“Your frequent claim that we must understand religious belief as a “social construct,” produced by “societal causes,” dependent upon “social and cultural institutions,” admitting of “sociological questions,” and the like, while it will warm the hearts of most anthropologists, is either trivially true or obscurantist. It is part and parcel of the double standard that so worries me—the demolition of which is the explicit aim of The Reason Project.Epidemiology is also a “social construct” with “societal causes,” etc.—but this doesn’t mean that the germ theory of disease isn’t true or that any rival “construct”—like one suggesting that child rape will cure AIDS—isn’t a dangerous, deplorable, and unnecessary eruption of primeval stupidity. We either have good reasons or bad reasons for what we believe; we can be open to evidence and argument, or we can be closed; we can tolerate (and even seek) criticism of our most cherished views, or we can hide behind authority, sanctity, and dogma. The main reason why children are still raised to think that the universe is 6,000 years old is not because religion as a “social institution” hasn’t been appropriately coddled and cajoled, but because polite people (and scientists terrified of losing their funding) haven’t laughed this belief off the face of the earth.We did not lose a decade of progress on stem-cell research in the United States because of religion as a “social construct”; we lost it because of the behavioural and emotional consequences of a specific belief. If there were a line in the book of Genesis that read – “The soul enters the womb on the hundredth day (you idiots)” – we wouldn’t have lost a step on stem-cell research, and there would not be a Christian or Jew anywhere who would worry about souls in Petri dishes suffering the torments of the damned. The beliefs currently rattling around in the heads of human beings are some of the most potent forces on earth; some of the craziest and most divisive of these are “religious,” and so-dubbed they are treated with absurd deference, even in the halls of science; this is a very bad combination—that is my point. ”

“Race is different purely as a social construction, not as inherent difference. And religion - whether you believe in God or Yahweh or Allah or something else, odds are that at heart you want the same things. For whatever reason, we like to focus on the 2 percent that's different, most of the conflict in the world comes from that.”

“Each religion makes scores of purportedly factual assertions about everything from the creation of the universe to the afterlife. But on what grounds can believers presume to know that these assertions are true? The reasons they give are various, but the ultimate justification for most religious people’s beliefs is a simple one: we believe what we believe because our holy scriptures say so. But how, then, do we know that our holy scriptures are factually accurate? Because the scriptures themselves say so. Theologians specialize in weaving elaborate webs of verbiage to avoid saying anything quite so bluntly, but this gem of circular reasoning really is the epistemological bottom line on which all 'faith' is grounded. In the words of Pope John Paul II: 'By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals.' It goes without saying that this begs the question of whether the texts at issue really were authored or inspired by God, and on what grounds one knows this. 'Faith' is not in fact a rejection of reason, but simply a lazy acceptance of bad reasons. 'Faith' is the pseudo-justification that some people trot out when they want to make claims without the necessary evidence.But of course we never apply these lax standards of evidence to the claims made in the other fellow’s holy scriptures: when it comes to religions other than one’s own, religious people are as rational as everyone else. Only our own religion, whatever it may be, seems to merit some special dispensation from the general standards of evidence.And here, it seems to me, is the crux of the conflict between religion and science. Not the religious rejection of specific scientific theories (be it heliocentrism in the 17th century or evolutionary biology today); over time most religions do find some way to make peace with well-established science. Rather, the scientific worldview and the religious worldview come into conflict over a far more fundamental question: namely, what constitutes evidence.Science relies on publicly reproducible sense experience (that is, experiments and observations) combined with rational reflection on those empirical observations. Religious people acknowledge the validity of that method, but then claim to be in the possession of additional methods for obtaining reliable knowledge of factual matters — methods that go beyond the mere assessment of empirical evidence — such as intuition, revelation, or the reliance on sacred texts. But the trouble is this: What good reason do we have to believe that such methods work, in the sense of steering us systematically (even if not invariably) towards true beliefs rather than towards false ones? At least in the domains where we have been able to test these methods — astronomy, geology and history, for instance — they have not proven terribly reliable. Why should we expect them to work any better when we apply them to problems that are even more difficult, such as the fundamental nature of the universe?Last but not least, these non-empirical methods suffer from an insuperable logical problem: What should we do when different people’s intuitions or revelations conflict? How can we know which of the many purportedly sacred texts — whose assertions frequently contradict one another — are in fact sacred?”

“There are two ways of persuading men of the truths of our religion; one by the power of reason, the other by the authority of the speaker.We do not use the latter but the former. We do not say: 'You must believe that because Scripture, which says it, is divine,' but we say that it must be believed for such and such a reason. But these are feeble arguments, because reason can be bent in any direction.”

“How is it that, in this one area of our lives [religion], we have convinced ourselves that our beliefs about the world can float entirely free of reason and evidence?”

“People have this belief that what we believe is the effect of the facts that we’re exposed to, and therefore, if we expose people to different and newer facts, they will change their beliefs. This is not true. […]The contents of people’s minds, the belief systems that they hold, are in no way, shape or form a result of any objective evaluation of information. The prejudices are inherited. They are socially inflicted. They are propagandized in school, in church, in communities, in families. They are reinforced by endless bouts of patriotic media and other sorts of nonsense. People are just an emotional Gordian knot, kaleidoscopic clusterfrack of prior prejudices [which have been] stuffed into their heads and held aloft by the spears of social approval or ostracism. Everybody is prejudiced, almost, and everybody maintains those prejudices for fear of social attack, ostracism, or disapproval.Because people haven’t been reasoned into their beliefs, they can’t be reasoned out of their beliefs, [and] when people have existing prejudices, showing them facts that run counter to those prejudices does not dislodge them. In fact, statistically, it is more likely to make those prejudices stronger.”
