Science intensifies religious truth by cleansing it of ignorance and superstition.

After my death, the molecules of my being will return to the earth and sky. They came from the stars. I am of the stars.

The idea of racial inferiority or superiority is foreign to me. I can't feel inferior or superior to another man because of race, or in any way antagonistic to him. I judge by the individual, not by his race, and have always done so. I would rather have one of my children marry into a good family of any race than into a bad family of any other race.

I may be flying a complicated airplane, rushing through space, but in this cabin I'm surrounded by simplicity and thoughts set free of time. How detached the intimate things around me seem from the great world down below. How strange is this combination of proximity and separation. That ground - seconds away - thousands of miles away. This air, stirring mildly around me. That air, rushing by with the speed of a tornado, an inch beyond. These minute details in my cockpit. The grandeur of the world outside. The nearness of death. The longness of life.

Then what am I - the body substance which I can see with my eyes and feel with my hands? Or am I this realization, this greater understanding which dwells within it, yet expands through the universe outside; a part of all existence, powerless but without need for power; immersed in solitude, yet in contact with all creation? There are moments when the two appear inseparable, and others when they could be cut apart by the merest flash of light.

Science, freedom, beauty, adventure: what more could you ask of life?
