"Although this book deals with the conflict between religion and science, I see this as only one battle in a wider war—a war between rationality and superstition. Religion is but a single brand of superstition , but it is the most widespread and harmful form of superstition. And science is but one form of rationality , but it is a highly developed form, and the only one capable of describing and understanding reality."

“In the end theologians are jealous of science, for they are aware that it has greater authority than do their own ways of finding “truth”: dogma, authority, and revelation. Science does find truth, faith does not.”

“Remember three things about censorship. First, it doesn’t work to suppress art or words that you don’t like. Second, trying to censor something just arouses interest in it, as well as resentment towards those who try to tell others what they can or cannot see. Third, exhibiting art or recommending that students read a book does not mean an endorsement of the image or contents.”

“After all, what new insights has religion produced in the last century?”
