....The point is that we’re not just talking about being wrong on specific policy questions. We’re talking about never admitting error, and never revising one’s views. Never being able to say that you were wrong is a serious character flaw even if the consequences of that refusal to admit error fall only on a few people. But moral cowardice should be outright disqualifying in anyone seeking high office.
Think about it. Suppose, as is all too possible, that the next president ends up confronting some kind of crisis — economic, environmental, foreign — undreamed of in his or her current political philosophy. We really, really don’t want the job of responding to that crisis dictated by someone who still can’t bring himself to admit that invading Iraq was a disaster but health reform wasn’t.
I still think this election should turn almost entirely on the issues. But if we must talk about character, let’s talk about what matters, namely intellectual integrity.
