A lot of people have this ego need that makes them want to believe that Earth is the center of the universe and humans are the most important species, the supreme expression of creation.

Science is nothing more than a neverending search for the truth.

I've been thinking about the distorted view of science that prevails in our culture. I've been wondering about this, because our civilization is completely dependent on science and high technology, yet most of us are alienated from science.

And what greater might do we possess as human beings than our capacity to question and to learn?

Knowing a deep thing well, which is what science asks of its practitioners, is an empowerment that is very profound. It's a liberation.

Ten long trips around the sun since I last saw that smile, but only joy and thankfulness that on a tiny world in the vastness, for a couple of moments in the immensity of time, we were one.

This planet seems to be in such sorry shape. And I can't ever think about the rest of the universe without coming back home and thinking what the implications for life here would be if we were to really have some definitive proof of extraterrestrial life.
