Trevize frowned. “How do you decide what is injurious, or not injurious, to humanity as a whole?”
“Precisely, sir,” said Daneel. “In theory, the Zeroth Law was the answer to our problems. In practice, we could never decide. A human being is a concrete object. Injury to a person can be estimated and judged. Humanity is an abstraction. How do we deal with it?”
“I don’t know,” said Trevize.
“Wait,” said Pelorat. “You could convert humanity into a single organism. Gaia.”
“That is what I tried to do, sir. I engineered the founding of Gaia. If humanity could be made a single organism, it would become a concrete object, and it could be dealt with. It was, however, not as easy to create a superorganism as I had hoped. In the first place, it could not be done unless human beings valued the superorganism more than their individuality, and I had to find a mind-cast that would allow that. It was a long time before I thought of the Laws of Robotics.”
“Ah, then, the Gaians are robots. I had suspected that from the start.”
“In that case, you suspected incorrectly, sir. They are human beings, but they have brains firmly inculcated with the equivalent of the Laws of Robotics. They have to value life, really value it. —And even after that was done, there remained a serious flaw. A superorganism consisting of human beings only is unstable. It cannot be set up. Other animals must be added—then plants—then the inorganic world. The smallest superorganism that is truly stable is an entire world, and a world large enough and complex enough to have a stable ecology. It took a long time to understand this, and it is only in this last century that Gaia was fully established and that it became ready to move on toward Galaxia—and, even so, that will take a long time, too. Perhaps not as long as the road already traveled, however, since we now know the rules.”
“But you needed me to make the decision for you. Is that it, Daneel?”
“Yes, sir. The Laws of Robotics would not allow me, nor Gaia, to make the decision and chance harm to humanity. And meanwhile, five centuries ago, when it seemed that I would never work out methods for getting round all the difficulties that stood in the way of establishing Gaia, I turned to the second-best and helped bring about the development of the science of psychohistory.”
“I might have guessed that,” mumbled Trevize. “You know, Daneel, I’m beginning to believe you are twenty thousand years old.”
“Thank you, sir.”
Pelorat said, “Wait a while. I think I see something. Are you part of Gaia yourself, Daneel? Would that be how you knew about the dogs on Aurora? Through Bliss?”
Daneel said, “In a way, sir, you are correct. I am associated with Gaia, though I am not part of it.”
Trevize’s eyebrows went up. “That sounds like Comporellon, the world we visited immediately after leaving Gaia. It insists it is not part of the Foundation Confederation, but is only associated with it.”
Slowly, Daneel nodded. “I suppose that analogy is apt, sir. I can, as an associate of Gaia, make myself aware of what Gaia is aware of—in the person of the woman, Bliss, for instance. Gaia, however, cannot make itself aware of what I am aware of, so that I maintain my freedom of action. That freedom of action is necessary until Galaxia is well established.”
Trevize looked steadily at the robot for a moment, then said, “And did you use your awareness through Bliss in order to interfere with events on our journey to mold them to your better liking?”
Daneel sighed in a curiously human fashion. “I could not do much, sir. The Laws of Robotics always hold me back. —And yet, I lightened the load on Bliss’s mind, taking a small amount of added responsibility on myself, so that she might deal with the wolves of Aurora and the Spacer on Solaria with greater dispatch and with less harm to herself. In addition, I influenced the woman on Comporellon and the one on New Earth, through Bliss, in order to have them look with favor on you, so that you might continue on your journey.”
Trevize smiled, half-sadly. “I ought to have known it wasn’t I.”
Daneel accepted the statement without its rueful self-deprecation. “On the contrary, sir,” he said, “it was you in considerable part. Each of the two women looked with favor upon you from the start. I merely strengthened the impulse already present—about all one can safely do under the strictures of the Laws of Robotics. Because of those strictures—and for other reasons as well—it was only with great difficulty that I brought you here, and only indirectly. I was in great danger at several points of losing you.”
