"I consider it an extremely dangerous doctrine, because the more likely we are to assume that the solution comes from the outside, the less likely we are to solve our problems ourselves."
"We are star stuff harvesting sunlight."

"The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous.

This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity."
