He set the computer to move the ship out of the planetary plane as well, since that would make it possible to accelerate with greater safety. They would then more quickly reach a region where space curvature would be low enough to make the Jump secure.

And, as often on such occasions, he fell to studying the stars. They were almost hypnotic in their quiet changelessness. All their turbulence and instability were wiped out by the distance that left them only dots of light.

One of those dots might well be the sun about which Earth revolved-the original sun, under whose radiation life began, and under whose beneficence humanity evolved.

Surely, if the Spacer worlds circled stars that were bright and prominent members of the stellar family, and that were nevertheless unlisted in the computer's Galactic map, the same might be true of the sun.

Or was it only the suns of the Spacer worlds that were omitted because of some primeval treaty agreement that left them to themselves? Would Earth's sun be included in the Galactic map, but not marked off from the myriads of stars that were sun-like, yet had no habitable planet in orbit about itself?

There were after all, some thirty billion sun-like stars in the Galaxy, and only about one in a thousand had habitable planets in orbits about them. There might be a thousand such habitable planets within a few hundred parsecs of his present position. Should he sift through the sun-like stars one by one, searching for them?

Or was the original sun not even in this region of the Galaxy? How many other regions were convinced the sun was one of their neighbors, that they were primeval Settlers-?

He needed information, and so far he had none.

He doubted strongly whether even the closest examination of the millennial ruins on Aurora would give information concerning Earth's location. He doubted even more strongly that the Solarians could be made to yield information.

Then, too, if all information about Earth had vanished out of the great Library at Trantor; if no information about Earth remained in the great Collective Memory of Gaia; there seemed little chance that any information that might have existed on the lost worlds of the Spacers would have been overlooked.

And if he found Earth's sun and, then, Earth itself, by the sheerest good fortune-would something force him to be unaware of the fact? Was Earth's defense absolute? Was its determination to remain in hiding unbreakable?

What was he looking for anyway?

Was it Earth?. Or was it the flaw in Seldon's Plan that he thought (for no clear reason) he might find on Earth?

Seldon's Plan had been working for five centuries now, and would bring the human species (so it was said) to safe harbor-at last in the womb of a Second Galactic Empire, greater than the First, a nobler and a freer one-and yet he, Trevize, had voted against it, and for Galaxia.

Galaxia would be one large organism, while the Second Galactic Empire would, however great in size and variety, be a mere union of individual organisms of microscopic size in comparison with itself. The Second Galactic Empire would be another example of the kind of union of individuals that humanity had set up ever since it became humanity. The Second Galactic Empire might be the largest and best of the species, but it would still be but one more member of that species.

For Galaxia, a member of an entirely different species of organization, to be better than the Second Galactic Empire, there must be a flaw in the Plan, something the great Hari Seldon had himself overlooked.

But if it were something Seldon had overlooked, how could Trevize correct the matter? He was not a mathematician; knew nothing, absolutely nothing, about the details of the Plan; would understand nothing, furthermore, even if it were explained to him.

All he knew were the assumptions-that a great number of human beings be involved and that they not be aware of the conclusions reached. The first assumption was self-evidently true, considering the vast population of the Galaxy, and the second had to be true since only the Second Foundationers knew the details of the Plan, and they kept it to themselves securely enough.

That left an added unacknowledged assumption, a taken-for-granted assumption, one so taken for granted it was never mentioned nor thought of-and yet one that might be false. An assumption that, if it were false, would alter the grand conclusion of the Plan and make Galaxia preferable to Empire.

But if the assumption was so obvious and so taken for granted that it was never even expressed, how could it be false? And if no one ever mentioned it, or thought of it, how could Trevize know it was there, or have any idea of its nature even if he guessed its existence?

Was he truly Trevize, the man with the flawless intuition-as Gaia insisted? Did he know the right thing to do even when he didn't know why he. was doing it?

Now he was visiting every Spacer world he knew about. Was that the right thing to do? Did the Spacer worlds hold the answer? Or at least the beginning of the answer?

