The moralist must not despise forms of art which have no ulterior, utilitarian value; but he must insist that no enjoyment of art is really, in the long run, good for man which influences his life in the unwholesome ways we have indicated. Since morality is that way of life that gives it its greatest worth, indulgence in art at the expense of morality is seizing an immediate but lesser good at the expense of an ultimately greater good. Practically, however, the censorship of art is the most delicate of matters, because the influence of the same work of art on one person may be widely different from its effect upon another. A play or a picture that pleases or even inspires one spectator may be disastrous to his neighbor. And it is always difficult to decide between the claims of an immediate good and the warnings of dangers that may lurk therein. But we universally acknowledge the duty of some censorship, by prohibiting the most openly tempting pictures, plays, and literature. And there can be no doubt that this supervision should be carried further than it now is. The most pressing contemporary problem is that concerning the stage. [Footnote: See J.

No other form of art now tolerated so frequently overstimulates the sex instinct. The scant costumes permitted, with their conscious endeavor to reveal the feminine form as alluringly as possible, the voluptuous dances and ballets, the jokes, stories, and suggestive gestures, and often the low moral tone of the play, making light of sacred matters and encouraging lax ideas on sex relations, are powerful excitants. Many theaters frankly pander to the desire for such stimulation; and they are crowded. For while human nature remains as it is, the young will flock whither they can find sex excitement. Scarcely less dangerous are the magazines and books that by their pictures and their stories play up to this eternal instinct. Even painters in oils often use this drawing card; the Paris salons have always a considerable sprinkling of nudes, in all sorts of voluptuous attitudes, making a frank appeal to desire. French literature abounds in books, some of great literary merit, that exploit this aspect of human nature; but in every tongue there are the Boccaccios and the Byrons.
