“Slow down,” Powell cautioned. “Let’s explore this further. What does the Napoleon robot necessarily know and believe, to execute his mission of halting Project Io?” He thought aloud as he soared to and fro:
“He can operate a spacecraft, a communications system, et cetera. Therefore he has a certain amount of independent decision-making capability, though scarcely equal to Jack’s. Otherwise simpleminded, he has no way of knowing the viroid story is false. I daresay he’s been forbidden to tune in any outside ‘cast, and told to ignore whatever he might overhear accidentally. His mission is to warn Jack about the viroids, and about the wicked men whose robots will try to talk Jack into going back to work. To this end, it’ll be reasonable to him that he claim to being human himself, and that his image be projected as human. He’ll have no inhibitions about such a pious deception, if it’s used on another robot.”
“Ah-ha!” Borup exulted. “We have him! He will be listening and watching when you next call Yack. He will see you are human, and obey your orders.”
“He will not,” Powell said bleakly. “I assume the conspirators have planned ahead. Ifl were in charge, I’d not only program his transmitter to make him look human, I’d program his receiver to make any in-calling human look like a robot. “
“Whoof!” puffed Borup, and sought the akvavit.
“Yeah,” Donovan agreed. “That pretty well shields him from any nagging doubts, which makes him better able to quiet down any that Jack expresses. “
“He might entertain the possibility that his communicator is deceiving him,” Powell said, “but he can’t act on it, when his orders are to prevent a catastrophe. For instance, we could invite him to come here and meet us. I’ll bet he’d refuse, because we, if we’re enemy robots as he’s been told, we’d overpower him.”
Borup nodded. “I see. I see. It is a classic conundrum, no? Plato’s cave.”
“Huh?” grunted Donovan.
“You do not know? Well, I have more time to read than you do, on my travels. The ancient Greek philosopher Plato pointed out that our information about the material world comes to us entirely t’rough our senses, and how do we know they tell us true? Rather, we know they are often wrong. We must do the best we can. He said we are like prisoners chained in a cave who cannot see the outside, yust the shadows of t’ings there that are cast on the wall. From this they must try to guess what the reality is. “
“Kind of an airy notion.”
“Ha, you would refute solipsism like Dr. Samuel Yohnson, by kicking a stone-”
“Never mind the dialectics,” Powell interrupted. “You have hit on a good analogy, Svend. We are trapped in Plato’s cave, all three parties of us. We can’t physically go to each other. The only information we get is what comes over the communication beams; and it could be lies. We don’t even know that the Napoleon robot exists. We’re assuming so, but maybe he really is only a figment of Jack’s deranged imagination. If Napoleon does exist, then he knows that his own projected image is a man’s; but every image he receives is a robot’s, and he believes-he must believe, if he’s to serve his bosses reliably-that that is true. As for Jack, if he isn’t hallucinating, then every image he receives is human, and he can’t tell which of them are genuine.
“Deadlock. How do we break it? Remember, meanwhile the clock is running. I don’t think Jack’s brain can take the stress on it much longer. Be that as it may, Project Io can’t remain idle for weeks and months without going broke.”
Donovan snapped his fingers. “Got it!” he cried. “We call Jack and get Napoleon into the conversation. We record this. Then Earth will know there’s something rotten in-uh-sorry, Svend.”
Powell frowned. “Well, we can try,” he answered. “But we’d better have something to say he’ll consider worth his notice. “
“Hello, Jack,” he greeted as calmly as he was able. “How are you?”
The barren scene jittered. The belated voice rose and fell. “What…do you want?”
“Why, to continue our conversation. And, to be sure, offer our respects to the Emperor Napoleon. You told us he’ll be listening in. We’d be delighted to have the honor of his participation in our talk. Introductions first. I neglected them earlier. You may recall that my name is Gregory Powell. The gentleman here at my side is Michael Donovan, and behind us you see Captain Svend Borup.” Powell beamed, pointless though he knew it was. “Quite a contrast, we three, eh? Well, humans are a variegated lot. “
After the delay: “That may be. To me you…look similar. I had to exert myself to describe the Emperor Napoleon as closely as I did. Begging your pardon, sir,” Jack said to an unseen observer? His attention returned to Powell. “What do you want? He…he has instructed me…not to waste time on your… importunities. I must prepare…to resist…any invasion.”
