"I'll give you the money, you cheapskate! Listen, what do you need with the Nobel Prize?" My double narrowed his eyes. "If the computer-womb can easily make people, then money ..." "... is easier than anything! With the right paper and all the water marks ... well, why not?" "We'll each buy a three-bedroom co-op," my double said, leaning back against the wall dreamily. "And a Volga car..." "And two dachas each: one in the Crimea for rest and one on the Riga seacoast for respectability." "And we'll make a few more of us. One will work so that public outcry will be stifled ..." "... and the others will be parasites to their heart's content..." "... with a guaranteed alibi. Why not?" We stopped and looked at each other in disgust. "God, what depressing small-timers we are!" I grabbed my head. "We take a major discovery and try it on for size on stupid stuff: a dissertation, a prize, a dacha, beating people up with alibis... This is a Method of Synthesizing Man! And we're...." "It's all right, it happens. Every person has petty thoughts once in a while. The important thing is to keep them from turning into petty acts." "Actually, so far I see only one positive application of the discovery: you can see your faults much better when they're in someone else." "Yes, but is that any reason for doubling the earth's population?" We were sitting opposite each other in our underwear. I was reflected in him, a mirror image. "All right, let's get serious. What do we want?" "And what can we do?" "And what do we understand about this business?" "Let's begin with what's what. The ideas of Sechyonov, Pavlov, Weiner, and Ashby agreed on one point: that the brain is a machine. Petruccio's experiments on controlling the development of a human fetus is another move in this direction. The striving for greater complexity and universality in technological systems-just take the desire of microelectricians to create machines that are as complex as the human brain!" "In other words-our discovery is no accident. The way was prepared for it by the development of ideas and technology. If not this way, then another; if not now, then in a few years or decades; if not us, then someone else would discover it. Therefore, the question comes down to ..." ". . . what can we and must we do in that period-maybe a year, maybe decades, no one knows, but it's better to take the shorter time-that we have as a head start on the others." "Yes." "How is it usually done?" My double rested his cheek on his hand. "An engineer has the desire to create something lasting. He looks for a client. Or the client looks for him, depending on who needs whom more. The client gives him a technological problem: 'Use your ideas and your knowledge to create such and such. It must have the following parameters and withstand the following ... and it should guarantee the production annually of no less than such-and-such percent. The amount is, and the time allotted is. The sanctions follow general usage....' A contract is signed and then it is done. We have an idea and we want to develop it further. But if a client comes along now and says: 'Here's the dough; go to work on your system for doubling people and it's none of your business why I want it'-we wouldn't agree, right?" "Well, it's a little early to be worrying about that. The method hasn't been researched. What kind of production could there be? Who knows, maybe you'll disintegrate in a few months." "I won't. Don't count on it." "What's it to me? Live for all I care." "Thanks! You are such a boor! Just unbelievable! Would I like to give you a good punch!" "All right, all right, don't get off the subject. You misunderstood me. I meant that we still don't know all the aspects and possibilities of the discovery. We're at the very beginning. If we compare it to radio, say, then we're at the level of Hertz's waves and Popov's spark transmitter. What now? We must research the possibilities." "Right. But that doesn't change things. Any research that is applied to man and human society must have a definite goal. And there's nobody around to give us a two-page, typewritten list setting a technological task. But we don't need it. We must determine for ourselves what goals man now faces." "Well... before, the goals were simple: survival and propagation of the species. In order to achieve them you had to worry about wildlife, skins for cover, and fire . . . beating off animals and acquaintances with a cudgel, digging in the clay to make a cave without any conveniences, and so on. But modern society has solved these problems. Get a job somewhere and you'll have the minimum you need for living. You won't perish. And you can have children; if worst comes to worst, the government will even take on the responsibility of bringing them up for you. So now, it follows that people should have new desires and needs." "More than you can count! Comfort, recreation, interesting and not boring work. Refined society, various symbols of vanity-titles, awards, medals. The need for excellent clothing, delicious food, embroidery, a suntan, news, books, humor, ornamentation, fads...." "But none of that is important, damn it! That can't be important. People can't, and don't want to return to their previous primitive existence; they squeeze everything from modern life that they can-it's only natural. But there has to be some goal behind their desires and needs, no? A new goal of existence." "In brief, what is the meaning of life? Rather a complicated problem, wouldn't you say? So, I knew we would end up