  Alvin," began eriston, "it is just twenty years since your mother and i first met you. You know what that means. Our guardianship is now ended, and you are free to do as you please." there was a trace--but merely a trace--of sadness in brixton's voice. There was considerably more relief, as if eriston was glad that a state of affairs that had existed for some time in fact now had legal recognition. Alvin had anticipated his freedom by a good many years. "I understand," he answered. "I thank you for watching over me, and i will remember you in all my lives." that was the formal response; he had heard it so often that all meaning had been leached away from it-it was merely a pattern of sounds with no particular significance. Yet "all my lives" was a strange expression, when one stopped to consider it. He knew vaguely what it meant; now the time had come for him to know exactly. There were many things in diaspar which he did not understand, and which he would have to learn in the centuries that lay ahead of him. For a moment it seemed as if etania wished to speak. She raised one hand, disturbing the iridescent gossamer of her gown, then let it fall back to her side. Then she turned helplessly to jeserac, and for the first time alvin realized that his parents were worried. His memory swiftly scanned the events of the past few weeks. No, there was nothing in his recent life that could have caused this faint uncertainty, this air of mild alarm that seemed to surround both eriston and etania. Jeserac, however, appeared to be in command of the situation. He gave an inquiring look at eriston and etania, satisfied himself that they had nothing more to say, and launched forth on the dissertation he had waited many years to make. "Alvin," he began, "for twenty years you have been my pupil, and i have done my best to teach you the ways of the city, and to lead you to the heritage which is yours. You have asked me many questions, and not all of them have i been able to answer. Some things you were not ready to learn, and some i did not know myself. Now your infancy is over, though your childhood is scarcely begun. It is still my duty to guide you, if you need my help. In two hundred years, alvin , you may begin to know something of this city and a little of its history. Even i, who am nearing the end of this life, have seen less than a quarter of diaspar, and perhaps less than a thousandth of its treasures." there was nothing so far that alvin did not know, but there was no way of hurrying jeserac. The old man looked steadfastly at him across the gulf of centuries, his words weighed down with the uncomputable wisdom acquired during a long lifetime's contact with men and machines. "Tell me, alvin," he said, "have you ever asked yourself where you were before you were born-before you found yourself facing etania and eriston at the hall of creation?" "i assumed i was nowhere-that i was nothing but a pattern in the mind of the city, waiting to be created-like this." a low couch glimmered and thickened into reality beside alvin. He sat down upon it and waited for jeserac to continue.

  "You are correct, of course," came the reply. "But that is merely part of the answer-and a very small part indeed. Until now, you have met only children of your own age, and they have been ignorant of the truth. Soon they will remember, but you will not, so we must prepare you to face the facts. For over a billion years, alvin, the human race has lived in this city. Since the galactic empire fell, and the invaders. Went back to the stars, this has been our world. Outside the walls of diaspar, there is nothing except the desert of which our legends speak. "We know little about our primitive ancestors, except that they were very short-lived beings and that, strange though it seems, they could reproduce themselves without the aid of memory units or matter organizers. In a complex and apparently uncontrollable process, the key patterns of each human being were preserved in microscopic cell structures actually created inside the body. If you are interested, the biologists can tell you more about it, but the method is of no great importance since it was abandoned at the dawn of history. "A human being, like any other object, is defined by its structure-its pattern. The pattern of a man, and still more the pattern which specifies a man's mind, is incredibly complex. Yet nature was able to pack that pattern into a tiny cell, too small for the eye to see. "What nature can do, man can do also, in his own way." we do not know how long the task took. A million years, perhaps-but what is that? In the end our ancestors learned how to analyze and store the information that would define any specific human being-and to use that information to re-create the original, as you have just created that couch. "I know that such things interest you, alvin, but i cannot tell you exactly how it is done. The way in which information is stored is of no importance; all that matters is the information itself. It may be in the form of written words on paper, n of varying magnetic fields, or patterns of electric charge. Men a have used all these methods of storage, and many others. Suffice to say that long ago they were able to store themselvesor, to be more precise, the disembodied patterns from which they could be called back into existence. "So much, you already know. This is the way our ancestors gave us virtual immortality, yet avoided the problems raised by the abolition of death. A thousand years in one body is long enough for any man; at the end of that time, his mind is clogged with memories, and he asks only for rest-or a new beginning. In a little while, alvin, i shall prepare to leave this life. I shall go back through my memories, editing them and canceling those i do not wish to keep. Then i shall walk into the hall of creation, but through a door which you have never seen. This old body will cease to exist, and so will consciousness itself. Nothing will be left of jeserac but a galaxy of electrons frozen in the heart of a crystal. "I shall sleep, alvin, and without dreams. Then one day, perhaps a hundred thousand years from now, i shall find myself in a new body, meeting those who have been chosen to be my guardians. They will look after me as eriston and etania have guided you, for at first i will know nothing of diaspar and will have no memories of what i was before. Those memories will slowly return, at the end of my infancy, and i will build upon them as i move forward into my new cycle of existence. "That is the pattern of our lives, alvin. We have all been here many, many times before, though as the intervals of nonexistence vary according to apparently random laws this present population will never repeat itself again. The new jeserac will have new and different friends and interests, but the old jeserac-as much of him as i wish to save-will still exist. "That is not all. At any moment, alvin, only a hundredth of the citizens of diaspar live and walk its streets. The vast majority slumber in the memory banks, waiting for the signal that will call them forth onto the stage of existence once again. So we have continuity, yet change-immortality, but not stagnation. I know what you are wondering, alvin. You want to know when you will recall the memories of your earlier lives, as your companions are already doing. "There are no such memories, for you are unique. We have tried to keep this knowledge from you as long as we could, so that no shadow should lie across your childhood-though i think you must have guessed part of the truth already. We did not suspect it ourselves until five years ago, but now there is no doubt. "You alvin, are something that has happened in diaspar a handful of times since the founding of the city. Periys you have been lying dormant in the memory banks through all the ages-or perhaps you were created only twenty years ago by some random permutation. You may have been planned in the beginning by the designers of the city, or you may be a purposeless accident of our own time. "We do not know. All that we do know is this: you, alvin, alone of the human race, have never lived before. In literal truth, you are the first child to be born on earth for at least ten million years."

