Academy of Achievement interview (1991)
Context: I am interested in a phase that I think we are entering. I call it "teleological evolution," evolution with a purpose. The idea of evolution by design, designing the future, anticipating the future. I think of the need for more wisdom in the world, to deal with the knowledge that we have. At one time we had wisdom, but little knowledge. Now we have a great deal of knowledge, but do we have enough wisdom to deal with that knowledge?

Surefish interview (2002)
Context: A sense of belonging, a sense of being part of a real and important story, a sense of being connected to other people, to people who are not here any more, to those who have gone before us. And a sense of being connected to the universe itself.
All those things were promised and summed up in the phrase, 'The Kingdom of Heaven'. But if the Kingdom is dead, we still need those things. We can't live without those things because it's too bleak, it's too bare and we don't need to. We can find a way of creating them for ourselves if we think in terms of a Republic of Heaven.
This is not a Kingdom but a Republic, in which we are all free and equal citizens, with — and this is the important thing — responsibilities. With the responsibility to make this place into a Republic of Heaven for everyone. Not to live in it in a state of perpetual self-indulgence, but to work hard to make this place as good as we possibly can.