“Resist the will of the humans who sent you?” Powell purred. After a minute he saw the moonscape jerk, and went on quickly, hoping the robot would not cut him off, “Our purpose is to show you that we are indeed humans, ourselves, whatever Napoleon may be, and therefore you must, under Code Upsilon, accept that Earth is not endangered and you should resume work. Pay close attention. “
Did a sentient machine afar in space tune himself high as the words reached him?
Powell turned his gaze on Donovan. “Now, Mike,” he said, “I want you to tell me truthfully-truthfully, mind you-that you’re neither a human nor a robot.”
Donovan shivered with eagerness. “I am neither,” he responded. “Now you, Greg, tell me truthfully that you are neither human nor robot. “
“I am neither.” Powell looked straight before him again, into the vision whose eyes he could not see. “Did you hear, Jack? Think about it. The order was to answer the question truthfully. No threat to a human was involved, therefore any robot must obey to the extent possible. However, the single possible answer for him is, ‘I cannot.’ None but a human could disobey and give out the falsehood, ‘I am neither human nor robot.’ “
Wire-tense, the men waited.
Did something whisper unrelayed from the deeps, of did Jack’s own intelligence see the fallacy? The reply took longer than transmission would account for. “That is correct if…if the questioner is human. But if…he is a robot…then another robot can…perfectly well, disobediently, lie-especially if he has been so directed beforehand. The same…holds good for…every such dialogue. It proves nothing. Stop pestering me!”
Powell and Donovan sat mute. “Napoleon, have you any comment?” Borup attempted. Silence answered him.
Jack blanked the screen.
Not even fried herring with potatoes consoled.
The men chewed unspeaking. It was as if they saw, they felt, the immensity and the cold outside this hull. The failure of a venture, the death of many hopes, what were those that the stars were mindful of them?
When Ole at last brought coffee, it revived his master a little. “If Yack is pure crazy, he still has a good logical noodle,” he opined. “You keep after him. Make him t’ink. For instance, would not those viroids make Io have different rocks from what it does?”
Powell shook his head. “No doubt, but what they educated him in was Ionian geology as it is. His job was practical, not scientific. Whenever he noticed anomalies, he was to get on the beam and query the specialists back home. We don’t have time to teach him. Couldn’t you hear how agitated he was?” Powell looked up. “Yes. Each contact has made his condition worse. Unless we can invent a scheme we know will be productive, we’d better quit. Maybe Susan Calvin can generate an idea.”
“That won’t do anything productive for our careers,” Donovan muttered.
“To hell with our careers…But I don’t expect the old lady can solve our problem from her armchair on Earth. Otherwise we wouldn’t have been dispatched. With the kind of transmission delay involved, she couldn’t work her slick robopsych tricks.”
“I s’pose.” Donovan gusted a sigh. “I can’t think how to lure Napoleon into talking to
us, and maybe he doesn’t exist anyway. What say we assume he doesn’t, assume Jack is demented, and try figuring out how to get him to board a ship, or at least keep from sniping at new arrivals? If there’ll ever be any.”
“We’ll give our wits a few days to work, and hope for a script that he won’t see through.”
“I wonder if you can,” Borup said. “I am no expert, but I have known people wit’ strange notions, and they can be very smart, yes, brilliant about defending those notions. They sit in their Plato caves till deat’ comes and kicks them in the behind-”
He broke off. Donovan had smacked fist into palm. Powell drew a whistling breath.
“Hello, Jack.”
The scene was not the base. Rubble lay dark under waxing Jupiter, beneath gashed heights. Volcano fumes lifted dirty white and yellow beyond a ridge. Jack was in the field, readying his caches and strongpoints for war.