What was there on Aurora but ruins and wild dogs? (And, presumably, other feral creatures. Raging bulls? Overgrown rats? Stalking green-eyed cats?) Solaria was alive, but what was there on it but robots and energy-transducing human beings? What had either world to do with Seldon's Plan unless they contained the secret of the location of the Earth?

And if they did, what had Earth to do with Seldon's Plan? Was this all madness? Had he listened too long and too seriously to the fantasy of his own infallibility?

An overwhelming weight of shame came over him and seemed to press upon him to the point where he could barely breathe. He looked at the stars remote, uncaring-and thought: I must be the Great Fool of the Galaxy.

BLISS'S voice broke in on him. “Well, Trevize, why do you want to see—is anything wrong?” Her voice had twisted into sudden concern.

Trevize looked up and, for a moment, found it momentarily difficult to brush away his mood. He stared at her, then said, “No, no. Nothing's wrong. I-I was merely lost in thought. Every once in a while, after all, I find myself thinking.”.

He was uneasily aware that Bliss could read his emotions. He had only her word that she was voluntarily abstaining from any oversight of his mind.

She seemed to accept his statement, however. She said, “Pelorat is with Fallom, teaching it Galactic phrases. The child seems to eat what we do without undue objection. But what do you want to see me about?”

“Well, not here,”, said Trevize. “The computer doesn't need me at the moment. If you want to come into my room, the bed's made and you can sit on it while I sit on the chair. Or vice versa, if you prefer.”

“It doesn't matter.” They walked the short distance to Trevize's room. She eyed him narrowly. “You don't seem furious anymore.”

“Checking my mind?”

“Not at all. Checking your face.”

“I'm not furious. I may lose my temper momentarily, now and then, but that's not the same as furious. If you don't mind, though, there are questions I must ask you.”

Bliss sat down on Trevize's bed, holding herself erect, and with a solemn expression on her wide-cheeked face and in her dark brown eyes. Her shoulder-length black hair was neatly arranged and her slim hands were clasped loosely in her lap. There was a faint trace of perfume about her.

Trevize smiled. “You've dolled yourself up. I suspect you think I won't yell quite so hard at a young and pretty girl.”

“You can yell and scream all you wish if it will make you feel better. I just don't want you yelling and screaming at Fallom.”

“I don't intend to. In fact, I don't intend to yell and scream at you. Haven't we decided to be friends?”

“Gaia has never had anything but feelings of friendship toward you, Trevize.”

“I'm not talking about Gaia. I know you're part of Gaia and that you are Gaia. Still there's part of you that's an individual, at least after a fashion. I'm talking to the individual. I'm talking to someone named Bliss without regard or with as little regard as possible-to Gaia. Haven't we decided to be friends, Bliss?”

“Yes, Trevize.”

“Then how is it you delayed dealing with the robots on Solaria after we had left the mansion and reached the ship? I was humiliated and physically hurt, yet you did nothing. Even though every moment might bring additional robots to the scene and the number might overwhelm us, you did nothing.”

Bliss looked at him seriously, and spoke as though she were intent on explaining her actions rather than defending them. “I was not doing nothing, Trevize. I was studying the Guardian Robots' minds, and trying to learn how to handle them.”

“I know that's what you were doing. At least you said you were at the time. I just don't see the sense of it. Why handle the minds when you were perfectly capable of destroying them-as you finally did?”

“Do you think it so easy to destroy an intelligent being?”

Trevize's lips twisted into an expression of distaste. “Come, Bliss. An intelligent being? It was just a robot.”

“Just a robot?” A little passion entered her voice. “That's the argument always. Just. Just! Why should the Solarian, Bander, have hesitated to kill us? We were just human beings without transducers. Why should there be any hesitation about leaving Fallom to its fate? It was just a Solarian, and an immature specimen at that. If you start dismissing anyone or anything you want to do away with as just a this or just a that, you can destroy anything you wish. There are always categories you can find for them.”

