"No. I'm glad to see you again, Philip. After so long. I'm sorry your marriage didn't work out."

"How have you been?"

"I've been very ill. I'm afraid that my moment on the world's stage has almost ended." The ancient eyes studied the younger man reflectively. "You look as if you have been doing well. Like everyone else I thought highly of. You've gone to the top in this society."

Kramer smiled. Then he became serious. "Professor, there's a project we're working on that I want to talk to you about. It's the first ray of hope we've had in this whole war. If it works, we may be able to crack the yuk defenses, get some ships into their system. If we can do that the war might be brought to an end."

"Go on. Tell me about it, if you wish."

"It's a long shot, this project. It may not work at all, but we have to give it a try."

"It's obvious that you came here because of it," Professor Thomas murmured. "I'm becoming curious. Go on."

After Kramer finished the old man lay back in the bed without speaking. At last he sighed.

"I understand. A human mind, taken out of a human body." He sat up a little, looking at Kramer. "I suppose you're thinking of me."

Kramer said nothing.

"Before I make my decision I want to see the papers on this, the theory and outline of construction. I'm not sure I like it.--For reasons of my own, I mean. But I want to look at the material. If you'll do that--"

"Certainly." Kramer stood up and went to the door. Gross and the two Security Agents were standing outside, waiting tensely. "Gross, come inside."

They filed into the room.

"Give the Professor the papers," Kramer said. "He wants to study them before deciding."

Gross brought the file out of his coat pocket, a manila envelope. He handed it to the old man on the bed. "Here it is, Professor. You're welcome to examine it. Will you give us your answer as soon as possible? We're very anxious to begin, of course."

"I'll give you my answer when I've decided." He took the envelope with a thin, trembling hand. "My decision depends on what I find out from these papers. If I don't like what I find, then I will not become involved with this work in any shape or form." He opened the envelope with shaking hands. "I'm looking for one thing."

"What is it?" Gross said.

"That's my affair. Leave me a number by which I can reach you when I've decided."

Silently, Gross put his card down on the dresser. As they went out Professor Thomas was already reading the first of the papers, the outline of the theory.

Kramer sat across from Dale Winter, his second in line. "What then?"

Winter said.

"He's going to contact us." Kramer scratched with a drawing pen on some paper. "I don't know what to think."

"What do you mean?" Winter's good-natured face was puzzled.

"Look." Kramer stood up, pacing back and forth, his hands in his uniform pockets. "He was my teacher in college. I respected him as a man, as well as a teacher. He was more than a voice, a talking book.

He was a person, a calm, kindly person I could look up to. I always wanted to be like him, someday. Now look at me."

"So?"

"Look at what I'm asking. I'm asking for his life, as if he were some kind of laboratory animal kept around in a cage, not a man, a teacher at all."

"Do you think he'll do it?"

"I don't know." Kramer went to the window. He stood looking out. "In a way, I hope not."

"But if he doesn't--"

"Then we'll have to find somebody else. I know. There would be somebody else. Why did Dolores have to--"

The vidphone rang. Kramer pressed the b.u.t.ton.

"This is Gross." The heavy features formed. "The old man called me.

Professor Thomas."

"What did he say?" He knew; he could tell already, by the sound of Gross' voice.

"He said he'd do it. I was a little surprised myself, but apparently he means it. We've already made arrangements for his admission to the hospital. His lawyer is drawing up the statement of liability."

Kramer only half heard. He nodded wearily. "All right. I'm glad. I suppose we can go ahead, then."

"You don't sound very glad."

"I wonder why he decided to go ahead with it."

"He was very certain about it." Gross sounded pleased. "He called me quite early. I was still in bed. You know, this calls for a celebration."

"Sure," Kramer said. "It sure does."

Toward the middle of August the project neared completion. They stood outside in the hot autumn heat, looking up at the sleek metal sides of the ship.

Gross thumped the metal with his hand. "Well, it won't be long. We can begin the test any time."

"Tell us more about this," an officer in gold braid said. "It's such an unusual concept."

"Is there really a human brain inside the ship?" a dignitary asked, a small man in a rumpled suit. "And the brain is actually alive?"

"Gentlemen, this ship is guided by a living brain instead of the usual Johnson relay-control system. But the brain is not conscious. It will function by reflex only. The practical difference between it and the Johnson system is this: a human brain is far more intricate than any man-made structure, and its ability to adapt itself to a situation, to respond to danger, is far beyond anything that could be artificially built."

Gross paused, c.o.c.king his ear. The turbines of the ship were beginning to rumble, shaking the ground under them with a deep vibration. Kramer was standing a short distance away from the others, his arms folded, watching silently. At the sound of the turbines he walked quickly around the ship to the other side. A few workmen were clearing away the last of the waste, the sc.r.a.ps of wiring and scaffolding. They glanced up at him and went on hurriedly with their work. Kramer mounted the ramp and entered the control cabin of the ship. Winter was sitting at the controls with a Pilot from s.p.a.ce-transport.

"How's it look?" Kramer asked.

"All right." Winter got up. "He tells me that it would be best to take off manually. The robot controls--" Winter hesitated. "I mean, the built-in controls, can take over later on in s.p.a.ce."
