generally oscillate between charm and crookedness. There is a tyranny about perfection, a certain tedium even, something that asserts itself with all the dogmatism of a scientific formula. The more tempting kind of beauty has only a few angles from which it may be seen, and then not in all lights and at all times. It flirts dangerously with ugliness, it takes risks with itself, it does not side comfortably with mathematical rules of proportion, it draws its appeal from precisely those details that also lend themselves to ugliness.