“And now I am here,” said Trevize. “What is it you want of me? To confirm my decision in favor of Galaxia?”
Daneel’s face, always expressionless, somehow managed to seem despairing. “No, sir. The mere decision is no longer enough. I brought you here, as best I could in my present condition, for something far more desperate. I am dying.”
102.
PERHAPS IT WAS BECAUSE OF THE MATTER-OF-FACT way in which Daneel said it; or perhaps because a lifetime of twenty thousand years made death seem no tragedy to one doomed to live less than half a percent of that period; but, in any case, Trevize felt no stir of sympathy.
“Die? Can a machine die?”
“I can cease to exist, sir. Call it by whatever word you wish. I am old. Not one sentient being in the Galaxy that was alive when I was first given consciousness is still alive today; nothing organic; nothing robotic. Even I myself lack continuity.”
“In what way?”
“There is no physical part of my body, sir, that has escaped replacement, not only once but many times. Even my positronic brain has been replaced on five different occasions. Each time the contents of my earlier brain were etched into the newer one to the last positron. Each time, the new brain had a greater capacity and complexity than the old, so that there was room for more memories, and for faster decision and action. But—”
“But?”
“The more advanced and complex the brain, the more unstable it is, and the more quickly it deteriorates. My present brain is a hundred thousand times as sensitive as my first, and has ten million times the capacity; but whereas my first brain endured for over ten thousand years, the present one is but six hundred years old and is unmistakably senescent. With every memory of twenty thousand years perfectly recorded and with a perfect recall mechanism in place, the brain is filled. There is a rapidly declining ability to reach decisions; an even more rapidly declining ability to test and influence minds at hyperspatial distances. Nor can I design a sixth brain. Further miniaturization will run against the blank wall of the uncertainty principle, and further complexity will but assure decay almost at once.”
Pelorat seemed desperately troubled. “But surely, Daneel, Gaia can carry on without you. Now that Trevize has judged and selected Galaxia—”
“The process simply took too long, sir,” said Daneel, as always betraying no emotion. “I had to wait for Gaia to be fully established, despite the unanticipated difficulties that arose. By the time a human being—Mr. Trevize—was located who was capable of making the key decision, it was too late. Do not think, however, that I took no measure to lengthen my life span. Little by little I have reduced my activities, in order to conserve what I could for emergencies. When I could no longer rely on active measures to preserve the isolation of the Earth/moon system, I adopted passive ones. Over a period of years, the humaniform robots that have been working with me have been, one by one, called home. Their last tasks have been to remove all references to Earth in the planetary archives. And without myself and my fellow-robots in full play, Gaia will lack the essential tools to carry through the development of Galaxia in less than an inordinate period of time.”
“And you knew all this,” said Trevize, “when I made my decision?”
“A substantial time before, sir,” said Daneel. “Gaia, of course, did not know.”
“But then,” said Trevize angrily, “what was the use of carrying through the charade? What good has it been? Ever since my decision, I have scoure
d the Galaxy, searching for Earth and what I thought of as its ‘secret’—not knowing the secret was you—in order that I might confirm the decision. Well, I have confirmed it. I know now that Galaxia is absolutely essential—and it appears to be all for nothing. Why could you not have left the Galaxy to itself—and me to myself?”
Daneel said, “Because, sir, I have been searching for a way out, and I have been carrying on in the hope that I might find one. I think I have. Instead of replacing my brain with yet another positronic one, which is impractical, I might merge it with a human brain instead; a human brain that is not affected by the Three Laws, and will not only add capacity to my brain, but add a whole new level of abilities as well. That is why I have brought you here.”
Trevize looked appalled. “You mean you plan to merge a human brain into yours? Have the human brain lose its individuality so that you can achieve a two-brain Gaia?”
“Yes, sir. It would not make me immortal, but it might enable me to live long enough to establish Galaxia.”
