For those inclined to give Illinois Sen. Dick Durbin a pass on his remarks this past week comparing alleged bad behavior at Gitmo to the Holocaust, the Gulag, and the Cambodian Killing Fields, I link to George Orwell's Politics and the English Language.
Consider this: "A man may take to drink because he feels himself to be a failure, and then fail all the more completely because he drinks. It is rather the same thing that is happening to the English language. It becomes ugly and inaccurate because our thoughts are foolish, but the slovenliness of our language makes it easier for us to have foolish thoughts."
And this: "When one watches some tired hack on the platform mechanically repeating the familiar phrases -- bestial, atrocities, iron heel, bloodstained tyranny, free peoples of the world, stand shoulder to shoulder -- one often has a curious feeling that one is not watching a live human being but some kind of dummy ... And this is not altogether fanciful. A speaker who uses that kind of phraseology has gone some distance toward turning himself into a machine. The appropriate noises are coming out of his larynx, but his brain is not involved ...."
But read the whole thing. It will do wonders for your prose.
