Asimov’s Future History Volume 11, Page 2

  Amadiro received his reports for nine days.

  Mandamus talked to his robots, occasionally to colleagues at the university, and even more occasionally to individuals at the establishments neighboring his. His conversations were utterly trivial and, long before the nine days had passed, Amadiro had decided he could not outwait the young man. Mandamus was only at the beginning of a long life and might have thirty decades ahead of him; Amadiro had only eight to ten at the very most.

  And Amadiro, thinking of what the young man had said, felt, with increasing restlessness, that he could not take the chance that a way of destroying Earth might exist and that he might be ignoring it. Could he allow the destruction to take place after his death, so that he would not witness it? Or, almost as bad, have it take place during his lifetime, but with someone else’s mind in command, someone else’s fingers on the contact?

  No, he had to see it, witness it, and do it; else why had he endured his long frustration? Mandamus might be a fool or a madman, but, in that case, Amadiro had to know for certain that he was a fool or a madman.

  Having reached that point in his thinking, Amadiro called Mandamus to his office.

  Amadiro realized that in so doing, he was humiliating himself, but the humiliation was the price he had to pay to make certain that there wasn’t the slightest chance of Earth being destroyed without him. It was a price he was willing to pay.

  He steeled himself even for the possibility that Mandamus would enter his presence, smirking and contemptuously triumphant. He would have to endure that, too. After the endurance, of course, if the young man’s suggestion proved foolish, he would see him punished to the full extent that a civilized society would permit, but otherwise

  He was pleased, then, when Mandamus entered his office with an attitude of reasonable humility and thanked him, in all apparent sincerity, for a second interview. It seemed to Amadiro he would have to be gracious in his turn.

  “Dr. Mandamus,” he said, “in sending you away without listening to your plan, I was guilty of discourtesy. Tell me, then, what you have in mind and I will listen until it is quite clear to me – as I suspect it will be – that your plan is, perhaps, more the result of enthusiasm than of cold reason. At that time, I will dismiss you again, but without contempt on my part, and I hope that you will respond without anger on your part.”

  Mandamus said, “I could not be angry at having been accorded a fair and patient hearing, Dr. Amadiro, but what if what I say makes sense to you and offers hope?”

  “In that case,” said Amadiro slowly, “it would be conceivable that we two could work together.”

  “That would be wonderful, sir. Together we could accomplish more than we could separately. But would there be something more tangible than the privilege of working together? Would there be a reward?”

  Amadiro looked displeased. “I would be grateful, of course, but all I am is a Councilman and the head of the Robotics Institute. There would be a limit to what I could do for you.”

  “I understand that, Dr. Amadiro. But within those limits could I not have something on account? Now?” He looked at Amadiro steadily.

  Amadiro frowned at finding himself gazing into a pair of keen and unblinkingly determined eyes. No humility there!

  Amadiro said coldly, “What do you have in mind?”

  “Nothing you can’t give me, Dr. Amadiro. Make me a member of the Institute.”

  “If you qualify –”

  “No fear. I qualify.”

  “We can’t leave that decision to the candidate. We have to –”

  “Come, Dr. Amadiro, this is no way to begin a relationship. Since you’ve had me under observation every moment since I left you last, I can’t believe you haven’t studied my record thoroughly. As a result, you must know I qualify. If, for any reason, you felt I did not qualify, you would have no hope whatever that I would be ingenious enough to work out a plan for the destruction of our particular Carthage and I wouldn’t be back here at your call.”

  For an instant, Amadiro felt a fire blaze within him. For that instant, he felt that even Earth’s destruction was not worth enduring this hectoring attitude from a child. But only for that instant. Then his sense of due proportion was back and he could even tell himself that a person so young, yet so bold and so icily sure of himself, was the kind of man he needed. Besides, he had studied Mandamus’s record and there was no question that he qualified for the Institute.

  Amadiro said evenly (at some cost to his blood pressure), “You are right. You qualify.”

