There is hope in dreams, imagination, and in the courage of those who wish to make those dreams a reality.

It is courage based on confidence, not daring, and it is confidence based on experience.

Solutions come through evolution. They come through asking the right questions, because the answers pre-exist. It is the questions that we must define and discover. You don't invent the answer-you reveal the answer.

It is said to await certainty is to await eternity.

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.

A wisdom deficit - fewer elders and even fewer people who listen to them.

I think of evolution as an error-making and error-correcting process, and we are constantly learning from experience.
