But apart from these extreme instances which may be due to special causes, the general principle of compensation through opposites is very obvious and marked. The fluffy and absurd little woman is selected by a tall and statuesque grenadier; the tall and statuesque lady is made love to by a man who has to stand on a chair to kiss her; the society elegant takes to a snuffy and preposterous professor; the bookish scholar (as in Jude the Obscure) to a mere whore; the clever beauty (as in L’homme qui rit) to a grinning clown; and of course the ‘wicked’ man is always saved by the saintly woman. The masculine, virago-like woman, on the other hand, finds a man who positively likes being beaten with a stick; and the miaowling, aimlessly amiable female gets a bully for a husband (and one can only say, “Serve them both right”)... Finally, the well-formed aquiline nose insists on marrying a pug nose—and this apparently quite regardless of what the other bodily and mental parts may be, or what they may want.

Everyone knows cases of quite young men who only love women of really advanced age, beyond the limit of childbirth; and these are curious because they seem to point to impelling forces in love beyond and independent of generation and race-perpetuation, and therefore lying outside of the Schopenhauerian explanations. And similarly we all know cases of young girls who are deadly earnest in their affection for quite old men, men who might well be their fathers or grandfathers, but hardly, one would think, their husbands. In these cases it looks as if the young thing needs and seeks a parent as well as a lover—the two in one, combined. And where such love is returned, it is returned in a kind of protective love, rather than an amative love—or at any rate as a love in which the protective and amative characters are closely united.

Similarly there are numbers of cases in which mature or quite grown men and women only love (passionately and devotedly) boys and girls of immature age—their love for them ceasing from its ardor and intensity when the objects of devotion reach the age, say, of twenty or twenty-one. And in many of these cases the love is ardently returned. Here, again, it is evidently not a case of generation or race-perpetuation, but simply of compensation—the young thing requiring the help and protection of the older, and the older requiring an outlet for the protective instinct—a case of exchange of essences and qualities which (if at all decently and sensibly managed) might well go to the building up of a full and well-rounded life on either side.

In all these cases (and the above are of course only samples out of thousands) we seem to see an effort of the race-life to restore its total quality—to restore it through the operation of love—either by completing and rounding out the life of the individuals concerned, or by uniting some of their characteristics in the progeny. I say ‘seem to see,’ because we cannot well suppose that this gives a complete account of the matter, or that it explains the whole meaning of Love; but it at any rate suggests an important aspect of the question. The full quality of the race-life is always building itself up and restoring itself in this manner. A process of Regeneration is always going on. And this process, as suggested before, is more fundamental even than Generation—or it is a process of which Generation is only one department.

Regeneration is the key to the meaning of love—to be in the first place born again in some one else or through some one else; in the second place only, to be born again through a child. As in the Protozoa, so among human beings, generation alone can hardly be looked upon as the primary object of conjugation; for, among the latter, out of myriads of unions vast numbers are as a matter of fact infertile, and a considerable percentage (as indicated above) are quite necessarily infertile, and yet these infertile unions are quite as close, and the love concerned in them quite as intense and penetrating, as in the case of the fertile ones. “If a girl were free to choose according to her inclinations,” says Florence Farr in an eloquent plea for the economic independence of women,[[31]] “there is practically no doubt that she would choose the right father for her child, however badly she might choose a life-long companion for herself.” In this passage the authoress seems to suggest (perhaps following Schopenhauer) that the generation of a perfect child is the one main even though unconscious purpose of love-union, and that the individual parent-lives may instinctively be sacrificed for this object. And there no doubt is so far truth in this, that the tremendous forces of love often pay little respect to the world conveniences and compatibilities of the lovers themselves, and that often (as indeed also among the Protozoa) the parent’s life is rudely and ruthlessly sacrificed for the birth of the next generation. Still, even so, I think the statement as put here is risky, both as a matter of fact and as a matter of theory. Would it not be more correct or less risky to say: “If a girl were free to choose, she would choose the man who most completely compensated and rounded out her own qualities, physical and mental (and so would be likely to get her a fine babe), even though he might not prove the best of companions?”

