Wisdom: It's something that you know when you see it. You can recognize it, you can experience it. I have defined wisdom as the capacity to make judgments that when looked back upon will seem to have been wise.

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

My life is pretty well at peace, and the profession is more of an avocation. It's a calling, if you like, rather than a job. I do what I feel impelled to do, as an artist would.

Life is an error-making and an error-correctin g process, and nature in marking man's papers will grade him for wisdom as measured both by survival and by the quality of life of those who survive.

The worst tragedy that could have befallen me was my success. I knew right away that I was through - cast out.

If all insects disappeared, all life on earth would perish. If all humans disappeared, all life on earth would flourish.

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