  Arthur C Clarke - The City and the Stars

  Preface

  For the benefit of those who have read my first novel, against the fall of night, and will recognize some of the material in the present work, a few words of explanation are in order. Against the fall of night was begun in 1937 and, after four or five drafts, was completed in 1946, though for various reasons beyond the author's control book publication was delayed until some years later. Although this work was well received, it had most of the defects of a first novel, and my initial dissatisfaction with it increased steadily over the years. Moreover, the progress of science during the two decades since the story was first conceived made many of the original ideas naive, and opened up vistas and possibilities quite unimagined when the book was originally planned. In particular, certain developments in information theory suggested revolutions in the human way of life even more profound than those which atomic energy is already introducing, and i wished to incorporate these into the book i had attempted, but so far failed, to write. A sea voyage from England to Australia gave an opportunity of getting to grips with the uncompleted job, which was finished just before i set out to the great barrier reef. The knowledge that i was to spend some months diving among sharks of doubtful docility was an additional spur to action. It may or may not be true, as doctor Johnson stated, that nothing settles a man's mind so much as the knowledge that he will be hanged in the morning, but for my part i can testify that the thought of not returning from the reef was the main reason why the book was completed at that particular time, and the ghost that had haunted me for almost twenty years was finally exorcised. About a quarter of the present work appeared in against the fall of night; it is my belief, however, that even those who read the earlier book will find that this is virtually a new novel. If not, at least i hope they will grant an author the right to have second thoughts. I promise them that this is my last word on the immortal city of Diaspora, in the long twilight of earth.

  Like a glowing jewel, the city lay upon the breast of the desert. Once it had known change and alteration, but now time passed it by. Night and day fled across the desert's face, but in the streets of Diaspora it was always afternoon, and darkness never came. The long winter nights might dust the desert with frost, as the last moisture left in the thin air of earth congealed-but the city knew neither heat nor cold. It had no contact with the outer world; it was a universe itself. Men had built cities before, but never a city such as this. Some had lasted for centuries, some for millenniums, before time had swept away even their names. Diaspora alone had challenged eternity, defending itself and all it sheltered against the slow attrition of the ages, the ravages of decay, and the corruption of rust. Since the city was built, the oceans of earth had passed away and the desert had encompassed all the globe. The last mountains had been ground to dust by the winds and the rain, and the world was too weary to bring forth more. The city did not care; earth itself could crumble and Diaspora would still protect the children of its makers, bearing them and their treasures safely down the stream of time. They had forgotten much, but they did not know it. They were as perfectly fitted to their environment as it was to them -for both had been designed together. What was beyond the walls of the city was no concern of theirs; it was something that had been shut out of their minds. Diaspora was all that existed, all that they needed, all that they could imagine. It mattered nothing to them that man had once possessed the stars. Yet sometimes the ancient myths rose up to haunt them, and they stirred uneasily as they remembered the legends of the empire, when Diaspora was young and drew its lifeblood from the commerce of many suns. They did not wish to bring back the old days, for they were content in their eternal autumn. The glories of the empire belonged to the past, and could remain there-for they remembered how the empire had met its end, and at the thought of the invaders the chill of space itself came seeping into their bones. Then they would turn once more to the life and warmth of the city, to the long golden age whose beginning was already lost and whose end was yet more distant. Other men had dreamed of such an age, but they alone had achieved it. They had lived in the same city, had walked the same miraculously unchanging streets, while more than a billion years had worn away.

  It had taken them many hours to fight their way out of the cave of the white worms. Even now, they could not be sure that some of the pallid monsters were not pursuing them -and the power of their weapons was almost exhausted. Ahead, the floating arrow of light that had been their mysterious guide through the labyrinths of the crystal mountain still beckoned them on. They had no choice but to follow it, though as it had done so many times before it might lead them into yet more frightful dangers. Alvin glanced back to see if all his companions were still with him. Alystra was close behind, carrying the sphere of cold but ever-burning light that had revealed such horrors and such beauty since their adventure had begun. The pale white radiance flooded the narrow corridor and splashed from the glittering walls; while its power lasted, they could see where they were going and could detect the presence of any visible dangers. But the greatest dangers in these caves, Alvin knew too well, were not the visible ones at all. Behind Alystra, struggling with the weight of their projectors, came brilliant and lorans. Alvin wondered briefly why those projectors were so heavy, since it would have been such a simple matter to provide them with gravity neutralizers. He was always thinking of points like this, even in the midst of the most desperate adventures. When such thoughts crossed his mind, it seemed as if the structure of reality trembled for an instant, and that behind the world of the senses he caught a glimpse of another and totally different universe.... The corridor ended in a blank wall. Had the arrow betrayed them again? No-even as they approached, the rock began to crumble into dust. Through the wall pierced a spinning metal spear, which broadened rapidly into a giant screw. Alvin and his friends moved back, waiting for the machine to force its way into the cave. With a deafening screech of metal upon rock-which surely must echo through all the recesses of the mountain, and waken all its nightmare brood!-the sub terrene smashed through the wall and came to rest beside them. A massive door opened, and callistron appeared, shouting to them to hurry. ("Why callistron?" wondered Alvin. "What's he doing here?") a moment later they were in safety, and the machine lurched forward as it began its journey through the depths of the earth.

