"Games theory!" Flattery sneered. "You can't predict all the behavior of your machine." He looked back at the telltales.
What was Tim doing?
"That's just it!" Bickel said. "If the machine's going to be conscious, we can't predict all of its behavior... by the very nature of consciousness, by definition. Consciousness is a game where the permissible moves aren't arbitrarily established in advance. The sole object's to win."
Anything goes? Flattery wondered. He focused suddenly on Bickel, recognizing the essentially blasphemous nature of such a concept. There had to be rules!
"The machine gets part of its personality from its creator, part from its opponents," Bickel said.
Something from God, something from the Devil, Flattery thought. There had to be essential error in this path... somewhere. Bickel was behaving far outside the predictions. Their "organ of analysis" was acting illogically. He was not making the best possible move each time.
"You'll introduce error factors and loss increment into the entire computer," Prudence cautioned. "That's not only illogical, it's -" She broke off, studied her board, made a pressure-balance correction in the atmospheric recirculation system, and waited to see if the automatics could hold the new setting.
"You have to make the best possible move at all times," Flattery said. "Your suggestion does not appear to -"
"There you've hit it," Bickel agreed. "Best possible move. Sometimes your best possible move is to make a dangerously poor move that changes the entire theoretical structure of the game. You change the game."
"What about all those lives down in the hyb tanks?" Prudence, asked. "Do they have any choice in this... game?"
"They already made their choice."
"And while they're helpless, you change the rules," Flattery said.
"That was one of the chances they accepted when they accepted hybernation," Bickel said. "That was their choice."
Flattery abandoned the argument, pushed himself off his action couch.
"What're you going to do?" Prudence asked.
"Check on Tim."
"Where is Tim?" Bickel asked.
"Down in the hyb tanks," Flattery said, knowing Bickel could get the answer himself - once he consulted the shop's repeaters.
"Deep in the hyb tanks?" Bickel asked.
"Of course!"
"Prue!" Bickel snapped. "Try to raise him on the command circuit."
She heard the urgency in Bickel's voice, whirled to obey.
There was no response from Timberlake.
"You fools!" Bickel said.
Flattery stopped at the tube hatch, glared up at the screen.
"Who let him go down into the deep tanks?" Bickel demanded. "You blind idiots! Don't you know what he's likely to find down there?"
"What do you mean?"
"This whole damn ship's nothing but a simulation device," Bickel said. "There'll be nothing down there except a few crew replacements. Those tanks have to be empty!"
He's wrong! Flattery thought. Or is he?
The thought staggered Flattery. He saw immediately how that might pull the props out from under Timberlake...an tuned as fine as the rest of them for a specific function.
"He'd still have the crew systems," Prudence said. She stared across the room at Flattery, feeling the loneliness. The Tin Egg with its programmed peril might contain only a few isolated humans launched into nowhere.
They wouldn't, Flattery thought. But if they'd prepare me to cheat the rest of the crew... His feet felt rooted to the deck. He swallowed in a dry throat. But it's impossible! They promised me when I discovered the actual Tau Ceti records - if we succeeded we could just send back the message capsule and continue as...
"Raj, are you sick?" Prudence asked. She studied him, seeing the lost, sunken look in his eyes.
"The Tau Ceti planets are uninhabitable, yes," Hempstead had admitted when confronted with the evidence. "No Eden. But the universe is known to contain billions of inhabitable planets. You realize you can't come back here, of course. The danger to your hosts."
"The biopsy donors were all criminals," Flattery had said, springing his other suspicion.
"Brilliant people, but misdirected," Hempstead had protested. "That is one of the reasons you can't come back, but nothing's to stop you from going on to explore and find your own Eden."
Remembering the words, Flattery felt how hollow they sounded.
Sham and trickery all the way, he thought. But why?
CHAPTER 20
In a right-handed person, the so-called rational function operates mainly from the left hemisphere of the cerebral cortex. The 'intuitive' operation, however, lives mainly in the right hemisphere. There is strong evidence for positive feedback between the two hemispheres operating along the corpus callosum. The substance of this interchange remains largely a mystery, but there can be no doubt that it serves an important function in consciousness.
TIMBERLAKE HAD launched himself down the communications tube with desperate haste, knowing he had to move swiftly or become stalled in terror.
At the tube-distribution lock, he sealed the hatch behind him, snatched a robox-monkey from its rack, tuned the sensors to the track imprinted in the tube wall, slammed its wheels onto the guide marks, and grabbed the handhold controls. Again he encountered that terrifying reluctance to move, and stared up the tube, studying the long, infinity curve of it visible through the transparent safety locks.
I can't go back, he thought.
With a sudden wrench, he twisted the little robox tow unit's drive to full on, let it jerk him ahead along that curving track.
The wind of his passage was a dim hiss. He was like a loose piston driving down that tube. Locks opened automatically to the robox signal, closed behind him. He slowed for the protective jog through the shielding layer, twisted around through the branching outside the hyb tanks, dove back down along the flat angle that returned through the watershield, and stopped in the lock chamber to the tanks.
He racked the robox, stared at the hatch. It was a big yellow oval, its seal warning in heavy blue letters: "THIS HATCH MUST BE CLOSED AND DOGGED. BEFORE INNER HATCH WILL OPEN!"
Now that he was faced with it, Timberlake felt a calm submission to fate. He gripped the hatch dogs, broke the seal, seeing the line of frost inside as the hatch swung open. His suit generators hummed upscale, compensating for the drop in temperature as chill air spilled out of the lock.
Timberlake slipped into the lock, closed and sealed the outer hatch, turned around. A rack of heavy-duty generators hung over the inner hatch with a big warning sign above them: "EXTREME DANGER! DEEP SPACE OR L-T SUIT REQUIRED BEFORE ENTERING THE NEXT LOCK. BE SURE YOU HAVE SPARE GENERATOR IN WORKING CONDITION BEFORE OPENING THIS HATCH."
Timberlake looped the straps of a spare generator over his shoulder, gave the thing's turbine drive a short burst to check it. The generator hummed briefly. He swung the rack of them aside, broke open the next hatch, slipped through and dogged it behind him.
Now, a smaller hatch greeted him, and lettered on its face: "ADMISSION ONLY TO LIFE-SYSTEMS ENGINEERS OR MEDICAL PERSONNEL. SUIT SECURITY MUST BE MAINTAINED AT ALL TIMES BEYOND THIS POINT. DO NOT OPEN THIS HATCH UNTIL YOU HAVE ADJUSTED YOUR SUIT FOR THE EXTREME LOW OF HYBERNATION TEMPERATURES."
Timberlake coupled the auxiliary generator to his suit, checked both generators, adjusted them for temperature-security override. The remembered routine occupied his awareness, keeping his mind off the space beyond that hatch. Suit seals slithered under his gloved fingers as he secured them. He dropped the anti-fog viewplate over his faceplate, ran a check tape along the seals.
