Does evolution need a revolution?
I’m a bit late on this one, but the Albatross has kept me occupied. This post will be of interest mainly to science buffs, particularly those who already know a bit about evolution. But I’ll weigh in anyway, for, like an egg-eating snake expelling the shell, I had to get this out.
On October 9, the journal Nature published a longish comment by two groups of investigators called “Does evolutionary theory need a rethink?“. (Reference below; I believe the pdf is free. If not, you can get one by judicious inquiry.) It’s a “Point/Counterpoint” in which one group of evolutionists (whose part is called “Yes, urgently,”), suggests that modern evolutionary theory needs a rethink, and will be replaced by something quite different, while the other group (“No, all is well”) maintains that the “revolutionary” discoveries fit comfortably within the existing evolutionary paradigm, so no drastic overhaul is needed.
I read the “Yes, urgently” part first and decided to respond here without having read the other part, as I wanted to critique their views without being influenced by the “No, all is well” side.
Let me say first that I’m a bit puzzled by the continual appearance of these “Does evolution need a revolution?” pieces. If our field really was undergoing a revolution, we wouldn’t have to debate it. I doubt, for instance, that when there was a genuine paradigm shift in physics—from classical to quantum mechanics—we saw many physicists writing “Does physics need a rethink?” articles. The answer was obviously “yes.”
But even among those who see a paradigm shift in evolution, there’s nobody who sees anything like a complete overturning of our worldview, as happened when quantum mechanics appeared as a deeper and weirder supplement to classical mechanics. Although I haven’t read the “all is well” side, I agree with their conclusion as expressed in the title, and would probably agree with their arguments, which I’ll read after I write this. For the “revolutionary” phenomena touted by the “yes, urgently” side are either not new, fit comfortably within the modern view of evolution, are limited in scope, or, even if fairly frequent, wouldn’t cause a paradigm shift. By paradigm shift, I mean the view of evolution as gradual, based on variation in DNA sequences that change by either selection or genetic drift (or a few rarer processes), often propelled by natural selection, and producing branches—new species—that yield reproductively isolated populations that cannot interbreed (that’s what species are).
It’s also telling that nearly all the authors calling for an “urgent rethink” of evolutionary theory are those who have published or proposed the “revolutionary” ideas that motivate their views. And they severely overrate the nature of the scientific discussion going on:
This is no storm in an academic tearoom, it is a struggle for the very soul of the discipline.
“Struggle for the soul of our discipline”? That seems a bit dramatic and self-aggrandizing, and is simply untrue. There is no such “struggle” going on, except, perhaps, in the minds of those who feel that their work is not sufficiently appreciated or advertised.
That aside, let me discuss briefly the new phenomena that, the “yes” authors say, call for a new paradigm, an overthrow of what they call “standard evolutionary theory” (SET). There are four, which I’ll take in order:
1. The evolution of development (“evo devo”). The “yessers” claim that developmental biology was never properly incorporated into SET, and would change it drastically were this to happen. They further argue that evo devo has shown that some developmental pathways are more likely to evolve than others:
In our view, this concept — developmental bias — helps to explain how organisms adapt to their environments and diversify into many different species. For example, cichlid fishes in Lake Malawi are more closely related to other cichlids in Lake Malawi than to those in Lake Tanganyika, but species in both lakes have strikingly similar body shapes. In each case, some fish have large fleshy lips, others protrud- ing foreheads, and still others short, robust lower jaws.
SET explains such parallels as convergent evolution: similar environmental conditions select for random genetic variation with equivalent results. This account requires extraordinary coincidence to explain the multiple parallel forms that evolved independently in each lake. A more succinct hypothesis is that developmental bias and natural selection work together. Rather than selection being free to traverse across any physical possibility, it is guided along specific routes opened up by the processes of development.
I’m not sure why the authors feel that “developmental bias” is a more “succinct” hypothesis than convergent evolution. In fact, I see it the other way around. While some developmental pathways surely are easier to evolve than others, the remarkable plasticity of animals and plants under selection suggests that parallel selection may be a more important cause of convergent evolution. After all, icthyosaurs (reptiles), porpoises (mammals) and fish (fish) all evolved similar streamlined shapes independently. It’s more “succinct” to see this as groups of unrelated organisms responding to an environmental challenge (a watery milieu) by using different genes to produce similar shapes than by invoking similar developmental channels. After all, fish, reptiles, and mammals are only distantly related, and it seems unlikely that these shape changes reflect the constraints of development. (In fact, it would be hard to see them as anything other than selection having acted on different developmental pathways.)
