Chapter 12.


Elijah Baley looked up as Commissioner Julius Enderby entered the office. He nodded wearily.

The Commissioner looked at the clock and grunted, Dont tell me youve been here all night!

Baley said, I wont.

The Commissioner said in a low voice, Any trouble last night? Baley shook his head.

The Commissioner said, Ive been thinking that I could be minimizing the possibility of riots. If theres anything to

Baley said tightly, For Gods sake, Commissioner, if anything happened, Id tell you. There was no trouble of any sort.

All right. The Commissioner moved away, passing beyond the door that marked off the unusual privacy that became his exalted position.

Baley looked after him and thought: He must have slept last night.

Baley bent to the routine report he was trying to write as a cover-up for the real activities of the last two days, but the words he had tapped out by finger touch blurred and danced. Slowly, he became aware of an object standing by his desk.

He lifted his head. What do you want?

It was R. Sammy. Baley thought: Juliuss private flunky. It pays to be a Commissioner.

R. Sammy said through his fatuous grin, The Commissioner wants to see you, Lije. He says right away.

Baley waved his hand. He just saw me. Tell him Ill be in later.

R. Sammy said, He says right away.

All right. All right. Go away.

The robot backed away, saying, The Commissioner wants to see you right away, Lije. He says right away.

Jehoshaphat, said Baley between his teeth. Im going. Im going. He got up from his desk, headed for the office, and R. Sammy was silent.

Baley said as he entered, Damn it, Commissioner, dont send that thing after me, will you?

But the Commissioner only said, Sit down, Lije. Sit down. Baley sat down and stared. Perhaps he had done old Julius an injustice. Perhaps the man hadnt slept after all. He looked fairly beat.

The Commissioner was tapping the paper before him. Theres a record of a call you made to a Dr. Gerrigel at Washington by insulated beam.

Thats right, Commissioner.

Theres no record of the conversation, naturally, since it was insulated. Whats it all about?

Im after background information.

Hes a roboticist, isnt he?

Thats right.

The Commissioner put out a lower lip and suddenly looked like a child about to pout. But whats the point? What kind of information are you after?

Im not sure, Commissioner. I just have a feeling that in a case like this, information on robots might help. Baley clamped his mouth shut after that. He wasnt going to be specific, and that was that.

I wouldnt, Lije. I wouldnt. I dont think its wise.

Whats your objection, Commissioner?

The fewer the people who know about all this, the better.

Ill tell him as little as I can. Naturally.

I still dont think its wise.

Baley was feeling just sufficiently wretched to lose patience.

He said, Are you ordering me not to see him?

No. No. You do as you see fit. Youre heading this investigation. Only

Only what?

The Commissioner shook his head. Nothing.Where is he? You know who I mean.

Baley did. He said, Daneels still at the files.

The Commissioner paused a long moment, then said, Were not making much progress, you know.

Were not making any so far. Still, things may change.

All right, then, said the Commissioner, but he didnt look as though he really thought it were all right.

R. Daneel was at Baleys desk, when the latter returned.

Well, and what have you got? Baley asked gruffly.

I have completed my first, rather hasty, search through the files, partner Elijah, and I have located two of the people who tried to track us last night and who, moreover, were at the shoe store during the former incident.

Lets see.

R. Daneel placed the small, stamp-size cards before Baley. They were mottled with the small dots that served as code. The robot also produced a portable decoder and placed one of the cards into an appropriate slot. The dots possessed electrical conduction properties different from that of the card as a whole. The electric field passing through the card was therefore distorted in a highly specific manner and in response to that specification the three-by-six screen above the decoder was filled with words. Words which, uncoded, would have filled several sheets of standard size report paper. Words, moreover, which could not possibly be interpreted by anyone not in possession of an official police decoder.

Baley read through the material stolidly. The first person was Francis Clousarr, age thirty-three at time of arrest two years before; cause of arrest, inciting to riot; employee at New York Yeast; home address, so-and-so; parentage, so-and-so; hair, eyes, distinguishing marks, educational history, employment history, psychoanalytic profile, physical profile, data here, data there, and finally reference to a photo in the rogues gallery.

