The female, moreover, is completely occupied and content with sexual matters, whilst the male is interested in much else, in war and sport, in social affairs and feasting, in philosophy and science, in business and politics, in religion and art. I do not mean to imply that this difference has always existed, as I do not think that important. As in the case of the Jewish question, it may be said that the Jews have their present character because it has been forced upon them, and that at one time they were different. It is now impossible to prove this, and we may leave it to those who believe in the modification by the environment to accept it. The historical evidence is equivocal on the point. In the question of women, we have to take people as they exist to-day. If, however, we happen to come on attributes that could not possibly have been grafted on them from without, we may believe that such have always been with them. Of contemporary women at least one thing is certain. Apart from an exception to be noted in chap. xii., it is certain that when the female occupies herself with matters outside the interests of sex, it is for the man that she loves or by whom she wishes to be loved. She takes no real interest in the things for themselves. It may happen that a real female learns Latin; if so, it is for some such purpose as to help her son who is at school. Desire for a subject and ability for it, interest in it, and the facility for acquiring it, are usually proportional. He who has slight muscles has no desire to wield an axe; those without the faculty for mathematics do not desire to study that subject. Talent seems to be rare and feeble in the real female (although possibly it is merely that the dominant sexuality prevents its development), with the result that woman has no power of forming the combinations which, although they do not actually make the individuality, certainly shape it. Corresponding to true women, there are extremely female men who are to be found always in the apartments of the women, and who are interested in nothing but love and sexual matters. Such men, however, are not the Don Juans.