“And you brought me here for that? You want my independence of the Three Laws and my sense of judgment made part of you at the price of my individuality? —No!”
Daneel said, “Yet you said a moment ago that Galaxia is essential for the welfare of the human—”
“Even if it is, it would take a long time to establish, and I would remain an individual in my lifetime. On the other hand, if it were established rapidly, there would be a Galactic loss of individuality and my own loss would be part of an unimaginably greater whole. I would, however, certainly never consent to lose my individuality while the rest of the Galaxy retains theirs.”
Daneel said, “It is, then, as I thought. Your brain would not merge well and, in any case, it would serve a better purpose if you retained an independent judgmental ability.”
“When did you change your mind? You said that it was for merging that you brought me here.”
“Yes, and only by using the fullest extent of my greatly diminished powers. Still, when I said, ‘That is why I have brought you here,’ please remember that in Galactic Standard, the word ‘you’ represents the plural as well as the singular. I was referring to all of you.”
Pelorat stiffened in his seat. “Indeed? Tell me then, Daneel, would a human brain that was merged with your brain share in all your memories—all twenty thousand years of it, back to legendary times?”
“Certainly, sir.”
Pelorat drew a long breath. “That would fulfill a lifetime search, and it is something I would gladly give up my individuality for. Please let me have the privilege of sharing your brain.”
Trevize asked softly, “And Bliss? What about her?”
Pelorat hesitated for no more than a moment. “Bliss will understand,” he said. “She will, in any case, be better off without me—after a while.”
Daneel shook his head. “Your offer, Dr. Pelorat, is a generous one, but I cannot accept it. Your brain is an old one and it cannot survive for more than two or three decades at best, even in a merger with my own. I need something else. —See!” He pointed and said, “I’ve called her back.”
Bliss was returning, walking happily, with a bounce to her steps.
Pelorat rose convulsively to his feet. “Bliss! Oh no!”
“Do not be alarmed, Dr. Pelorat,” said Daneel. “I cannot use Bliss. That would merge me with Gaia, and I must remain independent of Gaia, as I have already explained.”
“But in that case,” said Pelorat, “who—”
And Trevize, looking at the slim figure running after Bliss, said, “The robot has wanted Fallom all along, Janov.”
103.
BLISS RETURNED, SMILING, CLEARLY IN A STATE of great pleasure.
“We couldn’t pass beyond the bounds of the estate,” she said, “but it all reminded me very much of Solaria. Fallom, of course, is convinced it is Solaria. I asked her if she didn’t think that Daneel had an appearance different from that of Jemby—after all, Jemby was metallic—and Fallom said, ‘No, not really.’ I don’t know what she meant by ‘not really.’ ”
She looked across to the middle distance where Fallom was now playing her flute for a grave Daneel, whose head nodded in time. The sound reached them, thin, clear, and lovely.
“Did you know she took the flute with her when we left the ship?” asked Bliss. “I suspect we won’t be able to get her away from Daneel for quite a while.”
The remark was met with a heavy silence, and Bliss looked at the two men in quick alarm. “What’s the matter?”
Trevize gestured gently in Pelorat’s direction. It was up to him, the gesture seemed to say.
Pelorat cleared his throat and said, “Actually, Bliss, I think that Fallom will be staying with Daneel permanently.”
“Indeed?” Bliss, frowning, made as though to walk in Daneel’s direction, but Pelorat caught her arm. “Bliss dear, you can’t. He’s more powerful than Gaia even now, and Fallom must stay with him if Galaxia is to come into existence. Let me explain—and, Golan, please correct me if I get anything wrong.”
Bliss listened to the account, her expression sinking into something close to despair.
Trevize said, in an attempt at cool reason, “You see how it is, Bliss. The child is a Spacer and Daneel was designed and put together by Spacers. The child was brought up by a robot and knew nothing else on an estate as empty as this one. The child has transductive powers which Daneel will need, and she will live for three or four centuries, which may be what is required for the construction of Galaxia.”
