I have come to recognize evolution not only as an active process that I am experiencing at the time, but as something I can guide by the choices I make.

What is … important is that we — number one: Learn to live with each other. Number two: try to bring out the best in each other. The best from the best, and the best from those who, perhaps, might not have the same endowment. And so this bespeaks an entirely different philosophy — a different way of life — a different kind of relationship — where the object is not to put down the other, but to raise up the other.

I do what I feel impelled to do, as an artist would. Scientists function in the same way. I see all these as creative activities, as all part of the process of discovery. Perhaps that's one of the characteristics of what I call the evolvers, any subset of the population who keep things moving in a positive, creative, constructive way, revealing the truth and beauty that exists in life and in nature.

As a child I was not interested in science. I was merely interested in things human, the human side of nature, if you like, and I continue to be interested in that. That's what motivates me.

There is no such thing as failure, there's just giving up too soon.

It is possible to create an epidemic of health which is self-organizing and self-propelling.

The most important question we must ask ourselves is, 'Are we being good ancestors?'