  Three

  When jeserac and his parents had faded from view, alvin lay for a long time trying to hold his mind empty of thought. He closed his room around him, so that no one could interrupt his trance.

  He was not sleeping; sleep was something he had never experienced, for that, belonged to a world of night and day, and here there was only day. This was the nearest he could come to that forgotten state, and though it was not really essential to him he knew that it would help compose his mind.

  He had learned little new; almost everything that jeserac had told him he had already guess
ed. But it was one thing to have guessed it, another to have had that guess confirmed beyond possibility of refutation.

  How would it affect his life, if at all? He could not be sure, and uncertainty was a novel sensation to alvin. Perhaps it would make no difference whatsoever; if he did not adjust completely to diaspar in this life, he would do so in the next -or the next.

  Even as he framed the thought, alvin's mind rejected it. Diaspar might be sufficient for the rest of humanity, but it was not enough for him. He did not doubt that one could spend a thousand lifetimes without exhausting all its wonders, or sampling all the permutations of experience it could provide. These things he could do-but if he could not do more, he would never be content.

  There was only one problem to be faced. What more was there to do?

  The unanswered question jolted him out of his reverie. He could not stay here while he was in this restless mood, and there was only one place in the city where he could find some peace of mind.

  The wall flickered partially out of existence as he stepped through to the corridor, and its polarized molecules resisted his passage like a feeble wind blowing against his face. There were, many ways in which he could be carried effortlessly to his goal, but he preferred to walk. His room was almost at the main city level, and a short passage brought him out onto a spiral ramp which led down to the street. He ignored the moving way, and kept to the narrow sidewalk-an eccentric thing to do, since he had several miles to travel. But alvin liked the exercise, for it soothed his mind. Besides, there was so much to see that it seemed a pity to race past the latest marvels of diaspar when you had eternity ahead of you. It was the custom of the city's artists-and everyone in diaspar was an artist at some time or another-to display their current productions along the side of the moving ways, so that the passers-by could admire their work. In this manner, it was usually only a few days before the entire population had critically examined any noteworthy creation, and also expressed its views upon it. The resulting verdict, recorded automatically by opinion-sampling devices which no one had ever been able to suborn or deceive and there had been enough attempts-decided the fate of the masterpiece. If there was a sufficiently affirmative vote, its matrix would go into the memory of the city so that anyone who wished, at any future date, could possess a reproduction utterly indistinguishable from the original. The less successful pieces went the way of all such works. They were either dissolved back into their original elements or ended in the homes of the artists' friends. Alvin saw only one object d'art on his journey that had any appeal to him. It was a creation of pure light, vaguely reminiscent of an unfolding flower. Slowly growing from a minute core of color, it would expand into complex spirals and curtains, then suddenly collapse and begin the cycle over again. Yet not precisely, for no two cycles were identical. Though alvin watched through a score of pulsations, each time there were subtle and indefinable differences, even though the basic pattern remained the same. He knew why he liked this piece of intangible sculpture. Its expanding rhythm gave an impression of space -even of escape. For that reason, it would probably not appeal to many of alvin's compatriots. He made a note of the artist's name and decided to call him at the earliest opportunity. All the roads both moving and stationary, came to an end when they reached the park that was the green heart of the city. Here, in a circular space over three miles across, was a memory of what earth had been in the days before the desert swallowed all but diaspar. First there was a wide belt of grass, then low trees which grew thicker and thicker as one walked forward beneath their shade. At the same time the ground sloped gently downward so that when at last one emerged from the narrow forest all sign of the city had vanished, hidden by the screen of trees. The wide stream that lay ahead of alvin was called, simply, the river. It possessed, and it needed, no other name. At intervals it was spanned by narrow bridges, and it flowed around the park in a complete, closed circle, broken by occasional lagoons. That a swiftly moving river could return upon itself after a course of less than six miles had never struck alvin as at all unusual; indeed, he would not have thought twice about the matter if at some point in its circuit the river had flowed uphill. There were far stranger things than this in diaspar.

