Whereupon another seeming paradox confronts us. Namely, that the sons of those earlier women, in whom masculine inherences were permitted to remain dormant, were notably more virile of body and mind than are the sons of latter-day emancipated mothers who have sedulously cultivated and have fully exercised their male proclivities. 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.