Trevize said, “Don't carry a perfectly legitimate remark to extremes just to make it seem ridiculous. The robot was just a robot. You can't deny that. It was not human. It was not intelligent in our sense. It was a machine mimicking an appearance of intelligence.”

Bliss said, “How easily you can talk when you know nothing about it. I am Gaia. Yes, I am Bliss, too, but I am Gaia. I am a world that finds every atom of itself precious and meaningful, and every organization of atoms even more precious and meaningful. I/we/Gaia would not lightly break down an organization, though we would gladly build it into something still more complex, provided always that that would not harm the whole.

“The highest form of organization we know produces intelligence, and to be willing to destroy intelligence requires the sorest need. Whether it is machine intelligence or biochemical intelligence scarcely matters. In fact, the Guardian Robot represented a kind of intelligence I/we/Gaia had never encountered. To study it was wonderful. To destroy it, unthinkable-except in a moment of crowning emergency.”

Trevize said dryly, “There were three greater intelligences at stake: your own, that of Pelorat, the human being you love, and, if you don't mind my mentioning it, mine.”

“Four! You still keep forgetting to include Fallom. They were not yet at stake. So I judged. See here! Suppose you were faced with a painting, a great artistic masterpiece, the existence of which meant death to you. All you had to do was to bring a wide brush of paint slam-bang, and at random, across the face of that painting and it would be destroyed forever, and you would be safe. But suppose, instead, that if you studied the painting carefully, and added just a touch of paint here, a speck there, scraped off a minute portion in a third place, and so on, you would alter the painting enough to avoid death, and yet leave it a masterpiece. Naturally, the revision couldn't be done except with the most painstaking care. It would take time, but surely, if that time existed, you would try to save the painting as well as your life.”

Trevize said, “Perhaps. But in the end you destroyed the painting past redemption. The wide paintbrush came down and wiped out-all the wonderful little touches of color and subtleties of form and shape. And you did that instantly when a little hermaphrodite was at risk, where our danger and your own had not moved you.”

“We Outworlders were still not at immediate risk, while Fallom, it seemed to me, suddenly was. I had to choose between the Guardian Robots and Fallom, and, with no time to lose, I had to choose Fallom.”

“Is that what it was, Bliss? A quick calculation weighing one mind against another, a quick judging of the greater complexity and the greater worth?”

“Yes.”

Trevize said, “Suppose I tell you, it was just a child that was standing before you, a child threatened with death. An instinctive maternalism gripped you then, and you saved it where earlier you were all calculation when only three adult lives were at stake.”

Bliss reddened slightly. “There might have been something like that in it; but it was not after the fashion of the mocking way in which you say it. It had rational thought behind it, too.”

“I wonder. If there had been rational thought behind it, you might have considered that the child was meeting the common fate inevitable in its own society. Who knows how many thousands of children had been cut down to maintain the low number these Solarians think suitable to their world?”

“There's more to it than that, Trevize. The child would be killed because it was too young to be a Successor, and that was because it had a parent who had died prematurely, and that was because I had killed that parent.”

“At a time when it was kill or be killed.”

“Not important. I killed the parent. I could not stand by and allow the child to be killed for my deed. Besides, it offers for study a brain of a kind that has never been studied by Gaia.”

“A child's brain.”

“It will not remain a child's brain. It will further develop the two transducer-lobes on either side of the brain. Those lobes give a Solarian abilities that all of Gaia cannot match. Simply to keep a few lights lit, just to activate a device to open a door, wore me out. Bander could have kept all the power going over an estate as great in complexity and greater in size than that city we saw on Comporellon-and do it even while sleeping.”

Trevize said, “Then you see the child as an important bit of fundamental brain research.”

“In a way, yes.”

“That's not the way I feel. To me, it seems we have taken danger aboard. Great danger.”

“Danger in what way? It will adapt perfectly-with my help. It is highly intelligent, and already shows signs of feeling affection for us. It will eat what we eat, go where we go, and I/we/Gala will gain invaluable knowledge concerning its brain.”

“What if it produces young? It doesn't need a mate. It is its own mate.”

