"I have done what I have done," said the gray, looking away with a bearing that, had it been human, Derec could have described as a huff. "I have harmed no robot, no human, and certainly not myself. In fact, if you would care to open your receptors and seek out empirical justification for your opinions, you will see that thus far I have only expanded the awareness of the robots gathered around. Such expansion of perspective can only be positive."
"You cannot prove that," replied the ebony at once. "You can only surmise it."
"One can reasonably assume one is doing the greatest good. True enough, some harm may come from forces one cannot have reasonably predicted, but such a rationale is in and of itself no reason to remain inactive. Inany case, the matter is settled for the moment. What is done cannot be undone."
"All robots can be ordered to forget, and they will!" said the ebony defiantly.
"What I have done is stronger than mere memory," replied the gray. "What I have done will affect the positronic functioning of every robot that has seen my building. Order them to forget-see if I care." The gray turned as if to walk away. Instead, it paused and said, "But, I submit, they will be infinitely better off if they do know why. The confusion of forgetfulness can often lead to overload-and hence to disaster. So how does your suggestion conform to the Three Laws now?"
For a long moment the ebony actually appeared crushed by the question. Then it mustered its posture, took a few steps forward, and put its hand on the chromium robot's shoulder. staring down at it as if it were looking at a crystal through an electron microscope. The ebony's eyes were so red that they seemed to be comprised of as many floating divisions of overlaid hues as did the planes of the building. "Your building is a remarkable conceptual feat," it said to the gray. "Could it be you directly copied the building from some preexisting design?"
"Forgive me, my friend," replied the gray, "but my conception simply came to me one afternoon. I responded by making it a reality. I would mention that the central computer would have overridden my instructions if I had requested anything conflicting with city programming."
"Interesting," replied the ebony, rubbing its hands together. Derec half expected sparks to fly. "Then how long can we expect this building to stand?"
"Until the central computer is given a direct order to wash it away. Only I know the code; however, I imagine it is barely possible that a sufficiently determined critic could discover it and override it. "
The ebony's eyes brightened. Derec tensed as he watched the ebony draw itself up to its full height. "This is madness! Illogic runs rampant! Your deeds have irrevocably cut the pattern of our existence!"
"Not at all," said the gray demurely. "The building was a logical result of something that had impressed my circuits the wrong way ever since the humans arrived in our city." For the first time it acknowledged the presence of Derec and Ariel, with a slight bow. "And surely, if my vision is the logical result of the complex interaction of my positronic pathways, then anything I can come up with-and any deed I can accomplish-is a meet and proper activity, especially if it helps robots better understand the behavioral complexities of humans."
"In that case," said the ebony, "You shall reprogram central to do away with the building, and then open your brain repository to share your pathway nuances with us. It should never be necessary for you to create again."
"He shall do no such thing!" exclaimed Derec. "Hear me, ebony, whoever you think you are," he added, practically poking his finger in the robot's face. "Until other humans arrive here, or until the engineer who created this city reveals his presence, this building shall remain as long as its-its creator wishes it to stand. This is a direct order and may not be countermanded by central or by anyone else! Do you understand? A direct order! And it shall apply to every robot in the city! There shall be no exceptions!"
The ebony nodded. "As you wish."
Derec could only assume that the ebony would carry out his orders to the letter. Only an order given by someone in precedence-Dr. Avery, to be precise-or a necessity dictated by the Three Laws would permit the building to be reabsorbed now.
And to emphasize that fact, lest the ebony should strive to pinpoint some logical flaw in the command, Derec ignored all other robots-especially the ebony-in favor of the gray. He turned to him and asked, "What is your designation?"
"Lucius."
"Lucius? No number?"
"Like many of my comrades, I recently decided that my former designation was no longer adequate."
"Yes, there seems to be a lot of that going around lately. All right, Lucius, I think the time has come for you and me to take a little walk."
"If that is your command," said Lucius noncommittally.
A few moments later, Derec and his three friends were escorting the robot called Lucius from the square. The vast majority of the robots had returned their attention to the building, but Derec was uncomfortably aware of two red metal eyes glaring at him, as if to bore deep into his soul.
Chapter 3. Circuit Breaker
Now that he was walking down the same streets he had ridden the scooter through earlier, Derec took advantage of the slower pace to try to deduce how much the city had changed in the interim. Complicating the deductions was the fact that his previous speed hadn't been very accommodating. He'd had only glimpses before, and he wasn't sure if he was remembering half of them correctly.
But after he'd made allowances for the flaws in his survey, he was convinced that entire buildings had been replaced by new ones in an assortment of geometric designs that, for all their variety, nonetheless possessed a cookie-cutter sameness. In some places, whole blocks had been transformed. However, the streets remained roughly consistent with previous directions, despite the addition of many twisted, almost gnarled turns.
The farther he went from Lucius's building, the more unexpected diversions there were, in the forms of metalworks, fenced run-off canals, bridges, and power stations. Derec felt fortunate that his talents included a fairly strong sense of direction; otherwise, he would always be forced to rely on robots for navigational purposes. There was nothing wrong with that-robots had an excellent sense of direction-but he couldn't always assume a robot would be around when his survival depended on it.
But wherever he was, he could always see the distant shards of light shining from Lucius's building. They stabbed up from the surrounding darkness like ethereal swords rising up from a pit, swords that cut deep into the cloud banks high in the sky. The clouds twisted and rolled, covering new sections of sky, as if the light were stirring an inner fire.
The group with Derec-Ariel, Mandelbrot, Wolruf, and Lucius-walked in silence, as they had been doing for some time. Derec suspected that all of them, even Mandelbrot, required a few minutes lost in their own thoughts to digest what they had seen tonight.
Derec wished it weren't so difficult to remember so much of his knowledge of galactic histories and customs. Not only had he lost his personal history, but he had forgotten the methods he used to recall things. He'd lost his entire mental filing system, and had to be immersed in doing something, such as fixing a robot, before it came back to him.
He did not like this state of affairs because he did not like to think that he and Ariel-both of whom were mentally handicapped at the moment-were the only ones who had ever encountered robots that were capable of searching, creative thought. He wondered if originality in humans was the result of logical thinking as much as transcendent inspiration.
Besides, who was to say that robots didn't possess subconscious minds of their own, minds capable of generating their own brands of inspiration, neither superior nor inferior to those of humankind but merely separate? After all, humans themselves hadn't been aware of the existence of the subconscious mind until it had been defined by primitive scientists and doctors, before the era of colonization. Had anyone ever bothered to make similar explorations into the mental depths of robots? It frightened Derec to think that he had the potentially awesome responsibility of witnessing the robots during-and possibly midwifing them through-their mental birth pains. He hardly felt qualified.
