I think it will clear up this discussion if everybody knows how exactly Newt Gingrich was quoting Camus. This is what he said:

> So as the Polish people were struggling with the Soviet empire, they came up with a slogan: "Two plus two equals four." They printed it up. They put it on signs. They put it in the front door. And the Soviets knew it was somehow treasonous, but they couldn't -- how do you walk in a store and say, "You can't have 'Two plus two equals four' in the window"?

It came from two places. One was Camus' novel, "The Plague," in which Camus says there are times when a man can be killed for saying two plus two equals four, because the authorities can't stand the truth. I think you'll find more than enough occasion in Washington, in Sacramento, in Albany, in city hall, in county commissions, that they can't stand the truth.
