"But some of our moral behaviors, if not sentiments, almost certainly evolved. Evidence for that comes from finding parallels between the behavior of our own species and that of our relatives."

"But the God hypothesis for morality and altruism has its own problems. It fails, for example, to specify exactly which moral judgments were instilled in people by God and which, if any, might rest on secular reason. It doesn’t explain why slavery, torture, and disdain for women and strangers were considered proper behaviors not too long ago, but are now seen as immoral. For if anything is true, God-given morality should remain constant over time and space. In contrast, if morality reflects a malleable social veneer on an evolutionary base, it should change as society changes. And it has."

"While our view of the world is filtered through our senses, evolution has, by and large, molded those senses to perceive the world accurately, for there’s a severe penalty to be paid for seeing things wrongly. That holds not only for the external environment, but also for the character of others. Without accurate perceptions, we couldn’t find food, avoid predators and other dangers, or form harmonious social groups. And following those perceptions is indeed the pursuit of “true beliefs”: beliefs based on evidence. Natural selection doesn’t mold true beliefs; it molds the sensory and neural apparatus that, in general, promotes the formation of true beliefs."

"It doesn’t trivialize morality to argue that it is based on evolution and secular reason."

"When one has a religious experience, what is “true” is only that one has had that experience, not that its contents convey anything about reality."

"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."

"Putting all this together, we see that religion is like Sagan’s invisible dragon. The missing evidence for any god is simply too glaring, and the special pleading too unconvincing, to make its existence anything more than a logical possibility. It’s reasonable to conclude, provisionally but confidently, that the absence of evidence for God is indeed evidence for his absence."

"Science’s results alone justify its usefulness, for it is, hands down, the single best way we’ve devised to understand the universe."

"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."

"In religion, faith is a virtue. In science, faith is a vice."

"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."

"Isn’t science, as some maintain, based on a “faith” that it’s good to pursue the truth? Hardly. The notion that knowledge is better than ignorance is not a quasi-religious faith, but a preference: we prefer to know the truth because accepting what’s false doesn’t give us useful answers about the universe."

"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."

"As the journalist Nick Cohen noted about accusations that atheism is like religion, “It’s not a charge I’d throw around if I were seeking to defend faith. When people say of dozens of political and cultural movements from monetarism to Marxism that their followers treat their cause ‘like a religion,’ they never mean it as a compliment. They mean that dumb obedience to higher authority and an obstinate attachment to dogma mark its adherents.”"

"Most religions, and certainly the Abrahamic ones, have three features that are foreign to science. The most important is religion’s linkage to moral codes that define and enforce proper behavior, behavior supposedly reflecting God’s will. The second is the widespread belief in eternal reward and punishment: the notion that after death not just your fate but everyone else’s depends on adherence to conduct mandated by your religion. And the third is the notion of absolute truth: that the nature of your god, and what it wants, is unchanging. While some believers see their ability to fathom God’s nature as limited, and don’t accept the notion of a heaven or hell, the certainty of religious dogma is ar more absolute and far less provisional than the pronouncements of science. This combination of certainty, morality, and universal punishment is toxic. It is what leads many believers not only to accept unenlightened views, like the disenfranchisement of women and gays, opposition to birth control, and intrusions into people’s private sex lives, but also to force those views on others, including their own children and society at large, and sometimes even to kill those who disagree."

"For good people to do evil doesn’t require only religion, or even any religion, but simply one of its key elements: belief without evidence—in other words, faith. And that kind of faith is seen not just in religion, but in any authoritarian ideology that puts dogma above truth and frowns on dissent."

"Science has a huge advantage over “other ways of knowing”: built-in methods of self-correction."

"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 universe—at 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 we’ll 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 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 orderliness of nature—the so-called set of natural laws—is not an assumption but an observation."

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

"The fact that both Jews and Christians ignore some of God’s or Jesus’s commands, but scrupulously obey others, is absolute proof that people pick and choose their morality not on the basis of its divine source, but because it comports with some innate morality that they derived from other sources."

"It takes a profound hypocrisy to try to reconcile for others things that you can’t reconcile for yourself."

"No reputable theologian, or rational believer for that matter, adheres strictly to Biblical morality. As everyone knows, believers pick and choose their morality from a smorgasbord of divine commands, both good and bad, in scripture. And doing that shows that you have a sense of right and wrong that doesn’t come from the Bible or God. Ergo, it comes from evolution and culture."

"Religion may be a quest for the truth, but it has no way of finding the truth, or verifying what it claims to find. Our knowledge of what God is like has not advanced one iota over the ideas of the 1500s. And insofar as theological interpretation has changed, it’s done so not as a result of faith’s quest for truth, but of pressure from science and secular morality. Really, can any theologian, philosopher, or scientist tell me anything about God now that we didn’t know 500 years ago? Then ask a scientist what we know now about science that we didn’t know in 1500."

"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."

"But this (a listing of illustrations of how the genome can change other than by mutations) doesn’t constitute a crisis—it’s a very interesting finding that shows that variation in a genome can arise by processes other than mutation of an organism’s own DNA. The disposition of that variation still must occur via either natural selection (it can be good or bad) or genetic drift (no effect on fitness). This hasn’t really changed the theory of evolution one iota, though it’s changed our view of where organisms can acquire new genes."

"Damn, but science is just a constant feed of cool new facts and theories. Theology doesn’t come close."

"I am SO tired of this trope. It may indeed be the case that we can’t justify a priori via philosophical lucubrations that we arrive at the truth about nature only by using the methods of science. My answer to that is increasingly becoming, “So bloody what?” The use of science is justified because it works, not because we can justify it philosophically. If we are interested in finding out what causes malaria, no amount of appeal to a deity, philosophical rumination, listening to music, reading novels, or waiting for a revelation will answer that question. We have to use scientific methods, which, of course, is how causes of disease are found."

"Why, exactly, are scientists supposed to accord “respect” to a bunch of ancient fables that are not only ludicrous on their face, but motivate so much opposition to science?"

"Theodicy is the Achilles Heel of faith. There is no reasonable answer to the problem of gratuitous evil (i.e., the slaughter of children or mass killings by natural phenomena like tsunamis), 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. (Special pleading like “we don’t know God’s mind” doesn’t wash, for the same people who say such things also claim to know that God is benevolent and omnipotent). 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."

"Faith is a padlock of the mind, and few keys can open it."
