“I mean, I enjoy arguing, not in an angry sense, but I love to test the strength of arguments. Because if someone can tell me something that I didn’t know—an argument I hadn’t thought of, or a piece of information I didn’t have—I love it. And people sometimes interpret that—my ex-wife does!—as that I’m bullying people. And that’s not what I think I’m doing. What I think I’m doing is testing the argument, because if someone can give me a good argument, I have no problem about taking it on board. It’s also that I need to understand. I get very frustrated when I don’t understand something. When somebody knows something and I want to understand what it is they know and they can’t explain it in a way which I can take in (which would be my fault), I get very frustrated.”
