More quotes by Carl Sagan

"The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity."
"I don't want to believe. I want to know."
"You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility."
"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself."
"A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism."
