The Complete Robot (Page 63)

"Yes?"

"Was it not possible to suppose that passage from a lie to the truth was easy, while passage from the truth to a lie was difficult? And in that case, would not the robot in stasis have been going from a truth to a lie, and since R. Preston was in stasis, might one not have drawn the conclusion that it was Dr. Humboldt who was innocent and Dr. Sabbat who was guilty?"

"Yes, R. Daneel. It was possible to argue that way, but it was the other argument that proved right. Humboldt did confess, didn’t he?"

"He did. But with arguments possible in both directions, how could you, friend Elijah, so quickly pick the correct one?"

For a moment, Baley’s lips twitched. Then he relaxed and they curved into a smile. "Because, R. Daneel, I took into account human reactions, not robotic ones. I know more about human beings than about robots. In other words, I had an idea as to which mathematician was guilty before I ever interviewed the robots. Once I provoked an asymmetric response in them, I simply interpreted it in such a way as to place the guilt on the one I already believed to be guilty. The robotic response was dramatic enough to break down the guilty man; my own analysis of human behavior might not have been sufficient to do so."

"I am curious to know what your analysis of human behavior was?"

"Jehoshaphat, R. Daneel; think, and you won’t have to ask. There is another point of asymmetry in this tale of mirror-image besides the matter of true-and-false. There is the matter of the age of the two mathematicians; one is quite old and one is quite young."

"Yes, of course, but what then?"

"Why, this. I can see a young man, flushed with a sudden, startling and revolutionary idea, consulting in the matter an old man whom he has, from his early student days, thought of as a demigod in the field. I can not see an old man, rich in honors and used to triumphs, coming up with a sudden, startling and revolutionary idea, consulting a man centuries his junior whom he is bound to think of as a young whippersnapper-or whatever term a Spacer would use. Then, too, if a young man had the chance, would he try to steal the idea of a revered demigod? It would be unthinkable. On the other hand, an old man, conscious of declining powers, might well snatch at one last chance of fame and consider a baby in the field to have no rights he was bound to observe. In short, it was not conceivable that Sabbat steal Humboldt’s idea; and from both angles, Dr. Humboldt was guilty."

R. Daneel considered that for a long time. Then he held out his hand. "I must leave now, friend Elijah. It was good to see you. May we meet again soon."

Baley gripped the robot’s hand, warmly, "If you don’t mind, R. Daneel," he said, "not too soon."

Some Humanoid Robots The Tercentenary Incident

July 4, 2076-and for the third time the accident of the conventional system of numeration, based on powers of ten, had brought the last two digits of the year back to the fateful 76 that had seen the birth of the nation.

It was no longer a nation in the old sense; it was rather a geographic expression; part of a greater whole that made up the Federation of all of humanity on Earth, together with its offshoots on the Moon and in the space colonies. By culture and heritage, however, the name and the idea lived on, and that portion of the planet signified by the old name was still the most prosperous and advanced region of the world…And the President of the United States was still the most powerful single figure in the Planetary Council.

Lawrence Edwards watched the small figure of the President from his height of two hundred feet. He drifted lazily above the crowd, his flotron motor making a barely heard chuckle on his back, and what he saw looked exactly like what anyone would see on a holovision scene. How many times had he seen little figures like that in his living room, little figures in a cube of sunlight, looking as real as though they were living homunculi, except that you could put your hand through them.

You couldn’t put your hand through those spreading out in their tens of thousands over the open spaces surrounding the Washington Monument. And you couldn’t put your hand through the President. You could reach out to him instead, touch him, and shake his hand.

Edwards thought sardonically of the uselessness of that added element of tangibility and wished himself a hundred miles away, floating in air over some isolated wilderness, instead of here where he had to watch for any sign of disorder. There wouldn’t be any necessity for his being here but for the mythology of the value of "pressing the flesh."

Edwards was not an admirer of the President-Hugo Allen Winkler, fifty-seventh of the line.

To Edwards, President Winkler seemed an empty man, a charmer, a vote grabber, a promiser. He was a disappointing man to have in office now after all the hopes of those first months of his administration. The World Federation was in danger of breaking up long before its job had been completed and Winkler could do nothing about it. One needed a strong hand now, not a glad hand; a hard voice, not a honey voice.

There he was now, shaking hands-a space forced around him by the Service, with Edwards himself, plus a few others of the Service, watching from above.

The President would be running for re-election certainly, and there seemed a good chance he might be defeated. That would just make things worse, since the opposition party was dedicated to the destruction of the Federation.

Edwards sighed. It would be a miserable four years coming up-maybe a miserable forty-and all he could do was float in the air, ready to reach every Service agent on the ground by laser-phone if there was the slightest

He didn’t see the slightest. There was no sign of disturbance. Just a little puff of white dust, hardly visible; just a momentary glitter in the sunlight, up and away, gone as soon as he was aware of it.
