"Colonel Mannheim mentioned that," Stanton said. "Are you implying that the Nipe thinks there are other Nipes around, running the world from secret hideouts, like the villains in a Fu Manchu novel?"
"Not quite," said Yoritomo, laughing. "The Nipe is not at all incapable of learning something new. In point of fact, he is quite good at it, as witness the fact that he has learned many Earth languages. He picked up Russian in less than eight months simply by listening and observing. Like our own race, his undoubtedly evolved a great many languages during the beginnings of its progress—when there were many tribes, separated and out of communication with each other. It would not surprise me to find that most of these languages have survived and that our distressed astronaut knows them all. A new language would not bother him in the least.
"Nor would strangely shaped intelligent beings make him unhappy. His race should be aware, by now, that such things must exist. But it is very likely that he equates true intelligence with technology, and I do not think it likely that he has ever met a race higher than the barbarian level before. Such races were not, of course, human—by his definition. They showed possibilities, perhaps, but they had not by any means evolved far enough. And, considering the time span involved in their own progress toward a technological civilization, it is not at all unlikely that the Nipe thinks of technology as something that evolves in a race in the same way that intelligence does—or the body itself.
"So it would not surprise him to find that the Real People of this system were humanoid in shape instead of—ah—Nipoid? A bad word, but it will do for the nonce. To find Real People of a different shape is something new, but he can absorb it because it does not contradict anything he knows.
"But—! Any truly intelligent being that did not obey the Law and follow the Ritual would be a contradiction in terms. For our Nipe has no notion of a Real Person without those characteristics. Without those characteristics, technology is, of course, utterly impossible. Since he sees technology all around him, it follows that there must be Real People around somewhere that have those characteristics. Anything else is unthinkable."
"It seems to me that you're building an awfully involved theory out of pretty flimsy stuff," Stanton said.
Yoritomo shook his head. "Not at all. Not at all. Every scrap and shred of evidence we have points toward it. Why, do you suppose, does the Nipe conscientiously devour his victims, often risking his own safety to do so? Why do you suppose he never uses any weapon but his own hands to kill with?"
Yoritomo leaned forward and speared out at Stanton with a long, bony forefinger. "Why? To tell the Real People that he is a gentleman!"
He sat back with a satisfied smile and puffed complacently at his pipe, remaining silent while Bart Stanton considered his last remark.
"Just one thing," Stanton said after a minute. "It seems to me that he would be able to judge that some races have different Laws and Rituals than he does. Wouldn't they have a science comparable to our anthropology?"
