"I have argued that religion is to science as superstition is to reason; indeed, that is the very reason they are incompatible."
"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 oneâs biases, emotions, and personal beliefs."
"If you spend your life looking in vain for the Loch Ness Monster, stalking the lake with a camera, sounding it with sonar, and sending submersibles into its depths, and yet still find nothing, what is the more sensible view: to conclude provisionally that the monster simply isnât there, or to throw up your hands and say, âIt might be there; Iâm not sureâ? Most people would give the first responseâunless theyâre talking about God."
"Itâs important to realize that philosophical naturalism is, like atheism, a provisional view. Itâs not the kind of worldview that says, âI know there is no god,â but the kind that says, âUntil I see some evidence, I donât accept the existence of gods.â"
"The question to ask believers is this: âDoes it really matter whether what you believe about God is trueâor donât you care?â If it does matter, then you must justify your beliefs; if it doesnât, then you must justify belief itself."
"My claim is this: science and religion are incompatible because they have different methods for getting knowledge about reality, have different ways of assessing the reliability of that knowledge, and, in the end, arrive at conflicting conclusions about the universe. âKnowledgeâ acquired by religion is at odds not only with scientific knowledge, but also with knowledge professed by other religions. In the end, religionâs methods, unlike those of science, are useless for understanding reality."
"Our reliance on naturalism, then, is not an assumption decided in advance, but a result of experienceâthe 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."
"Science in fact has a lot to say about the supernatural. It can and has tested it, and so far has found no evidence for it....Indeed, over its history science has repeatedly investigated supernatural claims and, in principle, could find strong evidence for them. But that evidence hasnât appeared."
"You can find some religions without creationism, but you canât find creationism without religion."
"The different claims among these faiths have consequences, for theyâve produce endless misery over the course of history....Clearly, religions arenât incompatible only with science: theyâre incompatible with one another....This farrago of conflicting and irresolvable claims about reality stands in stark contrast to science."
"What I am saying is two things. First, religion hasnât obviously come closer to understanding the divine....I also claim that insofar as theology or religious beliefs do change within a faith, those changes are driven largely by either science or changes in secular culture....Religious morality, at least as promulgated by priests, rabbis, imams, and theologians, is usually one step behind secular morality."
"Although scientists come in all faiths, including no faith at all, there is no Hindu science, no Muslim science, and no Jewish science. There is only science, combining brainpower from the whole world to produce one accepted body of knowledge. In contrast, there are thousands of religions, most differing profoundly in what they see as âtrue.â"
"Theistsâ typical response to these failures (i. e., of prayer to affect rates of healing) is to say either âGod wonât let himself be testedâ or âThatâs not what prayer is about: itâs simply a way to converse with God.â But you can bet that had these studies shown a large positive effect, the religious would be noisily flaunting this as evidence for God. The confirmation bias shown by accepting positive results but explaining away negative ones is an important difference between science and religion."
"These (i. e., the statements of the Nicene Creed) are all empirical statements about reality: they are either true or false, even if some are hard to investigate. These claims, of course, absolutely conflict with those of other faiths. Jews, Muslims, Hindus, and Sikhs donât recognize Jesus as the Messiah. Muslims believe that those who do so will spend eternity in hell. Doesnât choosing among such faiths require a way to evaluate whether this dogma is true?"
"In the end, religious investigations of âtruth,â unlike those of science, are deeply dependent on confirmation bias. You start with what you were taught to believe, or what you want to believe, and then accept only those facts that support your prejudices. This is the basis for the theological practice of âapologetics,â designed to defend religion against counterarguments and disconfirming evidence....In contrast, science has no apologetics, for we test our conclusions by trying to find counterevidence."
"The methodological conflicts between science and religion cannot be brokered, for faith has no reliable way to find truth."
"Living with uncertainty is hard for many people, and is one of the reasons why people prefer religious truths that are presented as absolute."
"But all that changed when Darwin explained those designlike features by natural selection. The best evidence for God simply vanished."
"One canât read a great deal of theology without appreciating the mental dexterity of its practitioners when faced with hard problems. And as a scientist, I regret how much more weâd understand about nature had that dexterity been applied to science instead, or to any field involved in studying whatâs real."
"âWhat distinguishes knowledge is not certainty but evidence.â"
"Claims of supernatural phenomena like the efficacy of prayer are rendered unfalsifiable by the assertion that âGod will not be tested.â (Of course, if the tests had been successful, then testing God would have been fine!)"
"Just as many churches donât want to be seen as rejecting science, neither do they wish to lag too far behind public morality, and so they often tweak their religious âtruthsâ to reflect the zeitgeist."
"Most of the worldâs believers reject these claims (i. e., of Scientology, Mormonism, and Christian Science) as blatantly false. But thatâs only because these three religions are fairly new. They were founded in the last two centuries, and we see their origin not as divine but as obvious fabrications of humansâin the case of Joseph Smith, of a con man. But if you look with equally critical eyes at the doctrines of older faiths, their tenets seem equally bizarre."
"In other words, truth is simply what is: what exists in reality and can be verified by rational and independent observers."
"The most important component of the incompatibility between science and religion is religionâs dependence on faith."
"âBlasphemyâ and âheresyâ are terms of religion, not science."
"âThe interest I have in believing in something is not a proof that the something exists.â"
"To a very large extent, which religion you accept and which you reject are accidents of birth. And after youâve been religious for years, and surrounded by those who believe likewise, you become emotionally invested in your faithâs truth. This makes you more susceptible to confirmation bias and less likely to be skeptical about your beliefs."
"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 youâve deliberately removed yourself from rational discourse. In other words, your faith has trumped science."
"Religion is heavily laden with the kind of confirmation bias that makes people see their own faiths as true and all others as false. In other words, religion is replete with features to help people fool themselves."
