“Science is far from a perfect instrument of knowledge. It's just the best we have. In this respect, as in many others, it's like democracy. Science by itself cannot advocate courses of human action, but it can certainly illuminate the possible consequences of alternative courses of action.”

“Science cuts two ways, of course; its products can be used for both good and evil. But there's no turning back from science.”

“Have the best course for all your actions.”

“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.”

“Incidentally, it's best not to argue with the nursing staff. I find the best course of action is to throw some chocolates in one direction and hurry off in the other while their attention is distracted.”

“Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.”