And the same may be true for the cichlids in Lake Malawi and Lake Tanganyika. Why would one think that the repeated paths of evolution, which we also see in Australian marsupials versus distantly related placental mammals (both have “flying squirrels,” “moles,” and other similar forms) reflect similar developmental biases? There’s no evidence for developmental channelling here, but there’s evidence from many fronts (e.g., the remarkable plasticity of species under artificial selection) that animals have genetic variation to change into almost anything you want.
Evo devo is a fascinating field, and has come up with some stunning results: one is the discovery that developmental switches can be similar for traits even in distantly related organisms, like the Pax-6 gene controlling eye formation in flies and mammals. But that doesn’t argue for developmental channelling of entire phenotypes, for the eyes involve many different genes in mice and flies. There is still no good empirical evidence for “convergence” due to similarity of developmental pathways that are constrained.
2. Developmental plasticity. This is the notion that a single organism can change its appearance (phenotype) or physiology in different environments. Mammals may grow longer fur, or change their color from brown to white, when the weather gets colder and snowier; plants can grow toward the sun, or change their leaf shapes depending on how much sun they get; the two different claws of the lobster (crushing versus pinching) develop differently depending on which claw grabs an object first.
This is nothing new, for that plasticity is often adaptive and has evolved by natural selection. Those mammals who had genes for changing coat color in winter left more offspring (they were hidden from predators or prey), and those plants that could change their leaf shape or direction to catch the sun would photosynthesize more.
But the “revolution” advocates also propose another form of plasticity: an adaptive change in an organism is caused by phenotypes alone, with the genetic change lagging well behind:
If selection preserves genetic variants that respond effectively when conditions change, then adaptation largely occurs by accumulation of genetic variations that stabilize a trait after its first appearance. In other words, often it is the trait that comes first; genes that cement it follow, sometimes several generations later.
But all this really is is what we call “genetic assimilation”: that those traits that prove adaptive in a new environment, though perhaps a result of a malleable appearance, still have genes underlying them, and it is the accumulation of those genes that cause evolution.
Let me give an example. Suppose there are some Tiktaalik-like fishapods swimming near the shore. A few individuals venture out onto the land, as they show “behavioral plasticity” and are adventurous. It turns out that getting on the shore gives you all kinds of new food, particularly insects. They leave more offspring. Over time, the fishapod becomes a proto-amphibian. This is, in fact, the way that terrestrial tetrapods may have evolved.
But this is nothing new: in fact, it was suggested by Ernst Mayr in his famous 1963 book Animal Species and Evolution. Mayr said that many drastic changes in lifestyle may have begun with simple behavioral plasticity.
But the important thing to recognize is that behavioral change and its sequelae (like all the other adaptations for living on land) cannot evolve unless those changes have a genetic basis. What we see here is simply phenotypic (trait) variation that has some underlying genetic basis, and proves to be adaptive. The genetic changes accumulate, and eventually we get a big change in form, lifestyle, and so on. That’s simply conventional natural selection, not a revolution in SET. Further, we don’t know how often major changes in lifestyle happen this way. But whatever the case, this is not a paradigm shift.
There are other theories that the changes in phenotype are adaptive but have nothing to do with genetic variation, and the genes simply come along later to somehow “stabilize” the phenotype. This isn’t likely because it’s not obvious how lifestyle or form changes could evolve in such a way, since the initial changes would be lack any genetic underpinning. There’s one possible case involving loss of eyes in cave fish, but until that phenomenon is shown to be frequent, we can’t use it to tout a “revolution.”
3. “Nongenetic” forms of evolution. If evolution really weren’t based on heritable and permanent changes in DNA sequence, that would be surprising, and at least a major change in perspective. The “revolution” proponents argue that this does happen in two ways.
