We may be living at that moment, on the cusp, when we go from being a species that feels a kind of loneliness in the cosmos to actually one sometime in the not too distant future being able to confirm the existence of other intelligent life.

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

If you have a beating heart, that's good enough.

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.

Science reserves the highest reward for those of you who disprove our most cherished beliefs. At any moment someone from any walk of life could come forward and be responsible for a complete revision of our view of everything.

It is a great tragedy that science, this wonderful process for finding out what is true, has ceded the spiritual uplift of its central revelations: the vastness of the universe, the immensity of time, the relatedness of all life, and life's preciousness on our tiny planet.

I found that it was easiest to convey the information in the context of the life of the scientist or in the context of our own personal experience, and there was no idea that was too complicated that couldn't be explained clearly and directly.
