"If science exterminates a disease which has been working for God, it is God that gets the credit and all the pulpits break into grateful advertising-raptures and call attention to how good he is. Yes, he has done it. Perhaps he waited a thousand years before doing it. They forget to say that he is the slowest mover in the universe, that his Eye That Never Sleeps, might as well, since it takes a century to see what any other eye can see in a week."