The view swayed giddyingly as he straightened. “What do you want now?” It was nearly a shriek. “I told you to leave me alone. I need not listen to you. I can switch off.”
“Just wait. Just wait. “ Until these waves wing out to Napoleon, wherever he is, if he is. “Be calm,” Powell urged. “You’ve demanded positive proof that my companions and I are human. Well, we have it for you. “
Empty time.
“You have tried. What is the certainty? If…you are robots…you are acting under orders. Your… masters…can have foreseen…many…contingencies.”
“Then our masters are human,” Donovan said. “Shouldn’t you hear what they tell you through us?”
He was taking a risk. The suspense was like a slow fire before they heard Jack utter a raw noise. But it was desirable to perturb Napoleon too, if Napoleon was there to be troubled in his own sureness.
“We are human,” Powell said quickly. “You force us, in this emergency, to demonstrate it, no matter what that costs us. Then maybe you ‘II be sorry and obey the surviving member of our party. “
“Remember, if what Napoleon has told you is true,” Donovan joined in-if what Napoleon had been told was true-”we can’t be human. We must be robots, pretending. We must be what he sees on his screen. But if we are human, then Napoleon has told you wrong. Correct?”
Probably Jack never noticed the sweat on the two faces. “Pay close attention,” Powell directed.
Rising, he lifted a detonol stick and brandished it like a sword. Donovan got up too and said, “Greg, I hereby, uh, well, this is the time for you to do what I told you you’d have to do if matters got this desperate. Destroy yourself.”
Powell pulled out the firing pin. It wobbled in his right hand, the stick in his left. “Mike,” he replied, “I order you to destroy yourself.”
Donovan brought his explosive into view and, having yanked the pin free, held the stick dramatically against his throat. The men faced each other. In a proper gravity field their knees might have given way, but here they could somehow keep standing, after a fashion. They breathed hard and raggedly.
“Stop!” Jack’s cry came loud, yet as if from across light-years. “Return those disarmers!”
“If we are robots,” Donovan grated, “why should you care?”
Empty time.
“Third Law! You must!”
“We, we have our orders,” Powell stammered.
Each minute was forever.
At four and a half, Borup entered, halted, stared. “What is this?” he shouted. “Are you crazy too?”
“We have our orders,” Powell repeated.
“I countermand them!” Borup said. “Disarm those stickst”
For an instant it seemed that Donovan wouldn’t manage it, as badly as his hand was shaking. He did, though. Powell’s pin had already snicked home. They sank limply into their chairs and waited.
After a sixth minute, the swaying image of what Jack saw abruptly had another in it, that of a short, stout man in a cocked hat and epauletted greatcoat. The representation was lifeless, practically a caricature-good enough for an unsophisticated robot-and the audio conveyed little of the torment behind the words.
“Masters, masters! Forgive me! I must have been mistaken, deceived-Are you on Himalia? I shall come straight to you and do whatever you want. Hear me, judge me, forgive me!”
Ole was preparing a victory feast. Borup would not tell his passengers what it was. “ A surprise, somet’ing special and delicious,” he averred, “wit’ red cabbage. Meanwhile, we have our akvavit and, yes, a case of beer I keep for emeryencies. Or for celebrations, no?”
Powell and Donovan didn’t accept at once. They were amply elated as they sat before the station communicator and sent their encoded message homeward.
“…yes, he’s here, thoroughly penitent. Still bewildered, of course, poor devil. After all, he was obeying the humans who’d trained him. No, we aren’t leaning on him about them. We’ve given him the impression we agree they were doubtless simply misguided, and once we reach Earth, everything will soon be straightened out. In case Napoleon does get rambunctious en route, well, he’s a little one, and we have two husky crewrobots to keep him in hand.
“No, we haven’t played detective and tried to find out who the guilty parties are. That’s for the police, or for Dr. Calvin. We can’t help making some pretty shrewd guesses.
