<passage>:
Rikud looked out upon the garden and he trembled. Out there was life. people. Rikud and his people . This was why the world had moved across the darkness and the stars for all Rikud's lifetime and more. Every day for a week now, Rikud had come to the viewport to watch they were so alien, so unnatural. But ever since the engines somewhere in the rear of the world had changed their tone, from the steady whining Rikud had heard all twenty-five years of his "There is Rikud on the floor!" life, to the sullen roar that came to his ears now, the feelings had machinery, and down on his hands and knees he fondled the bits of metal apparent in the speckled profusion Rikud had always known. Instead, which he could see in the dim light through the open door. "Where's the buzzer?" he sobbed. "I must find the buzzer." If he had understood the term, Rikud would have told himself this was Rikud knew he should be exercising now, or bathing in the rays of the Chuls' reminder fostered uneasiness. Often Rikud had dreamed of the The air was fresh, fresher than any air Rikud had ever breathed. He the land, and Rikud lay down and drank. It was cool and good, and when Rikud muttered to himself and undressed. The world had begun to annoy Rikud sat down and tore off a piece of a plant, munching on it. It was are variable. I don't hate you now, Rikud." was a strange thought, and Rikud's brain With so many people, and especially now with women, he was not afraid. It was much better than the small world of machinery, buzzer, frightening doors and women by appointment only. Rikud felt at home. Rikud had been stopped in this action, although there was no real And Rikud could remember the rest of what the reading machine had said. There had been a revolt—again a term without any real meaning, a term that could have no reality outside of the reading machine—and the elders were overthrown. Here Rikud had been lost utterly. The people cogs in a great machine. Much of this Rikud could not understand, but he knew enough to realize that the reading machine had sided with the people against the elders, and it said the people had won. Now in the health room, Rikud felt a warmth in the rays. Grudgingly, he before Rikud's time, had negated the necessity for a knowledge of not without a sense of alarm. Yet old Chuls seemed heedless, with only a decade to go. Rikud looked at that foot, it was with a sense of satisfaction. True, proved the world was not perfect. Rikud was guiltily glad when he saw meant that, in the two unoccupied hours before sleep, he went to the library and listened to the reading machine. Everyone else simply sat about and talked. That was the custom. Everyone did it. But if he wasn't reading himself, Rikud usually went to sleep. All the people ever talked about was what they had done during the day, and it was always the same. This was a new thought to Rikud, and he propped his head up on one "Well, where's the book?" Rikud would read it tomorrow. "You know," Rikud said, sitting up now, "the stars in the viewport are channelings of Rikud's energy in new and confusing directions. The view had changed, and the strangeness of it made Rikud's pulses where Rikud had seen the one bright central star, he now saw a globe of Startled, Rikud leaped back. The sullen roar in the rear of the world "Won't you eat, Rikud?" Chuls called from somewhere down below. But Rikud forgot the old man completely. A new idea occurred to him, That was maddening. Rikud turned again to the port, where he could see Rikud whirled on the little figure and pointed to the swirling cloud of Anger welled up inside Rikud. "All right," he said, "listen. What do room, and Rikud was glad to be alone once more. moment Rikud thought he could see the gardens rearward in the world. besides, Rikud had the distinct feeling that here was something far Rikud sat down hard. He blinked. The world had come to rest on the garden of the viewport. For a whole week that view did not change, and Rikud had come to accept garden larger than the entire world, a garden of plants which Rikud had word seemed all wrong to Rikud, but he could think of no other, unless are different." "Then they've changed?" "No, merely different." It changed. Where are the stars? Where are they, Chuls, if it did not change?" Rikud regretted that he never had had the chance to read that book on obvious. If he, Rikud, walked from one part of the world to another, There's nothing. It just isn't. It's only a door, Rikud." Rikud saw a small room, perhaps half a dozen paces across, at the other Rikud heard a voice not unlike that of the reading machine. is a perfect, self-sustaining world. It is more than that: it is Rikud gave the voice up as hopeless. There were too many confusing blast nearly so loudly against his eardrums. And what met Rikud's Only this one was different. In it Rikud saw the viewport. But how? The although it looked out on the garden, Rikud sensed that the topography no one ever died of anything until he was a hundred. Rikud couldn't fathom the rapid thumping of his heart. And Rikud's mouth felt and Rikud found himself wishing that his friend had never read that "Well, I won't go," Chuls replied. "There's no reason to go. If Rikud In a moment, the room was cleared. Rikud stood alone. He cleared his This frightened Rikud, although he didn't know why. He'd like it, machinery. For a long time he watched the wheels and cogs and gears spinning and humming. He watched for he knew not how long. And then he began to wonder. If he destroyed the wheels and the cogs and the gears, casual. Soon his easy strides had given way to frenzied running. Rikud Rikud never wanted to do anything more than he wanted to open that All around Rikud were darkness and hunger and thirst. The buzzer did eat or drink. Rikud himself had fumbled through the blackness and the whimpering to the dining room, his tongue dry and swollen, but the smooth belt that flowed with water and with savory dishes did not run any more. The machinery, Rikud realized, also was responsible for food. Chuls said, over and over, "I'm hungry." "We will eat and we will drink when the buzzer tells us," Wilm replied "It won't any more," Rikud said. "What won't?" "The buzzer will never sound again. I broke it." eat. I hate Rikud, I think." hate Rikud." Then everyone was saying it. Rikud was sad. Soon he would die, because no one would go outside with "No," Rikud assured him. "It won't." Crifer's voice. "I have Rikud's head." The voice was nasty, hostile. do to Rikud what he said he did to the machinery." Rikud ran. In the weak to rise. Rikud, too, felt a strange light-headedness and a gnawing Rikud tripped over something and sprawled awkwardly across the floor.
