Quotes like “Darwin made it possible to be an intellectually fulfilled atheist” and “Biology is the study of complicated things that give the appearance of having been designed for a purpose” are right up there, but my all-time favorite is “Even if there were no actual evidence in favor of the Darwinian theory, we should still be justified in preferring it over all rival theories.†(All these quotes are from The Blind Watchmaker.)
It’s comforting that evolutionary theory is in the capable hands of rigorous empirical scientists like Dawkins.
