Were it proved that at certain periods fewer hermaphrodite beings were produced, and at certain other periods more, it would appear that the rising and falling, the periodic occurrence and disappearance of the woman movement in an unfailing rhythm of ebb and flow, was one of the expressions of the preponderance of masculine and feminine women with the concomitant greater or lesser desire for emancipation. Obviously I do not take into account in relation to the woman question the large number of womanly women, the wives of the prolific artisan class whom economic pressure forces to factory or field labour. The connection between industrial progress and the woman question is much less close than is usually realised, especially by the Social Democratic Group. The relation between the mental energy required for intellectual and for industrial pursuits is even less. France, for instance, although it can boast three of the most famous women, has never had a successful woman’s movement, and yet in no other European country are there so many really businesslike, capable women. The struggle for the material necessities of life has nothing to do with the struggle for intellectual development, and a sharp distinction must be made between the two. The prospects of the movement for intellectual advance on the part of women are not very promising; but still less promising is another view, sometimes discussed in the same connection, the view that the human race is moving towards a complete sexual differentiation, a definite sexual dimorphism. The latter view seems to me fundamentally untenable, because in the higher groups of the animal kingdom there is no evidence for the increase of sexual dimorphism. Worms and rotifers, many birds and the mandrills amongst the apes, have more advanced sexual dimorphism than man. On the view that such an increased sexual dimorphism were to be expected, the necessity for emancipation would gradually disappear as mankind became separated into the completely male and the completely female. On the other hand, the view that there will be periodical resurrections of the woman’s movement would reduce the whole affair to ridiculous impotence, making it only an ephemeral phase in the history of mankind. A complete obliteration will be the fate of any emancipation movement which attempts to place the whole sex in a new relation to society, and to see in man its perpetual oppressor. A corps of Amazons might be formed, but as time went on the material for the corps would cease to occur. The history of the woman movement during the Renaissance and its complete disappearance contains a lesson for the advocates of women’s rights. Real intellectual freedom cannot be attained by an agitated mass; it must be fought for by the individual. Who is the enemy? What are the retarding influences? The greatest, the one enemy of the emancipation of women is woman herself. It is left to the second part of my work to prove this.
