Yeah, anybody asks me about it, my advice was always, do not do it. In fact, it still is. Somebody just asked me last week, I was like, do not do it.

The sky has turned brighter. There is a glorious rainbow that beckons those with the spirit of adventure. And there are rich findings at the end of that rainbow. To the young and the not too old, I say, look at the horizon, find that rainbow, go ride it. Not all will be rich; quite a few will find a vein of gold; but all who pursue that rainbow will have a joyous and exhilarating ride and some profit.

So take the time to find the thing that excites you more than anything else in the world. Not the thing your parents want you to do. Or the thing that all your friends are doing. Or that society expects of you.

Certainly, if you want to get into the field of biology these days, you should also study anthropology because so much work now is with communities. How do you help communities? How do you convince communities to protect their environment? — Especially if, let’s say, you have a tiger eating your cows. The natural gesture is to kill that tiger. Well, what are the alternatives? That’s the kind of thing one is now increasingly working with.

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.

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.

That is a difficult question to answer because I’ve worked in so many fields. I’ve worked in five different fields. Now which are the most important? In some ways, the development of the biological species concept, which I did not invent, but I certainly was the person that brought it to general knowledge. And the whole field of new systematics — I really am the one who developed it — was one of my major contributions. There’s another one, which is still not yet realized by almost anybody. I have done more, I believe, for the development of a philosophy of biology than any other person.

Birds are still very much my hobby

Anyhow, I talked it over with my mother, and she said, “Well, if that’s what you want, go right ahead.” She was a wonderful woman. And so I did.

Unfortunately I have too many projects going. Two of them, fortunately, are already in the editors’ hands. One is this book on the birds of Northern Melanesia I’m doing with Jared Diamond, and that deals with speciation and particular ecology, biogeographic dispersal and all the other questions.