here!" My double got up, moved to get the kinks out of his body, and sat down again. So-starting out with jokes and getting more and more serious-we discussed the most important aspects of our work. I've often gotten around to discussing the meaning of life-over cognac or on a coffee break-as well as social structure, and the destiny of mankind. Engineers and scientists like to gab about worlds the way housewives do about high prices and lack of morality. Housewives do it to prove their diligence and goodness, and the researchers do it to demonstrate the breadth and scope of their vision to their friends. But this conversation was much more difficult than the usual engineering bull: we overturned ideas as if they were snowdrifts. It was distinguished by responsibility: after this conversation deeds and actions would follow the words-deeds and actions that allowed no room for mistakes. We weren't sleepy any more. "All right. Let's assume that the meaning of life is to satisfy needs. No matter what kind. But what desires and needs of mankind can we satisfy by creating new people? The artificially created people will have their own needs and desires! It's a vicious circle." "No, no. The meaning of life is to live. Live a full life, freely, interestingly, creatively. Or at least to aim for that... and then?" "Fully! Meaning of life! Aiming!" My double jumped up and started pacing the room. "Interests, desires, . . . mammy, what abstractions! Two centuries ago these approximate concepts would have sufficed, but today.... What the hell can we do if there are no exact data on man? What vectors are used to describe striving? What units measure interests?" (We were discouraged by that then-and we're discouraged by that now. We were used to exact, precise concepts: parameters, clearances, volume of information in bits, action in microseconds-and we came face to face with the terrifying vagueness of knowledge about man. It's good enough for a conversation. But please, do tell me how can you use them in applied research, where a simple and harsh law reigns: if you know something imprecisely, that means you don't know it.) "Hmmmmmm ... I envy the men who invented the atom bomb." My double got up and leaned in the balcony doorway." 'This device, gentlemen, can destroy a hundred thousand people'-and it was perfectly clear to them that Oak Ridge had to be built... And our device can create people, gentlemen!" "Some people do research on uranium; others build factories to enrich uranium with the necessary isotopes ... others construct the bombs... others in high political circles give the order... others drop the bombs on still others, the inhabitants of Hiroshima and Nagasaki ... and others.... Hey, wait a minute, I'm on to something!" My double regarded me with curiosity. "You see, we're talking very logically, and we can't find our way out of the paradoxes, the dead questions like 'What's the meaning of life?' and you know why? There is no such thing in nature as Man in General. On earth there are all kinds of different people, and their desires are varied, and often contradictory. Let's say a man wants to live well and for that he needs weapons. Or take this: a young man dreams of becoming a scientist but he doesn't feel like chewing on the granite of science-he doesn't like the taste. And these different people live in different circumstances, find themselves in varying situations, dream about one thing and strive for another, and achieve yet a third ... and we're trying to fit them all in one mold!" "But if we move on to individuals and take into account all the circumstances ..." my double frowned, "it'll be a mess!" "And you want everything to be as simple as the creation of storage blocks, eh? Wrong case." "I know it's a different case. Our discovery is as complex as man himself... and we can't throw anything out or simplify anything to make our work easier. But what constructive ideas are flowing out of your great insight that all men are different? I mean constructive, that will help our work." "Our work ... hm. It's tough...." Our conversation hit another dead end. The poplars rustled downstairs by the house. Someone walked into the courtyard, whistling a tune. A cool breeze came in from the balcony. My double was staring dully at the lamp and then shoved his finger second-knuckle deep into his nostril. His face expressed the fierce pleasure of natural exercise. Something itched in my right nostril, too, but he had beat me to it. I watched myself picking my nose and I suddenly realized why I hadn't recognized my double when we met on the institute grounds. Basically, no one knows himself. We never see ourselves-even before the mirror we unconsciously correct ourselves, trying to look better and more intelligent. We don't hear ourselves, because the vibrations of our thorax reach our eardrums through the bones and muscles of our head as well as through the air. We do not observe ourselves from the side. My double cleaned his nose, and then his finger, and then looked up and laughed, when he understood what I was thinking. "So, are people different or the same?" "Both. A certain objective lesson can be drawn here-not from your lousy manners, of course. We're talking about the technical production of a new information system-Man. Technology produces other systems: machines, books, equipment.... The common factor in every produced system is similarity, standardization. Every book in a given press run is like all the others, down to the typos. And in equipment of a