Another means which the artist may employ in order to win us is the appeal of sense. However repellent be the objects which he represents, if he can clothe them in a sensuous material which will charm us, he will have exerted a powerful countervailing force. We have already had occasion to observe this in our first chapter. Through the call of sense we are invited to enter and are made welcome at the very threshold of the work of art. Engaging lines, winsome colors and tones, and compelling rhythms can overcome almost any repugnance that we might otherwise feel for the subject-matter. Their primary appeals are superior to all the reservations of civilization. No wonder that the stern moralists who would keep beauty for the clean and holy have been afraid of art! Yet the delight of sense, because its emotional effect is diffused, does not interfere with the contemplative serenity of art, as unbridled passion does; it even quiets passion by diverting the attention to itself; hence may always be employed by the artist. A good example of the aesthetic fascination of sensation is Von Stuck's "Salome" in the Art Institute of Chicago. For all normal feeling, Salome dancing with the head of John the Baptist is a revolting object; yet how beautiful the artist has made his picture through the simple loveliness of gold and red! It would be a mistake, however, to infer the indifference of the subject-matter in art. The creation of a work of art is based on a primary aesthetic experience of nature or human life, and not everything is capable of producing such an experience in all men. The subject must be one towards which the artist or spectator is able to take the sthetic attitude of emotional, yet free, perception. Some people are unable to lay aside their moral prepossessions towards certain phases of life or even towards representation of them; the idea affects them as would the reality. For such people even the genius of a Beardsley is too feeble to create an experience of beauty out of the material with which he works. Or again, some people cannot objectify their sensual egotistic impulses and feelings; for them the reading of a Boccaccio, for example, is only a substitute for such feelings, not a means of insight into them. It requires a robust intellectual attitude, a predominance of mind over feeling and instinct, aesthetically to appreciate some works of art. But for those who can receive it, the representation of any phase of life may afford an aesthetic experience, may create a thing good to know, if only it be mastered by the mind and embodied in a charming form. The charm of sense together with the satisfaction of insight are sufficient to explain the conquest of evil by art. Yet further means have been employed--the special appeals of the tragic, pathetic, and comic.