  “Then enroll me. I’m sure you have the necessary forms in your computer. You have but to enter my name, my school, my year of graduation, and whatever other statistical trivia you require and then sign your own name.”

  Without a word in reply, Amadiro turned to his computer. He entered the necessary information, retrieved the form, signed it, and handed it to Mandamus. “It is dated today. You are a fellow of the Institute.”

  Mandamus studied the paper, then handed it to one of his robots, who placed it in a small portfolio which he then placed under his arm.

  “Thank you,” said Mandamus, “it is most kind of you and I hope I will never fail you or cause you to regret this kind estimate you have given me of my abilities. That, however, leaves one more thing.”

  “Indeed? What?”

  “Might we discuss the nature of the final reward – in case of success only, of course. Total success.”

  “Might we not leave that, more logically, to the point where total success is achieved or is reasonably close to being achieved?”

  “As a matter of rationality, yes. But I am a creature of dreams as well as of reason. I would like to dream a little.”

  “Well,” said Amadiro, “what is it you would like to dream?”

  “It seems to me, Dr. Amadiro, that Dr. Fastolfe is now by no means well. He has lived long and cannot stave off death for many more years.”

  “And if so?”

  “Once he dies, your party will become more aggressive and the more lukewarm members of Fastolfe’s party will find it expedient to change allegiance, perhaps. The next election, without Fastolfe, will surely be yours.”

  “It is possible. And if so?”

  “You will become the de facto leader of the Council and the guide of Aurora’s foreign policy which would, in fact, mean the foreign policy of the Spacer worlds in general. And if my plans flourish, your direction will be so successful that the Council will scarcely fail to elect you Chairman at their earliest opportunity.”

  “Your dreams soar, young man. And if all you foresee were to come true, what then?”

  “You would scarcely have time to run Aurora and the Robotics Institute, too. So I ask that when you finally decide to resign from your present position as the head of the Institute, you be prepared to support me as your successor to the post. You could scarcely expect to have your personal choice rejected.”

  Amadiro said, “There is such a thing as qualification for the post.”

  “I will qualify.”

  “Let us wait and see.”

  “I am willing to wait and see, but you will find that well before complete success is ours, you will wish to grant this request of mine. Please grow accustomed to the idea, therefore.”

  “All this before I hear a word,” murmured Amadiro. “Well, you are a member of the Institute and I will strive to grow accustomed to your personal dream, but now let us have an end to preliminaries and tell me how you intend to destroy Earth.”

  Almost automatically, Amadiro made the sign that indicated to his robots that they were not to remember any part of the conversation. And Mandamus, with a small smile, did the same for his.

  “Let us start, then,” said Mandamus. But before he could speak further, Amadiro moved to the attack.

  “Are you sure you’re not pro-Earth?”

  Mandamus looked startled. “I am coming to you with a proposal to destroy Earth.”

  “And yet you are a descend
ant of the Solarian woman – in the fifth generation, I understand.”

  “Yes, sir, it is on public record. What of that?”

  “The Solarian woman is – and has been for a long time – a close associate – friend – protégée – of Fastolfe. I wonder you do not sympathize with his pro-Earth views, therefore.”

  “Because of my ancestry?” Mandamus seemed honestly astonished. For a moment, what might have been a flash of annoyance or even anger seemed to tighten his nostrils, but that vanished and he said quietly, “An equally longtime close associate – friend – protégée – of your own is Dr. Vasilia Fastolfe, who is Dr. Fastolfe’s daughter. She is a descendant in the first generation. I wonder she does not sympathize with his views.”

  “I have in the past also wondered,” said Amadiro, “but she doesn’t sympathize with them and, in her case, I have ceased wondering.”

  “You may cease wondering in my case, too, sir. I am a Spacer and I want to see the Spacers in control of the Galaxy.”

  “Very well, then. Go on with the description of your plan.”

  Mandamus said, “I will, but – if you don’t mind – from the beginning.

