The intelligence, emotions, and desires of the human infant at birth differ not at all perceptibly, as its sex may be male or female; and such psychic differences as appear to exist in later childhood are undoubtedly very largely the result of artificial training, forcing on the appearance of psychic sexual divergencies long before they would tend spontaneously to appear; as where sports and occupations are interdicted to young children on the ground of their supposed sexual unfitness; as when an infant female is forcibly prevented from climbing or shouting, and the infant male from amusing himself with needle and thread or dolls.

Even in the fully adult human, and in spite of differences of training, the psychic activities over a large extent of life appear to be absolutely identical.

The male and female brains acquire languages, solve mathematical problems, and master scientific detail in a manner wholly indistinguishable: as illustrated by the fact that in modern universities the papers sent in by male and female candidates are as a rule absolutely identical in type.

Placed in like external conditions, their tastes and emotions, over a vast part of the surface of life, are identical; and, in an immense number of those cases where psychic sex differences appear to exist, subject to rigid analysis they are found to be purely artificial creations, for, when other races or classes are studied, they are found non-existent as sexual characteristics; as when the female is supposed by ignorant persons in modern European societies to have an inherent love for bright colours and ornaments, not shared by the male; while experience of other societies and past social conditions prove that it is as often the male who has been even more desirous of attiring himself in bright raiment and adorning himself with brilliant jewels; or as when, among certain tribes of savages, the use of tobacco is supposed to be a peculiarly female prerogative, while, in some modern societies, it is supposed to have some relation to masculinity.

(The savage male of today when attired in his paint, feathers, cats' tails and necklaces is an immeasurably more ornamented and imposing figure than his female, even when fully attired for a dance in beads and bangles: the Oriental male has sometimes scarcely been able to walk under the weight of his ornaments; and the males of Europe a couple of centuries ago, with their powdered wigs, lace ruffles and cuffs, paste buckles, feathered cocked hats, and patches were quite as ridiculous in their excess of adornment as the complementary females of their own day, or the most parasitic females of this.
