"Misplaced emphasis. You shouldn't emphasize the event that could have changed history; you should emphasize the changes that could have been made. You're going to end this show you were talking about with a shot of Columbus wading up to the beach with an English flag, aren't you?" "Well, that's the logical ending." "That's the logical beginning," the sandy-haired man contradicted. "And after that, your guest historian comes on; how much time will he be allowed?" "Well, maybe three or four minutes. We can't cut the dramatization too short—" "And he'll have to explain, a couple of times, and in words of one syllable, that what we have seen didn't really happen, because if he doesn't, the next morning half the twelve-year-old kids in the country will be rushing wild-eyed into school to slip the teacher the real inside about the discovery of America. By the time he gets that done, he'll be able to mumble a couple of generalities about vast and incalculable effects, and then it'll be time to tell the public about Widgets, the really safe cigarettes, all filter and absolutely free from tobacco." The waiter arrived at this point, and the sandy-haired man ordered another rye highball. I decided to have another bourbon on the rocks, and the TV impresario said, "Gin-and-tonic," absently, and went into a reverie which lasted until the drinks arrived. Then he came awake again. "I see what you mean," he said. "Most of the audience would wonder what difference it would have made where Columbus would have gotten his ships, as long as he got them and America got discovered. I can see it would have made a hell of a big difference. But how could it be handled any other way? How could you figure out just what the difference would have been?" "Well, you need a man who'd know the historical background, and you'd need a man with a powerful creative imagination, who is used to using it inside rigorously defined limits. Don't try to get them both in one; a collaboration would really be better. Then you work from the known situation in Europe and in America in 1492, and decide on the immediate effects. And from that, you have to carry it along, step by step, down to the present. It would be a lot of hard and very exacting work, but the result would be worth it." He took a sip from his glass and added: "Remember, you don't have to prove that the world today would be the way you set it up. All you have to do is make sure that nobody else would be able to prove that it wouldn't."
