Harriman smiled. "Two heads are better than one, in other words, eh, George?"
"If by that, Mr. Harriman, you mean two individuals with one head apiece, yes."
"Right. Is there anything else you want?"
"Yes. Something more than films. I have viewed much concerning human beings and their world. I have seen human beings here at U. S. Robots and can check my interpretation of what I have viewed against direct sensory impressions. Not so concerning the physical world. I have never seen it and my viewing is quite enough to tell me that my surroundings here are by no means representative of it. I would like to see it."
"The physical world?" Harriman seemed stunned at the enormity of the thought for a moment. "Surely you don't suggest I take you outside the grounds of U. S. Robots?"
"Yes, that is my suggestion."
"That's illegal at any time. In the climate of opinion today, it would be fatal."
"If we are detected, yes. I do not suggest you take me to a city or even to a dwelling place of human beings. I would like to see some open region, without human beings."
"That, too, is illegal."
"If we are caught. Need we be?"
Harriman said, "How essential is this, George?"
"I cannot tell, but it seems to me it would be useful."
"Do you have something in mind?"
George Ten seemed to hesitate. "I cannot tell. It seems to me that I might have something in mind if certain areas of uncertainty were reduced."
"Well, let me think about it. And meanwhile, I'll check out George Nine and arrange to have you occupy a single cubicle. That at least can be done without trouble."
3a.
George Ten sat alone.
He accepted statements tentatively, put them together, and drew a conclusion; over and over again; and from conclusions built other statements which he accepted and tested and found a contradiction and rejected; or not, and tentatively accepted further.
At none of the conclusions he reached did he feel wonder, surprise, satisfaction; merely a note of plus or minus.

Harriman's tension was not noticeably decreased even after they had made a silent downward landing on Robertson's estate.
Robertson had countersigned the order making the dyna-foil available, and the silent aircraft, moving as easily vertically as horizontally, had been large enough to carry the weight of Harriman, George Ten, and, of course, the pilot.
(The dyna-foil itself was one of the consequences of the Machine-catalyzed invention of the proton micro-pile which supplied pollution-free energy in small doses. Nothing had been done since of equal importance to man's comfort-Harriman's lips tightened at the thought-and yet it had not earned gratitude for U. S. Robots.)
The air flight between the grounds of U. S. Robots and the Robertson estate had been the tricky part. Had they been stopped then, the presence of a robot aboard would have meant a great set of complications. It would be the same on the way back. The estate itself, it might be argued-it would be argued-was part of the property of U. S. Robots and on that property, robots, properly supervised, might remain.
The pilot looked back and his eyes rested with gingerly briefness on George Ten. "You want to get out at all, Mr. Harriman?"
"Yes."
"It, too?"
"Oh, yes." Then, just a bit sardonically, "I won't leave you alone with him."
George Ten descended first and Harriman followed. They had come down on the foil-port and not too far off was the garden. It was quite a showplace and Harriman suspected that Robertson used juvenile hormone to control insect life without regard to environmental formulas.
"Come, George," said Harriman. "Let me show you." Together they walked toward the garden.
George said, "It is a little as I have imaged it. My eyes are not properly designed to detect wavelength differences, so I may not recognize different objects by that alone."
"I trust you are not distressed at being color-blind. We needed too many positronic paths for your sense of judgment and were unable to spare any for sense of color. In the future-if there is a future-"
"I understand, Mr. Harriman. Enough differences remain to show me that there are here many different forms of plant life."
"Undoubtedly. Dozens."
"And each coequal with man, biologically."
"Each is a separate species, yes. There are millions of species of living creatures."
"Of which the human being forms but one."
"By far the most important to human beings, however."
"And to me, Mr. Harriman. But I speak in the biological sense."
"I understand."
"Life, then, viewed through all its forms, is incredibly complex."
"Yes, George, that's the crux of the problem. What man does for his own desires and comforts affects the complex total-of-life, the ecology, and his short-term gains can bring long-term disadvantages. The Machines taught us to set up a human society which would minimize that, but the near-disaster of the early Twenty-first Century has left mankind suspicious of innovations. That, added to its special fear of robots-"
"I understand, Mr. Harriman...That is an example of animal life, I feel certain."
"That is a squirrel; one of many species of squirrels."
The tail of the squirrel flirted as it passed to the other side of the tree
"And this," said George, his arm moving with flashing speed, "is a tiny thing indeed." He held it between his fingers and peered at it.
"It is an insect, some sort of beetle. There are thousands of species of beetles."
