Possibly, and indeed probably, as the sentiment of common life and common interest grows, and the capacity for true companionship increases with the decrease of self-regarding anxiety, the importance of the mere sex-act will dwindle till it comes to be regarded as only one very specialised factor in the full total of human love. There is no doubt that with the full realisation of affectional union the need of actual bodily congress loses some of its urgency; and it is not difficult to see in our present-day social life that the want of the former is (according to the law of transmutation) one marked cause of the violence and extravagance of the lower passions. But however things may change with the further evolution of man, there is no doubt that first of all the sex-relation must be divested of the sentiment of uncleanness which surrounds it, and rehabilitated again with a sense almost of religious consecration; and this means, as I have said, a free people, proud in the mastery and the divinity of their own lives, and in the beauty and openness of their own bodies.
Sex is the allegory of Love in the physical world. It is from this fact that it derives its immense power. The aim of Love is non-differentiation—absolute union of being; but absolute union can only be found at the centre of existence. Therefore whoever has truly found another has found not only that other, and with that other himself, but has found also a third—who dwells at the centre and holds the plastic material of the universe in the palm of his hand, and is a creator of sensible forms.
Similarly the aim of sex is union and non-differentiation—but on the physical plane,—and in the moment when this union is accomplished creation takes place, and the generation (in the plastic material of the sex-elements) of sensible forms.
In the animal and lower human world—and wherever the creature is incapable of realising the perfect love (which is indeed able to transform it into a god)—Nature in the purely physical instincts does the next best thing, that is, she effects a corporeal union and so generates another creature who by the very process of his generation shall be one step nearer to the universal soul and the realisation of the desired end. Nevertheless the moment the other love and all that goes with it is realised the natural sexual love has to fall into a secondary place—the lover must stand on his feet and not on his head—or else the most dire confusions ensue, and torments æonian.
Taking all together I think it may fairly be said that the prime object of Sex is union, the physical union as the allegory and expression of the real union, and that generation is a secondary object or result of this union. If we go to the lowest material expressions of Sex—as among the protozoic cells—we find that they, the cells, unite together, two into one; and that, as a result of the nutrition that ensues, this joint cell after a time (but not always) breaks up by fission into a number of progeny cells; or if on the other hand we go to the very highest expression of Sex, in the sentiment of Love, we find the latter takes the form chiefly and before all else of a desire for union, and only in lesser degree of a desire for race-propagation.
I mention this because it probably makes a good deal of difference in our estimate of Sex whether the one function or the other is considered primary. There is perhaps a slight tendency among medical and other authorities to overlook the question of the important physical actions and reactions, and even corporeal modifications, which may ensue upon sexual intercourse between two people, and to fix their attention too exclusively upon their child-bearing function; but in truth it is probable, I think, from various considerations, that the spermatozoa pass through the tissues and affect the general body of the female, as well as that the male absorbs minutest cells from the female; and that generally, even without the actual Sex-act, there is an interchange of vital and etherial elements—so that there is a kind of generation taking place in each other, as well as that more specialised generation which consists in the propagation of the race.
At the last and taking it as a whole one has the same difficulty in dealing with the subject of Love which meets one at every turn in modern life—the monstrous separation of one part of our nature from another—the way in which—no doubt in the necessary course of evolution—we have cut ourselves in twain as it were, and assigned "right" and "wrong," heaven and hell, spiritual and material, and other violent distinctions, to the separate portions. We have eaten of the Tree of Knowledge of good and evil with a vengeance! The Lord has indeed driven us out of Paradise into the domain of that "fabro vulcano" who with tremendous hammer-strokes must hammer the knowledge of good and evil out of us again. I feel that I owe an apology to the beautiful god for daring even for a moment to think of dissecting him soul from body, and for speaking as if these artificial distinctions were in any wise eternal. Will the man or woman, or race of men and women, never come, to whom love in its various manifestations shall be from the beginning a perfect whole, pure and natural, free and standing sanely on its feet?
