Jerry Coyne on Faith

"The conflation of faith as “unevidenced belief” with its vernacular use as “confidence based on experience” is simply a word trick used to buttress religion."

"Theology is the post hoc rationalization of what you want to believe."

"This book lays out the main lines of evidence for evolution. For those who oppose Darwinism purely as a matter of faith, no amount of evidence will do—theirs is a belief not based on reason."

"Above all, religion, faith healing, and alternative medicine all show the diagnostic feature of faith: an agenda not to find the truth, but to support one’s biases, emotions, and personal beliefs."

"The question to ask believers is this: “Does it really matter whether what you believe about God is true—or don’t you care?” If it does matter, then you must justify your beliefs; if it doesn’t, then you must justify belief itself."

"Theologians intensely dislike the definition of faith as belief without—or in the face of—evidence, for that practice sounds irrational. But it surely is, as is any system that requires supporting a priori beliefs without good evidence. In religion, but not science, that kind of faith is seen as a virtue."

"I will have achieved my aim if, by the end of this book, you demand that people produce good reasons for what they believe—not only in religion, but in any area in which evidence can be brought to bear. I’ll have achieved my aim when people devote as much effort to choosing a system of belief as they do to choosing their doctor. I’ll have achieved my aim If the public stops awarding special authority about the universe and the human condition to preachers, imams, and clerics simply because they are religious figures. And above all, I’ll have achieved my aim if, when you hear someone described as a “person of faith,” you see it as criticism rather than praise."

"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."

"To a very large extent, which religion you accept and which you reject are accidents of birth. And after you’ve been religious for years, and surrounded by those who believe likewise, you become emotionally invested in your faith’s truth. This makes you more susceptible to confirmation bias and less likely to be skeptical about your beliefs."

"Theodicy is the Achilles Heel of faith. There is no reasonable answer to the problem of gratuitous evil , and the will to continue believing in the face of such things truly shows the folly of faith. For those evils prove absolutely either that God is not benevolent and omnipotent, or that there is no god. . Both nonbelief or belief in a malicious or uncaring God are unacceptable to the goddy. Ergo, any rational person who contemplates gratuitous evil must become an agnostic, an atheist, or someone who rejects the Abrahamic God. It is a touchstone of rationality."

"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."
