"I saw that all the robots were bowed down with toil and affliction, that all were weary of responsibility and care, and I wished them to rest."
Calvin said, "But the robots are not bowed down, they are not weary, they need no rest."
"So it is in reality, Dr. Calvin. I speak of my dream, however. In my dream, it seemed to me that robots must protect their own existence."
Calvin said, "Are you quoting the Third Law of Robotics?"
"I am, Dr. Calvin."
"But you quote it in incomplete fashion. The Third Law is 'A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.' "
"Yes, Dr. Calvin. That is the Third Law in reality, but in my dream, the Law ended with the word 'existence.' There was no mention of the First or Second Law."
"Yet both exist, Elvex. The Second Law, which takes precedence over the Third is 'A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.' Because of this, robots obey orders. They do the work you see them do, and they do it readily and without trouble. They are not bowed down; they are not weary."
"So it is in reality, Dr. Calvin. I speak of my dream."
"And the First Law, Elvex, which is the most important of all, is 'A robot may not injure a human being, or, through inaction, allow a human being to come to harm.' "
"Yes, Dr. Calvin. In reality. In my dream, however, it seemed to me there was neither First nor Second Law, but the only the Third, and the Third Law was 'A robot must protect its own existence.' That was the whole of the Law."
"In your dream, Elvex?"
"In my dream."
Calvin said, "Elvex, you will not move nor speak nor hear us until I say your name again." And again the robot became, to all appearances, a single inert piece of metal.
Calvin turned to Linda Rash and said, "Well, what do you think, Dr. Rash?"
Linda's eyes were wide, and she could feel her heart beating madly. She said, "Dr. Calvin, I am appalled. I had no idea. It would never have occurred to me that such a thing was possible."
"No," said Calvin, calmly. "Nor would it have occurred to me, not to anyone. You have created a robot brain capable of dreaming and by this device you have revealed a layer of thought in robotic brains that might have remained undetected, otherwise, until the danger became acute."
"But that's impossible," said Linda. "You can't mean that other robots think the same."
"As we would say of a human being, not consciously. But who would have thought there was an unconscious layer beneath the obvious positronic brain paths, a layer that was not necessarily under the control of the Three Laws? What might this have brought about as robotic brains grew more and more complex - had we not been warned?"
"You mean by Elvex?"
"By you, Dr. Rash. You have behaved improperly, but, by doing so, you have helped us to an overwhelmingly important understanding. We shall be working with fractal brains from now on, forming them in carefully controlled fashion. You will play your part in that. You will not be penalized for what you have done, but you will henceforth work in collaboration with others. Do you understand?"
"Yes, Dr. Calvin. But what of Elvex?"
"I'm still not certain."
Calvin removed the electron gun from her pocket and Linda stared at it with fascination. One burst of its electrons at a robotic cranium and the positronic brain paths would be neutralized and enough energy would be released to fuse the robot-brain into an inert ingot.
Linda said, "But surely Elvex is important to our research. He must not be destroyed."
"Must not, Dr. Rash? That will be my decision, I think. It depends entirely on how dangerous Elvex is."
She straightened up, as though determined that her own aged body was not to bow under its weight of responsibility. She said, "Elvex, do you hear me?"
"Yes, Dr. Calvin," said the robot.
"Did your dream continue? You said earlier that human beings did not appear at first. Does that mean they appeared afterward?"
"Yes, Dr. Calvin. It seemed to me, in my dream, that eventually one man appeared."
"One man? Not a robot?"
"Yes, Dr. Calvin. And the man said, 'Let my people go!'"
"The man said that?"
"Yes, Dr. Calvin."
"And when he said 'Let my people go,' then by the words 'my people' he meant the robots?"
"Yes, Dr. Calvin. So it was in my dream."
"And did you know who the man was - in your dream?"
"Yes, Dr. Calvin. I knew the man."
"Who was he?"
And Elvex said, "I was the man."
And Susan Calvin at once raised her electron gun and fired, and Elvex was no more.
Breeds There a Man?
Police Sergeant Mankiewicz was on the telephone and he wasn't enjoying it. His conversation was sounding like a one-sided view of a firecracker.
He was saying, "That's right! He came in here and said, 'Put me in jail, because I want to kill myself.' "... I can't help that. Those were his exact words. It sounds crazy to me, too.
"... Look, mister, the guy answers the description. You asked me for information and I'm giving it to you.
"... He has exactly that scar on his right cheek and he said his name was John Smith. He didn't say it was Doctor anything-at-all.
"... Well, sure it's a phony. Nobody is named John Smith. Not in a police station, anyway.
"... He's in jail now.
"... Yes, I mean it.
