Well, it wasn’t a game to me. We were taught, interestingly enough, given the current state of political affairs, that you should try not to hate anyone, that hatred was a sickness and a weakness, and that there were very few people who were completely evil, so you should go out of your way to figure out what makes them tick and see if you can find some way to communicate with them. I learned that more with my family — even before I was old enough to know what I was doing —when I was eating meals, my grandmother’s brother and his family had — they had four kids, and they always fed a lot of people, and we ate there a lot, and they would talk about whatever had happened that week. And the kids could talk, but they had to prove they could listen first, so before I could tell a story I had to recount what I had just heard, because if you weren’t listening, nobody wanted to listen to you. And it was like a primer in human nature, and I was fortunate in having people all along the way who tried to help explain other people to me, and I developed an obsessive interest in doing it.

I was very, very thorough, making sure I really understood how that telescope worked, and that it was working properly. I was quite convinced that I wasn't clever enough to be in Cambridge and would be thrown out at some stage. My policy was to work as hard as I could so that I'd know I'd done my best. We now label this as impostor syndrome, but we didn't recognise, and certainly didn't name it, back then.

I find that you’re a completely different person as a maker than you are as a listener. That’s one of the reasons I so often leave the studio to listen to things. A lot of people never leave the studio when they’re making something, so they’re always in that maker mode, screwdriving things in - adding, adding, adding. Because it seems like the right thing to be doing in that room. But it’s when you come out that you start to hear what you like.

I always have, in my expeditions, people who are academically far cleverer than I am, and even technically, far more competent. So if you want to lead an expedition, in a sense, you’ve got to keep ahead of them. These bright, competent characters you have with you who are marvelous to have on the expedition. And I’ve always found you can do that by, each night, when you go to bed, just let your mind dwell on the likely things that may happen next day, and think out carefully the sort of decisions that might be necessary to make in order to have the program carried through. So next day, when something happens, you’re the one that’s thought about it and you’re the one who has the ideas.

Do I have a muse? Well, I don’t know if this is an adequate answer, but I suppose my muse is the people of South Africa. I’ve often said that the little — or maybe the lot — I know about loving and hating was taught me by South Africa. Now that’s a big debt. When you owe that much to a situation that has shaped your conscience, your heart, your whole life, you’re profoundly indebted.

I don’t think I could. Of course I’m saying this on American soil. I’m facing a few more months of work in this city, but at the end of it, I will be returning to South Africa. I would like to believe that if for some reason the situation deteriorated to the point where I was told, “If you leave South Africa, you can never come back,” I’d stay there. There were periods in my life when I could have been seduced away. I am incredibly fortunate that the government took away my passport at the point when I was most open to seduction. With my passport gone, I could have left on a one-way ticket. But the issue was so starkly highlighted that I had no problem in saying, “No.”
