He said the person that most challenged his capacity for empathy was Donald Rumsfeld.
He’s confident right now! He doesn’t have to wait 100 or 500 years. He doesn’t care. I really care whether I’m right or wrong. I really do care. And probably for lots of reasons. I don’t want to be seen as a dumbass, I don’t want to be seen as someone who believes in something that’s absolutely false, untrue, something that can’t be substantiated, checked. I believe that there’s some deep virtue in pursuing truth. Maybe it’s the highest virtue. I believe that. Whether you can attain it or not, you can pursue it. It can be a goal. It can be a destination. I don’t believe that’s Donald Rumsfeld’s goal. I believe that Robert S. McNamara really wanted to understand what he had done and why he had done it. You know, we remain a mystery to ourselves, among the many, many, many other mysteries there are. And McNamara’s struggle with his own past — I was deeply moved by it. I think he’s a war criminal, I think he sees himself as a war criminal, but I like him.
