Brink Lindsey laments Paul Krugman's "crude partisanship."

How can someone as intelligent and informed as Krugman concoct an interpretation of the post-World War II era that does such violence to the facts? How can someone so familiar with the intricate complexities of social processes convince himself that history is a simple matter of good guys versus bad guys? Because, for whatever reason, he has swapped disinterested analysis and scholarship for ideological partisanship. Here, in a revealing choice of phrase, he paraphrases Barry Goldwater's notorious line: "Partisanship in the defense of liberty is no vice."

To be a partisan is, by definition, to see the world partially rather than objectively: to identify wholeheartedly with the perspectives of one particular group and, at the extreme, to discount all rival perspectives as symptoms of intellectual or moral corruption. . . .

I understand the us-versus-them pleasures of ideological partisanship. In my younger days, I indulged in them with gusto. But at some point, ideology joined Santa Claus and the tooth fairy in my attic of discarded beliefs. Firm values, yes; definite points of view on contested empirical questions, to be sure — but to see a country as diverse, yet blessedly prosperous and stable, as this one as an ongoing war between angels and devils is to live in a fantasy world.