You checked the photograph? asked Baley. Yes, Elijah.

The second person was Gerhard Paul. Baley glanced at the material on that card and said, This is all no good.

R. Daneel said, I am sure that cannot be so. If there is an organization of Earthmen who are capable of the crime we are investigating, these are members. Is that not an obvious likelihood? Should they then not be questioned?

Wed get nothing out of them.

They were there, both at the shoe store and in the kitchen. They cannot deny it.

Just being theres no crime. Besides which, they can deny it. They can just say they werent there. Its as simple as that. How can we prove theyre lying?

I saw them.

Thats no proof, said Baley, savagely. No court, if it ever came to that, would believe that you could remember two faces in a blur of a million.

It is obvious that I can.

Sure. Tell them what you are. As soon as you do that, youre no witness. Your kind have no status in any court of law on Earth.

R. Daneel said, I take it, then, that you have changed your mind.

What do you mean?

Yesterday, in the kitchen, you said there was no need to arrest them. You said that as long as I remembered their faces, we could arrest them at any time.

Well, I didnt think it through, said Baley. I was crazy. It cant be done.

Not even for psychological reasons? They would not know we had no legal proof of their complicity in conspiracy.

Baley said, tensely, Look, I am expecting Dr. Gerrigel of Washington in half an hour. Do you mind waiting till hes been here and gone? Do you mind?

I will wait, said R. Daneel.

Anthony Gerrigel was a precise and very polite man of middle height, who looked far from being one of the most erudite roboticists on Earth. He was nearly twenty minutes late, it turned out, and quite apologetic about it. Baley, white with an anger born of apprehension, shrugged off the apologies gracelessly. He checked his reservation on Conference Room D, repeated his instructions that they were not to be disturbed on any account for an hour, and led Dr. Gerrigel and R. Daneel down the corridor, up a ramp, and through a door that led to one of the spy-beam-insulated chambers.

Baley checked the walls carefully before sitting down, listening to the soft burr of the pulsometer in his hand, waiting for any fading of the steady sound which would indicate a break, even a small one, in the insulation. He turned it on the ceiling, floor, and, with particular care, on the door. There was no break.

Dr. Gerrigel smiled a little. He looked like a man who never smiled more than a little. He was dressed with a neatness that could only be described as fussy. His iron-gray hair was smoothed carefully back and his face looked pink and freshly washed. He sat with a posture of prim stiffness as though repeated maternal advice in his younger years concerning the desirability of good posture had rigidified his spine forever.

He said to Baley, You make this all seem very formidable.

Its quite important, Doctor. I need information about robots that only you can give me, perhaps. Anything we say here, of course, is top secret and the City will expect you to forget it all when you leave. Baley looked at his watch.

The little smile on the roboticists face winked away. He said, Let me explain why I am late. The matter obviously weighed upon him. I decided not to go by air. I get airsick.

Thats too bad, said Baley. He put away the pulsometer, after checking its standard settings to make last-minute certain that there was nothing wrong with it, and sat down.

Or at least not exactly airsick, but nervous. A mild agoraphobia. Its nothing particularly abnormal, but there it is. So I took the expressways.

Baley felt a sudden sharp interest. Agoraphobia?

I make it sound worse than it is, the roboticist said at once. Its just the feeling you get in a plane. Have you ever been in one, Mr. Baley?

Several times.

Then you must know what I mean. Its that feeling of being surrounded by nothing; of being separated fromfrom empty air by a mere inch of metal. Its very uncomfortable.

So you took the expressway?


All the way from Washington to New York?

Oh, Ive done it before. Since they built the Baltimore-Philadelphia tunnel, its quite simple.

