There is no such thing as a failed experiment, only experiments with unexpected outcomes.

We are not going to be able to operate our Spaceship Earth successfully nor for much longer unless we see it as a whole spaceship and our fate as common. It has to be everybody or nobody.

We must do away with the absolutely specious notion that everybody has to earn a living.

Every child has an enormous drive to demonstrate competence.

Above all, I am motivated by the most mysterious drive we ever experience -that of love - I don't think there's any influence on my life that compares with love.

We were deliberately designed to learn only by trial and error. We're brought up, unfortunately, to think that nobody should make mistakes. Most children get de-geniused by the love and fear of their parents - that they might make a mistake. But all my advances were made by mistakes. You uncover what is when you get rid of what isn't.

The more we learn the more we realize how little we know.
