“Will you agree to its destruction, if it has broken First Law?”
“Yes,” said Susan Calvin, “because I know it hasn’t.”
Charles Randow lay in bed with his arm set and in a cast. His major suffering was still from the shock of those few moments in which he thought a robot was advancing on him with murder in its positronic mind. No other human had ever had such reason to fear direct robotic harm as he had had just then. He had had a unique experience.
Susan Calvin and Alfred Lanning stood beside his bed now; Peter Bogert, who had met them on the way, was with them. Doctors and nurses had been shooed out.
Susan Calvin said, “Now – what happened?” Randow was daunted. He muttered, “The thing hit me in the arm. It was coming at me.”
Calvin said, “Move further back in the story. What were you doing in my laboratory without authorization?”
The young computer swallowed, and the Adam’s apple in his thin neck bobbed noticeably. He was high-cheekboned and abnormally pale. He said, “We all knew about your robot. The word is you were trying to teach it to talk like a musical instrument. There were bets going as to whether it talked or not. Some said – uh – you could teach a gatepost to talk.”
“I suppose,” said Susan Calvin, freezingly, “that is meant as a compliment. What did that have to do with you?”
“I was supposed to go in there and settle matters – see if it would talk, you know. We swiped a key to your place and I waited till you were gone and went in. We had a lottery on who was to do it. I lost.”
“Then?”
“I tried to get it to talk and it hit me.”
“What do you mean, you tried to get it to talk? How did you try?”
“I – I asked it questions, but it wouldn’t say anything, and I had to give the thing a fair shake, so I kind of – yelled at it, and –”
“And?”
There was a long pause. Under Susan Calvin’s unwavering stare, Randow finally said, “I tried to scare it into saying something.” He added defensively, “I had to give the thing a fair shake.”
“How did you try to scare it?”
“I pretended to take a punch at it.”
“And it brushed your arm aside?”
“It hit my arm.”
“Very well. That’s all.” To Lanning and Bogert, she said, “Come, gentlemen.”
At the doorway, she turned back to Randow. “I can settle the bets going around, if you are still interested. Lenny can speak a few words quite well.”
They said nothing until they were in Susan Calvin’s office. Its walls were lined with her books, some of which she had written herself. It retained the patina of her own frigid, carefully ordered personality. It had only one chair in it and she sat down. Lanning and Bogert remained standing.
She said, “Lenny only defended itself. That is the Third Law: A robot must protect its own existence.”
“Except,” said Lanning forcefully, “when this conflicts with the First or Second Laws. Complete the statement! Lenny had no right to defend itself in any way at the cost of harm, however minor, to a human being.”
“Nor did it,” shot back Calvin, “knowingly. Lenny has an aborted brain. It had no way of knowing its own strength or the weakness of humans. In brushing aside the threatening arm of a human being it could not know the bone would break. In human terms, no moral blame can be attached to an individual who honestly cannot differentiate good and evil.”
Bogert interrupted, soothingly, “Now, Susan, we don’t blame. We understand that Lenny is the equivalent of a baby, humanly speaking, and we don’t blame it. But the public will. U. S. Robots will be closed down.”
“Quite the opposite. If you had the brains of a flea, Peter, you would see that this is the opportunity U. S. Robots is waiting for. That this will solve its problems.”
Lanning hunched his white eyebrows low. He said, softly, “What problems, Susan?”
“Isn’t the corporation concerned about maintaining our research personnel at the present – Heaven help us – high level?”
“We certainly are.”
“Well, what are you offering prospective researchers? Excitement? Novelty? The thrill of piercing the unknown? No! You offer them salaries and the assurance of no problems.”
Bogert said, “How do you mean, no problems?”
“Are there problems?” shot back Susan Calvin. “What kind of robots do we turn out? Fully developed robots, fit for their tasks. An industry tells us what it needs; a computer designs the brain; machinery forms the robot; and there it is, complete and done. Peter, some time ago, you asked me with reference to Lenny what its use was. What’s the use, you said, of a robot that was not designed for any job? Now I ask you – what’s the use of a robot designed for only one job? It begins and ends in the same place. The LNE models mine boron. If beryllium is needed, they are useless. If boron technology enters a new phase, they become useless. A human being so designed would be sub-human. A robot so designed is sub-robotic.”