First, there is cultural evolution: stuff is passed on not by genes, but by learning. This, of course, is nothing new: Dawkins wrote about memes—units of cultural inheritance—way back in 1976, drawing a parallel between genetic and cultural evolution. But that was a parallel, and one that I don’t find terribly enlightening. But cultural inheritance is of course important in some species, including all animals that teach their young. The authors give some examples:
In addition, extra-genetic inheritance includes socially transmitted behaviour in animals, such as nut cracking in chimpanzees or the migratory patterns of reef fishes.
So what’s new? Yes, we can model how this works, but learning it itself an evolved ability, and modeling social evolution will involve things beyond the purview of evolutionary theory. Cultural evolution is not genetic evolution, and hence not part of the SET, which rests on changes in genes. Cultural evolution is important, but it’s no more part of SET than is the “evolution” of changes in automobile style over the years.
The “revolution” authors also include epigenetics as an important component of nongenetic inheritance, one that will revolutionize evolution. By “epigenetics,” they mean environmentally induced changes in the DNA (e.g., methylation of DNA bases) that somehow become coded in the DNA, so that the environment by itself can change the genome and eventually produce adaptive evolution.
While adaptive methylation has been known for a while (male versus female DNA in zygotes is often differentially methylated, and in ways that favor one parent’s genes), all of this adaptive methylation depends on changes in the DNA code itself—changes that tell the DNA to let itself be methylated. That’s different from the new proposal, which claims that such changes aren’t initially coded in the genes, but directly produced by the environment. (This is “Lamarckian” evolution for those of you who know what that means.)
The problem with this is that such cases of environmental changes in DNA are always temporary, for they’re not coded in the DNA and thus cannot persist forever. And if they’re temporary, they cannot cause long-term adaptive evolution. In fact, there is not a single known case of any new organismal trait based on environmentally-induced change of DNA that has persisted for more than a few generations. And we know of no adaptive change based on such a process. In contrast, there are lots of cases of evolutionary changes and adaptations based on heritable, non-environmentally-induced changes in DNA—that is, “conventional” changes caused by mutations. In view of this paucity of evidence for environmentally-caused epigenetic change as an evolutionary factor, why are the authors calling for us to overturn SET?
4. “Niche construction.” This is a recent buzzword in evolutionary biology that is an interesting notion, and one that certainly holds true in many cases of evolution. It is the idea that the organism’s own activities modify its environment in a way that changes the direction of natural selection acting on that organism. The classic example is the beaver. These rodents have evolved to build dams and live in those dams, and thereby have modified their environment in a way that affects their subsequent evolution. Due to its own evolution, the beaver now lives in a lake it made itself, and lives inside a house of sticks that it also built. That must surely influence its future evolution, and which mutations could be adaptive (ones promoting better swimming and tree-felling, for instance). Ditto for social insects, who now live in complex burrows (built by them, of course) that must surely affect their later evolution.
While this idea is getting new attention, and deservedly so, it doesn’t call for a revolution in SET. First of all, it’s not particularly new. The idea of “gene-culture” coevolution has been around a long time. One example is pastoralism, in which humans changed their environment by keeping domestic animals that give milk. And that has changed our evolution, for cultures that are pastoral have undergone evolution involving the use of lactose. Genes that break lactose down into digestible components are usually inactivated after weaning in humans, who, over most of our history, didn’t have a source of milk after they stopped suckling. That’s why many of us are “lactose intolerant.” When we suddenly got a rich source of nutrition from our sheep and cows, pastoral cultures evolved so that the genes metabolizing lactose weren’t inactivated,but were turned on for life. (Individuals with genes allowing them to digest milk had up to 10% more offspring on average than intolerant individuals!) Thus, our own culture affected our subsequent evolution. This did not cause us to dismantle SET; rather, it was an interesting sidelight on how culture itself caused genetic change.
Second, we don’t know how pervasive this process is. That is, while many organisms do affect their environments, we don’t know how often that environmental change feeds back to the organism to cause additional evolution. In some cases it probably doesn’t: fish adapt to an unchanging fluid medium, the coat color of polar bears cannot affect their environment of ice or snow, and the hooves of the chamois don’t affect the granitic structure of the Swiss Alps. So how often “niche construction” is important is an open question, albeit an interesting one. But I don’t see it overthrowing SET, for it’s simply a novel way that the environment can change and affect organismal evolution.