given series, the needles, the scales, the class of precision, and the length of the guarantee are the same. The differences are minor: in one book the text is a little clearer; in one piece of equipment there's a scratch or it has a slightly higher margin of error at high temperatures..." "... but within the class of precision." "Natch. In the language of our science, we could say that the volume of individual information in each such artificial system is negligibly small in comparison with the volume of information that is common in all the systems of a given class. And for man that is not the case. People contain common information, biological knowledge of the world, but each person has an enormous amount of personal, individualized information. You can't overlook it-without it man is not man. That means that every person is not standard. That means..." "... that all attempts to find the optimum parameters for man with an allowable margin of error of no more than five percent is a waste of time. Fine! Do you feel better?" "No. But that's the harsh truth." 'Therefore, we can't hide in our work from these terrible and mysterious concepts: man's interests, personality, desires, good and evil... and maybe even the soul? I'm going to quit." "You won't. By the way, are they really so mysterious, these concepts? In life people all understand what's what. You know, they judge a base act and say, 'You know, that was lousy! and everyone agrees." "Everyone except the louse. Which is very much to the point." He slapped his thighs. "I don't understand you! It's not enough that you got burned on the simple word understanding? Now you want to give the computer problems with good and evil? A machine doesn't catch things between the lines, doesn't get jokes, is indifferent to good and evil... Why are you laughing?" I really was laughing. "I don't understand how you cannot understand me. After all you are me!" "That's tangential. I'm a researcher first, and then I'm Krivoshein, Sidorov, or Petrov!" He was obviously all worked up. "How will we work if we don't have precise concepts of the crux of the matter?" "Well . . . the way people worked at the dawn of the age of electrotechnology. In those days everyone knew what phlogiston was, but no one had any idea about tension, voltage, or induction. Ampere, Volt, Henry, and Ohm were merely last names. They tested tension with their tongues, the way kids check batteries nowadays. They discovered current by copper buildup on cathodes. But people worked. And we ... what's the matter with you?" Now my double was doubled up with laughter. "I can just imagine it: twenty years from now there'll be a unit measuring something and they'll call it a krivoshein! Oh, I can't stand it!" I fell down on my bed laughing, too. "And there'll be a krivosheinmeter... like an ohmmeter." "And a microkrivoshein or a megakrivoshein ... a megakri for short. Ho-ho!" I like remembering how we roared. We were obviously unworthy of our discovery. We laughed. We got serious. "Historical examples are inspirational, of course," my double said. "But that's not it. Galvani could blather as much as he wanted over 'animal electricity,' Zeebeck could stubbornly insist that thermo-stream gave rise not to thermoelectricity, but to thermomag-netism-the nature of things was not altered by that. Sooner or later they hit on the truth, because the important thing was the analysis of information. Analysis! And we're dealing with synthesis. And here nature is no guideline for man: it builds its own system; he builds his. The only truths for him in this business are possibility and goal. We have the possibility. And the goal? We can't formulate it." "The goal is simple: for everything to be good." "Again with good?" My double looked at me. "And then we have childish prattle about what is good and what is bad?" "Skip the childish prattle! Let's operate with these arbitrary concepts however clumsy they may be: good, evil, desires, needs, health, talent, stupidity, freedom, love, longing, principle-not because we like them, but because there aren't any others. They don't exist!" "I have nothing to counter that. There aren't any others, that's true." My double sighed. "I can tell this is going to be a lot of work!" "And let's talk it all out. Yes, things should be good. All the applications of the discovery that we permit to enter the world must be ones that we are sure of, that will not bring any harm to people, only good. And let's put aside our discussion of how to measure benefit. I don't know what units it takes." "Krivosheins, of course," my double countered. "Cut it out! But I know something else: the role of an intellectual monster on a world scale does not appeal to me." "Me neither. But just a small question: do you have a plan?" "For what?" "A method for using the computer-womb so that it only gives benefit to mankind. You see this would be an unprecedented method in the history of science. Nothing that has been invented and is being invented has that magical quality. You can poison yourself with medicine. You can use electricity for lighting homes or for torturing people. Or for launching a rocket with a warhead. And that holds for everything." "No, I don't have a concrete plan as yet. We don't know enough. Let's study the computer-womb and look for that method. It must exist. It's not important that there is no precedent for it in science-there is no precedent for our discovery either. We will be synthesizing precisely that system that does good and evil, and