Why Evolution is True is a blog written by Jerry Coyne, centered on evolution and biology but also dealing with diverse topics like politics, culture, and cats.
The last paragraph of this page, clearly from a Harry Potter book, was quoted by Christopher Hitchen’s in his essay collection Arguably. I’d like to use it, but I need the name of the Harry Potter book and the page number for the quote. Full reference, please. There are no prizes except the blessing of Ceiling Cat.
What this shows is that even Hermione can refute that argument.
From LOLtheists:
This first book isn’t really new, since it came out in 2012, but it’s new to me since I’ve just finished it.
It’s Unlearning Liberty: Campus Censorship the the End of American Debate by Greg Lukianoff. Lukianoff is president of FIRE (the Foundation for Individual Rights in Education), an estimable organization devoted to preserving freedom of expression on American college campuses.
The book is an eloquent argument for why campuses should be the places most dedicated to promoted and preserving free speech, but in fact often give their students and employees less free speech than they enjoy in public (FIRE deals largely with public universities). And it’s full of hair-raising stories, which would be funny if they didn’t result in punishment of students expressing their views.
One scary tale, for instance involves Keith Sampson, a student (and employee) at Indiana University-Purdue University in Indianapolis, who, in 2007, was found guilty of racial harrassment for simply reading a book whose cover offended his coworkers. The book was called Notre Dame versus the Klan, and its cover showed a photo of a Klan rally. The bizarre thing was that the book was “celebrating the defeat of the Klan in a 1924 street fight.” Nevertheless, Sampson was found guilty of “openly reading [a] book related to a historically and racially abhorrent subject.” Apparently that was the end of his career.
There are many similar stories of how universities, both public and private, try to curtail free speech for the merest of reasons, including protecting their administration from criticism. Lukianoff’s book is well worth reading, particularly if you’re connected with a university. It has are 37 reviews on Amazon; 35 of those give it the full five stars, and the other two four stars. That’s a good recommendation!

Brother Russell Blackford has a very nice new book with Udo Shucklenk that I’ve read in draft, 50 Great Myths about Atheism, which will be coming out on November 4 in the US. As you might expect from these authors, the book is meticulously researched and compulsively readable.
Rather than reprise those “myths,” here’s part of the contents that will give you an you an idea what they discuss. I particularly liked their section on the incompatibility of science and religion.
This book will give you lots of ammunition for arguing with those pesky theists and accommodationists.
In a post by Blackford at The Hellfire Club, he appends what he calls a “gentle rant” to a note about his books:
One thing that I notice in the blogosphere – and the social media generally – is how little of the daily discussion involves people’s responses to actual books and the information and arguments contained in them. And yet, some wonderful books are appearing month by month. Apart from 50 Great Myths About Atheism, you might want to check out the newest book by AC Grayling and the forthcoming book by Peter Boghossian, for example. And no, the ocean of wordage available for free on the internet is not usually a substitute for material that has been accepted by, and worked through with, reputable trade or academic publishers. (It should go without saying, I hope, that discussion of scandals and personalities is definitely not a good substitute for discussion of books and ideas.)
You tell them, Brother Blackford! I am so tired of atheist websites that spend their time squabbling about other atheists and whether they’re “pure” enough. (Yes, I know I’ve criticized atheists like Alain de Botton here, but it’s usually over ideas, not character.)
***
Finally, I’ve already recommended Peter Boghossian’s book, A Manual for Creating Atheists, which will be published by Pitchstone on November 1. As I said in my post:
I recommend it highly, as it’s quite different from other atheist books. Rather than going through the usual arguments against God and showing that religion is harmful and delusional, he takes these issues as givens and then tells the reader how to change other people’s minds, dispelling their faith. He tries to turn the reader into what he calls a “street epistemologist,” skilled at arguing against religious beliefs in a way that will actually work. His techniques are based on decades of experience in the classroom (he’s a philosopher who teaches courses in critical thinking and atheism at Portland state), in working with prisoners, and in one-on-one encounters with the faithful.
