This conception of the individual as something meant to be a parent will not be questioned by anyone who will do himself or herself the justice to look at it soberly and reverently, without a trace of that tendency to levity or to something worse which here invariably betrays the vulgar mind, whether in a princess or a prostitute. For it needs little reflection to perceive that the most familiar facts of our experience and observation never fail to confirm the doctrine based by Weismann upon the revelations of the microscope when applied to the developmental processes of certain simple animal and vegetable forms. The doctrine that the individual body was evolved by the forces of life, acted on and directed by natural selection, as guardian and transmitter of the germ-plasm, assumes a less paradoxical character when we perceive with what unfailing art Nature has constructed and devised the body and the mind for their function. We flatter ourselves hugely if we suppose that even our most enjoyable and apparently most personal attributes and appetites were designed by Nature for us. Not at all. It is the race for which she is concerned. It is not the individual as individual, but the individual as potential parent, that is her concern, nor does she hesitate to leave very much to the mercy of time and chance the individual from whom the possibility of parenthood has passed away, or the individual in whom it has never appeared. Our appetites for food and drink, well devised by Nature to be pleasant in their satisfaction--lest otherwise we should fail to satisfy them and a possible parent should be lost to her purposes--are immediately rendered of no account when there stirs within us, whether in its crude or transmuted forms, the appetite for the exercise of which these others, and we ourselves, exist, since in Nature's eyes and scheme we are but vessels of the future. In later chapters we shall have much occasion, because of their great practical importance in the conduct of woman's life from girlhood onwards, to discuss the physiological and psychological facts which demonstrate overwhelmingly the truth of the view that the individual was evolved by Nature for the care of the germ-plasm, or, in other words, was and is constructed primarily and ultimately for parenthood.