That is not to disparage this phenomenon—or any of these phenomena. Niche construction seems more likely to be important than “genes follow phenotype” plasticity, or than adaptive epigenetic evolution, of which we have not a single example. All these ideas deserve empirical study. But none call for a new paradigm.
Now I can read what the “conservatives” (Wray, Hoekstra, Futuyma, Mackay, Lenski, Strassmann, and Schluter) have to say.

The National Academy honors Ernst Mayr
by Greg Mayer
Ernst Mayr (1904-2005) was one of the greatest biologists of the 20th century, an architect of the “Modern Synthesis” of evolutionary biology which harmonized Mendelism and Darwinism and showed that the
phenomena of paleontology, systematics, and genetics formed a mutually consistent and coherent whole. Mayr in particular identified and explicated the importance of the discontinuities in the diversity of life we identify by the name species, characterized the nature of species through the biological species concept, and forcefully argued for the importance of geographic isolation as a key ingredient in the origin of species. Although some of his greatest contributions were yet to come, he was elected to the National Academy of Sciences in 1954.
The Academy honors its members who have died in its Biographical Memoirs, and last week they released the Memoir for “Uncle Ernst” (as he was affectionately known to graduate students at the Museum of Comparative Zoology). The Memoir, by Walter J. Bock, perhaps Mayr’s most distinguished graduate student, was previously published in 2006 in the equivalent series of the Royal Society, the Biographical Memoirs of Fellows of the Royal Society. It consists of a short, fact-filled biography, highlighting both Mayr’s life and scientific contributions, a chronological list of his various professional appointments and numerous awards and honors, and a selected bibliography of his most important books and papers. The Academy has made the Memoir available as a free pdf (as has the Royal Society), and it serves as a nice introduction to Mayr and his work. (There is an amusing typo on p. 10, uncorrected from the Royal Society version: referring to Mayr’s dissatisfaction with certain aspects of his positions in New York, Bock writes “…he became more and more reckless in his situation in New York City”; “restless” is obviously intended– Mayr soon left for the Museum of Comparative Zoology at Harvard.)
The first full biography of Mayr (the manuscript of which was available to Bock) appeared in 2008: Ornithology, Evolution, and Philosophy: The Life and Science of Ernst Mayr 1904–2005, by Juergen Haffer. Haffer, who passed away in 2010, was a field geologist by profession, but also an accomplished avocational biologist, well known for his monograph on speciation in Amazonian birds. He was a friend of Mayr’s, and his biography includes much information provided by Mayr himself over many years of interviews and discussions. The biography is, in fact, more akin to a primary document, and will be a rich resource for future biographers.
Jerry has written two important papers on Mayr, one being Mayr’s obituary for Science. Written under a tight time deadline, I recall worrying with Jerry about getting certain details right: who did send Mayr on his momentous, life-changing expedition to the South Pacific in 1928? Looking back at our correspondence, I see that I suggested that Walter Bock would know, but there was no time to make inquiries. It turns out that what Jerry eventually wrote is about right, that the full answer is rather complex, and Walter Bock did know. And by reading the memoirs — and even more so Haffer’s book — everyone can know.

Readers’ wildlife photos
Marooned in the wilds of rural Canada, reader Diana MacPherson nevertheless takes great wildlife photos of the creatures in her yard. Here are a sparrow (Passer domesticus) and some chipmunks (Tamias striatus). Sadly, I’ve lost the notes, and am no good at anthropomorphizing, but remember that the sparrow displaced the chipmunk from its seeds.
I remember Diana said that this one looked as if it got a bitter taste from licking the deck:
And from Stephen Barnard of Idaho, “A trumpeter swan (and some mallards)”. The swan is Cygnus buccinator; the mallard is Anas platyrhynchos, which you should know by now.
The two best soul songs ever
As promised, here is Professor CC’s choice of the two best soul songs ever. This was a hard one, as my list of favorites is long, and of course many will disagree with these choices (you may list your TWO favorirtes—no more—in the comments). Both of these were written, at least in part, by Smokey Robinson (a musical genius), both were recorded on the Motown label, and both are ballads about lost love.
