I, Robot Read online

  "Really?" Francis Quinn allowed himself a trace of sarcasm. "And if one were, accidentally, of course, not destroyed – and there happened to be a humanoid structure waiting for a brain."

  "Impossible!"

  "You would have to prove that to the government and the public, so why not prove it to me now."

  "But what could our purpose be?" demanded Lanning in exasperation. "Where is our motivation? Credit us with a minimum of sense."

  "My dear sir, please. The Corporation would be only too glad to have the various Regions permit the use of humanoid positronic robots on inhabited worlds. The profits would be enormous. But the prejudice of the public against such a practice is too great. Suppose you get them used to such robots first – see, we have a skillful lawyer, a good mayor,and he is a robot. Won't you buy our robot butlers?"

  "Thoroughly fantastic. An almost humorous descent to the ridiculous."

  "I imagine so. Why not prove it? Or would you still rather try to prove it to the public?"

  The light in the office was dimming, but it was not yet too dim to obscure the flush of frustration on Alfred Lanning's face. Slowly, the roboticist's finger touched a knob and the wall illuminators glowed to gentle life.

  "Well, then," he growled, "let us see."

  The face of Stephen Byerley is not an easy one to describe. He was forty by birth certificate and forty by appearance – but it was a healthy, well-nourished good-natured appearance of forty; one that automatically drew the teeth of the bromide about "looking one's age."

  This was particularly true when he laughed, and he was laughing now. It came loudly and continuously, died away for a bit, then began again-

  And Alfred Lanning's face contracted into a rigidly bitter monument of disapproval. He made a half gesture to the woman who sat beside him, but her thin, bloodless lips merely pursed themselves a trifle.

  Byerley gasped himself a stage nearer normality.

  "Really, Dr. Lanning… really- I… I… a robot?"

  Lanning bit his words off with a snap, "It is no statement of mine, sir. I would be quite satisfied to have you a member of humanity. Since our corporation never manufactured you, I am quite certain that you are – in a legalistic sense, at any rate. But since the contention that you are a robot has been advanced to us seriously by a man of certain standing-"

  "Don't mention his name, if it would knock a chip off your granite block of ethics, but let's pretend it was Frank Quinn, for the sake of argument, and continue."

  Lanning drew in a sharp, cutting snort at the interruption, and paused ferociously before continuing with added frigidity, "-by a man of certain standing, with whose identity I am not interested in playing guessing games, I am bound to ask your cooperation in disproving it. The mere fact that such a contention could be advanced and publicized by the means at this man's disposal would be a bad blow to the company I represent – even if the charge were never proven. You understand me?"

  "Oh, yes, your position is clear to me. The charge itself is ridiculous. The spot you find yourself in is not. I beg your pardon, if my laughter offended you. It was the first I laughed at, not the second. How can I help you?"

  "It could be very simple. You have only to sit down to a meal at a restaurant in the presence of witnesses, have your picture taken, and eat." Lanning sat back in his chair, the worst of the interview over. The woman beside him watched Byerley with an apparently absorbed expression but contributed nothing of her own.

  Stephen Byerley met her eyes for an instant, was caught by them, then turned back to the roboticist. For a while his fingers were thoughtful over the bronze paper-weight that was the only ornament on his desk.

  He said quietly, "I don't think I can oblige you."

  He raised his hand, "Now wait, Dr. Lanning. I appreciate the fact that this whole matter is distasteful to you, that you have been forced into it against your will, that you feel you are playing an undignified and even ridiculous part. Still, the matter is even more intimately concerned with myself, so be tolerant.

  "First, what makes you think that Quinn -this man of certain standing, you know- wasn't hoodwinking you, in order to get you to do exactly what you are doing?"

  "Why it seems scarcely likely that a reputable person would endanger himself in so ridiculous a fashion, if he weren't convinced he were on safe ground."

  There was little humor in Byerley's eyes, "You don't know Quinn. He could manage to make safe ground out of a ledge a mountain sheep could not handle. I suppose be showed the particulars of the investigation he claims to have made of me?"

