The demand for purity which aims at non-sensuousness—or supersensuousness—may perhaps provide protection from minor dangers. In great ones it will be as futile as a hedge against a forest fire. No obstructing of appetites, but only their release in other directions, can really purify them. Passions can be curbed only by means of stronger passions. In the same appetite and the same passion in which the danger lies, in the instinct of love itself, we have the true starting-point for its ennobling. He to whom the destruction of this instinct is a passionate desire possesses in this passion itself a prospect of attaining his unnatural end. He, again, who does not wish to kill, but only to control the sexual instinct, will become, in his struggle against this desire—still immeasurably stimulated through heredity and social custom—a strong and proud conqueror only when he imagines and finally experiences unity in love. Assuredly also secondary expedients are to be found. Before all, that of acquiring the instinct of chastity from parents; of being strengthened and protected from childhood against the dangers of callousness as well as those of softness; of being instructed in a refined and gentle way of the great purpose and great dangers of sexual destiny; of receiving impressions through public opinion of the possibility of self-control and its importance to the happiness of the individual himself and of the race; of avoiding the abuse of means of enjoyment, especially of intoxicating liquors, which both directly and indirectly weaken the will-power in the case of sexual, as of all other kinds of, temptation. It is beyond question that noble sport, dancing, and games—and they are only noble when practised finely and worthily, with the mind as well as the body—are a means of replacing and controlling the sexual instinct. Equally certain is it that bodily and mental labour, whether undertaken independently or as a participation in some form of social endeavour, is important as occupying and consuming the sexual powers in a substituted form. All genuine artistic enjoyment is in the highest degree important for the ennobling of sexual life. But all this self-discipline, all these aids from the world of beauty and labour, all this cultivation of the body to strength and beauty, will be as lines without a centre so long as they do not all lead in the direction of love—love, which certain preachers of morality would leave altogether outside the question, as though even it were a danger and a temptation. No one would venture to deny that healthy habits of life and strict self-control may be elevating for the individual, even if love means nothing in his life. But life in its entirety gains nothing by the production of hardened or harassed ascetic types, which by exhausting bodily exercise, by reading that leaves the imagination arid, and by art that smothers nudity, have succeeded in lulling to sleep the sensuousness which, nevertheless, will perhaps some