“Do you want a versatile robot?” asked Lanning, incredulously. “Why not?” demanded the robopsychologist. “Why not? I’ve been handed a robot with a brain almost completely stultified. I’ve been teaching it, and you, Alfred, asked me what was the use of that. Perhaps very little as far as Lenny itself is concerned, since it will never progress beyond the five-year-old level on a human scale. But what’s the use in general? A very great deal, if you consider it as a study in the abstract problem of learning how to teach robots. I have learned ways to short-circuit neighboring pathways in order to create new ones. More study will yield better, more subtle and more efficient techniques of doing so.”
“Well?”
“Suppose you started with a positronic brain that had all the basic pathways carefully outlined but none of the secondaries. Suppose you then started creating secondaries. You could sell basic robots designed for instruction; robots that could be modeled to a job, and then modeled to another, if necessary. Robots would become as versatile as human beings. Robots could learn!”
They stared at her. She said, impatiently, “You still don’t understand, do you?”
“I understand what you are saying,” said Lanning.
“Don’t you understand that with a completely new field of research and completely new techniques to be developed, with a completely new area of the unknown to be penetrated, youngsters will feel a new urge to enter robotics? Try it and see.”
“May I point out,” said Bogert, smoothly, “that this is dangerous. Beginning with ignorant robots such as Lenny will mean that one could never trust First Law – exactly as turned out in Lenny’s case.”
“Exactly. Advertise the fact.”
“Advertise it!”
“Of course. Broadcast the danger. Explain that you will set up a new research institute on the moon, if Earth’s population chooses not to allow this sort of thing to go on upon Earth, but stress the danger to the possible applicants by all means.”
Lanning said, “For God’s sake, why?”
“Because the spice of danger will add to the lure. Do you think nuclear technology involves no danger and spationautics no peril? Has your lure of absolute security been doing the trick for you? Has it helped you to cater to the Frankenstein complex you all despise so? Try something else then, something that has worked in other fields.”
There was a sound from beyond the door that led to Calvin’s personal laboratories. It was the chiming sound of Lenny.
The robopsychologist broke off instantly, listening. She said, “Excuse me. I think Lenny is calling me.”
“Can it call you?” said Lanning.
“I said I’ve managed to teach it a few words.” She stepped toward the door, a little flustered. “If you will wait for me –”
They watched her leave and were silent for a moment. Then Lanning said, “Do you think there’s anything to what she says, Peter?”
“Just possibly, Alfred,” said Bogert. “Just possibly. Enough for US to bring the ma
tter up at the directors’ meeting and see what they say. After all, the fat is in the fire. A robot has harmed a human being and knowledge of it is public. As Susan says, we might as well try to turn the matter to our advantage. Of course, I distrust her motives in all this.”
“How do you mean?”
“Even if all she has said is perfectly true, it is only rationalization as far as she is concerned. Her motive in all this is her desire to hold on to this robot. If we pressed her” (and the mathematician smiled at the incongruous literal meaning of the phrase) “she would say it was to continue learning techniques of teaching robots, but I think she has found another use for Lenny. A rather unique one that would fit only Susan of all women.”
“I don’t get your drift.” Bogert said, “Did you hear what the robot was calling?”
“Well, no, I didn’t quite –” began Lanning, when the door opened suddenly, and both men stopped talking at once.
Susan Calvin stepped in again, looking about uncertainly. “Have either of you seen – I’m positive I had it somewhere about – Oh, there it is.”
She ran to a corner of one bookcase and picked up an object of intricate metal webbery, dumbbell shaped and hollow, with variously shaped metal pieces inside each hollow, just too large to be able to fallout of the webbing.
As she picked it up, the metal pieces within moved and struck together, clicking pleasantly. It struck Lanning that the object was a kind of robotic version of a baby rattle.
