In the animal world all forms of psychic variations are found allying themselves now with the male sex form, and then with the female. In the insect and fish worlds, where the female forms are generally larger and stronger than the male, the female is generally more pugnacious and predatory than the male. Among birds-of-prey, where also the female form is larger and stronger than the male, the psychic differences seem very small. Among eagles and other allied forms, which are strictly monogamous, the affection of the female for the male is so great that she is said never to mate again if the male dies, and both watch over and care for the young with extreme solicitude. The ostrich male form, though perhaps larger than the female, shares with her the labour of hatching the eggs, relieving the hen of her duty at a fixed hour daily: and his care for the young when hatched is as tender as hers. Among song-birds, in which the male and female forms are so alike as sometimes to be indistinguishable, and which are also monogamous, the male and female forms not only exhibit the same passionate affection for each other (in the case of the South African cock-o-veet, they have one answering love-song between them; the male sounding two or three notes and the female completing it with two or three more), but they build the nest together and rear the young with an equal devotion. In the case of the little kapok bird of the Cape, a beautiful, white, fluffy round nest is made by both out of the white down of a certain plant, and immediately below the entrance to the cavity in which the little female sits on the eggs is a small shelf or basket, in which the tiny male sits to watch over and guard them. It is among certain orders of birds that sex manifestations appear to assume their most harmonious and poetical forms on earth. Among gallinaceous birds, on the other hand, where the cock is much larger and more pugnacious than the female, and which are polygamous, the cock does not court the female by song, but seizes her by force, and shows little or no interest in his offspring, neither sharing in the brooding nor feeding the young; and even at times seizing any tempting morsel which the young or the hen may have discovered.

Among mammals the male form tends to be slightly larger than the female, though not always (the female whale, for instance, being larger than the male); the male also tends to be more pugnacious and less careful of the young; though to this rule also there are exceptions. In the case of the South African mierkat, for instance, the female is generally more combative and more difficult to tame than the male; and it is the males who from the moment of birth watch over the young with the most passionate and tender solicitude, keeping them warm under their persons, carrying them to places of safety in their mouths, and feeding them till full grown; and this they do not only for their own young, but to any young who may be brought in contact with them. We have known a male mierkat so assiduous in feeding young that were quite unrelated to himself, taking to them every morsel of food given him, that we have been compelled to shut him up in a room alone when feeding him, to prevent his starving himself to death: the male mierkat thus exhibiting exactly those psychic qualities which are generally regarded as peculiarly feminine; the females, on the other hand, being far more pugnacious towards each other than are the males.

Among mammals generally, except the tendency to greater pugnacity shown by the male towards other males, and the greater solicitude for the young shown generally by the female form, but not always; the psychic differences between the two sex forms are not great. Between the male and female pointer as puppies, there is as little difference in mental activity as in physical; and even when adult, on the hunting ground, that great non-sexual field in which their highest mental and physical activities are displayed, there is little or nothing which distinguishes materially between the male and female; in method, manner, and quickness they are alike; in devotion to man, they are psychically identical. (It is often said the female dog is more intelligent than the male; but I am almost inclined to doubt this, after long and close study of both forms.) It is at the moment when the reproductive element comes fully into play that similarity and identity cease. In the intensity of initial sex instinct they are alike; the female will leap from windows, climb walls, and almost endanger her life to reach the male who waits for her, as readily as he will to gain her. It is when the bitch lies with her six young drawing life from her breast, and gazing with wistful and anguished solicitude at every hand stretched out to touch them, a world of emotion concentrated on the sightless creatures, and a whole body of new mental aptitudes brought into play in caring for them, it is then that between her and the male who begot them, but cares nothing for them, there does rise a psychic difference that is real and wide. Alike in the sports of puppydom and the non-sexual activities of adult age; alike in the possession of the initial sexual instinct which draws the sex to the sex, the moment active sexual reproduction is concerned, there is opened to the female a certain world of sensations and experiences, from which her male companion is for ever excluded.

