(G2) Another deep objection, from the standpoint of woman, to the monogamic marriage, arises out of what is known as “maleness” in women. According to Weininger this varies in degree with each individual, and modern authorities on psychology have more or less confirmed Weininger’s view. For the reader unacquainted with the present knowledge on this point, perhaps it would be as well to state plainly what results have been obtained. In the first place it has been demonstrated to the satisfaction of most people that no one male or female is wholly masculine or feminine. The stage of hermaphroditism through which all human beings are supposed to pass in their early fœtal development, is never apparently quite overcome, and the fully developed fœtus, as also the perfectly developed child, retains in its constitution vestiges of a sex to which its outward and primary sexual characteristics do not belong. These vestiges of the other sex which survive are both physical and mental, and according to their proportion in the individual body, determine the character of their host. Thus a child who is to all outward appearance a boy may yet possess elements according to which he is actually 25 or 30 or only 10 per cent female. A female child may likewise possess vestiges of the other sex which constitute her 10, 20, 30 or even 40 per cent male. Although, therefore, all men have a preponderancy of male elements, and all women a preponderancy of female elements, each may possess a more or less heavy percentage of the elements of the other. In extreme cases these elements of the opposite sex cause trouble by leading those who possess them to form desires and to lead lives so conspicuously out of keeping with their primary sexual characteristics as to make them obnoxious to society; but it should be remembered that this degree of morbidity is rare, and that as a general rule the modicum of _maleness in the female and femaleness in the male has no such disturbing results if the other elements proper to the sex of the primary reproductive organs in each individual find their normal adaptation_. Thus the maleness in the female has a tendency to manifest itself, more especially when her sexuality is not fully developed or not actively engaged. Little girls, for instance, are notoriously sadistic—sadism being a derivative of the male reproductive instinct—as are also many spinsters and some old women. Femaleness in the male, on the other hand, tends to manifest itself particularly in cases where the male reproductive instinct has been stifled, or unhinged, or when his spirit has been ruthlessly broken. Now it may be as well for the reader to know that the attitude of the modern world is to fall down in a state of acquiescence before this important fact of sex, without attempting to inquire whether the importance with which it looms on the horizon of our lives is not precisely due to the attitude of prostrate acceptance with which it is met.
