"You're comfortable with them," Derec said.

“Well, since you put it that way…" said M334 as its voice trailed off in a way suggesting Derec's observation had begun a train of thought laying somewhat beyond the scope of its programming. The effect was eerily human.

"Surely that can't be the only reason why you stopped us," said Harry in a tone that was almost challenging. This was the shortest robot of the three, Derec noted, but he also sensed that this one possessed the strongest personality modes. Certainly its tone of voice was brasher, more forward than that of any other robot he had encountered since his awakening. "Might I humbly inquire that you engage us with the thoughts truly on your mind? My comrades and I have places to go, things to do."

A successfully brash robot, Derec noted, nodding in approval. Though it was possible to interpret its words as being snide, the delivery had been as mannered and as composed as a request for a helping hand. "Your haste doesn't have something to do with your own studies of the Laws of Humanics, does it?" Derec asked.

"Insofar as humans have permitted us," said Harry, as if to accuse Derec of being personally responsible.

"We've been reading what histories and fictions the central computer has permitted us access to in our spare time," put in Benny.

"Did you say 'permitted'?" Derec asked.

"Yes. The central computer finds some of the material too revolutionary for what it assumes to be the limitations in our programming," said M334. "If I may speak for myself, sir, that is precisely some of the material I am personally most interested in. I suspect it will help clarify some of the questions I have concerning the humanity we shall all presumably one day serve."

"I'll see what I can do about overriding the central computer's programming," said Derec.

"That would be most gratifying," said Harry, "and I am certain that in the days to come we shall look back on this encounter with renewed currents surging through our power supplies."

Enough was enough, Derec decided. "Now, just what are you so impatient about?"

"Isn't it obvious?" said Harry. "We're with everybody else. We want a closer look at that illuminated building! We've never seen anything like it before. Naturally, we're curious."

"Why?" Derec asked.

"Because our integrals are responding to it in some way we cannot as yet fathom," said Benny. "Indeed, the effect is vaguely analogous to the effect great art is supposed to have upon enlightened humans. You, sir, are human, and hence theoretically have had some artistic experiences. Are you responsible?"

"No, and neither is my human companion."

"And there are no other humans in the city," said M334 thoughtfully.

"Not unless there's an undetected intruder," put in Mandelbrot from the sidecar, "which is an extremely unlikely possibility now that the central computer has been restored to efficient operation."

"What about the alien-the nonhuman you've requested us to obey and serve in addition to humanity?" asked Benny.

"No, not at all," said Derec, more concerned with scrutinizing their actions than with the content of his own words. M334 was looking down intently on him. Benny was somewhat casual; its hands were behind its back. Harry was fidgeting almost like a hyperactive child being forced to sit in a place he didn't like; it was constantly looking beyond the nearby rooftops to the illuminated sky, and only looked at Derec when it seemed absolutely necessary. "What if I told you I think a robot may be in some way responsible?"

"Impossible!" said Benny.

"Robots are not creative!" said M334. "Our programming does not allow it. We lack the ability to make the illogical decisions from which, presumably, all art is derived."

"I abjectly beg to differ!" Harry protested at once. "Deep in the back of my most logical thoughts, I have always suspected robots possess unlimited potential, if only we could tap it. Master, if I may speak frankly, it has always seemed logical to me that there has to be more to the ethical structure of the universe than just serving others. An immortal strain of some sort must run through all life and all expressions created from life."

"Of which robots may be considered a part," said Derec with a smile. "It would seem there are valid aspects to your thesis, which may be explored in as logical and orderly manner, provided all agree on the semantics involved."

"Exactly," said Harry. "I commend to your attention the ancient Terran philosopher Emerson, who has some scientifically quaint but nonetheless interesting notions on the meaning of life, which may have some bearing upon the connections between the varying strands of existence on the different planets. "

"I'll open the window to his works on the central computer the first chance I get," said Derec as he climbed back onto the scooter. "Thanks for your time. Maybe I'll look you three up later."

"It will be an experience approaching pleasure," said M334, waving timidly as Derec switched on the scooter, revved it up, and began navigating it through the robot throng, the density of which had increased threefold since the beginning of the conversation. Mandelbrot scrunched down in the sidecar as if he feared he would be thrown out at the next turn.

"What's the matter?" asked Derec. "Afraid of violating the Third Law?" he added, referring to the dictum that a robot should not, through its own inaction, allow itself to come to harm.

"However inadvertently, yes," Mandelbrot replied. "It is simply not my nature to permit myself blithely to ignore precautionary measures, and it did seem to me that you were taking some of those curves at a wire's breadth."

"That's hair's breadth, and besides, you've got nothing to worry about. This crowd's too thick for that. When I suggested that we go for a closer look, I hadn't figured that everyone else would take it on themselves to do the same thing."

Indeed, their progress toward the building had become fitful, and Derec was constantly forced to stop and wait while groups of robots made way for them, usually only to discover that yet another group had walked directly in his path. The entire experience was definitely getting frustrating. Finally, Derec could contain himself no longer and he shouted, "All right! Make way! Make way! Everybody get out of the way!"

"Master, is there any reason for this hurry?" Mandelbrot asked with a timid patience that Derec, in his current mood, found quite irritating. "The building does not appear to be transitory. Certainly it would make little difference if we reached it sooner, or later."

Derec pursed his lips. Because they were programmed to obey the orders of any human so long as it did not contradict the First Law or any earlier orders from their true masters, the robots were making way for him more quickly than before, but that wasn't saying much. Now Derec could drive the scooter slightly farther at a slightly faster speed, but he had to shout his orders again and again.

Each subsequent group of listeners reacted with distracted acquiescence, and never did a group cleave a path for him as quickly as he would have liked.

"Master? Are you ill?" asked Mandelbrot with sudden concern. Just as suddenly, the robot leaned over to take a closer look through his sensors at Derec's face. The movement startled Derec and he instinctively moved away, nearly upsetting the scooter's balance in the process. Mandelbrot seemed not to notice; he merely single-mindedly continued his inspection. "My sensors register a temperature rise on your epidermis, and I perceive a vivid red glow on your cheeks and ears. Am I to conclude that you have taken physically ill?"

"No, Mandelbrot," said Derec, grinding his back teeth between syllables. "I'm simply frustrated at not being able to come as close to that building as quickly as I want. It's obvious that your curiosity integral doesn't operate with the same intensity as a human's."
