Whatever had hit them, it had taken only a thin slice... this time.
Bickel raised his hand to the transmitter pulse switch, depressed it. The room around him filled with the hum of the instrument as it built up the energy to hurl its multiburst of information back across space. The "snap-click" of the transmission interlock with its dim smell of ozone came almost as an anticlimax.
"They won't make any more of this than we do," Timberlake said.
"UMB has some of the top men in particle physics," Bickel said. "Maybe they can solve it."
"A neutrino phenomenon?" Timberlake asked. "Nuts! They'll claim we misread the evidence."
"Time for my watch," Flattery said. "Prue?"
Flattery's words made her aware in a sudden rush of acceptance how tired she was. Her back ached and the muscles of her forearms trembled. She could remember only once before having been this tired - after almost five hours of surgery.
In many ways, she was making too-heavy demands on her flesh - with long watches, work in the shop, and the tests using her own body as a guinea pig. But the adrenochrome-THC was proving difficult. It wouldn't cross the blood-brain barrier into active contact with neural tissue... unless she dared use a near-fatal dosage. She hadn't yet dared, although the prize appeared dazzling.
If she could only inhibit the lower structures of the brain and release the higher structures to full activity, she could hand Bickel the sequential steps to duplicate as electronic functions.
"Shift the board on the count," she said.
As they shifted the big board, Flattery scanned the instruments preparing to fit himself into the mood of the ship. And the Tin Egg does have her moods.
Sometimes, he felt as though the ship carried ghosts within it - of the sixteen clones killed by accident during the construction on the Moon, of umbilicus crew members killed by the ship's programmed savagery - or perhaps of the OMCs sacrificed on this altar. An altar to human hubris.... Those previous tests - all of the dead crews, colonists... and the OMCs. All ghosts riding with us.
Did those bodiless brains have souls? Flattery wondered. For that matter - if we breathe consciousness into this machinery, will our creation have a soul?
"Have the automatics finished sealing the break?" Bickel asked.
"All sealed," Flattery said. And he asked himself: When will the rogue consciousness hit us again?
"What was in Stores Four?" Prudence asked. "What'd we lose?"
"Food concentrates," Bickel answered. "First thing I checked." His tone said, "You had the watch; you should've checked that."
"Raj, do you want us to start sharing watch and watch?" Timberlake asked. "After I've had some rest..."
"After you've had some rest, you can help me in the shop," Bickel said.
Flattery glanced at Bickel, then at Timberlake, wondering how the life-systems engineer would take that rebuke. Timberlake had his eyes closed. His fatigue was obvious in the pale, flaccid look of his face. He appeared almost asleep... except for tight, shallow breathing.
"You want to go right ahead, eh?" Prudence asked. "You don't think we should wait for Hempstead's trained seals to chew this over?"
"Whatever hit us came from outside," Bickel said. "That's another problem."
"John's right," Timberlake rasped. He cleared his throat, unsnapped his action couch, sat up. "I'm bushed."
"We've just decided," Prudence said, "just like that..." she snapped her fingers, "- that you can go on stirring around in the computer like a wild man?"
"For Christ's sake!" Bickel said. "Haven't any of you realized yet we were supposed to use the computer as the basic element of attack?"
Bickel stared around at them - Flattery busy on the board, Timberlake half asleep sitting up at his couch, Prudence glaring at him from her couch.
"That's no ordinary computer. It has elements we don't even suspect. It was hooked up with an Organic Mental Core for almost six years during the construction and programming of the ship. It has buffers and leads and cross-ties that its own designers may not even know about!"
"Are you suggesting it's already conscious?" Prudence asked.
"No, I'm only suggesting that we've come a long way using that computer and our Ox frontal-lobe simulator. We've come further than the UMB project did in twenty years! And we should go on with this. We're cutting a straight line through -"
"There are no straight lines in nature," Flattery said.
Bickel sighed. What now? he wondered. "If you've got something to say, spit it out."
"Consciousness is a type of behavior," Flattery said.
"Agreed."
"But the roots of our behavior are buried so far away in the past we can't get at them directly."
"Emotion again, eh?" Bickel demanded.
"No," Flattery said.
"Instinct," Prudence said.
Flattery nodded. "The kind of genetic imprint that tells a chicken how to crack out of its shell."
"Emotions or instinct, what's the difference?" Bickel asked. "Emotions are produced by instinct. Are you, still saying we can't bring the Ox to consciousness unless it has instincts-cum-emotions?"
"You know what I'm saying," Flattery said.
"It has to love us," Bickel said. He chewed at his upper lip, caught again by the beautiful simplicity of the suggestion. Flattery was right, of course. Here was a loose rein that could satisfy the fail-safe requirements. It controlled without galling.
"It has to have an autonomic system of emotional reactions," Flattery said. "The system has to respond with a set of physical effects of which the Ox is... aware."
Emotion, Bickel thought. The characteristic that gives us our sense of person, the thing that summates personal judgments. A process in capsule form that can occur out
of sequence.
Here was a break with all machine concepts of time - emotion as process, an audacious way of looking at time.
"There's nothing of ourselves about which we can be objective," Bickel said, "except our own physical responses. Remember? It's what Dr. Ellers was always saying."
Flattery thought back to Ellers, UMB's chief of psych. "Bickel is 'purpose,' the force that will give direction to your search," Ellers had said. "You have substitutes, of course. Accidents do happen. But you've nothing honed as fine as Bickel. He's a creative discoverer."
A "creative discoverer" - the failures of all who went before him... all of those clone-brothers, all was preparation for this assault on the problem. If we succeed we survive, and if we fail...
And Bickel was thinking: Emotion. How do we symbolize it and program for it? What does the body do? We're inside, in direct contact with whatever the body's doing. That's the only thing we can really be objective about. What does the body...
"It has to have a completely interfunctioning body," Bickel said, seeing the whole problem and answer as an abrupt revelation. "It has to have a body that's gone through trauma and crises." He stared at Flattery. "Guilt, too, Raj. It has to have guilt."
"Guilt?" Flattery asked, and wondered why the suggestion made him feel angry and half fearful. He started to object, grew conscious of a rhythmic rasping. He thought at first it was a malfunctioning alarm, realized then it was Timberlake. The life-systems engineer had reclasped himself in his action couch cocoon. He was asleep - snoring.
"Guilt," Bickel said, holding his attention on Flattery.
"How?" Prudence asked.
"In program engineering terms," Bickel said, "we must install trapping functions, inner alarm systems - monitors that interrupt operations according to the functional needs of the entire system."
"Guilt's an artificial emotion; it has nothing to do with consciousness," Flattery objected.
"Fear and guilt are parent and child. You can't have guilt without fear."
