“The ‘stream’ we call science always flows forward; sometimes reactionary beavers block its flow, but the stream is never defeated by this; it accumulates, gathers strength; its waters get over the barrage and continue on their course. The advancement of science is the advancement of God, for science is nothing but human intelligence, and human intelligence is the most valuable treasure God has bequeathed us.”

“Today evolution of human intelligence has advanced us to the stage where most of us are too smart to invent new gods but are reluctant to give up the old ones.”

“The world changes materially. Science makes advances in technology and understanding. But the world of humanity doesn't change.”

“Science has not yet taught us if madness is or is not the sublimity of the intelligence.”

“From this foul drain the greatest stream of human industry flows out to fertilize the whole world. From this filthy sewer gold flows. Here humanity attains its most complete development and its most brutish, here civilization works its miracles and civilized man is turned almost into a savage.”

“As science advances, there seems to be less and less for God to do. It's a big universe, of course, so He, She, or It, could be profitably employed in many places. But what has clearly been happening is that evolving before our eyes has been a God of the Gaps; that is, whatever it is we cannot explain lately is attributed to God. And then after a while, we explain it, and so that's no longer God's realm.”
