But Hari's measured gaze stopped him. One thing Leyel had known since they first met at a conference back in their youth was that Hari would not stand for another man's self-deception. They had sat next to each other at a presentation by a demographer who had a considerable reputation at the time. Leyel watched as Hari destroyed the poor man's thesis with a few well-aimed questions. The demographer was furious. Obviously he had not seen the flaws in his own argument-- but now that they had been shown to him, he refused to admit that they were flaws at all.

Afterward, Hari had said to Leyel, "I've done him a favor."

"How, by giving him someone to hate?" said Leyel.

"No. Before, he believed his own unwarranted conclusions. He had deceived himself.

Now he doesn't believe them."

"But he still propounds them."

"So now he's more of a liar and less of a fool. I have improved his private integrity. His public morality I leave up to him."

Leyel remembered this and knew that if he told Hari he could give up Deet for any reason, even to join the Foundation, it would be worse than a lie. It would be foolishness.

"It's a terrible thing you've done," said Leyel. "You know that Deet is part of myself. I can't give her up to join your Foundation. But now for the rest of our lives together I'll know that I could have gone, if not for her. You've given me wormwood and gall to drink, Hari."

Hari nodded slowly. "I hoped that when you read my note you'd realize I didn't want to tell you more. I hoped you wouldn't come to me and ask. I can't lie to you, Leyel. I wouldn't if I could. But I did withhold information, as much as possible.

To spare us both problems."

"It didn't work."

"It isn't Deet's fault, Leyel. It's who she is. She belongs on Trantor, not on Terminus. And you belong with her. It's a fact, not a decision. We'll never discuss this again."

"No," said Leyel.

They sat there for a long minute, gazing steadily at each other. Leyel wondered if he and Hari would ever speak again. No. Never again. I don't ever want to see you again, Hari Seldon. You've made me regret the one unregrettable decision of my life-- Deet. You've made me wish, somewhere in my heart, that I'd never married her.

Which is like making me wish I'd never been born.

Leyel got up from his chair and left the room without a word. When he got outside, he turned to the reception room in general, where several people were waiting to see Seldon. "Which of you are mine?" he asked.

Two women and one man stood up immediately.

"Fetch me a secure car and a driver."

Without a glance at each other, one of them left on the errand. The others fell in step beside Leyel. Subtlety and discretion were over for the moment. Leyel had no wish to mingle with the people of Trantor now. He only wanted to go home.

Hari Seldon left his office by the back way and soon found his way to Chandrakar Matt's cubicle in the Department of Library Relations. Chanda looked up and waved, then effortlessly slid her chair back until it was in the exact position required.

Hari picked up a chair from the neighboring cubicle and, again without showing any particular care, set it exactly where it had to be.

Immediately the computer installed inside Chanda's lector recognized the configuration. It recorded Hari's costume of the day from three angles and superimposed the information on a long-stored holoimage of Chanda and Hari conversing pleasantly. Then, once Hari was seated, it began displaying the hologram.

The hologram exactly matched the positions of the real Hari and Chanda, so that infrared sensors would show no discrepancy between image and fact. The only thing different was the faces-- the movement of lips, blinking of eyes, the expressions.

Instead of matching the words Hari and Chanda were actually saying, they matched the words being pushed into the air outside the cubicle-- a harmless, randomly chosen series of remarks that took into account recent events so that no one would suspect that it was a canned conversation.

It was one of Hari's few opportunities for candid conversation that the Pubs would not overhear, and he and Chanda protected it darefully. They never spoke long enough or often, enough that the Pubs would wonder at their devotion to such empty conversations. Much of their communication was subliminal-- a sentence would stand for a paragraph, a word for a sentence, a gesture for a word. But when the conversation was done, Chanda knew where to go from there, what to do next; and Hari was reassured that his most important work was going on behind the smokescreen of the Foundation.

"For a moment I thought he might actually leave her."

"Don't underestimate the lure of the Encyclopedia."

"I fear I've wrought too well, Chanda. Do you think someday the Encyclopedia Galactica might actually exist?"

"It's a good idea. Good people are inspired by it. It wouldn't serve its purpose if they weren't. What should I tell Deet?"

"Nothing, Chanda. The fact that Leyel is staying that's enough for her."

"If he changes his mind, will you actually let him go to Terminus?"

"If he changes his mind, then he must go, because if he would leave Deet, he's not the man for us."

"Why not just tell him? Invite him?"

"He must become part of the Second Foundation without realizing it. He must do it by natural inclination, not by a summons from me, and above all not by his own ambition."

"Your standards are so high, Hari, it's no wonder so few measure up. Most people in the Second Foundation don't even know that's what it is. They think they're librarians. Bureaucrats. They think Deet is an anthropologist who works among them in order to study them."

"Not so. They once thought that, but now they think of Deet as one of them. As one of the best of them. She's defining what it means to be a librarian. She's making them proud of the name."

"Aren't you ever troubled, Hari, by the fact that in the practice of your art--"

"My science."

"Your meddlesome magical craft, you old wizard, you don't fool me with all ypur talk of science. I've seen the scripts of the holographs you're preparing for the vault on Terminus."

"That's all a pose."

"I can just imagine you saying those words. Looking perfectly satisfied with yourself. 'If you care to smoke, I wouldn't mind... Pause for chuckle... Why should I? I'm not really here.' Pure showmanship."

Hari waved off the idea. The computer quickly found a bit of dialogue to fit his gesture, so the false scene would not seem false. "No, I'm not troubled by the fact that in the practice of my science I change the lives of human beings. Knowledge has always changed people's lives. The only difference is that I know I'm changing them-- and the changes I introduce are planned, they're under control. Did the man who invented the first artificial light-- what was it, animal fat with a wick? A

light-emitting diode? --did he realize what it would do to humankind, to be given power over night?"

As always, Chanda deflated him the moment he started congratulating himself. "In the first place, it was almost certainly a woman, and in the second place, she knew exactly what she was doing. It allowed her to find her way through the house at night. Now she could put her nursing baby in another bed, in another room, so she could get some sleep at night without fear of rolling over and smothering the child."

Hari smiled. "If artificial light was invented by a woman, it was certainly a prostitute, to extend her hours of work."

Chanda grinned. She did not laugh-- it was too hard for the computer to come up with jokes to explain laughter. "We'll watch Leyel carefully, Hari. How will we know when he's ready, so we can begin to count on him for protection and leadership?"