  "Enough to convince me that it would be too troublesome to have our corporation attempt to disprove them when you could do so more easily."

  "Then you believe him when he says I never eat. You are a scientist, Dr. Lanning. Think of the logic required. I have not been observed to eat, therefore, I never eat Q.E.D. After all!"

  "You are using prosecution tactics to confuse what is really a very simple situation."

  "On the contrary, I am trying to clarify what you and Quinn between you are making a very complicated one. You see, I don't sleep much, that's true, and I certainly don't sleep in public. I have never cared to eat with others – an idiosyncrasy which is unusual and probably neurotic in character, but which harms no one. Look, Dr. Lanning, let me present you with a suppositious case. Supposing we had a politician who was interested in defeating a reform candidate at any cost and while investigating his private life came across oddities such as I have just mentioned.

  "Suppose further that in order to smear the candidate effectively, he comes to your company as the ideal agent. Do you expect him to say to you, 'So-and-so is a robot because he hardly ever eats with people, and I have never seen him fall asleep in the middle of a case; and once when I peeped into his window in the middle of the night, there he was, sitting up with a book; and I looked in his frigidaire and there was no food in it.'

  "If he told you that, you would send for a straitjacket. But if he tells you, 'He never sleeps; he never eats,' then the shock of the statement blinds you to the fact that such statements are impossible to prove. You play into his hands by contributing to the to-do."

  "Regardless, sir," began Lanning, with a threatening obstinacy, "of whether you consider this matter serious or not, it will require only the meal I mentioned to end it."

  Again Byerley turned to the woman, who still regarded him expressionlessly. "Pardon me. I've caught your name correctly, haven't I? Dr. Susan Calvin?"

  "Yes, Mr. Byerley."

  "You're the U. S. Robot's psychologist, aren't you?"

  "Robopsychologist, please."

  "Oh, are robots so different from men, mentally?"

  "Worlds different." She allowed herself a frosty smile, "Robots are essentially decent."

  Humor tugged at the corners of the lawyer's mouth, "Well, that's a hard blow. But what I wanted to say was this. Since you're a psycho- a robopsychologist, and a woman, I'll bet that you've done something that Dr. Lanning hasn't thought of."

  "And what is that?"

  "You've got something to eat in your purse."

  Something caught in the schooled indifference of Susan Calvin's eyes. She said, "You surprise me, Mr. Byerley."

  And opening her purse, she produced an apple. Quietly, she handed it to him. Dr. Lanning, after an initial start, followed the slow movement from one hand to the other with sharply alert eyes.

  Calmly, Stephen Byerley bit into it, and calmly he swallowed it

  "You see, Dr. Lanning?"

  Dr. Lanning smiled in a relief tangible enough to make even his eyebrows appear benevolent A relief that survived for one fragile second.

  Susan Calvin said, "I was curious to see if you would eat it, but, of course, in the present case, it proves nothing."

  Byerley grinned, "It doesn't?"

  "Of course not. It is obvious, Dr. Lanning, that if this man were a humanoid robot, he would be a perfect imitation. He is almost too human to be credible. Aft
er all, we have been seeing and observing human beings all our lives; it would be impossible to palm something merely nearly right off on us. It would have to be all right. Observe the texture of the skin, the quality of the irises, the bone formation of the hand. If he's a robot, I wish U. S. Robots had made him, because he's a good job. Do you suppose then, that anyone capable of paying attention to such niceties would neglect a few gadgets to take care of such things as eating, sleeping, elimination? For emergency use only, perhaps; as, for instance, to prevent such situations as are arising here. So a meal won't really prove anything."

  "Now wait," snarled Lanning, "I am – not quite the fool both of you make me out to be. I am not interested in the problem of Mr. Byerley's humanity or nonhumanity. I am interest in getting the corporation out of a hole. A public meal will end the matter and keep it ended no matter what Quinn does. We can leave the finer details to lawyers and robopsychologists."

  "But, Dr. Lanning," said Byerley, "you forget the politics of the situation. I am as anxious to be elected as Quinn is to stop me. By the way, did you notice that you used his name? It's a cheap shyster trick of mine; I knew you would, before you were through."