The first one is almost a no-brainer. “Ooo Baby Baby” has been covered many times, and is a perennial favorite of anyone with taste. It is of course by the immortal (well, Smokey’s still alive) Smokey Robinson and the Miracles, released on the Motown label in 1965. It was written by Robinson and Pete Moore, and the instrumentals are by the Funk Brothers. Note the instantly recognizable beginning: a Funk Brothers speciality.
There’s not much to say except that this is the quintessential Motown ballad, and it’s a crime that it reached only #4 on the Billboard R&B charts and #16 on the Billboard Hot 100. This is definitely a number one hit. Here’s a lip-synched version, the best I could find:
The second is a lesser-known but still famous hit, first recorded by the Temptations. “Since I Lost My Baby” was released in June, 1965, six months after “Ooo Baby Baby”. It was co-written by Smokey Robinson and Warren Moore, and the lead singer is David Ruffin, whose brother died last week. (David Ruffin died in 1991 at the age of only 50.) It was about as popular as the first song, reaching #4 on the R&B charts and #17 on the Hot 100 chart. When I was a part-time DJ at my college radio station, I’d play this as often as possible (my sign-off song was the Temptations’ “I’m Losing You.”
“Since I Lost my Baby” is a simple song, contrasting the singer’s pain with the good things he sees around him. The line “There’s plenty of work and the bosses are paying” always gets me.
If you want to see alternative versions of these, there’s a famous “Ooo Baby Baby” by Linda Ronstadt and a wonderful medley of “Sara Smile” and this song by Darryl Hall and Smokey Robinson, performed on the underappreciated “Live from Darryl’s House” show. Darryl appears to surprise Smokey by doing the Motown song (the surprise starts at 4:29), and Robinson at first appears reluctant to sing. His song requires a falsetto that he thought he no longer had (he did fine).
YouTube also has a five-minute mini-documentary, interviewing Hall, Ruffin and others about “Since I Lost My Baby” and other Temptation hits; it’s well worth a listen.
Monday: Hili dialogue
It’s Monday again, but in the U.S. we have Thanksgiving on Thursday, and either the day before or after that, the galley proofs of The Albatross arrive, so I will a. see the book in near-final form, and b. have more work to do. Meanwhile in Dobrzyn, today’s Hili dialogue is one of the rare ones with a title:
Pavlov’s catHili: When I hear the sound of cutlery I go to the kitchen.A: And so does Cyrus.Hili: Interesting, how did you spoil him like that?

Reza Aslan and Karen Armstrong are everywhere, and it’s not pretty
I can’t get enthused about discussing Karen Armstrong and Reza Aslan any longer. They’re both in the media spotlight because they coddle religion in an age when it’s eroding but some people desperately cling to faith; they’re both religious apologists, refusing to pin any malfeasance on faith; and they both say the same thing in interview after interview. So just let me drop a few quotes from Armstrong and move on. I’ll deal with Aslan tomorrow—if I feel up to it.
Karen Armstrong was interviewed in Salon (also known as “The Journal of Religious Osculation”), and, surprisingly, was handed a few tough questions, which she ducked.
She begins by saying that the distinction between religion and politics is a modern innovation, and continues by claiming that nothing, including suicide bombing, is solely or even largely motivated by religion (she cites discredited statistics by Robert Pape, misspelled in the article as “Robert Tate”). She argues further that humans need mythologies (i.e., religion) to give purpose and meaning to our lives:
Let’s try a different analogy: Perhaps our search for narrative and meaning is a bit like a fire. It can go out of control and burn people pretty badly. Seeing this destruction, some people say we should just put out the fire whenever we can. There are others who argue that the fire will always be there, that it has benefits, and that we need to work with it to the best of our abilities. And you’re sort of in the latter camp, yes?
I would say so … If we lack meaning, if we fail to find meaning in our lives, we could fall very easily into despair. One of the forensic psychiatrists who have interviewed about 500 people involved in the 9/11 atrocity, and those lone-wolves like the Boston Marathon people, has found that one of the principal causes for their turning to these actions was a sense of lack of meaning; a sense of meaningless and purposelessness and hopelessness in their lives. I think lack of meaning is a dangerous thing in society.
