Glory Road by Robert A. Heinlein

But I had chances to show “virtue.” That kitten with the wasp waist tempted me–and I learned that she was of a culture in which females may not marry until they prove themselves pregnable, as in parts of the South Seas and certain places in Europe; she was breaking no taboos of her tribe. I was tempted more by another gal, a sweetie with a lovely figure, a delightful sense of humor, and one of the best dancers in any universe. She didn’t write it on the sidewalk; she just let me know that she was neither too busy nor uninterested, using that argot with skillful indirection.

This was refreshing. Downright “American.” I did inquire (elsewhere) into the customs of her tribe and found that, while they were rigid as to marriage, they were permissive otherwise. I would never do as a son-in-law but the window was open even though the door was locked.

So I chickened. I gave myself a soul-searching and admitted curiosity as morbid as that of any female who propositioned me simply because I was Star’s consort. Sweet little Zhai-ee-van was one of those who didn’t wear clothes. She grew them on the spot; from tip of her nose to her tiny toes she was covered in soft, sleek, gray fur, remarkably like chinchilla. Gorgeous!

I didn’t have the heart, she was too nice a kid.

But this temptation I admitted to Star–and Star implied gently that I must have muscles between my ears; Zhai-ee-van was an outstanding artiste even among her own people, who were esteemed as most talented devotees of Eros.

I stayed chicken. A romp with a kid that sweet should involve love, some at least, and it wasn’t love, just that beautiful fur–along with a fear that a romp with Zhai-ee-van could turn into love and she couldn’t marry me even if Star turned me loose.

Or didn’t turn me loose–Center has no rule against polygamy. Some religions there have rules for and against this and that out this mixture of cultures has endless religions and they cancel each other the way conflicting customs do. Culturologists state a “law” of religious freedom which they say is invariant: Religious freedom in a cultural complex is inversely proportional to the strength of the strongest religion. This is supposed to be one case of a general invariant, that all freedoms arise from cultural conflicts because a custom which is not opposed by its negative is mandatory and always regarded as a “law of nature.”

Rufo didn’t agree; he said his colleagues stated as equations things which are not mensurate and not definable–holes in their heads! –and that freedom was never more than a happy accident because the common jerk, all human races, hates and fears all freedom, not only for his neighbors but for himself, and stamps it out whenever possible.

Back to Topic “A”–Centrists use every sort of marriage contract. Or none. They practice domestic partnership, coition, propagation, friendship, and love–but not necessarily all at once nor with the same person. Contracts could be as complex as a corporate merger, specifying duration, purposes, duties, responsibilities, number and sex of children, genetic selection methods, whether host mothers were to be hired, conditions for canceling and options for extension–anything but “marital fidelity.” It is axiomatic there that this is unenforceable and therefore not contractual.

But marital fidelity is commoner there than it is on Earth; it simply is not legislated. They have an ancient proverb reading Women and Cats. It means: “Women and Cats do as they please, and men and dogs might as well relax to it.” It has its opposite: Men and Weather which is blunter and at least as old, since the weather has long been under control.

The usual contract is no contract; he moves his clothes into her home and stays–until she dumps them outside the door. This form is highly thought of because of its stability: A woman who “tosses his shoes” has a tough time finding another man brave enough to risk her temper.

My “contract” with Star was no more than that if contracts, laws, and customs applied to the Empress, which they did not and could not. But that was not the source of my increasing unease.
