Because of the vivifying potence of her creative womanhood--the function whereof is to engender Life--the stranger admitted to her citadel becomes endued with Life, and takes up his abode with her to the end of her natural term. For this reason, the adulterous woman is adulterous in a sense impossible to man--adulterous in both a vital and an intrinsic psychical sense that is revolting. With the increasing intensification in the male, with advancing evolution, of his inherited Woman-traits, he has become ever further endowed with Woman's Sub- and Supra-conscious faculties. So that the function which was, in its primal moral, but brief and cursory, ending summarily with its biological fulfilment, has become increasingly endued in him with the vital emotionalism, and accordingly with the moral significance inherent to the Woman-nature. If his experiences fade more quickly from his consciousness than hers do, they remain nevertheless (in the degree of his psychical development) potent still in his Subconsciousness--as possibly adulterating and debasing factors. But since his Subconscious emotionalism is an acquired and not an inherent part of his male mentality, it is a medium vastly less sensitised and operative in him than it is in her; of whom it is the very basis of her being. This is no apology, of course, for masculine aberration, but a counsel of feminine virtue--a counsel making indirectly, therefore, but none the less surely for masculine virtue also. The reasons for chastity in the one sex differ diametrically from those which should be the motive thereof in the other, however. Chivalry and Prostitution are incompatible. It must be confessed, however, that deterioration of the woman-organisation and temperament conduces greatly to masculine promiscuity. Not only because this entails loss of power to charm and bind the mate, but because with the sex-immaturity, on the one hand of the over-Feminised type, on the other, of the Mannish woman, women lose, in greater or less degree, the natural power of one sex to assuage passion in the other. Man is deteriorated, moreover, by moral and psychical deterioration in that sex whence moral impulse springs, because, in such case, the appeal of woman ceases to be, as is normal, to the emotional and chivalrous in him, but evokes, on the contrary, biological instinct mainly, or merely. It is well-established truth that her first lover (or her husband, supposing she had loved him) retains a unique hold upon a woman's mind throughout her after-life--his personality or memory dominating her imagination as no later-comer is able to do. This is because that first enters into possession of both Consciousness and Subconsciousness while the tablets of these are still virgin and unblotted. This first impresses himself, therefore, clearly and strongly defined upon her exquisitely-sensitised tablets of remembrance.
