Mont Quotes
In terms of his personal characteristics, Hayek was a very complicated personality. He was by no means a simple person. He was very outgoing in one sense but at the same time very private. He did not like criticism, but he never showed that he didn't like criticism. His attitude under criticism, as I found, was to say: "Well, that's a very interesting thing. At the moment, I'm busy, but I'll write to you about it more later." And then he never would! On the other hand, he wasn't like von Mises. He wasn't intolerant at all. You cannot conceive of Hayek doing the kind of thing that Mises did, when, for example, he wouldn't talk to Machlup for three years because Machlup had come out for floating exchange rates at a Mont Pelerin meeting. Hayek did not do that. That was, I believe, because of the influence of the London School on him. He was very much tempered by the London School.