Bliss said, her cheeks flushed and her eyes moist, “I suppose that the robot maneuvered our trip to Earth in such a way as to make us pass through Solaria in order to pick up a child for his use.”
Trevize shrugged. “He may simply have taken advantage of the opportunity. I don’t think his powers are strong enough at the moment to make complete puppets of us at hyperspatial distances.”
“No. It was purposeful. He made certain that I would feel strongly attracted to the child so that I would take her with me, rather than leave her to be killed; that I would protect her even against you when you showed nothing but resentment and annoyance at her being with us.”
Trevize said, “That might just as easily have been your Gaian ethics, which Daneel could have strengthened a bit, I suppose. Come, Bliss, there’s nothing to be gained. Suppose you could take Fallom away. Where could you then take her that would make her as happy as she is here? Would you take her back to Solaria where she would be killed quite pitilessly; to some crowded world where she would sicken and die; to Gaia, where she would wear her heart out longing for Jemby; on an endless voyage through the Galaxy, where she would think that every world we came across was her Solaria? And would you find a substitute for Daneel’s use so that Galaxia could be constructed?”
Bliss was sadly silent.
Pelorat held out his hand to her, a bit timidly. “Bliss,” he said, “I volunteered to have my brain fused with Daneel’s. He wouldn’t take it because he said I was too old. I wish he had, if that would have saved Fallom for you.”
Bliss took his hand and kissed it. “Thank you, Pel, but the price would be too high, even for Fallom.” She took a deep breath, and tried to smile. “Perhaps, when we get back to Gaia, room will be found in the global organism for a child for me—and I will place Fallom in the syllables of its name.”
And now Daneel, as though aware that the matter was settled, was walking toward them, with Fallom skipping along at his side.
The youngster broke into a run and reached them first. She said to Bliss, “Thank you, Bliss, for taking me home to Jemby again and for taking care of me while we were on the ship. I shall always remember you.” Then she flung herself at Bliss and the two held each other tightly.
“I hope you will always be happy,” said Bliss. “I will remember you, too, Fallom dear,” and released her with reluctance.
Fallom turned to Pelorat, and said, “Thank you, too, Pel, for letting me read your
book-films.” Then, without an additional word, and after a trace of hesitation, the thin, girlish hand was extended to Trevize. He took it for a moment, then let it go.
“Good luck, Fallom,” he muttered.
Daneel said, “I thank you all, sirs and madam, for what you have done, each in your own way. You are free to go now, for your search is ended. As for my own work, it will be ended, too, soon enough, and successfully now.”
But Bliss said, “Wait, we are not quite through. We don’t know yet whether Trevize is still of the mind that the proper future for humanity is Galaxia, as opposed to a vast conglomeration of Isolates.”
Daneel said, “He has already made that clear a while ago, madam. He has decided in favor of Galaxia.”
Bliss’s lips tightened. “I’d rather hear that from him. —Which is it to be, Trevize?”
Trevize said calmly, “Which do you want it to be, Bliss? If I decide against Galaxia, you may get Fallom back.”
Bliss said, “I am Gaia. I must know your decision, and its reason, for the sake of the truth and nothing else.”
Daneel said, “Tell her, sir. Your mind, as Gaia is aware, is untouched.”
And Trevize said, “The decision is for Galaxia. There is no further doubt in my mind on that point.”
104.
BLISS REMAINED MOTIONLESS FOR THE TIME ONE might take to count to fifty at a moderate rate, as though she were allowing the information to reach all parts of Gaia, and then she said, “Why?”
Trevize said, “Listen to me. I knew from the start that there were two possible futures for humanity—Galaxia, or else the Second Empire of Seldon’s Plan. And it seemed to me that those two possible futures were mutually exclusive. We couldn’t have Galaxia unless, for some reason, Seldon’s Plan had some fundamental flaw in it.
