Science is only a Latin word for knowledge - Carl Sagan, The Varieties of Scientific Experience: A Personal View of the Search for God

"I think the discomfort that some people feel in going to the monkey cages at the zoo is a warning sign."

"Extinction is the rule. Survival is the exception."

"So those who wished for some central cosmic purpose for us, or at least our world, or at least our solar system, or at least our galaxy, have been disappointed, progressively disappointed. The universe is not responsive to our ambitious expectations."

"I would suggest that science is, at least in my part, informed worship."

"It goes with a courageous intent to greet the universe as it really is, not to foist our emotional predispositions on it but to courageously accept what our explorations tell us."
