My knowledge of science came from being with Carl, not from formal academic training. Carl gave me a thrilling tutorial in science and math that lasted the 20 years we were together.

Well, I actually grew up in the sixties. I feel very lucky, actually, that that was my slice of time that I was dealt. Let's remember that the real motivation in the sixties, and even in the fifties, was the Cold War.

I guess I so desperately want to see us put this planet right. It's so horrifying to me that a fifth of us are starving every night, and that forty thousand children die every single day.

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.

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.

Carl took on the military-industrial complex. He campaigned around the world for an end to the production of weapons of mass destruction. To him it was a perversion of science.
