MANNERS AND CUSTOMS OF THE THRID BY MURRAY LEINSTER The Thrid were the wisest creatures in space—they even said so themselves! [Transcriber's Note: This etext was produced from But also, and contradictorily, he saw them as right and just, or as on business and never bothered about Ganti. As a believer in right and wrong, it would have been wiser for him to have stayed off the planet Thriddar altogether. Thriddar was no place for him, anyhow you look at it. On this particular morning it was especially the wrong place for him to be trying to live and do business. He woke up thinking of Ganti, and in consequence he was in a bad mood right away. Most humans couldn't take the sort of thing that went on on Thriddar. Most of them wanted to use missile weapons—which the Thrid did not use—to change the local social system. Most humans got off Thriddar—fast! And boiling mad. Jorgenson had stood it longer than most because in spite of their convictions he liked the Thrid. Their minds did do outside loops, and come up with intolerable convictions. But they were intelligent enough. didn't have missile weapons and they did have a social system that humans simply couldn't accept—even though it applied only to Thrid. The ordinary Thrid, with whom Jorgenson did business, weren't bad Panjandrum—the term was Jorgenson's own for the supreme ruler over all the Thrid—and when Jorgenson finished his breakfast a high Thrid other Thrid, wearing the formal headgear that said they were Witnesses to an official act. suspicious at once. The words of a current Grand Panjandrum were always written in gold. If they didn't get written in gold they didn't get written at all Never-Mistaken Glen-U speak and say and observe a truth in the presence worse than that. He couldn't make a mistake. Whatever he said had to be true, because he said it, and sometimes it had drastic results. But by the operation of truth, vanish from sight and nevermore be seen face A part of this was reaction as a business man. A part was recognition of all the intolerable things that the Thrid took as a matter of not have left any trade-goods behind—and left the Grand Panjandrum to realize what he had lost when no off-planet goods arrived on Thriddar. In time he'd speak and say and observe that he, out of his generosity, feel only like a business man this morning. He thought of Ganti, who was a particular case of everything he disliked on Thriddar. It was not wise to be moved by such sympathetic feelings. The Grand Panjandrum could not be mistaken. It was definitely unwise to "I will receive the moneys, goods, and benefactions it is the desire There was an idiom in Thrid speech that had exactly the meaning of the contradicted the Grand Panjandrum! Nobody! The Thrid had noticed long ago that they were the most intelligent race in the universe. Since that was so, obviously they must have the most perfect government. no Thrid official ever made a mistake. In particular the great and thing, it was true! It had to be! He'd said it! And this was the fundamental fact in the culture of the Thrid. "Like hell you'll receive moneys and goods and such!" snapped said is not true!" This was the equivalent of treason, blasphemy and give itself to the Never-Mistaken Glen-U, who was the Grand Panjandrum of Thriddar. He waited to be told that it couldn't have happened that anyhow it couldn't be intended. But the theologian's Thriddish ears Thrid just like you are! Of course he can make a mistake! There's unknown consequences for any Thrid who might be nearby. and a—call it—theology it wasn't his business to change. True, the Thrid way of life was appalling, and what had happened to Ganti was probably typical. But it wasn't Jorgenson's affair. He'd been unwise to let it disturb him. If the Thrid wanted things this way, it was their privilege. In theory, no Thrid should ever make a mistake, because he belonged was even more intelligent. If an ordinary Thrid challenged a local governor's least and lightest remark—why—he must be either a criminal of criminals chained together and doing the most exhausting labor the Thrid could contrive. If he was mad, he was confined for life. There'd been Ganti, a Thrid of whom Jorgenson had had much hope. He believed that Ganti could learn to run the trading post without human supervision. If he could, the trading company could simply bring trade goods to Thriddar and take away other trade goods. The cost of doing business would be decreased. There could be no human-Thrid friction. Jorgenson had been training Ganti for this work. to him, and he almost doubted that an official was necessarily right. dinner, and ate. Afterward he went up on the trading-post roof to smoke and to coddle his anger. He observed the sunset. There was always some haze in the air on Thriddar, and the colorings were very beautiful. He could see the towers of the capital city of the Thrid. He could see a cumbersome but still graceful steam-driven aircraft descend heavily to Now that the new Grand Panjandrum had moved against him, Jorgenson made an angry, dogged resolution to do something permanent to make matters better. For the Thrid themselves. Here he thought not as a business man only, but as a humanitarian. As both. When a whim of the Grand Panjandrum could ruin a business, something should be done. And when He reflected with grim pleasure that the Grand Panjandrum would soon be in the position of a Thrid whom everybody knew was mistaken. With operation of truth, which was really an anesthetic gas cloud drifted "It will not be long," said a tranquil voice. Jorgenson changed from human-speech profanity to Thrid. He directed his words to the unseen creature who'd spoken. That Thrid listened, apparently without emotion. When Jorgenson ran out of breath, the voice Thrid voice—amazingly, a familiar Thrid voice—said: "This is not good, Jorgenson. Who did you contradict?" The Thrid was Ganti, of whom Jorgenson had once had hopes as a business man, and for whose disaster he had felt indignation as something else. probably forgotten by now." He was calm about it. Only a Thrid would have been so calm. But they've had at least hundreds of generations in which to get used to injustice. He racked his brains for the most preposterous or faintest hope of deliverance. There were times when as a business man he reproached himself for staying on Thriddar after he became indignant with the way the planet was governed. It was very foolish. But much more often he felt such hatred of the manners and customs of the Thrid—which had put him here—that it seemed that something must somehow be possible if only so he could take revenge. something he'd never noticed before, he told of the incredible conditioning-education of the young members of his race. They learned not to have any opinion particular meaning. But he was also a person, filled with hatred of the Thrid who had condemned him for life to this small island. He saw He did not speak at all during all the rest of that day. He was thinking. The matter needed much thought. Ganti left him alone. But by sunset he'd worked it out. While they watched Thrid's red sun sink below the horizon, Jorgenson said thoughtfully: We can make better weapons than they have." Ganti looked skeptical. Jorgenson explained. He had to demonstrate crudely. The whole idea was novel to Ganti, but the Thrid were smart. Presently he grasped it. He said: left upon a morsel of rock in a boundless sea, rehearsing themselves in an art so long-forgotten that they had to reinvent the finer parts
