But all that changed when Darwin explained those designlike features by natural selection. The best evidence for God simply vanished.

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 (and in most other areas), 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.

The rational scrutiny of religious faith involves asking believers only two questions: How do you know that? What makes you so sure that the claims of your faith are right and the claims of other faiths are wrong?

Every bit of truth clawed from nature over the last four centuries has involved completely ignoring God, for even religious scientists park their faith at the laboratory door.

Now, science cannot completely exclude the possibility of supernatural explanation. It is possible—though very unlikely—that our whole world is controlled by elves. But supernatural explanations like these are simply never needed; we manage to understand the natural world just fine using reason and materialism.

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

No, we don’t have faith in reason and science in the same way as “Cru” members have faith in God. I see “faith” according to Walter Kaufmann’s definition: strong belief in propositions for which there is insufficient evidence to command the assent of every reasonable person. We have confidence in science because it has led us to provisional truths—it works. Cru doesn’t even know if there’s any God, or, if there is a divine presence, that it’s the Abrahamic god rather than the Hindu god, Yahweh, or Wotan. And we use reason in the same way: it leads us to truth. Revelation, dogma, and authority do not, for if they did there would be only one religion rather than thousands with their disparate and often conflicting doctrines.

Accommodationists further accuse scientists of having “faith in reason.” Yet reason is not an a priori assumption, but a tool that’s been shown to work. We don’t have faith in reason; we use reason, and we use it because it produces results and progressive understanding...
Reason is simply the way we justify our beliefs, and if you’re not using it, whether you’re justifying religious or scientific beliefs, you deserve no one’s attention.

Danger! Mushbrains and believers at work!

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 (others include beliefs in astrology, paranormal phenomena, homeopathy, and spiritual healing), but it is the most widespread and harmful form of superstition. And science is but one form of rationality (philosophy and mathematics are others), but it is a highly developed form, and the only one capable of describing and understanding reality.

Our reliance on naturalism, then, is not an assumption decided in advance, but a result of experience—the experience of men like Darwin and Laplace who found that the only way forward was to posit natural rather than supernatural explanations. Because of this success, and the recurrent failure of supernaturalism to explain anything about the universe, naturalism is now taken for granted as the guiding principle of science.

It is curious that those who claim such firm knowledge about God’s nature and works become silent when asked about God’s methods.

The most important component of the incompatibility between science and religion is religion’s dependence on faith.

Come on, readers, give me one example of a question that religion has answered to everyone’s satisfaction—one example of a “truth” found in religion’s quest for truth.

If Hawking’s world is “small,” well, at least what he found was testable, and might be true. Father de Souza’s claims are either untestable or have already been shown to be doubtful, and he has no evidence for any of them. In requiring people to believe fairy tales, de Souza’s world is not just small, but nonexistent.
