Free The City and the Stars / The Sands of Mars by Arthur C. Clarke Page A

clear and sharp when he turned his memory upon it. Like beads upon a string, this life and all the ones before it stretched back through the ages; he could seize and re-examine any one he wished. Most of those older Khedrons were strangers to him now; the basic patterns might be the same, but the weight of experience separated him from them forever. If he wished, he could wash his mind clear of all his earlier incarnations, when next he walked back into the Hall of Creation to sleep until the city called him forth again. But that would be a kind of death, and he was not ready for that yet. He was still prepared to go on collecting all that life could offer, like a chambered nautilus patiently adding new cells to its slowly expanding spiral.
    In his youth, he had been no different from his companions. It was not until he came of age and the latent memories of his earlier lives came flooding back that he had taken up the role for which he had been destined long ago. Sometimes he felt resentment that the intelligences which had contrived Diaspar with such infinite skill could even now, after all these ages, make him move like a puppet across their stage. Here, perhaps, was a chance of obtaining a long-delayed revenge. A new actor had appeared who might ring down the curtain for the last time on a play that already had seen far too many acts.
    Sympathy, for one whose loneliness must be even greater than his own; an ennui produced by ages of repetition; and an impish sense of fun— these were the discordant factors that prompted Khedron to act.
    “I may be able to help you,” he told Alvin, “or I may not. I don’t wish to raise any false hopes. Meet me in half an hour at the intersection of Radius 3 and Ring 2. If I cannot do anything else, at least I can promise you an interesting journey.”
    Alvin was at the rendezvous ten minutes ahead of time, though it was on the other side of the city. He waited impatiently as the moving ways swept eternally past him, bearing the placid and contented people of the city about their unimportant business. At last he saw the tall figure of Khedron appear in the distance, and a moment later he was for the first time in the physical presence of the Jester. This was no projected image; when they touched palms in the ancient greeting, Khedron was real enough.
    The Jester sat down on one of the marble balustrades and regarded Alvin with a curious intentness.
    “I wonder,” he said, “if you know what you are asking. And I wonder what you would do if you obtained it. Do you really imagine that you could leave the city, even if you found a way?”
    “I am sure of it,” replied Alvin, bravely enough, though Khedron could sense the uncertainty in his voice.
    “Then let me tell you something which you may not know. You see those towers there?” Khedron pointed to the twin peaks of Power Central and Council Hall, staring at each other across a canyon a mile deep. “Suppose I were to lay a perfectly firm plank between those two towers— a plank only six inches wide. Could you walk across it?”
    Alvin hesitated.
    “I don’t know,” he answered. “I wouldn’t like to try.”
    “I’m quite sure you could never do it. You’d get giddy and fall off before you’d gone a dozen paces. Yet if that same plank was supported just clear of the ground, you’d be able to walk along it without difficulty.”
    “And what does that prove?”
    “A simple point I’m trying to make. In the two experiments I’ve described, the plank would be exactly the same in both cases. One of those wheeled robots you sometimes meet could cross it just as easily if it was bridging those towers as if it was laid along the ground. We couldn’t, because we have a fear of heights. It may be irrational, but it’s too powerful to be ignored. It is built into us; we are born with it.
    “In the same way, we have a fear of space. Show any man in Diaspar a road out of the city— a road that might be just like this road