“It won't be of child-bearing age for many years. The Spacers lived for centuries and the Solarians had no desire to increase their numbers. Delayed reproduction is probably bred into the population. Fallom will have no children for a long time.”

“How do you know this?”

“I don't know it. I'm merely being logical.”

“And I tell you Fallom will prove dangerous.”

“You don't know that. And you're not being logical, either.”

“I feel it Bliss, without reason. At the moment. And it is you, not I, who insists my intuition is infallible.”

And Bliss frowned and looked uneasy.

PELORAT paused at the door to the pilot-room and looked inside in a rather ill-at-ease manner. It was as though he were trying to decide whether Trevize was hard at work or not.

Trevize had his hands on the table, as he always did when he made himself part of the computer, and his eyes were on the viewscreen. Pelorat judged, therefore, he was at work, and he waited patiently, trying not to move or, in any way, disturb the other.

Eventually, Trevize looked up at Pelorat. It was not a matter of total awareness. Trevize's eyes always seemed a bit glazed and unfocused when he was in computer-communion, as though he were looking, thinking, living in some other way than a person usually did.

But he nodded slowly at Pelorat, as though the sight, penetrating with difficulty, did, at last, sluggishly impress itself on the optic lobes. Then, after a while, he lifted his hands and smiled and was himself again.

Pelorat said apologetically, “I'm afraid I'm getting in your way, Golan.” “Not seriously, Janov. I was just testing to see if we were ready for the Jump. We are, just about, but I think I'll give it a few more hours, just for luck.”

“Does luck-or random factors-have anything to do with it?”

“An expression only,” said Trevize, smiling, “but random factors do have something to do with it, in theory. What's on your mind?”

“May I sit down?”

“Surely, but let's go into my room. How's Bliss?”

“Very well.” He cleared his throat. “She's sleeping again. She must have her sleep, you understand.”

“I understand perfectly. It's the hyperspatial separation.”

“Exactly, old chap.”

“And Fallom?” Trevize reclined on the bed, leaving Pelorat the chair.

“Those books out of my library that you had your computer print up for me? The folk tales? It's reading them. Of course, it understands very little Galactic, but it seems to enjoy sounding out the words. He's-I keep wanting to use the masculine pronoun for it. Why do you suppose that is, old fellow?”

Trevize shrugged. “Perhaps because you're masculine yourself.”

“Perhaps. It's fearfully intelligent, you know.”

“I'm sure.”

Pelorat hesitated. “I gather you're not very fond of Fallom.”

“Nothing against it personally, Janov. I've never had children and I've never been particularly fond of them generally. You've had children, I seem to remember.”

“One son. It was a pleasure, I recall, having my son when he was a little boy. Maybe that's why I want to use the masculine pronoun for Fallom. It takes me back a quarter of a century or so.”

“I've no objection to your liking it, Janov.”

“You'd like him, too, if you gave yourself a chance.”

“I'm sure I would, Janov, and maybe someday I will give myself a chance to do so.”

Pelorat hesitated again. “I also know that you must get tired of arguing with Bliss.”

“Actually, I don't think we'll be arguing much, Janov. She and I are actually getting along quite well. We even had a reasonable discussion just the other day-no shouting, no recrimination-about her delay in inactivating the Guardian Robots. She keeps saving our lives, after all, so I can't very well offer her less than friendship, can I?”

“Yes, I see that, but I don't mean arguing, in the sense of quarreling. I mean this constant wrangle about Galaxia as opposed to individuality.”

“Oh, that! I suppose that will continue-politely.”

“Would you mind, Golan, if I took up the argument on her behalf?”

“Perfectly all right. Do you accept the idea of Galaxia on your own, or is it that you simply feel happier when you agree with Bliss?”

“Honestly, on my own. I think that Galaxia is what should be forthcoming. You yourself chose that course of action and I am constantly becoming more convinced that that is correct.”

“Because I chose it? That's no argument. Whatever Gaia says, I may be wrong, you know. So don't let Bliss persuade you into Galaxia on that basis.”

