I always chose to surround myself with good people no matter my career. I picked teachers and mentors who promised me a hard life.

I think I have been mentored by many extraordinary judges in my career, but there’s one in particular that probably changed the course of my life on the court. And that’s Justice John Paul Stevens and the one year we overlapped.

It so happened that we had a very good math teacher, who was a Communist. I remember having learned from him something that I never forget: the rule of nines. A simple point: you add up the numerals in a number, and if the original number was divisible by nine, then the sum of the figures also is. For instance, you take a number like 243. Two and four and three is nine. Therefore, 243 must be divisible by nine. Actually it is nine times 27. The rule is interesting because it’s so simple. What was really interesting to us ten-year-olds is that our math teacher proved it. The proof is not terribly difficult, but it was one of the first simple and not quite obvious mathematical proofs that I encountered.

When I became a professional actor I was fortunate to be given my first job there by a director called Jonathan Petherbridge.…He instilled in me a way of thinking about acting, which was about as far away from it being a vain occupation as possible, in that drama has significant possibilities for change in society, however small.

Birds are still very much my hobby

My father had a wonderful library, and we always bought books galore, and I devoured all the books of explorers that went to various places in the world. I admired what Humboldt had done and Bates and Darwin and the Swedish explorers, Sven Hedin and others. I was dreaming all the time about someday being an explorer, going to the tropics, going to the jungles, seeing new things, discovering strange animals and so forth, but of course it was a dream world.

Now look here, young man. If you become a medical doctor you will never have a chance to go to the tropics, you will be far too busy.

The interests of a person plays a considerable role. For instance, people who are born naturalists should choose different professions than people who have a spectacular mathematical talent. I think it depends on a person’s talent, what he should choose and what he should love. If you don’t love what you’re doing, you’re not going to do a good job.

And I still remember, and that's the honest truth, as we were leaving his office, he said, 'Well, I give you a fifty-fifty chance to come out alive'. That was Malaita at that time, and... and you can check in the books and will find that that was the... that's why nobody had ever collected there. Well, we made the first collection.

What in a way pleases me and makes me very proud, and I probably shouldn't be, is that I am an honorary fellow of the five oldest academies of the world, all five of them and I don't know whether there's anybody else who can say that.