So it was. Baley had never made the trip himself, but he was perfectly aware that it was possible. Washington, Baltimore, Philadelphia, and New York had grown, in the last two centuries, to the point where all nearly touched. The Four-City Area was almost the official name for the entire stretch of coast, and there were a considerable number of people who favored administrational consolidation and the formation of a single super-City. Baley disagreed with that, himself. New York City by itself was almost too large to be handled by a centralized government. A larger City, with over fifty million population, would break down under its own weight.

The trouble was, Dr. Gerrigel was saying, that I missed a connection in Chester Sector, Philadelphia, and lost time. That, and a little difficulty in getting a transient room assignment, ended by making me late.

Dont worry about that, Doctor. What you say, though, is interesting. In view of your dislike for planes, what would you say to going outside City limits on foot, Dr. Gerrigel?

For what reason? He looked startled and more than a little apprehensive.

Its just a rhetorical question. Im not suggesting that you really should. I want to know how the notion strikes you, thats all.

It strikes me very unpleasantly.

Suppose you had to leave the City at night and walk cross country for half a mile or more.

II dont think I could be persuaded to.

No matter how important the necessity?

If it were to save my life or the lives of my family, I might try. He looked embarrassed. May I ask the point of these questions, Mr. Baley?

Ill tell you. A serious crime has been committed, a particularly disturbing murder. Im not at liberty to give you the details. There is a theory, however, that the murderer, in order to commit the crime, did just what we were discussing; he crossed open country at night and alone. I was just wondering what kind of man could do that.

Dr. Gerrigel shuddered. No one I know. Certainly not I. Of course, among millions I suppose you could find a few hardy individuals.

But you wouldnt say it was a very likely thing for a human being to do?

No. Certainly not likely.

In fact, if theres any other explanation for the crime, any other conceivable explanation, it should be considered.

Dr. Gerrigel looked more uncomfortable than ever as he sat bolt upright with his well-kept hands precisely folded in his lap. Do you have an alternate explanation in mind?

Yes. It occurs to me that a robot, for instance, would have no difficulty at all in crossing open country.

Dr. Gerrigel stood up. Oh, my dear sir!

Whats wrong?

You mean a robot may have committed the crime?

Why not?

Murder? Of a human being?

Yes. Please sit down, Doctor.

The roboticist did as he was told. He said, Mr. Baley, there are two acts involved: walking cross country, and murder. A human being could commit the latter easily, but would find difficulty in doing the former. A robot could do the former easily, but the latter act would be completely impossible. If youre going to replace an unlikely theory by an impossible one

Impossible is a hell of a strong word, Doctor.

Youve heard of the First Law of Robotics, Mr. Baley?

Sure. I can even quote it: A robot may not injure a human being, or, through inaction, allow a human being to come to harm. Baley suddenly pointed a finger at the roboticist and went on, Why cant a robot be built without the First Law? Whats so sacred about it?

Dr. Gerrigel looked startled, then tittered, Oh, Mr. Baley.

Well, whats the answer?

Surely, Mr. Baley, if you even know a little about robotics, you must know the gigantic task involved, both mathematically and electronically, in building a positronic brain.

I have an idea, said Baley. He remembered well his visit to a robot factory once in the way of business. He had seen their library of book-films, long ones, each of which contained the mathematical analysis of a single type of positronic brain. It took more than an hour for the average such film to be viewed at standard scanning speed, condensed though its symbolisms were. And no two brains were alike, even when prepared according to the most rigid specifications. That, Baley understood, was a consequence of Heisenbergs Uncertainty Principle. This meant that each film had to be supplemented by appendices involving possible variations.

Oh, it was a job, all right. Baley wouldnt deny that.

Dr. Gerrigel said, Well, then, you must understand that a design for a new type of positronic brain, even one where only minor innovations are involved, is not the matter of a nights work. It usually involves the entire research staff of a moderately sized factory and takes anywhere up to a year of time. Even this large expenditure of work would not be nearly enough if it were not that the basic theory of such circuits has already been standardized and may be used as a foundation for further elaboration. The standard basic theory involves the Three Laws of Robotics: the First Law, which youve quoted; the Second Law, which states, A robot must obey the orders given it by human beings except where such orders would conflict with the First Law, and the Third Law, which states, A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. Do you understand?

