“I judge things from an evolutionary perspective — "How does this serve and contribute to the process of our own evolution?" — rather than think of good and evil in moral terms. I see the triumph of good over evil as a manifestation of the error-correcting process of evolution.”

“The idea of being constructive, creative, positive, in trying to bring out the best in one's own self and the best in others follows from what I've just been saying. Again, I repeat my belief in us, in ourselves, as the product of the process of evolution, and part of the process itself. I think of evolution as an error-making and error-correcting process, and we are constantly learning from experience. It's the need to dedicate one's self in that way, to one's own self, and to choose an activity or life that is of value not only to yourself but to others as well.”

“I have the impression that the new generation of young people, are coming up on the scene with a sense "ancestorhood", and with more wisdom than was evident before. I think this comes about as a matter of necessity — Almost as if there is something in us that is innate, something inherent in us, that is destined for a longer term, rather than a shorter term future.”

“Neither wisdom nor good will is now dominant. Hope lies in dreams, in imagination and in the courage of those who dare to make dreams into reality.”

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

“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?”