As Susan Calvin opened the door again to pass through, Lenny’s voice chimed again from within. This time, Lanning heard it clearly as it spoke the words Susan Calvin had taught it.
In heavenly celeste-like sounds, it called out, “Mommie, I want you. I want you, Mommie.”
And the footsteps of Susan Calvin could be heard hurrying eagerly across the laboratory floor toward the only kind of baby she could ever have or love.

2026 A.D.
CHILE STEPPED THROUGH the inner lock door, and turned white as it closed behind him. The woman at the data station shivered as she felt his presence.
“I’m sorry, Sheila,” he said hastily. “Rob wanted to use the lock himself right away, and said I should defrost inside.”
“Why didn’t he come through first? Armor doesn’t have anything like your heat capacity.”
“He didn’t say.” ZH50 had stood still since entering, using his own power to warm up; the frost was already disappearing from his extremities. Sheila McEachern waited, knowing there was nothing to be gained by complaining to the robot, her irritation giving way to curiosity anyway as the lock cycled again. She could hope, but not be sure, that Robert Ling had not wanted to annoy just to gain her full attention.
The valve slid open to reveal a human figure, its armor’s gold background fogging briefly under a layer of white as the ship’s air touched it. The man unclamped his bulky helmet as its contrasting black started to show again, and flipped it back.
“Chile, you’re in the way. Why did you think I wanted you inside first? I was hoping to see the new display as soon –”
“I can answer that.” The woman snorted. “You didn’t tell him why, just sent him first. Otherwise he’d have taken the reason as an order and given me frostbite while he plugged into the console.”
“I would not have injured you, Sheila.”
“Of course not, Chile. But you wouldn’t have minded making me uncomfortable, with a real order on file.”
“And you’re still in my way,” Ling cut in impatiently. ZH50 crossed to the data console in a single floating step, uncovered its input jack, and inserted the plug now extending from the heel of his right hand. The woman controlled herself; his metal was still cold enough to feel from a few centimeters away, but at least the frost was gone. She aimed her annoyance more appropriately.
“Why all this rush for a new picture? Did you finally find something which isn’t too radiation-saturated to date?” She disapproved basically of sarcasm, but had more control over aim than fire power. Ling knew her well enough to ignore the second question.
“We caught another glimpse of Chile’s ghost.”
“We?”
“We. The lovebirds saw it too, so I’m not floating.”
“Did Chile?”
“Not this time, Sheila,” the robot answered for himself. “I was with Luis and Chispa near the Banjo, at Square Fifty-four. Robert and the Eiras were at Ninety-one.” The woman frowned.
“Then why the hurry to get Chile inside?” she asked. “He could have been here long before you, if you started at the same time from those areas.”
“I didn’t think of him until I was nearly back. Then I had an idea, and needed him to check it. Luis and Chispa found two more of those blocks a while ago. The Eiras and I heard them; you probably weren’t listening. Of course Chile hadn’t filed them with Dumbo yet.”
“I was listening. And your idea needs all their positions.”
“Right.” If Ling noticed the remaining sarcasm he ignored it. “Look. Whether we want to believe it or not, those cubes are artificial. Shape may be an intrinsic property of a natural crystal, but size isn’t. Even if they were life forms, they wouldn’t all match dimensions to four figures. It occurred to me that they might be sensors – detectors of some sort.”
“It occurred to Chispa days ago. You didn’t want to believe then that anyone else beat us to Miranda.”
“I know. I still don’t. There’s no way a group from Earth could have set up this expensive a trip in secret, and I can’t make myself believe the other explanation. We’ve been hoping for ETI too long. But I thought of a way of checking.” He smiled, with a distant look on his face as though he were contemplating the approach of Fame.
“And?”
“The things radiate – broadcast – infrared patterns, nonthermal ones, at unpredictable times.”
“I know.”
