"Bad," he said. "What do we do?"

"I think our course is plain before us. We want psychohistory-'

"Yes, we do," said the General. "Seldon told me something about taxation that- But never mind. That is beside the point at the moment. Go on."

Linn, who, in his troubled state of mind, had allowed a small fragment of impatience to show on his face, continued, "As I say, we want psychohistory without Seldon. He is, in any case, a used-up man. The more I study him, the more I see an elderly scholar who is living on his past deeds. He has had nearly thirty years to make a success of psychohistory and he has failed. Without him, with new men at the helm, psychohistory may advance more rapidly."

"Yes, I agree. Now what about the woman?"

"Well, there you are. We haven't taken her into consideration because she has been careful to remain in the background. But I strongly suspect now that it will be difficult, perhaps impossible, to remove Seldon quietly and without implicating the government, as long as the woman remains alive."

"Do you really believe that she will mangle you and me-if she thinks we have harmed her man?" said the General, his mouth twisting in contempt.

"I really think she will and that she will start a rebellion as well. It will he exactly as she promised."

"You are turning into a coward."

"General, please. I am trying to be sensible. I'm not backing off. We must take care of this Tiger Woman." He paused thoughtfully. "As a matter of fact, my sources have told me this and I admit to having paid far too little attention to the matter."

"And how do you think we can get rid of her?"

Linn said, "I don't know." Then, more slowly, "But someone else might."

Seldon had had a bad night also, nor was the new day promising to be much better. There weren't too many times when Hari felt annoyed with Dors. But this time, he was very annoyed.

He said, "What a foolish thing to do! Wasn't it enough that we were all staying at the Dome's Edge Hotel? That alone would have been sufficient to drive a paranoid ruler into thoughts of some sort of conspiracy."

"How? We were unarmed, Hari. It was a holiday affair, the final touch of your birthday celebration. We posed no threat."

"Yes, but then you carried out your invasion of the Palace grounds. It was unforgivable. You raced to the Palace to interfere with my session with the General, when I had specifically-and several times-made it plain that I didn't want you there. I had my own plans, you know."

Dors said, "Your desires and your orders and your plans all take second place to your safety. I was primarily concerned about that."

"I was in no danger."

"That is not something I can carelessly a.s.sume. There have been two attempts on your life. What makes you think there won't be a third?"

"The two attempts were made when I was First Minister. I was probably worth killing then. Who would want to kill an elderly mathematician?"

Dors said, "That's exactly what I want to find out and that's what I want to stop. I must begin by doing some questioning right here at the Project."

"No. You will simply be upsetting my people. Leave them alone."

"That's exactly what I can't do. Hari, my job is to protect you and for twenty-eight years I've been working at that. You cannot stop me now."

Something in the blaze of her eyes made it quite clear that, whatever Seldon's desires or orders might be, Dors intended to do as she pleased.

Seldon's safety came first.

"May I interrupt you, Yugo?"

"Of course, Dors," said Yugo Amaryl with a large smile. "You are lover an interruption. What can I do for you?"

"I am trying to find out a few things, Yugo, and I wonder if you would humor me in this."

"If I can."

"You have something in the Project called the Prime Radiant. I hear it now and then. Hari speaks of it, so I imagine I know what it looks like when it is activated, but I have never actually seen it in operation. I would like to."

Amaryl looked uncomfortable. "Actually the Prime Radiant is just about the most closely guarded part of the Project and you aren't on the list of the members who have access."

"I know that, but we've known each other for twenty-eight years-"

"And you're Hari's wife. I suppose we can stretch a point. We only have two full Prime Radiants. There's one in Hari's office and one here. Right there, in fact."

Dors looked at the squat black cube on the central desk. It looked utterly undistinguished. "Is that it?"

"That's it. It stores the equations that describe the future."

"How do you get at those equations?"

Amaryl moved a contact and at once the room darkened and then came to life in a variegated glow. All around Dors were symbols, arrows, mathematical signs of one sort or another. They seemed to be moving, spiraling, but when she focused her eyes on any particular portion, it seemed to be standing still.

She said, "Is that the future, then?"

"It may be," said Amaryl, turning off the instrument. "I had it at full expansion so you could see the symbols. Without expansion, nothing is visible but patterns of light and dark."

"And by studying those equations, you are able to judge what the future holds in store for us?"

"In theory." The room was now back to its mundane appearance. "But there are two difficulties."

"Oh? What are they?"

"To begin with, no human mind has created those equations directly. We have merely spent decades programming more powerful computers and they have devised and stored the equations, but, of course, we don't know if they are valid and have meaning. It depends entirely on how valid and meaningful the programming is in the first place."

"They could be all wrong, then?"

"They could be." Amaryl rubbed his eyes and Dors could not help thinking how old and tired he seemed to have grown in the last couple of years. He was younger than Hari by nearly a dozen years, but he seemed much older.

"Of course," Amaryl went on in a rather weary voice, "we hope that they aren't all wrong, but that's where the second difficulty comes in. Although Hari and I have been testing and modifying them for decades, we can never be sure what the equations mean. The computer has constructed them, so it is to be presumed they must mean something-but what? There are portions that we think we have worked out. In fact, right now, I'm working on what we call Section A-23, a particularly knotty system of relationships. We have not yet been able to match it with anything in the real Universe. Still, each year sees us further advanced and I look forward confidently to the establishment of psychohistory as a legitimate and useful technique for dealing with the future."

"How many people have access to these Prime Radiants?"

