"The harm, as I’ve said repeatedly, comes not from the existence of religion itself, but from its reliance on and glorification of faith—belief, or, if you will, “trust” or “confidence”—without supporting evidence. And faith, as employed in religion , is a danger to both science and society. The danger to science is in how faith warps the public understanding of science: by arguing, for instance, that science is based just as strongly on faith as is religion; by claiming that revelation or the guidance of ancient books is just as reliable a guide to truth about our universe as are the tools of science; by thinking that an adequate explanation can be based on what is personally appealing rather than on what stands the test of empirical study."

“Can you prove that leprechauns don’t live in my garden? Well, not absolutely, but if you never see one, and they have no effects, than you can provisionally conclude that they don’t exist. And so it is with all the fanciful features and creatures we firmly believe don’t exist.”

“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.”

“The battle for evolution seems never-ending. And the battle is part of a wider war, a war between rationality and superstition.”

“This shows what we already know: belief may arise by indoctrination or authority, but is often maintained by social utility. But if no conceivable evidence can shake your faith in a theistic God, then you’ve deliberately removed yourself from rational discourse. In other words, your faith has trumped science.”

“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?”