miracles, and nonsense-man!" "That's all true," my double agreed after some thought. "Whether we find that great method or not, there's no point in undertaking work like that without a goal like it. They manage to make people without us, somehow or other...." "So, let's end the session properly, all right?" I suggested. "Let's make up a work project like in a contract: we the undersigned: humanity, called the client, and the party of the first part; and the heads of the New Systems Laboratory of the Institute of Systemology, V. V. Krivoshein and V. V. Krivoshein, called the Executors, and the party of the second part, agree to the following...." "Why so much about a contract and a technical task-after all in this work we represent the interests of the client ourselves. Do it straight and simple!" He got up, took down the Astra-2 cassette recorder from the closet, put it on the table, and turned on the microphone. And we-that is, I, Valentin Vasilyevich Krivoshein, thirty-four years old, and my artificial double, who appeared on this earth a week ago-two unsentimental, rather ironic people-swore a vow. I guess it might have seemed high-flown and ridiculous. There was no fanfare, no flags, no rows of students at ease. The morning sky was pale, and we stood before the mike in our underwear, and the draft from the balcony chilled our feet... but we made the vow in dead earnest. And so it will be. No other way. Chapter 11 If, when you come home at night, you mistakenly drink developing fluid instead of water, you might as well have some fixative, or you'll leave things half-done. -K. Prutkov-enzhener, Thought 21 The next day we started building an information chamber in the laboratory. We marked off an area of two meters square, covered it with laminated insulation panels and dumped into it all the microphones, analyzers, feelers, and objectives-all the sensors that had been strewn colorfully all over the place by the computer-womb. This was our idea: a living object would get into the chamber, and would gambol, feed, fight with one of its own kind, or just ramble, surrounded by sensors, and the computer would receive information for synthesis. The "living objects" are calmly chewing their cabbage to this day in their cages in the hall. My double and I were always getting into fights about who would tend them. They were rabbits. I traded the bionics lab a loop oscillograph and a GI-250 generator lamp for them. One rabbit (Albino Vaska) had something like a bronze crown on his head made out of electrodes implanted for encephalograms. On May 7 we had a minor but unpleasant occurrence. Usually my double and I coordinated all our work fairly well, so that we would not appear in public simultaneously or repeat ourselves. But that damned lab of experimental apparatus could drive anyone to distraction. Back in the winter I had ordered a universal system of biosensors from the lab. I prepared the blueprints, a mounting diagram, ordered all the necessary materials and parts-they only had to put it together. And it still wasn't finished! I needed to install the system in the chamber, and I didn't have it. The trouble was that the lab was chronically changing directors. One guy turns over the work; the other accepts it-naturally there's no one to do the work. Then the new director has to acquaint himself with the situation, introduce reforms and changes (a new broom sweeps clean), and no work gets done. Meanwhile the people who have placed orders scream and fume, go to Azarov with their complaints, and a new director is put on the job. See above. I even tried influencing the workers directly, slipping them some booze, getting P657 transistors for their radios-and to no avail. Eventually the reserve of people willing to head that lab dried out, and H. H. Hilobok took over, while continuing his other duties, at half pay-Harry is like this: he'll take on any job. He'll organize anything, reorganize, so long as he is not left one on one with nature, with those horrible pieces of equipment that can't be bossed and bullied but which show things as they really are and what needs to be done. That day I had called Gavryushenko at the lab. And I heard the same vague muttering about a lack of mounting wire. I freaked out and rushed over to have it out with Harry. I was so mad that I didn't notice that Harry seemed a little confused, and I told him off. I promised to turn the work over to schoolchildren and shame the lab completely. And when I got back to the lodge, I encountered my sweet double, pacing and cooling off. It seems he had just seen Hilobok five minutes earlier and had the exact same conversation with him. Damn... at least we hadn't bumped into each other. In our first experiments we decided to make do without the universal system. The sensors we had were enough for the rabbits. And when we moved on to homo sapiens ... by then maybe the lab of experimental apparatus might even have an efficient director. The scientific council took place on May 16. The might before, we went over what should be said and what should be omitted. We decided to introduce the original idea, that a computer with elements of random transmission might and must construct itself under the influence of random information. The work would be an experimental test of that idea. In order to determine the limits that the computer can reach in constructing itself, the following equipment, material and apparatus would be necessary-see appended list. "To prepare their minds, just like the supply department, this