"Every mathematician in the Project has access but not at will. There have to be applications and time allotted and the Prime Radiant has to be adjusted to the portion of the equations a mathematician wishes to refer to. It gets a little complicated when everyone wants to use the Prime Radiant at the same time. Right now, things are slow, possibly because we're still in the aftermath of Hari's birthday celebration."

"Is there any plan for constructing additional Prime Radiants?"

Amaryl thrust out his lips. "Yes and no. It would be very helpful if we had a third, but someone would have to be in charge of it. It can't just be a community possession. I have suggested to Hari that Tamwile Elar-you know him, I think-"

"Yes, I do."

"That Elar have a third Prime Radiant. His achaotic equations and the Electro-Clarifier he thought up make him clearly the third man in the Project after Hari and myself. Hari hesitates, however."

"Why? Do you know?"

"If Elar gets one, he is openly recognized as the third man, over the Head of other mathematicians who are older and who have more senior status in the Project. There might be some political difficulties, so to speak. I think that we can't waste time in worrying about internal politics, but Hari- Well, you know Hari."

"Yes, I know Hari. Suppose I tell you that Linn has seen the Prime Radiant."

"Linn?"

"Colonel Hender Linn of the junta. Tennar's lackey."

"I doubt that very much, Dors."

"He has spoken of spiraling equations and I have just seen them produced by the Prime Radiant. I can't help but think he's been here and seen it working."

Amaryl shook his head, "I can't imagine anyone bringing a member of the junta into Hari's office-or mine."

"Tell me, who in the Project do you think is capable of working with the junta in this fashion?"

"No one," said Amaryl flatly and with clearly unlimited faith. "That would be unthinkable. Perhaps Linn never saw the Prime Radiant but was merely told about it."

"Who would tell him about it?"

Amaryl thought a moment and said, "No one."

"Well now, you talked about internal politics a while ago in connection with the possibility of Elar having a third Prime Radiant. I suppose in a Project such as this one with hundreds of people, there are little feuds going on all the time-frictions-quarrels."

"Oh yes. Poor Hari talks to me about it every once in a while. He has to deal with them in one way or another and I can well imagine what a headache it must be for him."

"Are these feuds so bad that they interfere with the working of the Project?"

"Not seriously."

"Are there any people who are more quarrelsome than others or any duo draw more resentment than others? In short, are there people you can get rid of and perhaps remove 90 percent of the friction at the cost of 5 or 6 percent of the personnel?"

Amaryl raised his eyebrows. "It sounds like a good idea, but I don't know whom to get rid of. I don't really partic.i.p.ate in all the minutiae of internal politics. There's no way of stopping it, so for my part, I merely avoid it."

"That's strange," said Dors. "Aren't you in this way denying any credibility to psychohistory?"

"In what way?"

"How can you pretend to reach a point where you can predict and guide the future, when you cannot a.n.a.lyze and correct something as homegrown as personal frictions in the very Project that promises so much?"

Amaryl chuckled softly. It was unusual, for he was not a man who was given to humor and laughter. "I'm sorry, Dors, but you picked on the one problem that we have solved, after a manner of speaking. Hari himself identified the equations that represented the difficulties of personal friction years ago and I myself then added the final touch last year.

"I found that there were ways in which the equations could be changed so as to indicate a reduction in friction. In every such case, however, a reduction in friction here meant an increase in friction there. Never at any time was there a total decrease or, for that matter, a total increase in the friction within a closed group-that is, one in which no old members leave and no new members come in. What I proved, with the help of Elar's achaotic equations, was that this was true despite any conceivable action anyone could take. Hari calls it 'the law of conservation of personal problems.'

"It gave rise to the notion that social dynamics has its conservation laws as physics does and that, in fact, it is these laws that offer us the best possible tools for solving the truly troublesome aspects of psychohistory."

Dors said, "Rather impressive, but what if you end up finding that nothing at all can be changed, that everything that is bad is conserved, and that to save the Empire from destruction is merely to increase destruction of another kind?"

"Actually some have suggested that, but I don't believe it."

"Very well. Back to reality. Is there anything in the frictional problems within the Project that threaten Hari? I mean, with physical harm."

"Harm Hari? Of course not. How can you suggest such a thing?"

"Might there not be some who resent Hari, for being too arrogant, too pushy, too self-absorbed, too eager to grab all the credit? Or, if none of these things apply, might they not resent him simply because he has run the Project for so long a time?"

"I never heard anyone say such a thing about Hari."

Dors seemed dissatisfied. "I doubt that anyone would say such things in your hearing, of course. But thank you, Yugo, for being so helpful and for giving me so much of your time."

Amaryl stared after her as she left. He felt vaguely troubled, but then returned to his work and let other matters drift away.

One way Hari Seldon had (out of not too many ways) for pulling away from his work for a time was to visit Raych's apartment, just outside the university grounds. To do this invariably filled him with love for his foster son. There were ample grounds. Raych had been good, capable, and loyal-but besides that was the strange quality Raych had of inspiring trust and love in others.

Hari had observed it when Raych was a twelve-year-old street boy, who somehow pulled at his own and at Dors's heartstrings. He remembered how Raych had affected Rash.e.l.le, the onetime Mayor of Wye. Hari remembered how Joranum had trusted Raych, which led to his own destruction. Raych had even managed to win the heart of the beautiful Manella. Hari did not completely understand this particular quality that Raych embodied, but he enjoyed whatever contact he had with his foster son.

He entered the apartment with his usual "All well here?"

Raych put aside the holographic material he was working with and rose to greet him, "All well, Dad."