R. Daneel, who, to all appearances, had been following the conversation with close attention, broke in. If you will excuse me, Elijah, I would like to see if I follow Dr. Gerrigel. What you imply, sir, is that any attempt to build a robot, the working of whose positronic brain is not oriented about the Three Laws, would require first the setting up of a new basic theory and that this, in turn, would take many years.

The roboticist looked very gratified. That is exactly what I mean.

Mr. Baley waited a moment, then carefully introduced R. Daneel: This is Daneel Olivaw, Dr. Gerrigel.

Good day, Mr. Olivaw. Dr. Gerrigel extended his hand and shook Daneels. He went on, It is my estimation that it would take fifty years to develop the basic theory of a non-Asenion positronic brainthat is, one in which the basic assumptions of the Three Laws are disallowedand bring it to the point where robots similar to modern models could be constructed.

And this has never been done? asked Baley. I mean, Doctor, that weve been building robots for several thousand years. In all that time, hasnt anybody or any group had fifty years to spare?

Certainly, said the roboticist, but it is not the sort of work that anyone would care to do.

I find that hard to believe. Human curiosity will undertake anything.

It hasnt undertaken the non-Asenion robot. The human race, Mr. Baley, has a strong Frankenstein complex.

A what?

Thats a popular name derived from a Medieval novel describing a robot that turned on its creator. I never read the novel myself. But thats beside the point. What I wish to say is that robots without the First Law are simply not built.

And no theory for it even exists?

Not to my knowledge, and my knowledge, he smiled self-consciously, is rather extensive.

And a robot with a First Law built in could not kill a man?

Never. Unless such killing were completely accidental or unless it were necessary to save the lives of two or more men. In either case, the positronic potential built up would ruin the brain past recovery.

All right, said Baley. All this represents the situation on Earth. Right?

Yes. Certainly.

What about the Outer Worlds?

Some of Dr. Gerrigels self-assurance seemed to ooze away. Oh dear, Mr. Baley, I couldnt say of my own knowledge, but Im sure that if non-Asenion positronic brains were ever designed or if the mathematical theory were worked out, wed hear of it.

Would we? Well, let me follow up another thought in my mind, Dr. Gerrigel. I hope you dont mind.

No. Not at all. He looked helplessly first at Baley, then at R. Daneel. After all, if it is as important as you say, Im glad to do all I can.

Thank you, Doctor. My question is, why humanoid robots? I mean that Ive been taking them for granted all my life, but now it occurs to me that I dont know the reason for their existence. Why should a robot have a head and four limbs? Why should he look more or less like a man?

You mean, why shouldnt he be built functionally, like any other machine?

Right, said Baley. Why not?

Dr. Gerrigel smiled a little. Really, Mr. Baley, you are born too late. The early literature of robotics is riddled with a discussion of that very matter and the polemics involved were something frightful. If you would like a very good reference to the disputations among the functionalists and anti-functionalists, I can recommend Hanfords History of Robotics. Mathematics is kept to a minimum. I think youd find it very interesting.

Ill look it up, said Baley, patiently. Meanwhile, could you give me an idea?

The decision was made on the basis of economics. Look here, Mr. Baley, if you were supervising a farm, would you care to buy a tractor with a positronic brain, a reaper, a harrow, a milker, an automobile, and so on, each with a positronic brain; or would you rather have ordinary unbrained machinery with a single positronic robot to run them all. I warn you that the second alternative represents only a fiftieth or a hundredth the expense.

But why the human form?

