You don't get to advertise all the good that your religion does without first scrupulously subtracting all the harm it does and considering seriously the question of whether some other religion, or no religion at all, does better.
Daniel DennettIf I were to give a prize for the single best idea anybody ever had, I'd give it to Darwin for the idea of natural selection - ahead of Newton, ahead of Einstein - because his idea unites the two most disparate features of our universe: the world of purposeless, meaningless matter and motion, particles jostling on the one side, and the world of meaning and purpose, design on the other.
