Stephen Breyer: I don’t know better than anyone else, but it’s the number of people. Eventually people will get, I suppose, population under control. But there is a large and growing number of people. They all have to be fed. They all have to be housed. They have to learn. They’re all gonna have families, we hope. They’re all going to have lives. Each one of them is an individual life. And as you have more and more, the great positive thing is people . . . they’re . . . it’s religion, if you like; but people have within them the capacity for great good and for terrible things. And societies come together, churches come together, philosophers come together, people come together with sets of behaviors which we try to teach children so that they’ll get those bad instincts under control. And so we’ll bring out the good ones. And if you’re gonna bring out the good ones, people are capable of marvelous things. I mean just tremendous organization. So that’s why I thought India was so interesting, because I thought, “My goodness. It’s like a microcosm.” And here we have the points of light, and the dangers of darkness. And of course we all know now we can destroy the whole planet. It’s possible. It’s possible. And yet we’re working . . . and that’s why I’m so enthusiastic about these different organizations – whether they’re local, or whether they’re national, or whether they’re international – that are trying to knit things together, that are trying to create structures. So when future people are born in the world, they will have structures within which they can work to try to use their good instincts, their capacities, their abilities, to create worlds that are better. And if you contrast this century with the 19th, in the 19th they were certain that it was progress; but we’ve lived through – I have – this terrible, terrible 20th Century. And now people are not at all certain whether the forces of progress, whether the good within people is so good that it can overcome these tremendous problems. But we’re working on it. So I’m an optimist, and most people are. We work on it. We do our best.