“Well, we’ve mapped way beyond the local horizon. If that IR output is being coordinated, there must be a central unit they can all reach. You could have Dumbo mark any points on the map which are in eyeball touch with all the cube positions at once. If we’re lucky, there’ll only be a few. If we’re very lucky –”
The woman was already keying at Dumbo, the central data unit.
“And if there aren’t any?” she asked dryly.
“Well, it won’t prove I’m wrong. It’ll just mean...” His voice trailed off as the display popped into view, and a grin split his freckled face. Sheila rolled her eyes zenithward; it would happen to Ling. As though he weren’t bubbly enough already.
Chile accompanied them, naturally. The display had indicated a projecting spur at the top of a cliff which Chispa Jengibre had called El Barco, from the shadow pattern the sun was casting along its face when she first saw it. It was in block ninety-two, a little over twenty kilometers from the Dibrofiad. The location was understandable enough by hindsight; there would be splendid line-of-sight coverage from there. However, a one-hundred-fifty meter fall on Miranda would be dangerous for a human being; even if no limbs were broken, damage to the armor needed against the airless heat sink and Uranian radiation was nearly certain. While Dibrofiad’s crew had gotten fairly used to two-plus percent normal gravity, this hadn’t made anyone a good walker; it was doubtful that anything ever would.
Chile, therefore, viewed a human trip to the cliff as a parent would his one-year-old toddling out on a diving board. The actual visit to the spur must be robot’s work, if it had to be done.
The walkers looked ridiculous, trunks leaning forward like a sprinter about to leave the block, but legs almost straight along the same line. Walking is essentially coordinated falling forward, and Miranda needs every advantage to provide much fall. Thrust came from lower leg muscles bending and straightening ankles to drive toes hooked into surface irregularities, since bending the knees very far made them hit the ground. Bumps and cracks were fortunately numerous, possibly due to the expansion of freezing water, tho
ugh none of the crew had a clear idea how water could ever have been liquid this far from the sun. The “hikers” carried alpenstocks, but used a free finger more often than the stick to keep faces off the ground. Luis, Chispa’s husband, had remarked that walking could be called body-surfing if Miranda’s water were only melted. His wife insisted that the analogy was too strained, though it was she who had insisted on the robot’s name being spelled to look Spanish after the Gold team had won the throw for right to select the name itself.
Whatever one chose to call it, Sheila was as good at “walking” as Ling; everyone, regardless of specialty, shared the field exploration, which was the most time-consuming crew duty.
Chile would stay ahead of them, since he alone dared to leap. His memory held a detailed surface map for sixty or seventy kilometers around Dibrofiad, so he didn’t have to see his target; he could jump with enough spin control to be sure of landing on his feet; and being built to operate in the sixty Kelvin temperature range, he had no armor to worry about.
The greenish bulk of Uranus hung beyond Stegosaur, the same jagged ridge of carbon-darkened ice it had silhouetted ever since their arrival, changing visibly only in shape as the sun circled above it to produce phase. At the moment it was about eight hours from narrowest crescent, and a slight darkening of the green, showing through the deeper notches of Stego, showed that the fuzzy terminator of the gas giant would be in view shortly.
The party turned to put the planet to their left rear and the sun behind them, and set out. Neither of the other human couples could be seen, but Ling had reached them on the low-frequency sets to report that the Gold team was going out. Bronwen Eira, engineer and captain of Dibrofiad, had acknowledged.
Little was said even by Ling as they went; each person was coming to terms, in his or her own way, with the increasing certainty that they would be the first group to prove the reality of extraterrestrial intelligence. It was hard to believe, like the “yes” to a proposal. Sheila, accustomed to the rugged Miranda landscape as she was, found it now showing a strange, dreamlike aspect; Robert scarcely saw it at all through constantly changing visions of the futures the next hour or two might crystallize. His usual free-time occupation of talking his companion into sharing a name had been put aside, not entirely to her relief. Even the Green and Orange teams, the Jengibres and Eiras, though not going along, were having trouble concentrating on their work; all four had thought of dropping it and following the Golds, though none had so far suggested it aloud.