What I also like about the book is that he concentrates not on religion per se, but on the idea of faith as a failed epistemology. He thinks (and I agree) that our greatest leverage against religion is its reliance on “faith”—belief without good evidence—as a “way of knowing,” a way that is simply not justifiable to a rational person. One of our best weapons against religion is simply to ask its adherents, “How do you know that?” And so Boghossian’s strategies are concentrated on going after faith, and not letting yourself get distracted by issues like the so-called beneficial effect of religion on morality.
Before I begin, I emphasize again that I am not a philosopher, having taken just a few philosophy courses in college and done a fair bit of reading thereafter. What I present below are the lucubrations of a scientist grappling with theology.
UPDATE: I should have made clear that I’m talking about a theistic God here. If you posit a deistic God who doesn’t do anything, or some nebulous apophatic “ground of being” God, then of course you can’t disprove it. But there’s no reason to take it seriously, either. Those who posit an ethereal deity for which there’s no evidence are subject to Hitchen’s Dictum: “That which can be asserted without evidence can be dismissed without evidence.”

When discussing matters religious, the conversation often ends with a believer asserting: “You can’t disprove a negative.” What she means, of course, is this: “No matter what arguments you adduce against God, you’re unable to convince me—or anyone—that He doesn’t exist. That’s because you can’t prove that anything doesn’t exist.”
This argument is made by both believers and nonbelievers.
In an interview at Five Books, for instance, atheist Susan Jacoby said this:
“Of course an atheist can’t prove there isn’t a God, because you cannot prove a negative. The atheist basically says that based on everything I see around me, I don’t think so. Every rational thing I see and have learned about the world around me says there isn’t a God, but as far as proving there isn’t a God, no one can do that. Both the atheist and the agnostic say that.”
Biologist Ken Miller, an observant Catholic, said something similar on the BBC:
“The issue of God is an issue on which reasonable people may differ, but I certainly think that it’s an over-statement of our scientific knowledge and understanding to argue that science in general, or evolutionary biology in particular, proves in any way that there is no God.”
I don’t agree with either of these.
The “you can’t prove a negative” argument is wrong. You can prove a negative, which means disproving a positive (i.e., God exists)—if you construe the word “disprove” as meaning “showing that the existence of a phenomenon is so unlikely that one would have to be blinkered or perverse to still believe it.” And that is the case for God.
Scientists, of course, don’t use the word “prove”. We have greater or lesser degrees of confidence in phenomena. And when a phenomenon is supported by so much evidence that you’d have to be perverse to deny it (as Steve Gould put it), then we regard it as a fact, or “proven” in everyday jargon. I am immensely confident that the earth rotates on its axis, that a water molecule has on oxygen and two hydrogen atoms, and that we evolved from other creatures very different from modern humans. I regard those claims as “proven” in any meaningful sense, but to preserve the provisional nature of scientific truth, I avoid the word “proof” in both technical and popular presentations.
Now mathematicians can indeed “prove” things, for their domain is not the real world but the consequences of a series of axioms. Mathematicans can prove that, in Euclidean geometry, the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. That’s why mathematicians, but not natural scientists, consider things proven. “QED,” as they say: “which had to be demonstrated.” As Sean Carroll has said, there’s no conceivable world in which you can disprove mathematical propositions like the Pythagorean Theorem; no empirical observation that can refute it. (Let’s not talk about other geometries, okay? That’s beside the point.)
But we can “disprove” the existence of something, for all intents and purposes, by showing that the evidence that should be there if that something existed is missing. Victor Stenger has made this point repeatedly, and a famous earlier example is Carl Sagan’s argument against “The Dragon in My Garage” from The Demon-Haunted World. Read it (free at the link). It’s about someone who claims there’s a fire-breathing dragon in his garage, but the dragon is invisible, and its advocate keeps countering the skeptic’s observations of a lack of evidence with claims like ‘it’s invisible,” and “it floats, so you can’t detect footprints,” and “its fire is heatless, so you can’t feel it.”