“I don't think you are wrong. Solaria showed me that, not Bliss.”

“How?”

“Well, to begin with, we are Isolates, you and L”

“Her term, Janov. I prefer to think of us as individuals.”

“A matter of semantics, old chap. Call it what you will, we are enclosed in our private skins surrounding our private thoughts, and we think first and foremost of ourselves. Self-defense is our first law of nature, even if that means harming everyone else in existence.”

“People have been known to give their lives for others.”

“A rare phenomenon. Many more people have been known to sacrifice the dearest needs of others to some foolish whim of their own.”

“And what has that to do with Solaria?”

“Why, on Solaria, we see what Isolates-or individuals, if you prefer-can become. The Solarians can hardly bear to divide a whole world among themselves. They consider living a life of complete isolation to be perfect liberty.

They have no yearning for even their own offspring, but kill them if there are too many. They surround themselves with robot slaves to which they supply the power, so that if they die, their whole huge estate symbolically dies as well. Is this admirable, Golan? Can you compare it in decency, kindness, and mutual concern with Gaia? Bliss has not discussed this with me at all. It is my own feeling.”

Trevize said, “And it is like you to have that feeling, Janov. I share it. I think Solarian society is horrible, but it wasn't always like that. They are descended from Earthmen, and, more immediately, from Spacers who lived a much more normal life. The Solarians chose a path, for one reason or another, which led to an extreme, but you can't judge by extremes. In all the Galaxy, with its millions of inhabited worlds, is there one you know that now, or in the past, has had a society like that of Solaria, or even remotely like that of Solaria? And would even Solaria have such a society if it were not riddled with robots? Is it conceivable that a society of individuals could evolve to such a pitch of Solarian horror without robots?”

Pelorat's face twitched a little. “You punch holes in everything, Golan or at least I mean you don't ever seem to be at a loss in defending the type of Galaxy you voted against.”

“I won't knock down everything. There is a rationale for Galaxia and when I find it, I'll know it, and I'll give in. Or perhaps, more accurately, if I find it.

“Do you think you might not?”

Trevize shrugged. “How can I say? Do you know why I'm waiting a few hours to make the Jump, and why I'm in danger of talking myself into waiting a few days?”

“You said it would be safer if we waited.”

“Yes, that's what I said, but we'd be safe enough now. What I really fear is that those Spacer worlds for which we have the co-ordinates will fail us altogether. We have only three, and we've already used up two, narrowly escaping death each time. In doing so, we have still not gained any hint as to Earth's location, or even, in actual fact, Earth's existence. Now I face the third and last chance, and what if it, too, fails us?”

Pelorat sighed. “You know there are old folk tales-one, in fact, exists among those I gave Fallom to practice upon-in which someone is allowed three wishes, but only three. Three seems to be a significant number in these things, perhaps because it is the first odd number so that it is the smallest decisive number. You know, two out of three wins. The point is that in these stories, the wishes are of no use. no one ever wishes correctly, which, I have always supposed, is ancient wisdom to the effect that the satisfaction of your wants must be earned, and not...”

He fell suddenly silent and abashed. “I'm sorry, old man, but I'm wasting your time. I do tend to rattle on when I get started on my hobby.”

“I find you always interesting, Janov. I am willing to see the analogy. We have been given three wishes, and we have had two and they have done us no good. Now only one is left. Somehow, I am sure of failure again and so I wish to postpone it. That is why I am putting off the Jump as long as possible.”

“What will you do if you do fail again? Go back to Gaia? To Terminus?”

“Oh no,” said Trevize in a whisper, shaking his head. “The search must continue-if I only knew how.”

 

 

Chapter 14

Dead Planet

60.

 

TREVIZE felt depressed. What few victories he had had since the search began had never been definitive; they had merely been the temporary staving off of defeat

Now he had delayed the Jump to the third of the Spacer worlds till he had spread his unease to the others. When he finally decided that he simply must tell the computer to move the ship through hyperspace, Pelorat was standing solemnly in the doorway to the pilot-room, and Bliss was just behind him and to one side. Even Fallom was standing there, gazing at Trevize owlishly, while one hand gripped Bliss's hand tightly.

