What, in the most elemental form, is sex? It is a difference of function which makes it necessary for two organisms to take part in the reproduction of the species. The purpose, or at any rate the effect, of this sex difference is the mixing of characteristics and qualities. If the sex relationship were unnecessary to reproduction, variations might begin, and be propagated and carried to extremes in one line of inheritance, without ever affecting the rest of the species. Very soon there would be no species, or rather an infinity of them; each line of descent would fly apart, and become a group all by itself. You have perhaps heard people comment on the fact that blondes so frequently prefer brunettes, and that tall men are apt to marry short women, and vice versa. This is perhaps nature's way of keeping the type uniform, of spreading qualities widely and testing them thoroughly. Nature is continually trying out the powers of every individual in every species, and by the process of sexual selection she chooses, for the reproduction of the species, the individuals which are best fitted for survival. This, of course, refers to nature, considered apart from man. In human society, as I shall presently show, sexual selection has been distorted, and partly suppressed.

Sex differentiation and sexual selection exist almost universally throughout the animal and vegetable kingdoms, everywhere save in the lowest forms of being. They take strange and startling forms, and like everything else in nature manifest amazing ingenuity. People who wish to prove this or that about human sex relations will advance arguments from nature; but as a matter of fact we can learn nothing whatever from nature, except her determination to preserve the products of her activity and to keep them up to standard. Sometimes nature will give the precedence in power, speed and beauty to the male, and sometimes to the female. She is perfectly ruthless, and willing in the accomplishment of her purpose to destroy the individuals of either sex. She will content the most rabid feminist by causing the female spider to devour her mate when his purpose has been accomplished; or by causing the male bee to fall from his mating in the air, a disemboweled shell.

As for man, he has won his supremacy over nature by his greater power to combine in groups; by his more intense gregarious, or herd instincts, which enabled him to fight and destroy creatures which would have exterminated him if he had fought them alone. So in primitive society everywhere, we find that the individual is subordinated to the group, and the "folkways" give but little heed to personal rights. Very thorough investigations have been made into the life of primitive man in many parts of the world, and the anthropologists are now arguing over the exact meaning of the data. We shall not here attempt to decide among them, but rest content with the statement that communism and tribal ownership is a widespread social form among primitive man, so much so as to suggest that it is an early stage in social evolution.

And this communism includes, not merely property, but sex. In the very earliest days there was often no barrier whatever to the sex relationship; not even between brothers and sisters, nor between parents and children. In fact, we find savages who do not know that the sex relationship has anything to do with procreation. But as knowledge increases, sex "tabus" develop, some wise, and some foolish. From causes not entirely clear, but which we discuss in Chapter XLVIII, there gradually evolves a widespread form of sex relationship of primitive man, the system of the "gens," as it is called. This is the Latin word for family, but it does not mean family in the narrow sense of mother and father and children, but in the broad sense of all those who have blood relationship, however far removed—uncles and aunts and cousins, as far as memory can trace. In primitive communism a man is not permitted to enter into the sex relationship with a woman of the same gens, but with all the women of some other gens. It is difficult for us to imagine a society in which all the men named Jones would be married to all the women named Smith; but that was the way whole races of mankind lived for many thousands of years.

In that primitive communist society, the woman was generally the equal of the man. It is true that she did the drudgery of the camp, but the man, on the other hand, faced the hardships of battle and the chase on land and sea. The woman was as big as the man, and except when handicapped by pregnancy, as strong as the man; she was as much respected, if not more so. Her children bore her name, and were under her control, and she was accustomed to assert herself in all affairs of the tribe. In Frederick O'Brien's "White Shadows in the South Seas," you may read a comical story of a journey this traveler made into the interior of one of the cannibal islands. Everywhere he was treated with courtesy and hospitality, but was embarrassed by continual offers from would-be wives. In one case a powerful cannibal lady, whose advances he rejected, picked him up and proceeded to carry him off, and he was quite helpless in her grasp; he might have been a cannibal husband today, if it had not been for the intervention of his fellow travelers.

The basis of this sex equality under primitive communism is easy to understand. All goods belonged to the tribe, and were shared alike according to need. Children were the tribe's most precious possession; therefore the woman suffered little handicap from having a child to bear and feed. Primitive woman would bear her child by the roadside, and pick it up in her arms, and continue her journey; and when she needed food, she did not have to beg for it—if there was food for anyone, there was food for her and her child. She did her share of the gathering and preparing of food, because that was the habit and law of her being; she had energies, and had never heard of the idea of not using them.

This primitive communism generally disappears as the tribe progresses. We cannot be sure of all the stages of its disappearance, or of the causes, but in a general way we can say that it gives way before the spread of slavery. In the beginning primitive man does not have any slaves, he does not have sufficient foresight or self-restraint for that. When he kills his enemies in battle, he builds a fire and roasts their flesh and eats them; and those whom he captures alive, he binds fast and takes with him, to be sacrificed to his voodoo gods. But as he comes to more settled ways of living, and as the tribe grows larger, it occurs to the chiefs in battle that the captives would be glad to give their labor in return for their lives, and that it would be convenient to have some people to do the hard and dirty work. So gradually there comes to be a class at the bottom of society, and another class at the top. Those who capture the slaves and keep them at work lay claim to the products of their labor—at first better weapons and personal adornments, then separate homes for the chiefs and priests, separate gardens, separate flocks and herds, and—what more natural?—separate women.