Because the human form is the most successful generalized form in all nature. We are not a specialized animal, Mr. Baley, except for our nervous systems and a few odd items. If you want a design capable of doing a great many widely various things, all fairly well, you could do no better than to imitate the human form. Besides that, our entire technology is based on the human form. An automobile, for instance, has its controls so made as to be grasped and manipulated most easily by human hands and feet of a certain size and shape, attached to the body by limbs of a certain length and joints of a certain type. Even such simple objects as chairs and tables or knives and forks are designed to meet the requirements of human measurements and manner of working. It is easier to have robots imitate the human shape than to redesign radically the very philosophy of our tools.

I see. That makes sense. Now isnt it true, Doctor, that the roboticists of the Outer World manufacture robots that are much more humanoid than our Own?

I believe that is true.

Could they manufacture a robot so humanoid that it would pass for human under ordinary conditions?

Dr. Gerrigel lifted his eyebrows and considered that. I think they could, Mr. Baley. It would be terribly expensive. I doubt that the return could be profitable.

Do you suppose, went on Baley, relentlessly, that they could make a robot that would fool you into thinking it was human?

The roboticist tittered. Oh, my dear Mr. Baley. I doubt that. Really. Theres more to a robot than just his appear

Dr. Gerrigel froze in the middle of the word. Slowly, he turned to R. Daneel, and his pink face went very pale.

Oh, dear me, he whispered. Oh, dear me.

He reached out one hand and touched R. Daneels cheek gingerly. R. Daneel did not move away but gazed at the roboticist calmly.

Dear me, said Dr. Gerrigel, with what was almost a sob in his voice, you are a robot.

It took you a long time to realize that, said Baley, dryly.

I wasnt expecting it. I never saw one like this. Outer World manufacture?

Yes, said Baley.

Its obvious now. The way he holds himself. The manner of his speaking. It is not a perfect imitation, Mr. Baley.

Its pretty good though, isnt it?

Oh, its marvelous. I doubt that anyone could recognize the imposture at sight. I am very grateful to you for having me brought face to face with him. May I examine him? The roboticist was on his feet, eager.

Baley put out a hand. Please, Doctor. In a moment. First, the matter of the murder, you know.

Is that real, then? Dr. Gerrigel was bitterly disappointed and showed it. I thought perhaps that was just a device to keep my mind engaged and to see how long I could be fooled by

It is not a device, Dr. Gerrigel. Tell me, now, in constructing a robot as humanoid as this one, with the deliberate purpose of having it pass as human, is it not necessary to make its brain possess properties as close to that of the human brain as possible?


Very well. Could not such a humanoid brain lack the First Law? Perhaps it is left out accidentally. You say the theory is unknown. The very fact that it is unknown means that the constructors might set up a brain without the First Law. They would not know what to avoid.

Dr. Gerrigel was shaking his head vigorously. No. No. Impossible.

Are you sure? We can test the Second Law, of course.Daneel, let me have your blaster.

Baleys eyes never left the robot. His own hand, well to one side, gripped his own blaster tightly.

R. Daneel said calmly, Here it is, Elijah, and held it out, butt first.

Baley said, A plain-clothes man must never abandon his blaster, but a robot has no choice but to obey a human.

Except, Mr. Baley, said Dr. Gerrigel, when obedience involves breaking the First Law.

Do you know, Doctor, that Daneel drew his blaster on an unarmed group of men and women and threatened to shoot?

But I did not shoot, said R. Daneel.

Granted, but the threat was unusual in itself, wasnt it, Doctor? Dr. Gerrigel bit his lip. Id need to know the exact circumstances to judge. It sounds unusual.

Consider this, then. R. Daneel was on the scene at the time of the murder, and if you omit the possibility of an Earthman having moved across open country, carrying a weapon with him, Daneel and Daneel alone of all the persons on the scene could have hidden the weapon.

Hidden the weapon? asked Dr. Gerrigel.

Let me explain. The blaster that did the killing was not found. The scene of the murder was searched minutely and it was not found. Yet it could not have vanished like smoke. There is only one place it could have been, only one place they would not have thought to look.

Where, Elijah? asked R. Daneel.

Baley brought his blaster into view, held its barrel firmly in the robots direction.

In your food sac, he said. In your food sac, Daneel!