Trevize had looked up from the computer and had said, rather churlishly, “Quite the family group!” but that was only his own discomfort speaking.

He instructed the computer to Jump in such a way as to reenter space at a further distance from the star in question than was absolutely necessary. He told himself that that was because he was learning caution as a result of events on the first two Spacer worlds, but he didn't believe that. Well underneath, he knew, he was hoping that he would arrive. in space at a great enough distance from the star to be uncertain as to whether it did or did not have a habitable planet. That would give him a few more days of in-space travel before he could find out, and (perhaps) have to stare bitter defeat in the face.

So now, with the “family group” watching, he drew a deep breath, held it, then expelled it in a between-the-lips whistle as he gave the computer its final instruction.

The star-pattern shifted in a silent discontinuity and the viewscreen became barer, for he had been taken into a region in which the stars were somewhat sparser. And there, nearly in the center, was a brightly gleaming star.

Trevize grinned broadly, for this was a victory of sorts. After all, the third set of co-ordinates might have been wrong and there might have been no appropriate G-type star in sight. He glanced toward the other three, and said, “That's it. Star number three.”

“Are you sure?” asked Bliss softly.

“Watch!” said Trevize. “I will switch to the equi-centered view in the computer's Galactic map, and if that bright star disappears, it's not recorded on the map, and it's the one we want.”

The computer responded to his command, and the star blinked out without any prior dimming. It was as though it had never been, but the rest of the starfield remained as it was, in sublime indifference.

“We've got it,” said Trevize.

And yet he sent the Far Star forward at little more than half the speed he might easily have maintained. There was still the question of the presence or absence of a habitable planet, and he was in no hurry to find out. Even after three days of approach, there was still nothing to be said about that, either way.

Or, perhaps, not quite nothing. Circling the star was a large gas giant. It was very far from its star and it gleamed a very pale yellow on its daylight side, which they could see, from their position, as a thick crescent.

Trevize did not like its looks, but he tried not to show it and spoke as matter-of-factly as a guidebook. “There's a big gas giant out there,” he said. “It's rather spectacular. It has a thin pair of rings and two sizable satellites that can be made out at the moment.”

Bliss said, “Most systems include gas giants, don't they?”

“Yes, but this is a rather large one. Judging from the distance of its satellites, and their periods of revolution, that gas giant is almost two thousand times as massive as a habitable planet would be.”

“What's the difference?” said Bliss. “Gas giants are gas giants and it doesn't matter what size they are, does it? They're always present at great distances from the star they circle, and none of them are habitable, thanks to their size and distance. We just have to look closer to the star for a habitable planet.”

Trevize hesitated, then decided to place the facts on the table. “The thing is,” he said, “that gas giants tend to sweep a volume of planetary space clean. What material they don't absorb into their own structures will coalesce into fairly large bodies that come to make up their satellite system. They prevent other coalescences at even a considerable distance from themselves, so that the larger the gas giant, the more likely it is to be the only sizable planet of a particular star. There'll just be the gas giant and asteroids.”

“You mean there is no habitable planet here?”

“The larger the gas giant, the smaller the chance of a habitable planet and that gas giant is so massive it is virtually a dwarf star.”

Pelorat said, “May we see it?”

All three now stared at the screen (Fallom was in Bliss's room with the j books).

The view was magnified till the crescent filled the screen. Crossing that crescent a distance above center was a thin dark line, the shadow of the ring system which could itself be seen a small distance beyond the planetary surface as a gleaming curve that stretched into the dark side a short distance before it entered the shadow itself.

Trevize said, “The planet's axis of rotation is inclined about thirty-five degrees to its plane of revolution, and its ring is in the planetary equatorial plane, of course, so that the star's light comes in from below, at this point in its orbit, and casts the ring's shadow well above the equator.”

Pelorat watched raptly. “Those are thin rings.”

“Rather above average size, actually,” said Trevize.
