Say you’re planning a vacation trip to visit the castles of England. You’re thinking maybe you’ll see a castle a day, with lots of time for leisurely drives and exploration in between. Your spouse, meanwhile, has drawn up a rigid schedule that will get you to twenty sites in seven days. In the course of trying, gently, to point out how impractical this is, you ask: “But how can we possibly make it from Harlech to Alnwick in under two hours?”. Your spouse, fed up with this discussion, replies: “We’ll take a rocket ship, okay?”
Actually, of course, your spouse knows perfectly well that you won’t be taking a rocket ship. So: Have you just been lied to? It seems to me that you clearly haven’t been. A lie requires an intent to deceive. You have, perhaps, been treated with contempt, and that can be just as unpleasant as a lie. But it’s not a lie. In order to lie, you’ve got to have some chance of being believed.
When President Obama said that he could provide health care to millions without taking any health care away from people who have already got it, he had no chance of being believed. The statement was absurd on its face. This is a law of arithmetic: If you invite a bunch of friends to share your lunch, there’s going to be less lunch for you. Everybody understands that.
