More quotes by Carl Sagan

"[When a religious couple wrote to Sagan about fulfilled prophecies, he wrote back in May 1996:]If ‘fulfilled prophecy’ is your criterion, why do you not believe in materialistic science, which has an unparalleled record of fulfilled prophecy? Consider, for example, eclipses."
"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself."
"There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths."
"You can get into a habit of thought in which you enjoy making fun of all those other people who don't see things as clearly as you do. We have to guard carefully against it."
"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."
