"His mind employed them without criticism."

Enemies of the people. That was a phrase he might omit. That was a catch phrase he would skip. That was one thing that sleeping with Maria had done. He had gotten to be as bigoted and hidebound about his politics as a hard-shelled Baptist and phrases like enemies of the people came into his mind without his much criticizing them in any way. Any sort of clichés both revolutionary and patriotic. His mind employed them without criticism. Of course they were true but it was too easy to be nimble about using them. But since last night and this afternoon his mind was much clearer and cleaner on that business. Bigotry is an odd thing. To be bigoted you have to be absolutely sure that you are right and nothing makes that surety and righteousness like continence. Continence is the foe of heresy.

—Ernest Hemingway, For Whom the Bell Tolls (1940)
