The Caves of Steel (Robot #1) Page 47
Author: Isaac Asimov

As he spoke, he took out a flat, black object which expanded into a small book-viewer. He inserted a well-worn spool into the receptacle. He then took out a stop watch and a series of white, plastic slivers that fitted together to form something that looked like a slide rule with three independent movable scales. The notations upon it struck no chord of familiarity to Baley.

Dr. Gerrigel tapped his book-viewer and smiled a little, as though the prospect of a bit of field work cheered him.

He said, "It's my Handbook of Robotics. I never go anywhere without it. It's part of my clothes." He giggled self-consciously.

He put the eyepiece of the viewer to his eyes and his finger dealt delicately with the controls. The viewer whirred and stopped, whirred and stopped.

"Built-in index," the roboticist said, proudly, his voice a little muffled because of the way in which the viewer covered his mouth. "I constructed it myself. It saves a great deal of time. But then, that's not the point now, is it? Let's see. Umm, won't you move your chair near me, Daneel."

R. Daneel did so. During the roboticist's preparations, he had watched closely and unemotionally.

Baley shifted his blaster.

What followed confused and disappointed him. Dr. Gerrigel proceeded to ask questions and perform actions that seemed without meaning, punctuated by references to his triple slide rule and occasionally to the viewer.

At one time, he asked, "If I have two cousins, five years apart in age, and the younger is a girl, what sex is the older?"

Daneel answered (inevitably, Baley thought), "It is impossible to say on the information given."

To which Dr. Gerrigel's only response, aside from a glance at his stop watch, was to extend his right hand as far as he could sideways and to say, "Would you touch the tip of my middle finger with the tip of the third finger of your left hand?"

Daneel did that promptly and easily.

In fifteen minutes, not more, Dr. Gerrigel was finished. He used his slide rule for a last silent calculation, then disassembled it with a series of snaps. He put away his stop watch, withdrew the Handbook from the viewer, and collapsed the latter.

"Is that all?" said Baley, frowning.

"That's all."

"But it's ridiculous. You've asked nothing that pertains to the First Law."

"Oh, my dear Mr. Baley, when a doctor hits your knee with a little rubber mallet and it jerks, don't you accept the fact that it gives information concerning the presence or absence of some degenerative nerve disease? When he looks closely at your eyes and considers the reaction of your iris to light, are you surprised that he can tell you something concerning your possible addiction to the use of certain alkaloids?"

Baley said, "Well, then? What's your decision?"

"Daneel is fully equipped with the First Law!" The roboticist jerked his head in a sharp affirmative.

"You can't be right," said Baley huskily.

Baley would not have thought that Dr. Gerrigel could stiffen into a rigidity that was greater than his usual position. He did so, however, visibly. The man's eyes grew narrow and hard.

"Are you teaching me my job?"

"I don't mean you're incompetent," said Baley. He put out a large, pleading hand. "But couldn't you be mistaken? You've said yourself nobody knows anything about the theory of non-Asenion robots. A blind man could read by using Braille or a sound-scriber. Suppose you didn't know that Braille or sound-scribing existed. Couldn't you, in all honesty, say that a man had eyes because he knew the contents of a certain book-film, and be mistaken?"

"Yes," the roboticist grew genial again, "I see your point. But still a blind man could not read by use of his eyes and it is that which I was testing, if I may continue the analogy. Take my word for it, regardless of what a non-Asenion robot could or could not do, it is certain that R. Daneel is equipped with First Law."

"Couldn't he have falsified his answers?" Baley was floundering, and knew it.

"Of course not. That is the difference between a robot and a man. A human brain, or any mammalian brain, cannot be completely analyzed by any mathematical discipline now known. No response can therefore be counted upon as a certainty. The robot brain is completely analyzable, or it could not be constructed. We know exactly what the responses to given stimuli must be. No robot can truly falsify answers. The thing you call falsification just doesn't exist in the robot's mental horizon."

"Then let's get down to cases. R. Daneel did point a blaster at a crowd of human beings. I saw that. I was there. Granted that he didn't shoot, wouldn't the First Law still have forced him into a kind of neurosis? It didn't, you know. He was perfectly normal afterward."

The roboticist put a hesitant hand to his chin. "That is anomalous."

"Not at all," said R. Daneel, suddenly. "Partner Elijah, would you look at the blaster that you took from me?"

Baley looked down upon the blaster he held cradled in his left hand.

"Break open the charge chamber," urged R. Daneel. "Inspect it." Baley weighed his chances, then slowly put his own blaster on the table beside him. With a quick movement, he opened the robot's blaster.

"It's empty," he said, blankly.

"There is no charge in it," agreed R. Daneel. "If you will look closer, you will see that there has never been a charge in it. The blaster has no ignition bud and cannot be used."

Baley said, "You held an uncharged blaster on the crowd?"

"I had to have a blaster or fail in my role as plain-clothes man," said R. Daneel. "Yet to carry a charged and usable blaster might have made it possible for me to hurt a human being by accident, a thing which is, of course, unthinkable. I would have explained this at the time, but you were angry and would not listen."
