And now upsprings a further momentous consideration: Is this cause and effect? Were the sons of women in whom the potential male had remained abeyant, more virile of body and brain than are the sons of women who have cultivated masculine characteristics, solely and absolutely because the mothers in the latter case had misappropriated to their own uses powers that belonged by right of heredity to sons? While those other mothers, by retaining such in latency, preserved them as a rich inheritance for male heirs. Is it similar, indeed, to the cases of a mother who realises and expends for her own purposes her sons' financial patrimony, and of a mother who, expending the interest alone thereof, retains the capital intact; and is enabled thus to pass it on as heritage? Is the power held latent in one generation the potential of the generation following?
It may be asked: Why should woman forgo possession and exercise of faculties available to her, in order to transmit these to sons? One might answer as in respect of that other patrimony. If it be true that she holds these powers in trust merely, they are not hers to spend. To expend them is to despoil her sons; to make paupers and bankrupts of them, humanly speaking. Further, since daughters inherit from the father, the male entail woman forbears to realise and to exploit for her own uses returns to her sex in the person of her grand-daughter—by paternal inheritance. For the able father is the parent of the able daughter.
Thus Nature works with the eternal justice of eternal reciprocity between the sexes; making them all the while more complexly diverse, but nevertheless more closely interdependent. So that one sex can neither progress nor can it regress by itself; but draws the other onward with it, or drags it back. Thus, the bread of human heritage consigned to the stream of posterity by one sex, for equipment and furtherance of the other, returns to the hand of the sex that consigned it.
If this be so—and I hope to prove it so—the woman who develops the potential male in her defrauds of its lawful racial and personal entail not only the opposite sex, in the person of her son, but she defrauds of its dower her own sex too, in the person of her grand-daughter.
Of the interesting and important biological processes underlying the mystery of the Dual-Sex constitution and its manifold phenomena, I am about to present a wholly new and—I venture to believe—a wholly true and convincing elucidation.
Natura simplex est, said Newton, et sibi semper consonans. (Nature is simple and always agrees with herself.) Bewilderingly multiple in her phenomena, she is superbly simple in her principles. By the operation of her one great Law of Gravitation, she sustains the mighty Solar systems—and brings the apple to the ground. By the extension, counterpoise and co-operation of one Primal Cosmic Energy—with its dual impulses, Centripetal and Centrifugal—she has generated all the diverse marvels of a Universe. And in view of her simplicity of Principle, it is conceivable that the Duality of Sex may be an extension into Life of that same principle of Duality which characterises the vaster Cosmic phenomena.
If this be true, Man and Woman are the complex resultant of infinitely many and varied evolutionary differentiations and associations of the two modes of Primal Energy. If so, the principle of Sex must have existed before Matter; must have been inherent in Creation before Creation began to evolve. And if so, Evolution would seem to have had for its purpose the ever further and fuller manifestation of these dual and contrary inherences in terms of Life and Sex. While, to judge by effects, it has had for its means such ever more intimate and intricate co-operations of these as have resulted in the progressively diverse and complex developments found to-day in Human Life and Human Sex-Characteristics.
