Hayya, or modesty, is not artificial in the sense in which, for instance, obedience to many of the social laws may be called artificial. Just as wisdom and morality are learned of nature, so also does modesty come from nature. It is a quality of beauty. It is the essential quality of beauty which the great artist understands. By veiling his thought he conveys an impression many times more beautiful than does the artist who is unskilled in expression.