  “Dr. Amadiro, astronomers agree that there are millions of Earthlike planets in our Galaxy, planets on which human beings can live after necessary adjustments to the environment but without any need for geological terraforming. Their atmospheres are breathable, an ocean of water is present, the land and climate is suitable, life exists. Indeed, the atmospheres would not contain free oxygen without the presence of ocean plankton at the very least.

  “The land is often barren, but once it and the ocean undergo biological terraforming – that is, once they are seeded with Earth life – such life flourishes and the planet can then be settled. Hundreds of such planets have been recorded and studied and about half of them are already occupied by Settlers.

  “And yet not one habitable planet of all those which have been discovered to date has the enormous variety and excess of life that Earth has. Not one has anything larger or more complex than a small array of wormlike or insect-like invertebrates or, in the plant world, anything more advanced than some fernlike shrubbery. No question of intelligence, of anything even approaching intelligence.”

  Amadiro listened to the stiff sentences and thought: He’s speaking by rote. He’s memorized all this. – He stirred and said, “I am not a planetologist, Dr. Mandamus, but I ask you to believe that you are telling me nothing I don’t already know.”

  “As I said, Dr. Amadiro, I am starting from the beginning. – Astronomers are increasingly of the belief that we have a fair sample of the habitable planets of the Galaxy and that all – or almost all – are markedly different from Earth. For some reason, Earth is a surprisingly unusual planet and evolution has proceeded on it at a radically rapid pace and in a radically abnormal manner.”

  Amadiro said, “The usual argument is that if there were another intelligent species in the Galaxy that was as advanced as we are, it would have become aware of our expansion by now and have made themselves known to us – one way or another.”

  Mandamus said, “Yes, sir. In fact, if there were another intelligent species in the Galaxy that was more advanced than we are, we would not have had a chance to expand in the first place. That we are the only species in the Galaxy capable of traveling in hyperspace would seem certain, then. That we are the only species in the Galaxy that is intelligent is perhaps not quite certain, but there is a very good chance that we are.”

  Amadiro was now listening with a weary half-smile. The young man was being didactic, like a man stamping out the rhythm of his monomania in a dull beat. It was one of the marks of the crank and the mild hope Amadiro had had that Mandamus might actually have something that would turn the tide of history was beginning to fade.

  He said, “You continue to tell me the known, Dr. Mandamus. Everyone knows Earth seems unique and that we are probably the only intelligent species in the Galaxy.”

  “But no one seems to ask the simple question: ‘Why?’ The Earthpeople and the Settlers don’t ask it. They accept it. They have a mystic attitude toward Earth and consider it a holy world, so that its unusual nature is taken as a matter of course. As for the Spacers, we don’t ask it. We ignore it. We do our best not to think of Earth at all, since if we do, we are liable to go further and think of ourselves as having descended from Earthpeople.”

  Amadiro said, “I see no virtue in the question. We need not seek for complex answers to the ‘Why?’. Random processes plan an important role in evolution and, to some extent, in all things. If there are millions of habitable worlds, evolution may proceed on each of them at a different rate. On most, the rate will have some intermediate value; on some the rate will be distinctly slow, on others distinctly fast; on perhaps one it would proceed exceedingly slow and on another exceedingly fast. Earth happens to be the one on which it proceeded exceedingly fast and we are here because of that. Now if we ask ‘Why?’, the natural – and sufficient – answer is ‘Chance.” ‘

  Amadiro waited for the other to betray the crank by exploding in rage at a preeminently logical statement, presented in an amused way, that served to shatter his thesis completely. Mandamus, however, merely stared at him for a few moments out of his deep-set eyes and then said quietly, “No.”

