I take it all back. I take it all back. There are certain kinds of men in every field that I can talk to as well as I can talk to a good scientist. I met a historian, a writer of history from France once, and had a marvellous conversation with him. Maurois, his name was, André Maurois. And then I met an artist, Robert Irwin, who’s a very important artist in Los Angeles, in modern art, and I could talk to him at the same depth of excitement.

So I take it all back. If you give me the right man, in any field, I can talk to him. I know what the condition is: that he did whatever he did as far as he can go, that he studied every aspect of it, that he has stretched himself to the end. He’s not a dilettante in any way. Therefore he’s up against mysteries all the way around the edge. We can talk about mystery and awe. That’s what we have in common.
