One of the greatest rewards for doing can be the chances it gives to do some more - even better.

When things get bad enough, then something happens to correct the course. And it's for that reason that I speak about evolution as an error-making and an error-correcting process. And if we can be ever so much better - ever so much slightly better - at error correcting than at error making, then we'll make it.

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.

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

I see the triumph of good over evil as a manifestation of the error-correcting process of evolution.

I feel that the greatest reward for doing is the opportunity to do more.

The people - could you patent the sun ?
