He didn't tell her. He said, "I thought of Herkimer this afternoon. When Trevor was talking with me. I hit him this morning and I would hit him tomorrow morning if he said the same thing to me. It's something in the human blood, Eva. We fought our way up. With fist ax and club and gun and atom bomb and…"
"Shut up," cried Eva. "Keep still, can't you?"
He looked up at her in astonishment.
"Human, you say," she said. "And what is Herkimer if he isn't human? He is a human, made by humans. A robot can make another robot and they're still robots aren't they? A human makes another human and both of them are humans."
Sutton mumbled, confused. "Trevor is afraid the androids will take over. That there will be no more humans. No more original, biological humans…"
"Ash," she said, "you are bothering yourself over something that a thousand generations from now will not have been solved. What's the use of it?"
He shook his head. "I guess there is no use. It keeps stirring around in my head. There's no rest for me. Once it was so clear-cut and simple. I would write a book and the galaxy would read it and accept it and everything would be just fine."
"It still can be that way," she said. "After a while, after a long while. But to do it we have to stop Trevor. He is blinded by the same tangled semantics that blind you."
"Herkimer said one weapon would do it," Sutton said. "One weapon would be the balance that was needed. Eva, the androids have gone a long way in their research, haven't they? Chemical, I mean. The study of the human body. They would have to, to do what they have done."
She nodded. "A long way, Ash."