Sagan’s point was, of course, that it doesn’t make sense to believe in things for which there’s no evidence, and that the “you can’t prove nonexistence” claim is fatuous when the evidence should be there. As he noted at the end of this parable:
Once again, the only sensible approach is tentatively to reject the dragon hypothesis, to be open to future physical data, and to wonder what the cause might be that so many apparently sane and sober people share the same strange delusion.
(Sagan was a lot more vociferous against religion than most people think!)
And so it is with other things. Can you disprove that I don’t have a heart? Of course you can: just do a CAT scan! Can you disprove that I am not married? For all practical purposes, yes: just try to find the records, ask people, or observe me. You won’t find any evidence. Can you disprove the notion that fairies live in my garden? Well, not absolutely, but if you never see one, and they have no effects, then you can provisionally conclude that they don’t exist.
God is like those fairies. Not only is he a supernatural being who’s supposed to exist, but, unlike fairies, a theistic God is supposed to have designated effects on the world. In particular, he’s supposed to be omnibenevolent, omnipotent, and omniscient. Some further believe that there is an afterlife in which one goes to either Heaven of Hell, that prayers are answered, that God had a divine son who was resurrected, and so on.
If these are true, there should be evidence for them. But there is none. In particular, this is what we find:
There is no evidence of divinity or miracles in the present world, and no palpable evidence of God-inspired miracles (prayers don’t heal amputees).
God, despite being omnipotent and desirous of our knowing him, has never appeared despite his manifest ability to do so. He could, for example, write “I am Yahweh; obey me” in the stars. This is the “hidden God”, the Deus absconditus. As philosopher Herman Philipse has noted, God should want each individual to know of his existence to create a reciprocal relationship.
Tests of intercessory prayer show no effect.
There is no good justification, assuming a benevolent and all-powerful God, for “natural evil,” the suffering of animals and innocent children due to diseases and natural disasters. Theologians’ attempts to explain why, for example, children get leukemia, why ten million civilians met their deaths at the hands of the Nazis, and why thousands are killed by tsunamis, are laughable, and not remotely convincing to anyone who hasn’t already bought into religious delusion.
Earlier “evidence” for divinity has been dispelled (creation, Adam and Eve, Great Flood, etc.)
A benevolent God would not kill off humanity in 5 billion years. Nor would a benevolent and powerful God use evolution or natural selection to create modern life and humans. That just doesn’t make sense, though theologians concoct amusing arguments not only why evolution makes sense, but why it should be God’s preferred way to bring species into being.
There is no explanation for why a benevolent God would allow more than 99% of the species he wanted to exist to subsequently go extinct without issue.
Most of the universe inhospitable to life, and nothing lives there. Why this largesse of uninhabitable space if God created Earth for humans? Even if life exists elsewhere, it can’t be common, and the trillions of uninhabited stars serve no purpose.
In the case of God, then, the absence of evidence is indeed evidence for His absence. We can provisionally but confidently say that there’s no evidence for a God. and therefore reject the notion that He exists. (This could be revised, of course, and in earlier posts I’ve given some possible evidence that would convince me of divine beings.)
Needless to say, all the above observations make sense—indeed, are expected—if God doesn’t exist.

Alert reader Mark called my attention to a comic strip called “Ten Cats,” which was new to me. After reading a few strips, I was taken. The artist is Graham Harrop, whose homepage gives the strip’s premise:
About TEN CATS:
Ten abandoned cats live in an old warehouse where they are looked after by a young girl named Annie. Unbeknownst to her, the warehouse contains a boardroom on the very top floor, where the moggies conduct the world’s business through the eyes of a cat.
The first below strip is today’s, and I’ve included a couple others as well:
This year “Ten Cats” won the Reuben Prize for “Best Online Comic: Short Form”