  The adventure was over. Soon, as always happened, they would be home, and all the wonder, the terror, and the excitement would be behind them. They were tired and content. Alvin could tell from the tilt of the floor that the sub terrene was heading down into the earth. Presumably callistron knew what he was doing, and this was the way that led to home. Yet it seemed a pity... "Callistron," he said suddenly, "why don't we go upward? No one knows what the crystal mountain really looks like. How wonderful it would be to come out somewhere on its slopes, to see the sky and all the land around it. We've been underground long enough." even as he said these words, he somehow knew that they were wrong. Alystra gave a strangled scream, the interior of the sub terrene wavered like an image seen through water, and behind and beyond the metal walls that surrounded him Alvin once more glimpsed that other universe. The two worlds seemed in conflict, first one and then the other predominating. Then quite suddenly, it was all over. There was a snapping, rending sensation-and the dream had ended. Alvin was back in Diaspora, in his own familiar room, floating a foot or two above the floor as the gravity field protected him from the bruising contact of brute matter.

  He was himself again. This was reality-and he knew exactly what
would happen next. Alystra was the first to appear. She was more upset than annoyed, for she was very much in love with Alvin. "Oh, Alvin!" she lamented as she looked down at him from the wall in which she had apparently materialized, "it was such an exciting adventure! Why did you have to spoil it?" "I'm sorry. I didn't intend to -- I just thought it would be a good idea..." He was interrupted by the simultaneous arrival of callistron and floranus. "Now listen, Alvin," began callistron. "This is the third time you've interrupted a saga. You broke the sequence yesterday by wanting to climb out of the valley of rainbows. And the day before you upset everything by trying to get back to the origin in that time track we were exploring. If you won't keep the rules, you'll have to go by yourself." he vanished in high dudgeon taking floranus with him. Narillian never appeared at all; he was probably too fed up with the whole affair. Only the image of alystra was left, looking sadly down at alvin. Alvin tilted the gravity field, rose to his feet, and walked toward the table he had materialized. A bowl of exotic fruit appeared upon it-not the food he had intended, for in his confusion his thoughts had wandered: not wishing to revealhis error, he picked up the least dangerous-looking of the fruits and started to suck it cautiously. "Well," said alystra at last, "what are you going to do?" "i can't help it," he said a little sulkily. "I think the rules are stupid. Besides, how can i remember them when i'm living a saga? I just behave in the way that seems natural. Didn't you want to look at the mountain?" alystra's eyes widened with horror. "That would have meant going outside!" she gasped. Alvin knew that it was useless to argue further. Here was the barrier that sundered him from all the people of his world, and which might doom him to a life of frustration. He was always wanting to go outside, both in reality and in dream. Yet to everyone in diaspar, "outside" was a nightmare that they could not face. They would never talk about it if it could be avoided; it was something unclean and evil. Not even jeserac his tutor, would tell him why. Alystra was still watching him with puzzled but tender eyes. "You're unhappy, alvin," she said. ` No one should be unhappy in diaspar. Let me come over and talk to you." ungallantly, alvin shook his head. He knew where that would lead and at the moment he wanted to be alone. Doubly disappointed, alystra faded from view. In a city of ten million human beings, thought alvin, there was no one to whom he could really talk. Eriston and etania were fond of him in their way, but now that their term of guardianship was ending, they were happy enough to leave him to shape his own amusements and his own life. In the last few years, as his divergence from the standard pattern became more and more obvious, he had often felt his parents' resentment. Not with him-that perhaps, was something he could have faced and fought-but with the sheer bad luck that had chosen them from all the city's millions, to meet him when he walked out of the hall of creation twenty years ago. Twenty years. He could remember the first moment, and the first words he had ever heard: "welcome, alvin. I am eriston, your appointed father. This is etania, your mother." the words had meant nothing then, but his mind had recorded them with flawless accuracy. He remembered how he had looked down at his body; it was an inch or two taller now, but had scarcely altered since the moment of his birth. He had come almost fully grown into the world, and would have changed little save in height when it was time to leave it a thousand years hence. Before that first memory, there was nothing. One day, perhaps, that nothingness would come again, but that was a thought too remote to touch his emotions in any way. He turned his mind once more toward the mystery of his birth. It did not seem strange to alvin that he might be created, in a single moment of time, by the powers and forces that materialized all the other objects of his everyday life. No; that was not the mystery. The enigma he had never been able to solve, and which no one would ever explain to him, was his uniqueness. Unique. It was a strange, sad word-and a strange, sad thing to be. When it was applied to him-as he had often heard it done when no one thought he was listening-it seemed to possess ominous undertones that threatened more than his own happiness. His parents, his tutor, everyone he knew, had tried to protect him from the truth, as if anxious to preserve the innocence of his long childhood. The pretense must soon be ended; in a few days he would be a full citizen of diaspar, and nothing could be withheld from him that he wished to know. Why, for example, did he not fit into the sagas? Of all the thousands of forms of recreation in the city, these were the most popular. When you entered a saga, you were not merely a passive observer, as in the crude entertainments of primitive times which alvin had sometimes sampled. You were an active participant and possessed-or seemed to possess-free will. The events and scenes which were the raw material of your adventures might have been prepared beforehand by forgotten artists, but there was enough flexibility to allow for wide variation. You could go into these phantom worlds with your friends, seeking the excitement that did not exist in diaspar-and as long as the dream lasted there was no way in which it could be distinguished from reality. Indeed, who could be certain that diaspar itself was not the dream? No one could ever exhaust all the sagas that had been conceived and recorded since the city began. They played upon all the emotions and were of infinitely varying subtlety. Some-those popular among the very young-were uncomplicated dramas of adventure and discovery. Others were purely explorations of psychological states, while others again were exercises in logic or mathematics which could provide the keenest of delights to more sophisticated minds. Yet though the sagas seemed to satisfy his companions, they left alvin with a feeling of incompleteness. For all their color and excitement, their varying locales and themes, there was something missing. The sagas, he decided, never really got anywhere. They were always painted on such a narrow canvas. There were no great vistas, none of the rolling landscapes for which his soul craved. Above all, there was never a hint of the immensity in which the exploits of ancient man had really taken place -the luminous void between the stars and planets. The artists who had planned the sagas had been infected by the same strange phobia that ruled all the citizens of diaspar. Even their vicarious adventures must take place cozily indoors, in subterranean caverns, or in neat little valleys surrounded by mountains that shut out all the rest of the world. There was only one explanation. Far back in time, perhaps before diaspar was founded, something had happened that had not only destroyed man's curiosity and ambition, but had sent him homeward from the stars to cower for shelter in the tiny closed world of earth's last city. He had renounced the universe and returned to the artificial womb of diaspar. The flaming, invincible urge that had once driven him over the galaxy, and to the islands of mist beyond, had altogether died. No ships had entered the solar system for countless aeons; out there among the stars the descendants of man might still be building empires and wrecking suns-earth neither knew nor cared. Earth did not. But alvin did.