will be just right," I said. "So, that's what I'll report." "But, why, does it have to be you?" my double asked, militantly raising his eyebrows. "When the rabbits need cleaning it's me; when it's the scientific council, it's you, huh? What kind of discrimination against artificial people is this? I demand we do it by lot!" And that's how I innocently earned a talking to for "tactless behavior at the scientific council of the institute and for rudeness toward Doctor of Technical Sciences Professor 1.1. Voltampernov." No, it really hurt. If it had been to me that the former hotshot of lamp electronics, honored worker of the republic in science and technology, doctor of technical sciences, and professor, Ippolit Illarionovich Voltampernov (oh, why wasn't I a master of ceremonies?) had let loose his: "And does engineer Krivoshein know, since he bids us to give a computer its head, so to speak, without rudder or wheel, what it will want to do in building itself, and how much thought-out, I dare add, work our qualified specialists here at the institute put into the planning and projecting of computer systems? Into the development of blocks of these systems? And the elements of these systems? Does he have any idea, this engineer who's vulgarizing principles here before us, of at least the methodology, so to speak, of the optimal projection of flip-flops on the 6N5 bulb? And doesn't it seem to engineer Krivoshein that his ideas-regarding the fact the computer, so to speak, will manage the optimal construction better than the specialists-are an insult to the majority of the workers of this institute who are fulfilling, I dare say, work that is important for our country's economy? I would ask the engineer what this would give the...." And each time the word "engineer" sounded like a cross between "student" and "son of a bitch." I wish I could have reminded the respected professor in my reply that apparently the same sort of insult was the motive force of his pen in the past, when he wrote the exposes about "the reactionary pseudoscience of cybernetics," but a shift in wind made him take up the work, too. If the professor was worried about being left out after the success of the present work, he shouldn't have been: he could always return to semiscientific journalism. And in general, it's about time to learn that science functions with the use of statements on the heart of the matter and not with the aid of demagogic attacks and sputterings. It was after these words, taken down by the stenographer, that Voltampernov began yawning convulsively and clutching his breast pocket. But citizens, that was not me! The report was given by my artificial double, made exactly like me by the proposed method. Voltampernov was angry and embarrassed for three days after that. I could understand him! (But, by the way, at the moment when Azarov signed the official order for a reprimand and it reached the office, I was the one who was around. And it was at me that Aglaya Mitrofanovna Garazha, the tough woman head of the office, yelled in front of a large group: "Comrade Krivoshein, here's a reprimand for you! Come in and sign for it!" And like a lamb, I went in and signed. Isn't fate cruel?) Actually, the hell with the reprimand. The important thing is that the topic was supported! By Azarov himself. "An interesting idea," he said, "and a rather simple one; it can be checked." "But this isn't an algorithmic problem, Arkady Arkadievich," assistant professor Prishchepa, the most orthodox mathematician of our institute, interjected. "And if it isn't algorithmic, it shouldn't exist?" the academician parried. (Listen to the man.) "In our times the algorithm of scientific retrieval is not reduced to a collection of rules of formal logic." Now that's talking! Azarov never liked "random retrieval," I knew that. What was this? Could my double have conquered him with his logic? Or had our chief suddenly developed some scientific tolerance? Then we would get along fine. In a word, the vote was eighteen yea's and one (Voltampernov) nay. The careful Prishchepa abstained. My double, who did not have a learned degree and title, did not vote. Even Hilobok voted for it, and he believes in the success of our work. We won't let you down, not to worry. By the way, my double brought some amazing news: Hilobok was writing his dissertation. "On what?" "An undisclosed topic. The scientific council was hearing the agenda for the next meeting, and on point it was: "Discussion of the work on his dissertation for a learned degree as doctor of technical sciences by H. H. Hilobok. The topic is marked top secret." See, we sit here in the lab, cut off from the mainstream of science." "An undisclosed topic-that's fantastic!" I even disconnected my welding iron. We were in the lab, mounting sensors in the chamber. 