  A dozen young people were swimming in one of the little lagoons, and alvin paused to watch them. He knew most of them by sight, if not by name, and for a moment was tempted to join in their play. Then the secret he was bearing decided him against it, and he contented himself with the role of spectator.

  Physically, there was no way of telling which of these young citizens had walked out of the hall of creation this year and which had lived in diaspar as long as alvin. Though there were considerable variations in height and weight, they had no correlation with age. People were simply born that way, and although on the average the taller the person, the greater the age, this was not a reliable rule to apply unless one was dealing in centuries.

  The face was a safer guide. Some of the newborn were taller than alvin, but they had a look of immaturity, an expression of wondering surprise at the world in which they now found themselves that revealed them at once. It was strange to think that, slumbering untapped in their minds, were infinite vistas of lives that they would soon remember. Alvin envied them, yet he was not sure if he should. One's first existence was a precious gift which would never be repeated. It was wonderful to view life for the very first time, as in the freshness of the dawn. If only there were others like him, with whom he could share his thoughts and feelingst

  Yet physically he was cast in precisely the same mold as those children playing in the water. The human body had changed not at all in the billion years since the building of diaspar, since the basic design had been eternally frozen in the memory banks of the city. It had changed, however, a good deal from its original primitive form, though most of the alterations were internal and not visible to the eye. Man had rebuilt himself many times in his long history, in the effort to abolish those ills to which the flesh was once heir.

  Such unnecessary appurtenances as nails and teeth had vanished. Hair was confined to the head; not a trace was left on the body. The feature that would most have surprised a man of the dawn ages was, perhaps, the disappearance of the navel. Its inexplicable absence would have given him much food for thought, and at first sight he would also have been baffled by the problem of distinguishing male from female. He might even have been tempted to assume that there was no longer any difference, which would have been a grave error. In the appropriate circumstances, there was no doubt about the masculinity of any male in iaspar. It was merely that his equipment was now more neatly packaged when not required; internal stowage had vastly improved upon nature's original inelegant and indeed downright hazardous arrangements.

  It was true that that reproduction was no longer the concern of the body, being far too important a matter to be left to games of chance played with chromosomes as dice. Yet, though conception and birth were not even memories, sea remained. Even in ancient times, not one-hundredth part of sexual activity had been concerned with reproduction. The disappearance of that mere one per cent had changed the pattern of human society and the meaning of such words as "father" and "mother"-but desire remained, though now its satisfaction had no profounder aim than that of any of the other pleasures of the senses. Alvin left his playful contemporaries and continued on toward the center of the park. There were faintly marked paths here, crossing and crisscrossing through low shrubbery and occasionally diving into narrow ravines between great lichencovered boulders. Once he came across a small polyhedral machine, no larger than a man's head, floating among the branches of a tree. No one knew how many varieties of robot there were in diaspar; they kept out of the way and minded their business so effectively that it was quite unusual to see one.

  Presently the ground began to rise again; alvin was approaching the little hill that was at the exact center of the park, and therefore of the city itself. There were fewer obstacles and detours, and he had a clear view to the
summit of the hill and the simple building that surmounted it. He was a little out of breath by the time he had reached his goal, and was glad to rest against one of the rose-pink columns and to look back over the way he had come.

  There are some forms of architecture that can never change because they have reached perfection. The tomb of yarlan zey might have been designed by the temple builders of the first civilizations man had ever known, though they would have found it impossible to imagine of what material it was made. The roof was open to the sky, and the single chamber was paved with great slabs which only at first sight resembled natural stone. For geological ages human feet had crossed and recrossed that floor and left no trace upon its inconceivably stubborn material.

  The creator of the great park-the builder, some said, of diaspar itself-sat with slightly downcast eyes, as if examining the plans spread across his knees. His face wore that curiously elusive expression that had baffled the world for so many generations. Some had dismissed it as no more than an idle whim of the artist's, but to others it seemed that yarlan zey was smiling at some secret jest. The whole building was an enigma, for nothing concerning it could be traced in the historical records of the city. Alvin was not even sure what the word "tomb" meant; jeserac could probably tell him, because he was fond of collecting obsolete words and sprinkling his conversation with them, to the confusion of his listeners.