"In the end, a theory that canât be shown to be wrong can never be shown to be right."
"In fact, changes like the elimination of limbo donât come from new information, but from secular currents in society that make church dogma seem insupportable or even barbaric."
"Any âknowledgeâ incapable of being revised with advances in data and human thinking does not deserve the name of knowledge."
"Ironically, as the credibility of creationists grows smaller, their voices get louder."
"Well, those opposing extreme gender ideology may be fomenting things, but itâs not because weâre white, religious, or nationalistic. And have these organizations ever considered that there may be many black people or Hispanics who also oppose gender activism? One might even say that blaming all this stuff on white people is a form of racism."
"No, if there is to ever be a two-state solution, the Palestinian side cannot be run by anyone with a history of sponsoring terrorism. And Palestinian leaders like that are hard to find."
"The whole brouhaha serves to demonstrate that âcancel cultureââthe attempt to ruin someoneâs career if they transgress âprogressiveâ ideological standsâis alive and well."
"Itâs funny, but telling, that those who claim that sex is a spectrum or continuum never specify how many sexes there are, either in humans or other species. I suspect that if they respondedâbased on their âmultivariate, multidimensionalâ definition of sexâthat âthere are many, many sexes,â or âI canât answer thatâ, they would be laughed out of the house. But we all know that that the âspectrumâ people are not dumb or willfully ignorant. They are simply imbued with a certain ideology."
"How embarrassing is it, given the situation, that the SSE, the ASN, and the SSB got their biology wrong while the Trump administration got it right! But thatâs what happens when scientific societies get ideologically captured."
"But the important conclusion is that wokeness is here and ubiquitous, and seems entrenched in many areas. But whether or not itâs increasing, it needs to be fought at every turn. And that means that those of us who object to the invidious side of Social Justiceâof course âsocial justiceâ is not all bad; Iâm referring to the PERFORMATIVE AND NON-EFFECTIVE PRETENSE of fixing society by changing words, bird names, and monitoring speech and behaviorâmust stand up and call out this nonsense when we see it, Itâs not pleasant, as youâll be ostracized and demonized, if not fired, but since when was society ever improved without people taking flak from those who wrongly see themselves as the pinnacle of morality?"
"After all, what new insights has religion produced in the last century?"
"One of the purposes of a university is to find the truth, but that canât be done if free discussion is banned."
"But why was the name âJames Webb Space Telescopeâ attacked by Prescod-Weinstein and others? Because of the accusation that, as head of NASA, Webb allowed the demonization of gay employees and oversaw a purge of them from the agency. But as even the NYT reported (October 2022), those accusations are completely false. Will the Offended Woke Physicists give up in light of the evidence and shut their pie-holes about Webb? No, they will not. They still want the name âWebbâ effaced. Itâs insane. The main reason I think this is a tempest in a teapot is because this renaming accomplishes nothing: it is purely performative, which is why itâs woke, and ludicrously so."
"I would add that the kowtowing towards the excesses of Islam by many Westerners is craven, patronizing, and evinces âthe soft bigotry of low expectations.â How dare Westerners excuse or ignore the behavior of countries that execute gays, atheists, and apostates, oppress women and deny them education, and force women to wear coverings so as not to excite the presumably uncontrollable lust of men, while at the same time demonizing Israel, which does none of these things. Itâs because Arabs, even if genetically similar to Israelis, are seen as âpeople of colorâ, while Israelis are seen as âwhite adjacent.â Itâs as if implied pigmentation conferred virtue! These differential views of Arab versus Jewish states constitute one of the most pernicious aspects of Authoritarian Leftism and Wokeism."
"There are no activists so authoritarian and unforgiving as gender activists."
"I really dislike land acknowledgments because theyâre purely performative. They are there to make the issuer look progressive and moral, but they accomplish exactly nothing. And that is what âwokeâ means."
"But none of this criticism of science makes religion even a tiny bit more credible... In contrast, religion has never been right in its claims about the universeâat least not in a way that all rational people can accept. There is no reliable method to show that the Trinity exists, that God is loving and all-powerful, that weâll meet our dead relatives in the afterlife, or that Brahma created the universe from a golden egg. Lacking a way to show its tenets are wrong, religion cannot show them to be right, even provisionally."
"The U.S., for example, has made huge strides in racial equality and racial justice since 1940, but to listen to some Wokesters youâd think that racism now is as bad asâor even worse thanâthe days of Jim Crow. Wokesters claim that itâs just gone underground and has a different form. This, to me, is a ludicrous belief, refuted by tons of evidence."
"I continue to be amazed at how much dust is stirred up by simply asserting the biological observation that, in animals and vacular plants, there are but two sexes, and those sexes are defined by the reproductive equipment they have. Males are âdesignedâ (Iâm speaking teleologically: âevolvedâ is what I mean) to make small, mobile gametes, and females to make big immobile ones. For decades this has been uncontroversial: A truth universally acknowledged, to paraphrase Jane Austen. Now, however, for reasons known best to themselves, a small but vocal group of ideologues is denying the sex binary. In my coauthored paper coming out in late June, we hazard some guesses, but those of you following the controversy probably realize that it involves trying to impose oneâs ideological views onto nature. This doesnât work so easily with the sex binary, as even nonscientists can observe it with their own eyes. The result is that deniers of that binary, such as AgustĂn Fuentes and Laura Helmuth (editor of Scientific American whoâs published several pieces denying a sex binary), face considerable pushback from both scientistsâwho work with male and female organismsâand âregularâ people, who have eyes to see and neurons to analyze."
"The harm, as Iâve said repeatedly, comes not from the existence of religion itself, but from its reliance on and glorification of faithâbelief, or, if you will, âtrustâ or âconfidenceââwithout 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."
