“It shifted,” Kramer said. “But not enough. The mine was coming along after it, trailing it. It’s the same old story, but I wonder about the contact.”
“Here’s our theory,” the expert said. “We keep looking for contact, a trigger in the pseudopodium. But more likely we’re witnessing a psychological phenomena, a decision without any physical correlative. We’re watching for something that isn’t there. The mine decides to blow up. It sees our ship, approaches, and then decides.”
“Thanks.” Kramer turned to Gross. “Well, that confirms what I’m saying. How can a ship guided by automatic relays escape a mine that decides to explode? The whole theory of mine penetration is that you must avoid tripping the trigger. But here the trigger is a state of mind in a complicated, developed life-form.”
“The belt is fifty thousand miles deep,” Gross added. “It solves another problem for them, repair and maintenance. The damn things reproduce, fill up the spaces by spawning into them. I wonder what they feed on?”
“Probably the remains of our first-line. The big cruisers must be a delicacy. It’s a game of wits, between a living creature and a ship piloted by automatic relays. The ship always loses.” Kramer opened a folder. “I’ll tell you what I suggest.”
“Go on,” Gross said. “I’ve already heard ten solutions today. What’s yours?”
“Mine is very simple. These creatures are superior to any mechanical system, but only because they’re alive. Almost any other life-form could compete with them, any higher life-form. If the yuks can put out living mines to protect their planets, we ought to be able to harness some of our own life-forms in a similar way. Let’s make use of the same weapon ourselves.”
“Which life-form do you propose to use?”
“I think the human brain is the most agile of known living forms. Do you know of any better?”
“But no human being can withstand outspace travel. A human pilot would be dead of heart failure long before the ship got anywhere near Proxima.”
“But we don’t need the whole body,” Kramer said. “We need only the brain.”
“What?”
“The problem is to find a person of high intelligence who would contribute, in the same manner that eyes and arms are volunteered.”
“But a brain….”
“Technically, it could be done. Brains have been transferred several times, when body destruction made it necessary. Of course, to a spaceship, to a heavy outspace cruiser, instead of an artificial body, that’s new.”
The room was silent.
“It’s quite an idea,” Gross said slowly. His heavy square face twisted. “But even supposing it might work, the big question is whose brain?”
It was all very confusing, the reasons for the war, the nature of the enemy. The Yucconae had been contacted on one of the outlying planets of Proxima Centauri. At the approach of the Terran ship, a host of dark slim pencils had lifted abruptly and shot off into the distance. The first real encounter came between three of the yuk pencils and a single exploration ship from Terra. No Terrans survived. After that it was all out war, with no holds barred.
Both sides feverishly constructed defense rings around their systems. Of the two, the Yucconae belt was the better. The ring around Proxima was a living ring, superior to anything Terra could throw against it. The standard equipment by which Terran ships were guided in outspace, the Johnson Control, was not adequate. Something more was needed. Automatic relays were not good enough.
—Not good at all, Kramer thought to himself, as he stood looking down the hillside at the work going on below him. A warm wind blew along the hill, rustling the weeds and grass. At the bottom, in the valley, the mechanics had almost finished; the last elements of the reflex system had been removed from the ship and crated up.
All that was needed now was the new core, the new central key that would take the place of the mechanical system. A human brain, the brain of an intelligent, wary human being. But would the human being part with it? That was the problem.
Kramer turned. Two people were approaching him along the road, a man and a woman. The man was Gross, expressionless, heavy-set, walking with dignity. The woman was—He stared in surprise and growing annoyance. It was Dolores, his wife. Since they’d separated he had seen little of her….
“Kramer,” Gross said. “Look who I ran into. Come back down with us. We’re going into town.”
“Hello, Phil,” Dolores said. “Well, aren’t you glad to see me?”
He nodded. “How have you been? You’re looking fine.” She was still pretty and slender in her uniform, the blue-grey of Internal Security, Gross’ organization.
“Thanks.” She smiled. “You seem to be doing all right, too. Commander Gross tells me that you’re responsible for this project, Operation Head, as they call it. Whose head have you decided on?”
“That’s the problem.” Kramer lit a cigarette. “This ship is to be equipped with a human brain instead of the Johnson system. We’ve constructed special draining baths for the brain, electronic relays to catch the impulses and magnify them, a continual feeding duct that supplies the living cells with everything they need. But—”
“But we still haven’t got the brain itself,” Gross finished. They began to walk back toward the car. “If we can get that we’ll be ready for the tests.”
“Will the brain remain alive?” Dolores asked. “Is it actually going to live as part of the ship?”
“It will be alive, but not conscious. Very little life is actually conscious. Animals, trees, insects are quick in their responses, but they aren’t conscious. In this process of ours the individual personality, the ego, will cease. We only need the response ability, nothing more.”
Dolores shuddered. “How terrible!”
“In time of war everything must be tried,” Kramer said absently. “If one life sacrificed will end the war it’s worth it. This ship might get through. A couple more like it and there wouldn’t be any more war.”
They got into the car. As they drove down the road, Gross said, “Have you thought of anyone yet?”
Kramer shook his head. “That’s out of my line.”
“What do you mean?”
“I’m an engineer. It’s not in my department.”
“But all this was your idea.”
“My work ends there.”
Gross was staring at him oddly. Kramer shifted uneasily.
“Then who is supposed to do it?” Gross said. “I can have my organization prepare examinations of various kinds, to determine fitness, that kind of thing—”
“Listen, Phil,” Dolores said suddenly.
“What?”
She turned toward him. “I have an idea. Do you remember that professor we had in college. Michael Thomas?”
Kramer nodded.
“I wonder if he’s still alive.” Dolores frowned. “If he is he must be awfully old.”
“Why, Dolores?” Gross asked.
“Perhaps an old person who didn’t have much time left, but whose mind was still clear and sharp—”
“Professor Thomas.” Kramer rubbed his jaw. “He certainly was a wise old duck. But could he still be alive? He must have been seventy, then.”
“We could find that out,” Gross said. “I could make a routine check.”
“What