  Lanning flushed, "What has the election to do with it?"

  "Publicity works both ways, sir. If Quinn wants to call me a robot, and has the nerve to do so, I have the nerve to play the game his way."

  "You mean you-" Lanning was quite frankly appalled.

  "Exactly. I mean that I'm going to let him go ahead, choose his rope, test its strength, cut off the right length, tie the noose, insert his head and grin. I can do what little else is required."

  "You are mighty confident."

  Susan Calvin rose to her feet, "Come, Alfred, we won't change his mind for him."

  "You see." Byerley smiled gently. "You're a human psychologist, too."

  But perhaps not all the confidence that Dr. Lanning had remarked upon was present that evening when Byerley's car parked on the automatic treads leading to the sunken garage,

  and Byerley himself crossed the path to the front door of his house.

  The figure in the wheel chair looked up as he entered and smiled. Byerley's face lit with affection. He crossed over to it.

  The cripple's voice was a hoarse, grating whisper that came out of a mouth forever twisted to one side, leering out of a face that was half scar tissue, "You're late, Steve."

  "I know, John, I know. But I've been up against a peculiar and interesting trouble today."

  "So?" Neither the torn face nor the destroyed voice could carry expression but there was anxiety in the clear eyes. "Nothing you can't handle?"

  "I'm not exactly certain. I may need your help. You're the brilliant one in the family. Do you want me to take you out into the garden? It's a beautiful evening."

  Two strong arms lifted John from the wheel chair. Gently, almost caressingly, Byerley's arms went around the shoulders and under the swathed legs of the cripple. Carefully, and slowly, he walked through the rooms, down the gentle ramp that had been built with a wheel chair in mind, and out the back door into the walled and wired garden behind the house.

  "Why don't you let me use the wheel chair, Steve? This is Silly."

  "Because I'd rather carry you. Do you object? You know that you're as glad to get out of that motorized buggy for a while as I am to see you out. How do you feel today?" He deposited John with infinite care upon the cool grass.

  "How should I feel? But tell me about your troubles."

  "Quinn's campaign will be based on the fact that he claims I'm a robot."

  John's eyes opened wide, "How do you know? It's impossible. I won't believe it."

  "Oh, come, I tell you it's so. He had one of the big-shot scientists of U. S. Robot amp; Mechanical Men Corporation over at the office to argue with me."

  Slowly John's hands tore at the grass, "I see. I see."

  Byerley said, "But we can let him choose his ground. I have an idea. Listen to me and tell me if we can do it "

  The scene as it appeared in Alfred Lanning's office that night was a tableau of stares. Francis Quinn stared meditatively at Alfred Lanning. Lanning's stare was savagely set upon Susan Calvin, who stared impassively in her turn at Quinn.

  Francis Quinn broke it with a heavy attempt at lightness, "Bluff. He's making it up as he goes along."

  "Are you going to gamble on that, Mr. Quinn?" asked Dr. Calvin, indifferently.

  "Well, it's your gamble, really."

  "Look here," Lanning covered definite pessimism with bluster, "we've done what you asked. We witnessed the man eat. It's ridiculous to presume him a robot."

  "Do you think so?" Quinn shot toward Calvin. "Lanning said you were the expert."

  Lanning was almost threatening, "Now, Susan-"

  Quinn interrupted smoothly, "Why not let her talk, man? She's been sitting there imitating a gatepost for half an hour."

  Lanning felt definitely harassed. From what he experienced then to incipient paranoia was but a step. He said, "Very well. Have your say, Susan. We won't interrupt you."

  Susan Calvin glanced at him humorlessly, then fixed cold eyes on Mr. Quinn. "There are only two ways of definitely proving Byerley to be a robot, sir. So far you are presenting circumstantial evidence, with which you can accuse, but not prove – and I think Mr. Byerley is sufficiently clever to counter that sort of material. You probably think so yourself, or you wouldn't have come here.

  "The two methods of proof are the physical and the psychological. Physically, you can dissect him or use an X-ray. How to do that would be your problem. Psychologically, his behavior can be studied, for if he is a positronic robot, he must conform to the three Rules of Robotics. A positronic brain can not be constructed without them. You know the Rules, Mr. Quinn?"