Armstrong apparently feels that religion is an essential source of meaning for modern people. And a lack of meaning, says Armstrong, plays a huge role in terrorism, for terrorists aren’t really motivated by religion, but by nihilism (WHAT?):
There’s been a very strong void in modern culture, despite our magnificent achievements. We’ve seen the nihilism of the suicide bomber, for example. A sense of going into a void.
The void clearly represents a failure to appreciate Armstrong’s notion of God as Love, Meaning, and the Ineffable Ground of Being, whereof we cannot speak.
But it seems to me that many of these terrorists clearly do embrace the “mythologies” that Armstrong sees as necessary for our world. They aren’t nihilists in any conventional sense of the word. She grudgingly admits that religion may be in the mix of terrorists’ motives, but, in the end, it’s really other stuff:
In fact, all our motivation is always mixed. As a young nun, I spent years trying to do everything purely for God, and it’s just not possible. Our self-interest and other motivations constantly flood our most idealistic efforts. So, yes, terrorism is always about power — wanting to get power, or destroy the current power-holders, or pull down the edifices of power which they feel to be oppressive or corruptive in some way.
Of course, she doesn’t consider that “power” might be “the power to impose your faith on others,” as in ISIS’s Caliphate and the actions of other Islamic extremists. She then goes on to blame Muslim terrorism completely on the West, though she neglects to discuss Muslim-on-Muslim terrorism, by far the most common form. Somehow, I suppose, she’d also pin that on colonialism. But the worst thing she says is this:
When you hear, for example, Sam Harris and Bill Maher recently arguing that there’s something inherently violent about Islam — Sam Harris said something like “Islam is the motherlode of bad ideas” — when you hear something like that, how do you respond?
It fills me with despair, because this is the sort of talk that led to the concentration camps in Europe. This is the kind of thing people were saying about Jews in the 1930s and ’40s in Europe.
This is how I got into this, not because I’m dying to apologize, as you say, for religion, or because I’m filled with love and sympathy and kindness for all beings including Muslims — no. I’m filled with a sense of dread. We pride ourselves so much on our fairness and our toleration, and yet we’ve been guilty of great wrongs. Germany was one of the most cultivated countries in Europe; it was one of the leading players in the Enlightenment, and yet we discovered that a concentration camp can exist within the same vicinity as a university.
There has always been this hard edge in modernity. John Locke, apostle of toleration, said the liberal state could under no circumstances tolerate the presence of either Catholics or Muslims. Locke also said that a master had absolute and despotical power over a slave, which included the right to kill him at any time.
That was the attitude that we British and French colonists took to the colonies, that these people didn’t have the same rights as us. I hear that same disdain in Sam Harris, and it fills me with a sense of dread and despair.
This shows two things. First, Armstrong doesn’t want any criticism of religion, for religion is inherently good as a concept, and what bad things seem to spring from it come simply from misinterpreting true religion. Criticize it at your peril, for you’re being a Nazi when you do. (How lovely of Armstrong to play the Hitler card against critics of Islam!)
Second, she can’t distinguish between criticism of religious tenets and racism or bigotry. The Nazis were manifestly not saying that Jews should be killed because their beliefs were unsupported (though their supposed role as Christ-killers was certainly in the mix), but because they were Jews, and Jews were rats who deserved extermination. Further, the Nazis weren’t saying “Judaism is the motherlode of bad ideas.” They were saying “Jews are bad and should be killed.” You don’t hear Sam Harris or Bill Maher saying that Muslims should be exterminated. They’re saying that bad ideas should be attacked. Perhaps Armstrong thinks that there are no bad ideas in religion, but then she’d be blinkered—as she is.
And here’s a lovely exchange:
. . . (Armstrong:) Fundamentalism represents a rebellion against modernity, and one of the hallmarks of modernity has been the liberation of women. There’s nothing in the Quran to justify either the veiling or the seclusion of women. The Quran gave women rights of inheritance and divorce, legal rights we didn’t have in the West until the 19th century.
That’s what I feel about the treatment of women in Saudi Arabia. It’s iniquitous, and it’s certainly not Quranic.
