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
