I never liked doing things systematically. Not even my Ph.D. research was done systematically. It was done in a random, haphazard fashion. The more I got on, the more I felt that, really, one can find something only in that way—in the same way in which, say, a dog runs through a field. If you look at a dog following the advice of his nose, he traverses a patch of land in a completely unplottable manner. And he invariably finds what he is looking for. I think that, as I’ve always had dogs, I’ve learned from them how to do this. So you then have a small amount of material and you accumulate things, and it grows, and one thing takes you to another, and you make something out of these haphazardly assembled materials. And, as they have been assembled in this random fashion, you have to strain your imagination in order to create a connection between the two things. If you look for things that are like the things that you have looked for before, then, obviously, they’ll connect up. But they’ll only connect up in an obvious sort of way, which actually isn’t, in terms of writing something new, very productive. You have to take heterogeneous materials in order to get your mind to do something that it hasn’t done before.
