The vast majority of men, however, are not so developed, and are not intended to carry out such a life. Yet, for them, too, this process must be to some extent adopted. It is largely a matter of common-sense. The animal exercises no restraint; whenever the sex-impulse arises, it is satisfied--so far, of course, as the opportunity is provided. But as we trace the conduct of the more developed species from savage to civilized man we are conscious of a new element of will-power. The influences which cause this power to come into operation may vary. Religious obligations, considerations of business, social, or intellectual responsibilities, help to intervene. An intelligent man simply cannot afford to give vent to sex proclivities every time they arise; he has other interests which must of necessity at many times of the day have the first claim. Imagine a man who sacrificed a business engagement for some sex gratification! Often in the recent war a man, however strong his sexual emotions, would be forced to cast away all ideas of sex in order to dodge a shell; his mind for continuous periods would be so driven with anxieties and the stress of responsibility that sex would sink into insignificance. This is an extreme instance, but to a lesser degree it is what is happening to everyone who leads a normal life. The more developed the man, the wider his intellectual interests; and it is precisely in this capacity to exercise his will-power that he proves his superiority over the animal. This process of transmutation is the remedy which must be applied in cases where men find themselves the victims of sexual emotion out of all true proportion, whether in married or unmarried life. Mere repression is useless; it is actually harmful. But the mind must be switched off to dig a thought-passage in other directions, in non-sexual interests. Where there is undue sex obsession there is disease. And this mental transference is the chief cure. Really, this transmutation is a diffusing of the sex-force into a wide general area. The man is no longer concentrating all his sex-energy in love for one particular person; he is beginning sexually to love all humanity. He is finding sexual expression in the "non-sexual" forms of art or nature. He is still in love--but in love with love, rather than with one separate personal fragment of the whole. But with the ordinary man, there must remain a balance of sexual inclination which cannot entirely be transmuted. Here we encounter the first process, and our problem, particularly in non-married life, becomes acute. Is it possible, and is it healthy, to deny the sex-instincts all satisfaction? Different answers are given by religious advisers and by men of the world, while even in the ranks of the medical profession there is no consensus of opinion. I suggest that there is only one general principle which can be our guide.
