"There had been a time when a copy of Trout’s most popular book to date, Plague on Wheels, had brought as much as twelve dollars, because of the illustrations. It was now being offered for a dollar, and people who paid even that much did so not because of the pictures. They paid for the words.
The words in the book, incidentally, were about life on a dying planet named Lingo-Three, whose inhabitants resembled American automobiles. They had wheels. They were powered by internal combustion engines. They ate fossil fuels. They weren’t manufactured, though. They reproduced. They laid eggs containing baby automobiles, and the babies matured in pools of oil drained from adult crankcases.
Lingo-Three was visited by space travelers, who learned that the creatures were becoming extinct for this reason: they had destroyed their planet’s resources, including its atmosphere. The space travelers weren’t able to offer much in the way of material assistance. The automobile creatures hoped to borrow some oxygen, and to have the visitors carry at least one of their eggs to another planet, where it might hatch, where an automobile civilization could begin again. But the smallest egg they had was a forty-eight pounder, and the space travelers themselves were only an inch high, and their space ship wasn’t even as big as an Earthling shoebox. They were from Zeltoldimar. The spokesman for the Zeltoldimarians was Kago. Kago said that all he could do was to tell others in the Universe about how wonderful the automobile creatures had been. Here is what he said to all those rusting junkers who were out of gas: “You will be gone, but not forgotten.” The illustration for the story at this point showed two Chinese girls, seemingly identical twins, seated on a couch with their legs wide open.
So Kago and his brave little Zeltoldimarian crew, which was all homosexual, roamed the Universe, keeping the memory of the automobile creatures alive. They came at last to the planet Earth. In all innocence, Kago told the Earthlings about the automobiles. Kago did not know that human beings could be as easily felled by a single idea as by cholera or the bubonic plague. There was no immunity to cuckoo ideas on Earth. And here, according to Trout, was the reason human beings could not reject ideas because they were bad: “Ideas on Earth were badges of friendship or enmity. Their content did not matter. Friends agreed with friends, in order to express friendliness. Enemies disagreed with enemies, in order to express enmity. “The ideas Earthlings held didn’t matter for hundreds of thousands of years, since they couldn’t do much about them anyway. Ideas might as well be badges as anything. “They even had a saying about the futility of ideas: ‘If wishes were horses, beggars would ride.’ “And then Earthlings discovered tools. Suddenly agreeing with friends could be a form of suicide or worse. But agreements went on, not for the sake of common sense or decency or self-preservation, but for friendliness. “Earthlings went on being friendly, when they should have been thinking instead. And even when they built computers to do some thinking for them, they designed them not so much for wisdom as for friendliness. So they were doomed. Homicidal beggars could ride.”