'Terrific. No open publication, no audience at the defense ... shhh, comrades, top secret! Everyone walks around respecting it from the start." The news hurt me to the quick. I couldn't do my masters and here Harry was going to be a doctor. And he was. The technique involved was well known: you take a secret circuit or construction that is being developed (or even has been developed) somewhere, and add on some compilative verbiage using secret primary sources. "Ah, he's not the first, and he's not the last!" I said, picking up my soldering iron. "Good old Harry! Of course, we could give him a bit of... but is the game worth the candle?" We were a little uneasy about it. 1 was always angry when I had to watch a bootlicker making progress at full speed; I experience angry thoughts and begin to despise myself for the reasonable recalcitrance of my extremities. But really, the game wasn't worth the candle. We had so much serious work for just the two of us, and my position was not yet secure-I shouldn't get involved. Especially not with Harry Hilobok. Ivanov and I once tried to catch Harry in plagiarism. Valery appeared at a seminar, proved everything. But all that happened was that the scientific council recommended that Hilobok rework his article. And then he tried ruining our lives for ever after.... And these public face slappings in front of an audience-with the usual discussions afterward, when people no longer greet each other-are not my piece of cake. When they occur I experience an uncontrollable urge to beat it to my lab, turn on all the equipment, take down data in my journal, and try to do something worthwhile. Now if there were some way to fix guys like Harry with lab methods-you know, the power of engineering thought.... It was worth thinking about. The act that the Voltampernovs and Hiloboks roll out onto the broad highway of science is proof that there are not enough smart people around. And this is in science, where the intellect is the fundamental measuring stick of a man's qualities. How about in other fields? They put up want ads: "Lathe workers wanted" or "Wanted: engineers, technicians, accountants, and supply personnel." But no one writes "Wanted: smart people. Apartment comes with job." Are they too embarrassed? Or are there no apartments? You could start off without the apartments.... Why hide it? Smart people are wanted, and how! They're wanted for life, for the development of society. "We must... make doubles of smart people!" I shouted. "Smart, active, decent people! Val, that's the best application!" He looked at me with undisguised sadness. "You beat me to it, you bum." "And this will be a reward for those people for living," I went on. "Society needs you. You know how to work fruitfully, live honestly. And that means there should be more like you! Maybe even several; there'll be enough work for all. Then we'll crowd out the Hiloboks...." This idea revived our self-respect. We felt ourselves on top of things once more and spent the day dreaming about how we would multiply talented scholars, writers, musicians, inventors, heroes.... It really wasn't a bad idea! Chapter 12 A scientific fact: the sound "a" is pronounced without any pressure of the tongue, by exhaling; if at the same time you open and close your mouth, you get "ma... ma ...." That is the origin of a child's first word. That means that the child is taking the path of least resistance. What are the parents so happy about? -K. Prutkov-enzhener, Thought 53 The first few weeks I was still wary of my double: what if he suddenly disintegrated or dissolved? Or went berserk? He was an artificial creation. Who knew? But no way! He fiercely put away sausage and yogurt drinks in the evening after a tough day at the lab, enjoyed his long baths, liked to have a smoke before going to sleep-in a word, just like me. After the Hilobok incident, we carefully plotted out the day every morning: where would we be, doing what? When would we eat at the cafeteria? At what time would each of us go through the entryway, so that Vakhterych would forget in the rush that one Krivoshein had already gone through. In the evening we would tell each other whom we had seen and what we had talked about. The only thing we didn't discuss was Lena. It was as though she did not exist. I even took her photo off my desk. And she didn't come over or call-she was mad at me. And I didn't call her. And neither did he... but she was still there. It was May, a poetic, glorious southern May-with blue twilights, nightingales in the park, and huge stars above the trees. The chestnut blooms were falling and the acacias were flowering. The sweet, troubling scent penetrated the lab, disturbing our work. We both felt gypped. Ah, Lena, my dear, passionate Lena, reveling in love, why is there only one of you on earth? That's the childishness the appearance of my double and "rival" bought out in me! Until then Lena and I had the usual relationship between two worldly-wise people (Lena had divorced her husband the year before; I'd had my share of broken affairs, which turned me into a confirmed bachelor) that comes not so much as the result of mutual attraction but of loneliness. In a relationship like that neither gives himself completely. We enjoyed our dates and tried to pass time in an interesting way; she would spend the night at my place or I would stay at hers; in the mornings we would both be a little uncomfortable and separate with relief. Then I would be drawn to her again and she to me... and so on. I was in love with her beauty (it was great to watch men looking at her in the street or in a restaurant), but I was often bored by her conversation. And as for her... well, who understands a woman's heart? I often had the feeling that Lena expected something more from me, but I never tried to find out what. And now, where there was danger of losing Lena, I suddenly felt that I needed her desperately, and that without her my life would be empty. And we're all like that! But the construction of the chamber was going along swimmingly. In complex work like that it's important to understand each other-and in that sense it was an ideal arrangement: my double and I never explained anything to each other; one simply replaced the