This process becomes complete when the tribe settles down to agriculture, and the ruling classes take possession of the land. When once the land is privately owned, classes are fixed, and class distinctions become the most prominent fact in society. And step by step as this happens, we see women beaten down, from the position of the cannibal lady, who could ask for the man she wanted and carry him off by force if necessary, to the position of the modern woman, who is physically weak, emotionally unstable, economically dependent, and socially repressed. You may resent such phrases, but all you have to do is to read the laws of civilized countries, written into the statute books by men to define the rights and duties of women; you will see that everywhere, before the recent feminist revolt, women were classified under the law with children and imbeciles.

Maternity imposes on woman a heavy burden, and before the discovery of birth control, a burden that is continuous. For nine months she carries the child in her body, and then for a year or two she carries it in her arms, or on her back; and by that time there is another child, and this continues until she is broken down. Having this burden, she cannot possibly compete with the unburdened male for the possession of property. So wherever there is economic competition; wherever certain individuals or classes in the tribe or group are allowed to seize and hold the land; wherever the products of labor cease to be the community property, and become private property, the objects of economic strife; then inevitably and by natural process, woman comes to be placed among those who cannot protect themselves—that is, among the children and the imbeciles and the slaves. Of course, some children are well cared for, and so are some imbeciles, and some slaves, and some women. But they are cared for as a matter of favor, not as a matter of their own power. They proceed no longer as the cannibal lady, but by adopting and cultivating the slave virtues, by making themselves agreeable to their masters, by flattering their masters' vanity and sensuality—in other words by exercising what we are accustomed to call "feminine charm."

From early barbaric society up to the present day, we observe that there are classes of women, just as there are classes of men. The position of these classes changes within certain limits, but in broad outline the conditions are fixed, and may be easily defined. There is, first of all, the ruling class woman. She must have birth; she may or may not have wealth, according as to whether the laws of that society or tribe permit her to have possessions of her own, or to inherit anything from her parents. If she has no wealth, then she will need beauty. She is the woman who is selected by the ruling class man to bear his name and his children, and to have charge of the household where these children are reared, and trained for the inheriting of their father's wealth and the carrying on of his position. This confers upon the ruling class woman great dignity, and makes her a person of responsibility. She rules, not merely over the slaves of the household, but over men of inferior social classes, and in a few cases an exceptionally able woman has become a queen, and ruled over men of her own class. This ruling class woman has been known through all the ages by a special name, and the ways and customs regarding her have been studied in an entertaining book, "The Lady," by Emily James Putnam.

Next in privilege and position to the "lady" is the mistress, the woman who is selected by the ruling class man, not primarily to bear his children, but to entertain and divert him. She may, of course, bear children also. In barbaric societies, and up to quite recent times, the importance of the ruling class man was indicated by the number of concubines he had, and the position of these women was hardly inferior to that of the wife or queen. In the days of the French monarchy, the king's mistress was frequently more important than the queen; she was a woman of ability, maintaining her supremacy in the intrigues of the court. In ancient Greek society, the "hetairae" were a recognized class, and Aspasia, the mistress of Pericles, was the most brilliant and most conspicuous woman in Athens. In modern France, the position of the mistress is recognized by the phrase "demi-monde," or half-world. The American plutocracy has developed upon a superstructure of Puritanism, and therefore, in America, hypocrisy is necessary. But in the great cities of America, the vast majority of the ruling class men keep mistresses before marriage, and a great many keep them afterwards; and these mistresses are coming to be more and more openly flaunted, and to acquire more and more of what is called "social position." It is possible now in the "smart set" for a lady to accept the status of mistress, delicately veiled, without losing caste thereby, and actresses and other free lance women who got their start in life by taking the position of mistress, are coming more and more to be recognized as "ladies," and to be received into what are called the "best circles."

There remains to be considered the position of the lower class women. In barbarous society these women were very little different from slaves. They had no rights of their own, except such rights as their master man chose to allow them for his own convenience. They were sold in marriage by their parents, and they went where they were sold, and obeyed their new master. They became his household drudges, and reserved their affections for him; if they failed to do this, he stoned them to death, or strangled them with a cord and tied them in a sack and threw them into the river.

And, of course, the rights of the master man yielded to the rights of men of higher classes. The king or nobleman could take any woman he wished at any time, and he made laws to this effect and enforced them. In feudal society the lord of the manor claimed the right of the first night with the wives of his serfs; this was one of the ruling class privileges which was abolished in the French revolution. Wherever the French revolution did not succeed in affecting land tenure, the right of the land owner to prey upon his tenant girls continues as a custom, even though it is not written in the law, and would be denied by the hypocritical. It prevails in Poland, as you may discover by reading Sienkiewicz's "Whirlpools"; it prevails in England, as you may discover from Hardy's "Tess of the d'Urbervilles." You will find that it prevails in every part of the world where women have poverty and men have wealth and prestige, dress suits and automobiles. You will find it wherever there are leisure class hotels, or colleges, or other gatherings of ruling class young males. You will find it in the theatrical and moving picture worlds. It is well understood in the theatrical world of Broadway that the woman "star" in the profession gets her start in life by becoming the mistress of a manager or "angel." In the moving picture world of Southern California it is a recognized convention, known to everyone familiar with the business, that a young girl parts with her virtue in exchange for an important job.
