On the downhill road they go faster, and eat lighter, and the dust of their going is a great cloud behind them.

They come to the cities — there are nine of them; Terke Keter is the largest — standing full of sand and silence and sunlight. They pour in through the gates and doors, they fill the streets, they light the lanterns, they draw water from the brimming wells, they throw their bedding down in empty rooms, they shout from window to window and from roof to roof.

Life in the cities is so different from life in the homesteads that the children can't believe it; they are disturbed and dubious; they disapprove. It is so noisy, they complain. It's hot. There isn't anywhere to be alone, they say. They weep, the first nights, from homesickness. But they go off to school as soon as the schools are organised, and there they meet everybody else their age, all of them disturbed and dubious and disapproving and shy and eager and wild with excitement. Back home, they all learned to read and write and do arithmetic, just as they learned carpentry and farming, taught by their parents; but here are advanced classes, libraries, museums, galleries of art, concerts of music, teachers of art, of literature, of mathematics, of astronomy, of architecture, of philosophy — here are sports of all kinds, games, gymnastics, and somewhere in the city every night there is a round dance — above all, here is everybody else in the world, all crowded into these yellow walls, all meeting and talking and working and thinking together in an endless ferment of mind and occupation.

The parents seldom stay together in the cities. Life there is not lived by twos, but in groups. They drift apart, following friends, pursuits, professions, and see each other now and then. The children stay at first with one parent or the other, but after a while they too want to be on their own and go off to live in one of the warrens of young people, the communal houses, the dormitories of the colleges. Young men and women live together, as do grown men and women. Gender is not of much import where there is no sexuality.

For they do everything under the sun in the Cities Under the Sun, except make love.

They love, they hate, they learn, they make, they think hard, work hard, play; they enjoy passionately and suffer desperately, they live a full and human life, and they never give a thought to sex — unless, as Kergemmeg said with a perfect poker face, they are philosophers.

Their achievements, their monuments as a people, are all in the Cities under the Sun, whose towers and public buildings, as I saw in a book of drawings Kergemmeg showed me, vary from stern purity to fervent magnificence. Their books are written there, their thought and religion took form there over the centuries. Their history, their continuity as a culture, is all there.

Their continuity as living beings is what they see to in the North.

Kergemmeg said that while they are in the South they do not miss their sexuality at all. I had to take him at his word, which was given, hard as it might be for us to imagine, simply as a statement of fact.

And as I try to tell here what he told me, it seems wrong to describe their life in the cities as celibate or chaste: for those words imply a forced or willed resistance to desire. Where there is no desire there is no resistance, no abstinence, but rather what one might call, in a radical sense of the word, innocence. They don't think about sex, they don't miss it, it is a non-problem. Their marital life is an empty memory to them, meaningless. If a couple stays together or meets often in the South it is because they are uncommonly good friends — because they love each other. But they love their other friends too. They never live separately from other people. There is little privacy in the great apartment houses of the cities — nobody cares about it. Life there is communal, active, sociable, gregarious, and full of pleasures.

But slowly the days grow warmer; the air dryer; there is a restlessness in the air. The shadows begin to fall differently. And the crowds gather in the streets to hear the Year Priests announce the solstice and watch the sun stop, and pause, and turn south.

People leave the cities, one here, a couple there, a family there… It has begun to stir again, that soft hormonal buzz in the blood, that first vague yearning intimation or memory, the body's knowledge of its kingdom coming.

The young people follow that knowledge blindly, without knowing they know it. The married couples are drawn back together by all their wakened memories, intensely sweet. To go home, to go home and be there together!

All they learned and did all those thousands of days and nights in the cities is left behind them, packed up, put away. Till they come back South again…

"That is why it was easy to turn us aside," Kergemmeg said. " Because our lives in the North and the South are so different that they seem, to you others, incoherent, incomplete. And we cannot connect them rationally. We cannot explain or justify our Madan to those who live only one kind of life. When the Bayderac came to our plane, they told us our Way was mere instinct and that we lived like animals. We were ashamed."

(I later checked Kergemmeg's "Bayderac" in the Encyclopedia Planaria, where I found an entry for the Beidr, of the Unon Plane, an aggressive and enterprising people with highly advanced material technologies, who have been in trouble more than once with the Interplanary Agency for interfering on other planes. The tourist guidebook gives them the symbols that mean "of special interest to engineers, computer programmers, and systems analysts.")

Kergemmeg spoke of them with a kind of pain. It changed his voice, tightened it. He had been a child when they arrived — the first visitors, as it happened, from another plane. He had thought about them the rest of his life.

"They told us we should take control over our lives. We should not live two separate half- lives, but live fully all the time, all the year, as all intelligent beings did. They were a great people, full of knowledge, with high sciences and great ease and luxury of life. To them we truly were little more than animals. They told us and showed us how other people lived on other planes. We saw we were foolish to do without the pleasure of sex for half our life. We saw we were foolish to spend so much time and energy going between South and North on foot, when we could make ships, or roads and cars, or airplanes, and go back and forth a hundred times a year if we liked. We saw we could build cities in the North and make homesteads in the South. Why not? Our Madan was wasteful and irrational, a mere animal impulse controlling us. All we had to do to be free of it was take the medicines the Bayderac gave us. And our children need not take medicines, but could have their being altered by the genetic science of Bayder. Then we could be without rest from sexual desire until we got very old, like the Bayderac. And then a woman would be able to get pregnant at any time before her menopause — in the South, even. And the number of her children would not be limited… They were eager to give us these medicines. We knew their doctors were wise. As soon as they came to us they had given us treatments for some of our illnesses, that cured people as if by a miracle. They knew so much. We saw them fly about in their airplanes, and envied them, and were ashamed.

"They brought machines for us. We tried to drive the cars they gave us on our narrow, rocky roads. They sent engineers to direct us, and we began to build a huge Highway straight through the Middle Land. We blew up mountains with the explosives the Bayderac gave us so the Highway could run wide and level, south to north and north to south. My father was a workman on the Highway. There were thousands of men working on that road, for a while. Men from the southern homesteads… Only men. Women were not asked to go and do that work. Bayder women did not do such work. It was not women's work, they told us. Women were to stay home with the children while men did the work."
