HARRIS In language translation, you may get a literally accurate word-for-word translation ... but miss the meaning entirely. And in space-type translation ... the effect may be the same! ever been in. But that was only natural, he told himself sadly the Tr'en were an efficient people. All the preliminary reports had agreed on that their efficiency, as a matter of fact, was what had made Korvin's arrival a necessity. They were well into the atomic era, and efficient physical scientists of the Tr'en—and that would mean, in An invitation, the Comity was sure, which the Tr'en would not accept. isolation, with nothing to do but explore the resources of his own mind. He'd tried some of the ancient Rhine experiments, but that was no good he still didn't show any particular psi talents. He couldn't to the wonder and amazement of his Tr'en captors. He could do, as a matter of fact, precisely nothing. He wished quietly that the Tr'en had seen fit to give him a pack of cards, or a book, or even a folder of tourist pictures. The Wonders of Tr'en, according to would at least have been other prisoners to talk to. But on Tr'en Korvin was all alone. True, every night the guards came in and gave him a concentrated lesson in the local language, but Korvin failed to get much pleasure out of that, being unconscious at the time. But now he was equipped to discuss almost anything from philosophy to plumbing, but there was nobody to discuss it with. He changed position on the bunk and stared at the walls. The Tr'en were efficient there weren't even any imperfections in the smooth surface to distract him. He wasn't tired and he wasn't hungry his captors had left him with a full stock of food concentrates. But he was almightily bored, and about ready to tell anything to The Tr'en was tall, and slightly green. It was a ritual, Korvin had learned. "You are of the Tr'en," he the door behind him. Korvin thought of jumping the Tr'en, but decided there might be almost anything else hidden and ready to fire on him. "What do you want with me?" Korvin said. The Tr'en speech—apparently there was only one language on the planet—was stiff and slightly awkward, but easily enough learned under drug hypnosis it was the most rigorously logical construction of its kind Korvin had ever come "I am leaning against the door," Didyak said. The Tr'en literalist as it did the disclosure of the Tr'en fifty-eight teeth, mostly you." It wasn't quite "talk" that was a general word in the Tr'en language, and Didyak had used a specific meaning, roughly: "gain information from, by peaceful and vocal means." Korvin filed it away for future reference. "Why did the Ruler not come to me?" Korvin asked. commands of the Ruler of the Tr'en—and remove the Tr'en threat from contrast of the Tr'en themselves were figured in. Korvin wasn't attempting to escape. He wasn't pleading with the Ruler. He wasn't defying the Ruler, either. He was just answering questions. The Tr'en liked to have everything clear. They were a logical race. The Ruler had started with Korvin's race, his name, his sex—if under four feet." He used the Tr'en measurement scale, of course "A clumsy lie," the Ruler said. "The ship crashed our examinations straps. It was obviously a form of lie-detector—and Korvin felt himself marveling again at this race. Earth science had nothing to match their enormous command of the physical universe adapting a hypnopædic language-course to an alien being so quickly had been wonder enough, but adapting the perilously delicate mechanisms that necessarily made up any lie-detector machinery was almost a miracle. The Tr'en, under other circumstances, would have been a valuable addition to the Comity of Nations. Being what they were, though, they could only be a menace. And He hoped the lie-detector had been adjusted correctly. If it showed him telling an untruth, he wasn't likely to live long, and his receiving it. "You will tell an untruth now," he said. "Are you to him. But, after all, the Tr'en knew their business, better than anyone else could know it. They had the technique and the logic and the training. He hoped they were right. ship crashed?" The Tr'en word, of course, wasn't The Ruler roared. "Do not waste time with the obvious!" he shouted. "Do not try to trick us we are a logical and scientific race! Answer correctly." "I have told the truth," Korvin said. "But it is not—not the truth we want," the Ruler said. know that there was more than one kind of truth. Surely the truth is the truth, just as the Ruler is the Ruler?" "I—" The Ruler stopped himself in mid-roar. "You try to confuse the Ruler," he said at last, in an approximation of his usual one. "But the Ruler will not be confused. We have experts in matters of logic"—the Tr'en word seemed to mean right-saying that their captor was strapped down in the lie-detector. The Ruler translated—"attempts will get you nowhere." Korvin devoutly hoped so. The experts in logic arrived shortly, and in no uncertain terms Korvin was given to understand that logical paradox was not going to confuse were so much primer material for the Tr'en. "They can be treated mathematically," one of the experts, a small emerald-green being, told Korvin thinly. "Of course, you would not understand the mathematics. But that is not important. You need only understand that we cannot be "Sometimes," Korvin said. "It has other names?" the Ruler said. "It has no name," Korvin said truthfully. The Tr'en idiom was like the Earthly one and certainly a planet had no name. People attached names the logical Tr'en had determined to begin from the beginning, instead "It can be described," Korvin said. "Then you will suffer unpleasant consequences if you describe it to Korvin noticed that the Tr'en were becoming slightly puzzled they were no longer moving and speaking with calm assurance. confuse us," he said. Korvin shook his head earnestly. "I am attempting," he said, "not to confuse you." "Then I ask for an answer," the Ruler said. won't understand it." The Ruler frowned. "We shall understand," he said. "Begin. Who governs you?" expression. They needed no words the lie-detector was telling them, perfectly obviously, that he was speaking the truth. But the truth wasn't making any sense. "I told you you wouldn't understand it," he said. "It is a defect in your explanation," the Ruler almost snarled. It wasn't very difficult he hadn't thought it would be. Even the most That couldn't be done by the subconscious mind the conscious had to intervene somewhere. And it couldn't. problem was insoluble. And the Tr'en weren't capable of that sort of thinking. Korvin thanked his lucky stars that their genius had been restricted to the physical and mathematical. Any insight at all into the mental sciences would have given them the key to his existence, and his entire plan, within seconds. But, then, it was lack of that insight that had called for this particular plan. That, and the political structure of the Tr'en. The same lack of insight let the Tr'en subconscious work on his He set his course, relaxed, and cleared his mind. He had no psionic talents, but the men at Earth Central did he couldn't receive the Tr'en aren't about to come can't digest it and stay what they are obeying laws that make things inconvenient for us? Sheer self-interest, of course—but try to make a Tr'en see it! With one government and one language, they just weren't equipped for translation. They were too efficient physically to try for the mental sciences at all. No mental sciences, no insight into my mind or their own—and that means no translation. But—damn it—I wish I were home already.