  She spoke them carefully, clearly, quoting word for word the famous bold print on page one of the "Handbook of Robotics."

  "I've heard of them," said Quinn, carelessly.

  "Then the matter is easy to follow," responded the psychologist, dryly. "If Mr. Byerley breaks any of those three rules, he is not a robot. Unfortunately, this procedure works in only one direction. If he lives up to the rules, it proves nothing one way or the other."

  Quinn raised polite eyebrows, "Why not, doctor?"

  "Because, if you stop to think of it, the three Rules of Robotics are the essential guiding principles of a good many of the world's ethical systems. Of course, every human being is supposed to have the instinct of self-preservation. That's Rule Three to a robot. Also every 'good' human being, with a social conscience and a sense of responsibility, is supposed to defer to proper authority; to listen to his doctor, his boss, his government, his psychiatrist, his fellow man; to obey laws, to follow rules, to conform to custom – even when they interfere with his comfort or his safety. That's Rule Two to a robot. Also, every 'good' human being is supposed to love others as himself, protect his fellow man, risk his life to save another. That's Rule One to a robot. To put it simply – if Byerley follows all the Rules of Robotics, he may be a robot, and may simply be a very good man."

  "But," said Quinn, "you're telling me that you can never prove him a robot."

  "I may be able to prove him not a robot"

  "That's not the proof I want."

  "You'll have such proof as exists. You are the only one responsible for your own wants."

  Here Lanning's mind leaped suddenly to the sting of an idea, "Has it occurred to anyone," he ground out, "that district attorney is a rather strange occupation for a robot? The prosecution of human beings – sentencing them to death – bringing about their infinite harm-"

  Quinn grew suddenly keen, "No, you can't get out of it that way. Being district attorney doesn't make him human. Don't you know his record? Don't you know that he boasts that he has never prosecuted an innocent man; that there are scores of people left untried because the evidence against them didn't satisfy him, even though he could probably have argued a jury into atomizing them? That happens to be s
o."

  Tanning's thin cheeks quivered, "No, Quinn, no. There is nothing in the Rules of Robotics that makes any allowance for human guilt. A robot may not judge whether a human being deserves death. It is not for him to decide. He may not harm a human-variety skunk, or variety angel."

  Susan Calvin sounded tired. "Alfred," she said, "don't talk foolishly. What if a robot came upon a madman about to set fire to a house with people in it He would stop the madman, wouldn't he?"

  "Of course."

  "And if the only way he could stop him was to kill him-"

  There was a faint sound in Lanning's throat. Nothing more.

  "The answer to that, Alfred, is that he would do his best not to kill him. If the madman died, the robot would require psychotherapy because he might easily go mad at the conflict presented him -of having broken Rule One to adhere to Rule One in a higher sense. But a man would be dead and a robot would have killed him."

  "Well, is Byerley mad?" demanded Lanning, with all the sarcasm he could muster.

  "No, but he has killed no man himself. He has exposed facts which might represent a particular human being to be dangerous to the large mass of other human beings we call society. He protects the greater number and thus adheres to Rule One at maximum potential. That is as far as he goes. It is the judge who then condemns the criminal to death or imprisonment, after the jury decides on his guilt or innocence. It is the jailer who imprisons him, the executioner who kills him. And Mr. Byerley has done nothing but determine truth and aid society.

  "As a matter of fact, Mr. Quinn, I have looked into Mr. Byerley's career since you first brought this matter to our attention. I find that he has never demanded the death sentence in his closing speeches to the jury. I also find that he has spoken on behalf of the abolition of capital punishment and contributed generously to research institutions engaged in criminal neurophysiology. He apparently believes in the cure, rather than the punishment of crime. I find that significant."

  "You do?" Quinn smiled. "Significant of a certain odor of roboticity, perhaps?"

  "Perhaps. Why deny it? Actions such as his could come only from a robot, or from a very honorable and decent human being. But you see, you just can't differentiate between a robot and the very best of humans."
