" "[Science] works. It is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are
worthless. Second: whatever is inconsistent with the facts must be discarded or revised. We must understand the Cosmos as it is and not confuse how it is with how we wish it to be. The obvious is sometimes false; the unexpected is sometimes true.

About Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Additional quotes by Carl Sagan
But we have no [Marian] apparitions cautioning the Church against, say, accepting the delusion of an Earth-centered Universe, or warning it of complicity with Nazi Germany — two matters of considerable moral as well as historical import....
Not a single saint criticized the practice of torturing and burning “witches” and heretics. Why not? Were they unaware of what was going on? Could they not grasp its evil? And why is [the Virgin] Mary always admonishing the poor peasant to inform the authorities? Why doesn’t she admonish the authorities herself? Or the King? Or the Pope?