  Mandamus let that stand for perhaps two beats and then said, “It takes more than a lucky chance or two to speed evolution a thousandfold. On every planet but Earth, the speed of evolution is closely related to the flux of cosmic radiation in which that planet is bathed. That speed is not the result of chance at all but the result of cosmic radiation producing mutations at a slow rate. On Earth, something produces many more mutations than are produced on other habitable planets and that has nothing to do with cosmic rays, for they do not strike Earth in any remarkable profusion. Perhaps you see a little more clearly, now, why the ‘Why?’ could be important.”

  “Well, then, Dr. Mandamus, since I am still listening, with rather more patience than I would have expected myself to possess, answer the question you so insistently raise. Or do you merely have the question and no answer?”

  “I have an answer,” said Mandamus, “and it depends upon the fact that Earth is unique in a second way.”

  Amadiro said, “Let me anticipate. You are referring to its large satellite. Surely, Dr. Mandamus, you are not advancing this as a discovery of yours.”

  “Not at all,” said Mandamus stiffly, “but consider that large satellites seem to be common. Our planetary system has five, Earth’s has seven and so on. All the known large satellites but one, however, circle gas giants. Only Earth’s satellite, the moon, circles a planet not much larger than itself.”

  “Dare I use the word ‘chance’ again, Dr. Mandamus?”

  “In this case, it may be chance, but the moon remains unique.”

  “Even so. What possible connection can the satellite have with Earth’s profusion of life?”

  “That may not be obvious and a connection may be unlikely – but it is far more unlikely that two such unusual examples of uniqueness in a single planet can have no connection at all. I have found such a connection.”

  “Indeed?” said Amadiro alertly. Now ought to come unmistakable evidence of crackpotism. He looked casually at the time strip on the wall. There really wasn’t much more time he could possibly spend on this, for all that his curiosity continued to be aroused.

  “The moon,” said Mandamus, “is slowly receding from Earth, due to its tidal effect on the Earth. Earth’s large tides are a unique consequence of the existence of this large satellite. Earth’s sun produces tides, too, but to only a third of the extent of the moon’s tides – just as our sun produces small tides on Aurora.

  “Since the moon recedes because of its tidal action, it was far closer to Earth during the early history of its planetary system. The closer the moon to the Earth, the higher the tides on Earth. These tides had two important effects on Earth. It flexed the Earth’s cr
ust continually as the Earth rotated and it slowed the Earth’s rotation, both through that flexing and through the friction of the ocean’s water tides on shallow sea bottoms – so that rotational energy was converted to heat.

  “The Earth, therefore, has a thinner crust than any other habitable planet we know of and it is the only habitable planet that displays volcanic action and that has a lively system of plate tectonics.”

  Amadiro said, “But even all this can have nothing to do with Earth’s profusion of life. I think you must either get to the point, Dr. Mandamus, or leave.”

  “Please bear with me, Dr. Amadiro, for just a little while longer. It is important to understand the point once we get to it. I have made a careful computer simulation of the chemical development of Earth’s crust, allowing for the effect of tidal action and plate tectonics, something that no one has ever done before in as meticulous and elaborate a way as I have managed to do – if I may praise myself.”

  “Oh, by all means,” murmured Amadiro.

  “And it turns out, quite clearly – I will show you all the necessary data at any time you wish – that uranium and thorium collect in Earth’s crust and upper mantle in concentrations of up to a thousand times as high as in any other habitable world. Moreover, they collect unevenly, so that scattered over the Earth are occasional pockets where uranium and thorium are even more concentrated.”

  “And, I take it, dangerously high in radioactivity?”

  “No, Dr. Amadiro. Uranium and thorium are very weakly radioactive and even where they are relatively concentrated, they are not very concentrated in an absolute sense. – All this, I repeat, is because of the presence of a large moon.”

  “I assume, then, that the radioactivity, even if not intense enough to be dangerous to life, does suffice to increase the mutation rate. Is that it, Dr. Mandamus?”

  “That is it. There would be more rapid extinctions now and then, but also more rapid development of new species – resulting in an enormous variety and profusion of life-forms. And, eventually, on Earth alone, this would have reached the point of developing an intelligent species and a civilization.”