So also is our human world: alike in the sports, and joys, and sorrows of infancy; alike in the non-sexual labours of life; alike even in the possession of that initial instinct which draws sex to sex, and which, differing slightly in its forms of manifestation is of corresponding intensity in both; the moment actual reproduction begins to take place, the man and the woman enter spheres of sensation, perception, emotion, desire, and knowledge which are not, and cannot be, absolutely identical. Between the man who, in an instant of light-hearted enjoyment, begets the infant (who may even beget it in a state of half-drunken unconsciousness, and may easily know nothing of its existence for months or years after it is born, or never at all; and who under no circumstances can have any direct sensational knowledge of its relation to himself) and the woman who bears it continuously for months within her body, and who gives birth to it in pain, and who, if it is to live, is compelled, or was in primitive times, to nourish it for months from the blood of her own being—between these, there exists of necessity, towards a limited but all-important body of human interests and phenomena, a certain distinct psychic attitude. At this one point, the two great halves of humanity stand confronting certain great elements in human existence, from angles that are not identical. From the moment the universal initial attraction of sex to sex becomes incarnate in the first concrete sexual act till the developed offspring attains maturity, no step in the reproductive journey, or in their relation to their offspring, has been quite identical for the man and the woman. And this divergence of experiences in human relations must react on their attitude towards that particular body of human concerns which directly is connected with the sexual reproduction of the race; and, it is exactly in these fields of human activity, where sex as sex is concerned, that woman as woman has a part to play which she cannot resign into the hands of others.

It may be truly said that in the laboratory, the designing-room, the factory, the mart, the mathematician’s study, and in all fields of purely abstract or impersonal labour, while the entrance of woman would add to the net result of human labour in those fields, and though a grave injustice is done to the individual woman excluded from perhaps the only field she is fitted to excel in, that yet woman as woman has probably little or nothing to contribute in those fields that is radically distinct from that which man might supply; there would be a difference in quantity but probably none in kind, in the work done for the race.

But in those spheres of social activity, dealing especially with certain relations between human creatures because of their diverse if complementary relation to the production of human life, the sexes as sexes have often each a part to play which the other cannot play for them; have each a knowledge gained from phases of human experience, which the other cannot supply; here woman as woman has something radically distinct to contribute to the sum-total of human knowledge, and her activity is of importance, not merely individually, but collectively, and as a class.

That demand, which today in all democratic self-governing countries is being made by women, to be accorded their share in the electoral, and ultimately in the legislative and executive duties of government, is based on two grounds: the wider, and more important, that they find nothing in the nature of their sex-function which exonerates them, as human beings, from their obligation to take part in the labours of guidance and government in their state: the narrower, but yet important ground, that, in as far as in one direction, i.e., in the special form of their sex function takes, they do differ from the male, they, in so far, form a class and are bound to represent the interests of, and to give the state the benefit of, the insight of their class, in certain directions.

Those persons who imagine that the balance of great political parties in almost any society would be seriously changed by the admission of its women in public functions are undoubtedly wholly wrong. The fundamental division of humans into those inclined to hold by the past and defend whatever is, and those hopeful of the future and inclined to introduce change, would probably be found to exist in much the same proportion were the males or the females of any given society compared: and the males and females of each class will in the main share the faults, the virtues, and the prejudices of their class. The individuals may lose by being excluded on the ground of sex from a share of public labour, and by being robbed of a portion of their lawful individual weight in their own society; and the society as a whole may lose by having a smaller number to select its chosen labourers from; yet, undoubtedly, on the mass of social, political, and international questions, the conclusions arrived at by one sex would be exactly those arrived at by the other.

Were a body of humans elected to adjudicate upon Greek accents, or to pass a decision on the relative fineness of woollens and linens, the form of sex of the persons composing it would probably have no bearing on the result; there is no rational ground for supposing that, on a question of Greek accents or the thickness of cloths, equally instructed males and females would differ. Here sex plays no part. The experience and instructedness of the individuals would tell: their sexual attributes would be indifferent.

But there are points, comparatively small, even very small, in number, yet of vital importance to human life, in which sex does play a part.