She should have a look at the hadith as well, for that’s part of Muslim tradition, and adds some iniquity. But at least she decries the treatment of women in Saudi Arabia. By Gad, she’d better! However, she emphasizes that this misogyny is not based on authentic Islam. That leads the interviewer to ask a good question:
Where do you, as someone outside of a tradition, get the authority to say what is or isn’t Quranic?
I talk to imams and Muslims who are in the traditions.
What? Doesn’t she know that there is more than one tradition in Islam, and some of them are iniquitous? There is, for example the Quranic tradition that apostates deserve death. Doesn’t she know, too, that there’s more to religion than “tradition”—there is what the imams say now, how it’s based on the Qur’an, and how people follow their dictates? Her assumption that tradition is everything in determining religious dogma (which is wrong), and that any Islamic perfidy isn’t “traditional,” are just cheap ways of ignoring the bad religious dogma.
In the end, she simply admits that she’s cherry-picking scripture:
I think it’s easy to say, “Well the text isn’t binding” when you see something in there that you don’t like. But when you see something in the text that you do want to uphold, it’s tempting to go, “Oh, look, it’s in the text.”
Oh, it is. We do it with all our foundation texts — you’re always arguing about the Constitution, for example. It’s what we do. Previously, before the modern period, the Quran was never read in isolation. It was always read from the viewpoint of a long tradition of complicated, medieval exegesis which actually reined in simplistic interpretation. That doesn’t apply to these freelancers who read “Islam for Dummies”.
“It’s what we do.” That is, we can ignore the bad parts of scripture and pretend that Christianity, Judaism, and Islam are based on just the good parts. And I doubt that many members of ISIS or Hamas have read “Islam for Dummies”. They have, however, read or heard the Qur’an.
Despite her constant self-promotion as an arbiter of compassion, Karen Armstrong is dangerous. She’s dangerous because her blanket of tedious verbiage hides the truth that she wants us to completely ignore the dangers of religious dogma. She thereby enables it. And it appears that for her, there is no harmful dogma that can be pinned on religion itself: it’s all about politics, oppression, or nihilism.
Well, tell that to the Catholics who prevent women from getting abortions, couples from getting divorces, and who demonize gays and inform Africans that condoms won’t prevent AIDS. Tell that to the Muslims who kill other Muslims because they think the heads of the faith should be genetic descendants of Muhammad, and who mutilate the genitals of their daughters because the imams insist it’s a sign of purity. Tell that to the Hindus and Muslims who butchered each other by the millions in 1947 even though they lived cheek by jowl and were similar in most ways except for their faith.
It’s a curious fact that people like Armstrong, Aslan, and Pape can so easily see how politics can motivate people to do bad things, but yet insist that religion cannot. I wonder what observations would really convince them that people’s religious (as well as political) beliefs can make them do harm. Can they tell us? The jihadis’ repeated insistence on religious motivation is apparently misleading, for they don’t know their own minds. Armstrong and Aslan know better.
Professor Ceiling Cat on video this afternoon
I’m supposed to appear today on the streamed podcast (vodcast?) Road to Reason: A Skeptic’s Guide to the 21st Century, an hourlong show broadcast on Fairfax County Public Television, streamed live on the Internet, and subsequently archived. (I’ll be Skyping in.) The live broadcast is at 3-4 pm EST in the US (2-3 pm Chicago time, 8-9 pm London time).
If you want to watch live, you can, I think, see it here, but you have to register for Usestream. But that’s dead easy, requiring you to furnish just an email address a user name, and a password. Then, I guess you can press “go live”. Here are the buttons and links to look for at the upper left of the page:
And her are the show’s regular hosts:
Rick Wingrove: Capital Area Representative for American Atheists.
Rob Penzcak: Physician turned writer.
David Tamayo: President and Founder of Hispanic American Freethinkers.
Larry Mendoza: Director for Educational Outreach, Beltway Atheists, Inc.
Liz Green, Secular Humanist
So far I’ve been communicating with Rob Penzcak, who sent me a 20-page list of questions (!) he thought of asking; this guy does his homework. (There may be another host or two.) At any rate, we’ll cover evolution, creationism, and the science-vs.-faith aspect of my upcoming book, out in May of 2015.
I am showered, shaved, sweetened with all the perfumes of Arabia, and ready to go.