  The room was dark save for one glowing wall, upon which the tides of color ebbed and flowed as alvin wrestled with his dreams. Part of the pattern satisfied him; he had fallen in love with the soaring lines of the mountains as they leaped out of the sea. There was a power and pride about those ascending curves; he had studied them for a long time, and then fed them into the memory unit of the visualizes, where they would be preserved while he experimented with the rest of the picture. Yet something was eluding him, though what it was he did not know. Again and again he had tried to fill in the blank spaces, while the instrument read the shifting patterns in his mind and materialized them upon the wall. It was no good. The lines were blurred and uncertain, the colors muddy and dull. If the artist did not know his goal, even the most miraculous of tools could not find it for him. Alvin canceled his unsatisfactory scribblings and stared morosely at the three-quarters-empty rectangle he had been trying to fill with beauty. On a sudden impulse, he doubled the size of the existing design and shifted it to the center of the frame. No-that was a lazy way out, and the balance was all wrong. Worse still, the change of scale had revealed the defects in his construction, the lack of certainty in those atfirst-sight confident lines. He would have
to start all over again. "Total erasure," he ordered the machine. The blue of the sea faded; the mountains dissolved like mist, until only the blank wall remained. They were as if they had never beenas if they were lost in the limbo that had taken all earth's seas and mountains ages before alvin was born. The light came flooding back into the room and the luminous rectangle upon which alvin had projected his dreams merged into its surroundings, to become one with the other walls. But were they walls? To anyone who had never seen such a place before, this was a very peculiar room indeed. It was utterly featureless and completely devoid of furniture, so that it seemed as if alvin stood at the center of a sphere. No visible dividing lines separated walls from floor or ceiling. There was nothing on which the eye could focus; the space enclosing alvin might have been ten feet or ten miles across, for all that the sense of vision could have told. It would have been hard to resist the temptation to walk forward, hands outstretched, to discover the physical limits of this extraordinary place. Yet such rooms had been "home" to most of the human race for the greater part of its history. Alvin had only to frame the appropriate thought, and the walls would become windows opening upon any part of the city he chose. Another wish, and machines which he had never seen would fill the chamber with the projected images of any articles of furniture he might need. Whether they were "real" or not was a problem that had bothered few men for the last billion years. Certainly they were no less real than that other impostor, solid matter, and when they were no longer required they could be returned to the phantom world of the city's memory banks. Like everything else in diaspar, they would never wear out-and they would never change, unless their stored patterns were canceled by a deliberate act of will. Alvin had partly reconstructed his room when a persistent, bell-like chime sounded in his ear. He mentally framed the admission signal, and the wall upon which he had just been painting dissolved once more. As he bad expected, there stood his parents, with jeserac a little behind them. The presence of his tutor meant that this was no ordinary family reunion -but he knew that already.... The illusion was perfect, and it was not lost when eriston spoke. In reality, as alvin was well aware, eriston etania, and jeserac were all miles apart, for the builders of the city had conquered space as completely as they had subjugated time. Alvin was not even certain where his parents lived. Among the multitudinous spires and intricate labyrinths of diaspar, for they had both moved since he had last been physically in their presence.
