If you want to save your child from polio, you can pray or you can inoculate....Try science.
Carl SaganA celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism.
Carl SaganPresent global culture is a kind of arrogant newcomer. It arrives on the planetary stage following four and a half billion years of other acts, and after looking about for a few thousand years declares itself in possession of eternal truths. But in a world that is changing as fast as ours, this is a prescription for disaster. No nation, no religion, no economic system, no body of knowledge, is likely to have all the answers for our survival. There must be many social systems that would work far better than any now in existence. In the scientific tradition, our task is to find them.
