As soon as ever the art of the upper classes separated itself from universal art, a conviction arose that art may be art and yet be incomprehensible to the masses. And as soon as this position was admitted, it had inevitably to be admitted also that art may be intelligible only to the very smallest number of the elect, and, eventually, to two, or to one, of our nearest friends, or to oneself alone, which is practically what is being said by modern artists: I create and understand myself, and if any one does not understand me, so much the worse for him.
