of loud noises, too, but are you afraid of them?"
"Not within reason," said Baley.
"I'm willing to bet that Earth people couldn't sleep if things were really quiet. Skies above, there isn't an instinct around that can't give way to a good, persistent education. Not in human beings, where instincts are weak anyway. In fact, if you go about it right, education gets easier with each generation. It's a matter of evolution."
Baley said, "How is that?"
"Don't you see? Each individual repeats his own evolutionary history as he develops. Those fetuses back there have gills and a tail for a time. Can't skip those steps. The youngster has to go through the social-animal stage in the same way. But just as a fetus can get through in one month a stage that evolution took a hundred million years to get through, so our children can hurry through the social animal stage. Dr. Delmarre was of the opinion that with the generations, we'd get through that stage faster and faster."
"Is that so?"
"In three thousand years, he estimated, at the present rate of progress, we'd have children who'd take to viewing at once. The boss had other notions, too. He was interested in improving robots to the point of making them capable of disciplining children without becoming mentally unstable. Why not? Discipline today for a better life tomorrow is a true expression of First Law if robots could only be made to see it."
"Have such robots been developed yet?"
Klorissa shook her head. "I'm afraid not. Dr. Delmarre and Leebig had been working hard on some experimental models."
"Did Dr. Delmarre have some of the models sent out to his estate? Was he a good enough roboticist to conduct tests himself?"
"Oh yes. He tested robots frequently."
"Do you know that he had a robot with him when he was murdered?"
"I've been told so."
"Do you know what kind of a model it was?"
"You'll have to ask Leebig. As I told you, he's the roboticist who worked with Dr. Delmarre."
"You know nothing about it?"
"Not a thing."
"If you think of anything, let me know."
"I will. And don't think new robot models are all that Dr. Delmarre was interested in. Dr. Delmarre used to say the time would come when unfertilized ova would be stored in banks at liquid-air temperatures and utilized for artificial insemination. In that way, eugenic principles could be truly applied and we could get rid of the last vestige of any need for seeing. I'm not sure that I quite go along with him so far, but he was a man of advanced notions; a very good Solarian."
She added quickly, "Do you want to go outside? The five through eight group are encouraged to take part in outdoor play and you could see them in action."
Baley said cautiously, "I'll try that. I may have to come back inside on rather short notice."
"Oh yes, I forgot. Maybe you'd rather not go out at all?"
"No." Baley forced a smile. "I'm trying to grow accustomed to the outdoors."
The wind was hard to bear. It made breathing difficult. It wasn't cold, in a direct physical sense, but the feel of it, the feel of his clothes moving against his body, gave Baley a kind of chill.
His teeth chattered when he tried to talk and he had to force his words out in little bits. It hurt his eyes to look so far at a horizon so hazy green and blue and there was only limited relief when he looked at the pathway immediately before his toes. Above all, he avoided looking up at the empty blue, empty, that is, but for the piled-up white of occasional clouds and the glare of the naked sun.
And yet he could fight off the urge to run, to return to enclosure.
He passed a tree, following Klorissa by some ten paces, and he reached out a cautious hand to touch it. It was rough and hard to the touch. Frondy leaves moved and rustled overhead, but he did not raise his eyes to look at them. A living tree!
Klorissa called out. "How do you feel?"
"All right."
"You can see a group of youngsters from here," she said. "They're involved in some kind of game. The robots organize the games and see to it that the little animals don't kick each other's eyes out. With personal presence you can do just that, you know."
Baley raised his eyes slowly, running his glance along the cement of the pathway out to the grass and down the slope, farther and farther