other and went on working. We never argued once about placement of sensors, or where to set up the plugs and sockets or screens. "Listen, are you getting a little worried by our idyl?" my double asked one day, as we changed guard. "No questions, no doubts. We're going to make mistakes in complete harmony." "What else? You and I have four arms, four legs, two stomachs, and one head for the two of us-the same knowledge, the same life experience ...." "But we argued, contradicted each other!" "We were simply thinking aloud together. You can argue with yourself. Man's thoughts are mere variants of actions and they are always contradictory. But we strive to act together." "Yes... but that's no good! We're not working now, we're plugging away. An extra pair of hands doubles the work capacity. But our main function is to think. And here... listen, original, we have to become different." I couldn't imagine what serious repercussions this innocent conversation would have. And, as they write in novels, the repercussions didn't make us wait. It began with my double buying a volume of Human Physiology intended for secondary phys ed courses. I won't try to guess whether he had really planned to distinguish himself from me or whether he was simply attracted by the bright green cover and gold lettering, but as soon as he opened it, he began muttering "Aha! Now that's something,..." as if he were reading a catchy mystery, and then he bombarded me with questions: "Do you know that nerve cells can be up to a meter long?" "Do you know what controls the sympathetic nervous system?" "Do you know what protective inhibition is?" Naturally, I didn't know. And he went on telling me with a neophyte's enthusiasm about the sympathetic nervous system regulating the functions of the internal organs, that protective inhibition or pessimum, occurs in nerve tissue when the strength of excitation exceeds the permissible level. "You understand, the nerve cell can refuse to react to a powerful stimulus in order not to destroy itself! Transistors can't do that!" After that textbook he bought up a whole batch of biology books and journals, read them cover to cover, quoting his favorite passages, and got mad when I didn't share his enthusiasm. And why should I have? Graduate student Krivoshein set aside the diary. Yes, that's precisely how it all began. In the dry academic lines of the books and articles on biology he suddenly sensed the proximity of truth that he had earlier felt only when reading the works of great writers, when, delving into the actions and emotions of invented characters, you begin to learn something about yourself. Then he did not realize it, because the physiology facts had enthralled him, so to speak. But he was upset that original Krivoshein was left cold by it all. How could that be? They were the same; that meant that they had to react to things the same way. Did that mean that he, the artificial Krivoshein, wasn't the same? That was the first hint. The second time he overslept-sitting up reading until dawn-I blew up: "Why can't you get interested in mineralogy-or production economics-if you want so badly to be different! At least you'd get some sleep." We were talking in the lab, after my double arrived past noon, sleepy and unshaven; I had shaved in the morning. That kind of discrepancy was enough to worry our institute friends. He gave me a haughty and surprised look. "Tell me, what's that liquid?" and he pointed at the tank. "What is its composition?" "Organic, of course, why?" "It's not tricky. Why did the computer-womb use ammonia and phosphoric acid? Remember? It kept spewing out formulas and amounts and you ran around all the stores like a crazy man, trying to find it all. Why did you get it?! You don't know? I'll explain: the computer was synthesizing atpase and phosphocreatine-the sources of muscle energy. Understand?" "I understand. But what about Galosha brand gas? And calcium rhodanate? And the methylviolet? And the other three hundred reagents?" "I don't know yet. I have to read up on biochemistry...." "Uh-huh... and now I'll explain to you why I got those disgusting things: I was fulfilling the logical conditions of the experiment-the rules of the game, and nothing else. I did not know about your superphosphate. And the computer probably didn't know that the formulas it was turning out in binary code had such fancy names-because nature is made up of structural elements and not names. And yet it asked for ammonia, phosphoric acid, and sugar, and not for vodka or strichnine. It figured out for istelf, and without textbooks, that vodka is a poison. And it created you without textbooks and medical encyclopedias-it modeled you from life." "I don't see why you're so uptight about biology. It has everything we need: knowledge about life and man. For example . . ."-he was trying to convince me, it was obvious-"did you know that conditioned reflexes are created only when the conditioning stimulus precedes an unconditioned one? The cause precedes the effect, understand? The nervous system has a greater sense of causality than any philosophy book! And biology uses more precise terms than everyday life. You know, how they write in novels: 'The unconscious terror widened his pupils and made his heart beat faster.' The sympathetic system went to work. There you go...." He leafed through his green bible. " 'Under the influence of impulses passing through the sympathetic nerves, the following occurs: a) dilation of pupils through the contraction of the radial muscles of
