FOR US THE LIVING BY ROBERT A. HEINLEIN

“The case of female sex jealousy of the male differs greatly from that of the male. Female sex jealousy is primarily economic in origin, that of the male is primarily biological. The desire for sexual intercourse is not an important survival factor in the female. She may be impregnated without it, or even in the face of a strong contra-desire, as in rape. The dominant survival factor for the female is the need for protection and support during gestation and while caring for infant children. This will take the form of possessive sexual jealousy in any environment which requires her to capture the full attention of one man to achieve the end. It is not necessary that she be consciously aware of this. It is automatic. By and large, in such an environment, only the females who function in that pattern are able to reproduce. Many environments do not lay this requirement on the female. Yours did, to a marked degree, if the literature and records of your period are correct.

“From all I can gather the competition among women for the exclusive attention of one man must have been as fierce and ruthless as any jungle battle. It appears from history that the women of your period and before were able to freeze into law and creed that a man must take one woman and support her and her children to the exclusion of any other interest. A woman who connived with a man to break this stringent code of battle, as in adultery, was destroyed by her sisters as completely as they were able.

“Nevertheless, even in your day, the signs of environmental change and consequent changes in your ‘immutable’ human nature were in evidence so far as women were concerned. They were gaining greater economic freedom and consequent greater sexual independence. They no longer needed to the same extent the economic support of husbands. It was even possible for a woman of foresight and ability to bear and rear children without the economic support of a male. With increased knowledge and use of practical convenient methods of controlling conception women were liberated somewhat from the pressing necessity for capturing a man and holding him. With the advent of the New Economic Regime women no longer required the services of a man to support herself or her offspring. For the first time in history women reached the dignity of social equality with men. Up to that time any equality with men granted to them was spurious, a mere verbalism, having no real foundation in fact.

“The social consequences were of enormous importance both to women and to men. For the first time in history men and women could mate as equals without fear of concealed motives. Life was enormously enriched thereby. Love between the sexes could develop aesthetically in a way never before possible. Freed of the twin vices of masqued rape and masqued prostitution, it developed a beauty, a variety, and a richness limited only by the imagination and sensitivity of the individuals concerned. Not only did it glorify the love between man and woman but it made possible a deeper, less antagonistic, relation between man and his brother, woman and her sister, for the primary causes of rivalry were gone. Gone for men as well as for women. Why?

“You recall that the primary cause of sex jealousy in men was the desire for intercourse. In former cultures other men might lure away a desired woman with economic bait or capture her bodily. Now that the woman is no longer subject to coercion but is a free agent, the competition between males for a woman’s charms is necessarily by gentler means. Excesses of jealousy are likely to defeat their own ends and lose a woman completely. You are lucky that your chosen woman was sufficiently primitive in her emotion and loyal in her intellect that she decided to stick by you. Many women would have told you to go to the devil and taken up with a less selfish man.”

Perry was startled to hear himself called selfish. He started to speak, then thought better of it and held his tongue, his face a study in mixed emotions. Hedrick continued.