“Jack will need a bit of therapy. He’s more than willing to go back to work, but he’s been through a nightmare and ought to be restabilized first. Any smart young robopsychologist should be able to come out here and take care of that in short order.
“We look forward to seeing what this sensation will do to the political picture!”
Powell had been talking. He glanced at Donovan. “Okay, pal,” he invited. “Your turn to bask in the glory.”
Donovan beamed, cleared his throat, and began: “The problem was, what could we do that humans could but robots not, under the circumstances?
“Well, uh, suppose we ordered each other to self-destruct. There was no clear reason for that. How could it help our purpose? Jack would still suppose we were play-acting. So if we were both robots, we’d disobey the order.
“If one of us was a robot and the other not, the robot would obey; the human might or might not.
“If we were both human, probably neither of us would obey, but we both could if we chose to.
“We both chose to. At the last instant, Captain Borup came in and countermanded the orders. Now if he were a robot, that wouldn’t have changed the situation. Whether we were robot or human, neither of us was bound to obey him. Therefore, if either or both of us did, he must be human.”
Donovan’s laugh was nervous. “Obviously, we never meant to go all the way, whatever happened. We certainly intended to heed Captain Borup-and sweated that out, I can tell you! But we had to show that this was not mere play-acting.
“Jack might be too stressed to think fast, but if Napoleon was watching, he’d know that a robot can only tell a human to suicide if the robot knows in advance that this is a charade-whether or not the robot’s own suicide is part of the deal. If the human then actually pulls the pin, endangers himself, he’ll have to intervene. Maybe not at once, but in plenty of time to make sure the explosive won’t go off. But the two of us stood tight till the moment was only seconds away and the third man arrived.
“Yes, it was still logically possible that all three of us were robots going through carefully planned motions. However, Jack’s only real experience of other robots had been with his simpleminded workers; Edgar’s crew came, took on cargo, and left. Napoleon’s knowledge of the world, including both humans and robots, had to be equally limited, or the contradictions in the viroid story would have confused him too badly to carry out his task. Neither of them would have believed any robot was capable of this much flexibility; and in fact, very few are. Nothing would ring true unless at least one human was present.
“But then Napoleon’s orders must involve an untruth. Instead of a hypothetical situation where billions of people might die
, he faced a real one where he’d caused a flesh-and-blood human, or maybe three, to be at risk of life. First Law took over.”
Donovan switched off transmission, leaned back, and blew out his cheeks. “Whoo!” he snorted. “I’m wrung dry. Let’s get out of this icebox and go back to the ship for those drinks. We’ve an hour and a half till we need to talk to them yonder.”
Powell laughed. “ And if we don’t feel like official conversation at that moment, just what do they think they can do about it?”
Foundation’s Conscience
by George Zebrowski
My search for Hari Seldon began in 1056 F.E. I had intended a simple assembly of Seldon’s appearances in the Time Vault at the crisis points of the last millennium, with my own commentary added, and had assumed that the research would require nothing more than routine retrievals. I even suspected that such a stringing together of Seldon’s projections already existed, perhaps with another historian’s commentary.
My first surprise, as I searched through Trantor’s memory, was to find that no such compilation existed in the great library. I proceeded to gather the individual manifestations, and was startled to find only three of Seldon’s six appearances.
At first I thought that I had simply failed to enter the retrieval codes correctly; but after repeated runs it became clear that three of the six appearances were not there. I concluded that they had to be in the general bank somewhere, requiring a long search, which I undertook -as much in a fit of pique as out of curiosity about the great psychohistorian’s ideas. I would locate, compile, and present in usable form all of Hari Seldon’s manifestations. I was good at search programs (colleagues of mine claimed that this was all I had ever been good at, though they were polite enough when they needed my skills). It was unthinkable that anything of Hari Seldon’s remains could have actually been lost, but I would make certain of that, if nothing else; even ascertaining such a fact would give me a place in the upcoming 117th edition of the Encyclopedia Galactica.
