The worst tragedy that could have befallen me was my success. I knew right away that I was through - cast out.

I speak about universal evolution and teleological evolution, because I think the process of evolution reflects the wisdom of nature. I see the need for wisdom to become operative. We need to try to put all of these things together in what I call an evolutionary philosophy of our time.

Wisdom: It's something that you know when you see it. You can recognize it, you can experience it. I have defined wisdom as the capacity to make judgments that when looked back upon will seem to have been wise.

Risks, I like to say, always pay off. You learn what to do, or what not to do.

Life is an error-making and an error-correcting process.
