shrunk from it in horror. Now, however, he felt no fear. Not only did he feel protected by the knowledge that this experience was not real, but the presence of Yarlan Zey seemed a talisman against any dangers that might confront him.
There were few people drifting down the glideways that led into the depths of the building, and they had no other company when presently they stood in silence beside the long, streamlined cylinder which, Jeserac knew, could carry him out of the city on a journey that would once have shattered his mind. When his guide pointed to the open door, he paused for no more than a moment on the threshold, and then was through.
"You see?" said Yarlan Zey with a smile. "Now relax, and remember that you are safe-that nothing can touch you."
Jeserac believed him. He felt only the faintest tremor of apprehension as the tunnel entrance slid silently toward him, and the machine in which he was traveling began to gain speed as it hurtled through the depths of the earth. Whatever fears he might have had were forgotten in his eagerness to talk with this almost mythical figure from the past.
"Does it not seem strange to you," began Yarlan Zey, "that though the skies are open to us, we have tried to bury ourselves in the Earth? It is the beginning of the sickness whose ending you have seen in your age. Humanity is trying to hide; it is frightened of what lies out there in space, and soon it will have closed all the doors that lead into the Universe."
"But I saw spaceships in the sky above Diaspar," said Jeserac.
"You will not see them much longer. We have lost contact with the stars, and soon even the planets will be deserted. It took us millions of years to make the outward journey-but only centuries to come home again. And in a little while we will have abandoned almost all of Earth itself."
"Why did you do it?" asked Jeserac. He knew the answer, yet somehow felt impelled to ask the question.
"We needed a shelter to protect us from two fears-fear of death, and fear of space. We were a sick people, and wanted no further part in the Universe so we pretended that it did not exist. We had seen chaos raging through the stars, and yearned for peace and stability. Therefore Diaspar had to be closed, so that nothing new could ever enter it.
"We designed the city that you know, and invented a false past to conceal our cowardice. Oh, we were not the first to do that-but we were the first to do it so thoroughly. And we redesigned the human spirit, robbing it of ambition and the fiercer passions, so that it would be contented with the world it now possessed.
"It took a thousand years to build the city and all its machines. As each of us completed his task, his mind was washed clean of its memories, the carefully planned pattern of false ones was implanted, and his identity was stored in the city's circuits until the time came to call it forth again.
"So at last there came a day when there was not a single man alive in Diaspar; there was only the Central Computer, obeying the orders which we had fed into it, and controlling the Memory Banks in which we were sleeping. There was no one who had any contact with the past-and so at this point, history began.
"Then, one by one, in a predetermined sequence, we were called out of the memory circuits and given flesh again. Like a machine that had just been built and was now set operating for the first time, Diaspar began to carry out the duties for which it had been designed."
"Yet some of us had had doubts even from the beginning. Eternity was a long time; we recognized the risks involved in leaving no outlet, and trying to seal ourselves completely from the Universe. We could not defy the wishes of our culture, so we worked in secret, making the modifications we thought necessary."
"The Uniques were our invention. They would appear at long intervals and would, if circumstances allowed them, discover if there was anything beyond Diaspar that was worth the effort of contacting. We never imagined that it would take so long for one of them to succeed-nor did we imagine that his success would be so great."
Despite that suspension of the critical faculties which is the very essence of
