The robot at Ariel’s side interrupted. “I do not think it would be wise to revive him. He is dangerous.”
“I agree with Mandelbrot,” the wolflike learning machine beside him said. “Much as we regret the loss of our companion, his experiences have damaged him beyond repair. It would be best to let his pathways randomize.”
Janet looked at the old, Ferrier-model robot. Mandelbrot? She’d thought she’d heard that name shouted earlier. Could this be the one? It seemed impossible, but he did have a dianite arm…
“Maybe so,” Derec said, “but not until I get a recording of them first. Now where is his body?”
“In the lab next door,” said Mandelbrot.
“Great.” Derec turned to go, but stopped and looked at Janet again. “I, uh, could probably use your help if you want to come along.”
She felt the tension in the room ease slightly. She looked from him to Ariel to Wendell in the operating room, wondering if she should go. She didn’t want to leave Wendell, but the medical robot had given him a general anesthetic in order to stop him from thinking about his injury, so it really made no difference to him. Going with Derec, on the other hand, might matter to him. A little stunned that she might actually care about what either of them felt, or that she might feel something herself, she said, “I don’t think I’m doing anyone any good here, so sure, why not?”
“I’ll stay here,” Ariel said.
Janet couldn’t tell if she meant that angrily or helpfully. She didn’t suppose it mattered much; the same response would work for either case. “Thank you,” she said, and let Derec lead her from the room.
Basalom followed along, as did the two learning machines. They found the remains of the third, Lucius, resting like a battered starfish on the floor just inside the door to the lab. It looked as if part of the battle had gone on in there as well, but Derec, stepping over Lucius’s body, said, “1 guess I forgot to clean up. Central, fix these exam tables, please. And go ahead and reabsorb the loose cells on the floor. All but what belongs to Lucius, of course.”
The sandy grit surrounding the pedestals on the floor sank into the surface, and the pedestals simultaneously grew taller and spread out at the top to form three separate exam tables. Janet nodded to Basalom and said, “Go ahead and put him on one. Then go out and scrape up what you can from outside.”
Basalom lifted Lucius easily with his one remaining hand and deposited him on the middle table, then left the room. The Ariel-shaped learning machine went with him. Janet was itching to speak with one of the learning machines, but she supposed there would be time for that later. She was itching to speak with Derec as well, but he was already absorbed in the task of hooking up a variable power supply and a brain activity monitor to Lucius.
She supposed she could be helping with that, at least. She walked over to stand across the exam table from him and said, “Plus and minus five volts will do for his memories. If you hold it at that, he shouldn’t wake up, and even if he does, he’ll still be immobilized because the body cells take twenty volts before they can move.”
Derec nodded. The stray hair at his temple waved like a tree limb in a breeze. “Good,” he said. “Any special place I should attach the leads? The few times I’ve worked on these guys, I’ve just stuck stuff anywhere and let the cells sort it out, but I wasn’t sure if that was the best way. “
Janet couldn’t resist reaching out and brushing his hair down. He looked surprised at first, then smiled when he realized what she was doing.
“Anywhere is fine,” she said. “When I designed the cells, I gave them enough hard wiring to figure out what to do with all the various types of input they were likely to get.”
“Good.”
She watched Derec clip the power supply’s three leads to the ends of three different arms, then turn up the voltage to five. He then took the brain monitor’s headphone-shaped sensor and moved it over the robot’s unconventional body, searching for its positronic brain. The monitor began to beep when he reached the base of one of the arms, and he wedged it in place with one pickup underneath and one on top.
The monitor flickered with sharp-edged waveforms, hundreds of them joining to fill the screen until it was a jumble of multicolored lines. “Looks like we caught him in time,” Derec said. “There seems to be quite a bit of mental activity.” He reached up and switched in a filter, and the jumble diminished to a manageable half-dozen or so waveforms. They weren’t actual voltage traces, but rather representations of activity in the various levels of the brain, useful for visualizing certain types of thoughts.
Janet frowned. “ Are those supposed to be the Three Laws?”
“That’s right.”
The pattern was still recognizable as the one built into every positronic brain at the time of manufacture-but just barely. Each of the laws showed in a separate hue of green, but overlaying them all were two companion waves, a deep violet one that split and rejoined much as the Three Laws did, and a lighter blue one weaving in and out around the laws and linking up with other signals from all over the screen. The effect looked as if the violet and blue waves were purposefully entangling the laws, preventing them from altering their potential beyond carefully delineated levels. Janet suspected that was just what they were doing. Visual analogy didn’t always work in describing a robot’s inner workings, but in this case it looked pretty straightforward.
“I’d say that explains a lot,” she said.
Derec flipped to another band, following the two waves as they wove from the Three Laws through the self-awareness section and into the duty queue. “Looks like he’s built a pretty heavy web of rationalization around just about all the pre-defined areas of thought,” he said. “Normal diagnostic procedure would be to wake him up and ask him what all that means, but I don’t think we want to do that just yet. Adam, you know how he thinks; can you make sense of it?”
The one remaining learning machine stepped over to Derec’s side. Adam? Had he known the significance of that name when he chose it, or had it been given to him? Janet supposed the other one would be Eve, then. And this one, the renegade, was Lucius. Why hadn’t he gone for the obvious and called himself Lucifer? She itched to ask them. She had to talk with them soon.
In answer to Derec’s question, Adam said, “The violet potential schematic corresponds to the Laws of Humanics. The blue one is the Zeroth Law of Robotics.”
“Beg your pardon?” Janet asked. “Laws of Humanics? Zeroth Law? What are you talking about?”
Her learning machine looked over at her and said, “We have attempted to develop a set of laws governing human behavior, laws similar to the ones that govern our own. They are, of course, purely descriptive rather than compulsory, but we felt that understanding them might give us an understanding of human behavior which we otherwise lacked. As for the Zeroth Law, we felt that the Three Laws were insufficient in defining our obligations toward the human race in general, so we attempted to define that obligation ourselves.” I
Janet was careful not to express the joy she felt, for fear of influencing the robot somehow, but inside she was ecstatic. This was perfect! Her experiment was working out after all. Her learning machines had begun to generalize from their experiences. “ And what did you come up with?” she asked.
“Bear in mind that these laws describe potential conditions within a positronic brain, so words are inadequate to describe them perfectly; however, they can be expressed approximately as follows. The First Law of Humanics: All beings will do that which pleases them most. The Second Law of Humanics: A sentient being may not harm a friend, or through inaction allow a friend to come to harm. The Third Law of Humanics: A sentient being will do what a friend asks, but a friend may not ask unreasonable things.” He paused, perhaps giving Janet time to assimilate the new laws’ meanings.