It is curious, as we have suggested before, how married folk often quarrel to desperation on the surface, and yet seem to have a deep and permanent hold on each other—returning together again even after separation. It seems in these cases as if they mutually obtained a stimulus from each other, even by their strife, which they could not get elsewhere. Iræ amantium redintegratio amoris. The idea, too, that the great and primal object of union is to be sought in the next generation has something unsatisfactory about it. Why not in this generation? Why should the blessedness of mankind always be deferred to posterity? It is not merely, I take it, the perpetuation of the race which is the purpose of love, but the perfection of the race, the completeness and adequacy of its self-expression, which love may make possible to-day just as well as to-morrow. Ellen Key, in that fine book, Liebe und Ehe,[[32]] expresses this well when she says: “Love seeks union, not only in connection with the creation of a new being, but also because two beings through one another may become a new being, and a greater than either could be of itself alone.”

The complementary nature of sex-attraction was made much of by that youthful genius Otto Weininger, who in his book, Sex and Character,[[33]] has a chapter on the laws of Sexual Attractions in which, in the true German manner, he not only gives an algebraic formula for the different types of men and women, but a formula also for the force of attraction between any two given individuals—which latter of course becomes infinite when the two individuals are exactly complementary to each other! Dr. Magnus Hirschfeld, in his very interesting work, Die Transvestiten,[[34]] goes even more into detail than does Weininger on the subject of the variations of human type in special regard to sex-characteristics. Sex-characteristics, he explains, may be divided into four groups, of which two are physiological, namely the primary characteristics (the sex organs and adjuncts) and the secondary (the hair, the voice, the breasts, and so forth); and two are psychological or related (like love-sentiment, mental habit, dress, and so forth). Each of the four groups includes about four different elements; so that altogether he tabulates sixteen elements in the human being—each of which may vary independently of the other fifteen, and take on at least three possible forms, either distinctly masculine, distinctly feminine, or intermediate. Calculating up the number of different types which these variations would thus give rise to, he arrives at the figure 43,046,721!—which figure, I think we may say, we need not analyze further, since it is certainly quite large enough for all practical purposes! And really though we may mock a little at these fanciful divisions and dissections of human nature, they do help us to realize the enormous, the astounding number of varieties of which it is susceptible. And if again we consider that among the supposed forty-three millions each variety would have its counter type or complementary individual, then we realize the enormous number of perfect unions which would be theoretically possible, and the enormous number of distinct and different ways in which the race-life could thus find adequate and admirable expression for itself.

However, we are here getting into a somewhat abstract region. To return to the practical, the complementary idea certainly seems to account for much of human union; for though there are but few cases in which the qualities of the uniting parties are really quite complementary to each other, yet it is obvious that each person tends to seek and admire attributes in the other which he himself possesses only in small degree. At the same time, it must not be forgotten that some common qualities and common ground are necessary as a basis for affection, and that sympathy and agreement in like interests and habits are at least as powerful a bond as admiration of opposites. It sometimes happens that there are immense romances between people of quite different classes and habits of life, or of quite different race and color; and they see, for the moment, flaming ideals and wonder-worlds in each other. But unions in such cases are doubtful and dangerous, because so often the common ground of sympathy and mutual understanding will be too limited; and hereditary instincts and influences, deep-lying and deep-working, will call the wanderers away, even from the star which they seek to follow.

Sympathy with and understanding of the person one lives with must be cultivated to the last degree possible, because it is a condition of any real and permanent alliance. And it may even go so far (and should go so far) as a frank understanding and tolerance of such person’s other loves. After all, it seldom happens, with any one who has more than one or two great interests in life, that he finds a mate who can sympathize with or understand them all. In that case a certain portion of his personality is left out in the cold, as it were; and if this is an important portion it seems perfectly natural for him to seek for a mate or a lover on that side too. Two such loves are often perfectly compatible and reconcilable—though naturally one will be the dominant love, and the other subsidiary, and if such secondary loves are good-humoredly tolerated and admitted, the effect will generally be to confirm the first and original alliance all the more.

All this, however, does not mean that a man can well be ‘in love’ with two women, for instance, at the same time. To love is a very different thing from being ‘in love’; and the latter indicates a torrent-rush of feeling which necessarily can only move towards one person at a time. (A standing flood of water may embrace and surround several islands, but it cannot very well flow in more than one direction at once.) But this torrent-rush does not last forever, and in due time it subsides into the quiescent and lake-like stage—unless indeed it runs itself out and disappears altogether.
