Good Montreal Atheists

 
Yesterday we were part of a live podcast moderated by three Montreal Atheists; Jacon Fortin, Ryan Harkness, and Jeffrey Jones. They talked about dicks and how to be one. Phil Plait would not have been pleased!

You can hear the podcast on their blog The Good Atheist [The Good Atheist Podcast: Episode 107].

The Sound of Science

 
This is cute, but it's also deeply troubling.

I really don't like Darwin worship. It's true that I think he was the greatest scientist who ever lived, but science has moved on since 1859. Modern scientists respect, but do not worship, the past.

There are a couple of other problems with the lyrics. I'm confused about the reference to "theory" as some kind of "abstraction" and I don't like the implication that we go back and read Darwin to refresh our memory about modern evolutionary theory.

I also don't like the simplistic explanation of how real science is done. It's a common myth that publishing a peer-reviewed paper is the only way to do science. There are two things wrong with this mythology. First are the obvious exceptions, Origin of Species being one of them. Second, there's plenty of bad science papers in the peer-reviewed literature. Publishing in the peer-reviewed literature is neither necessary, nor sufficient, as a measure of good science.

Montréal

 
I'll be in Montréal, Québec, Canada this weekend attending the Atheist Alliance International (AAI) convention, Atheists Without Borders (Atheés Sans Frontières).

I'm arriving around 6pm on Thursday and leaving Sunday afternoon. Anyone else going? Contact me by email so we can get together. Maybe food and beverages on Thursday evening? (My address is at the top of the left sidebar.)

Most of Montréal is on a large island in the middle of the St. Lawrence river. The site was occupied by the St. Lawrence Iroquois when the first Europeans arrived in the 1530's. They had established a large village called Hochelaga but this village was largely deserted by the time Europeans constructed the first settlement in 1611.1 My ancestor, Barthélemy Montarras, was a soldier in the Compagnie Froment, Le régiment de Carignan, based in Montréal around 1665.

The dominant feature of the city is Mont Royal (Mount Royal) a group of hills right in the middle of Montréal island. The hills were first scaled by Jacques Cartier in 1535. A wooden cross was erected in 1635. The giant illuminated cross that we see today was built in 1924.

Montréal has several half-decent universities but, more importantly, it has many excellent bistros and cafés. I hope to try several of them this weekend. There are some special dishes that you just can't get in Toronto—or if you can get them, they're not nearly as good. It's sad that some of my friends won't be able to sample the smoked meat or the poutine due to restrictions imposed by their doctor.



1. Quebec City was founded in 1608. Santa Fe, New Mexico in 1608 and the Mayflower arrived in Massachusetts in 1620.

Ever Wonder What Teachers Make?

Stephen Meyer Explains Modern Evolution

 
The video below shows Stephen Meyer explaining evolution to the people who attended the Four Nails in Darwin's Coffin event at Southern Medodist University.

I'm posting this for my students in the class I teach on scientific controversies. One of the fundamental principles of any debate is to define your terms in a way that's intellectually honest and consistent. In the case of the creation/evolution debate, if there's actually a scientific controversy (there isn't) then everyone should be using the best scientific definition of evolution.

In his latest book, Signature in the Cell, Meyer refers to "modern" evolutionary theory as "neo-Darwinism." He never defines it but it's clear that he thinks of neo-Darwinism as the idea that mutation and natural selection are all there is to evolution. It's clear that Stephen Meyer has not read any modern textbook on evolution.

Watch the video and see how Meyer explains evolution to his mostly scientifically illiterate audience. At 6 minutes he says, "What we want to address tonight is the question of whether or not the principle neo-Darwinian mechanism of mutation and selection is sufficient to produce the forms of life that we see."

The scientific answer to this question is "no," mutation and selection are not sufficient. You also need random genetic drift, speciation, and geological events such as meteor impacts and ice ages in order to account for life as we see it today. (That's not an exclusive list, see Macroevolution.)

Meyer, and the next speaker, Richard Sternberg, are criticizing the ability of natural selection to explain the evolution of new forms in just a few million years. Most of their criticisms would apply to ALL explanations of evolution and not just those that rely only on mutation and natural selection but their arguments are much weakened by their lack of knowledge of modern evolutionary theory. It seems easy for them to knock down the strawman version of evolution that they don't believe in.

If there's a genuine scientific controversy here, you'll never learn about it by listening to these IDiots. However, it's worth noting that the quality of debate in the evolution/creation wars has improved considerably over the past thirty years. It used to be the case that any college student could instantly recognize the main flaws in the creationist position. Today, the average college biology student would have a great deal of difficulty debating Stephen Meyer, Richard Sternberg, Michael Behe, or Doug Axe. (Jonathan Wells? Not so much.) In part, that's because the average college student doesn't know enough about evolution. We aren't doing a very good job of teaching evolution.



Martin Rees Explains Accommodationism

 
Martin Rees is the President of the Royal Society in the UK. This is a position of enormous influence. When Rees speaks you can assume that he is representing the position of the Royal Society, or at least it's leaders.

Martin Rees was recently interviewed by The Independent [Martin Rees: 'We shouldn't attach any weight to what Hawking says about god'].
He is equally scathing about Hawking's more recent comments about there being no need for God in order to explain creation. "Stephen Hawking is a remarkable person whom I've know for 40 years and for that reason any oracular statement he makes gets exaggerated publicity. I know Stephen Hawking well enough to know that he has read very little philosophy and even less theology, so I don't think we should attach any weight to his views on this topic," he said.

Unlike many of the Fellows of the Royal Society he has presided over in the past five years, Lord Rees is not a militant atheist who goes out of his way to insult people of belief – Richard Dawkins once called him "a compliant quisling" for his tolerance of religion.

"I would support peaceful co-existence between religion and science because they concern different domains," Lord Rees said. "Anyone who takes theology seriously knows that it's not a matter of using it to explain things that scientists are mystified by."

His next popular science book is about these things that science still cannot explain, such as the origin of life on Earth and the scientific nature of human consciousness. This, he insisted, is what science is really about, and why it has the power to touch everyone of every culture.
I don't have time for a detailed explanation of this particular accommodationist position so I'll just note a few points.
  • Hawking said there's no need for God but his views can be dismissed because (unlike Martin Rees?) he's not an expert on philosophy and theology.

  • Rees does not go out of his way to insult people of belief. Good for him. Neither do lots of atheists, including Stephen Hawking. What's the point? Sounds to me like Dawkins might have been correct.

  • Did Martin Rees just go out of his way to insult atheists like Stephen Hawking? I guess atheists don't deserve the same kid-gloves treatment that we owe to theists.

  • Religion and science concern different domains. So they do. Religion is firmly planted in the domain of mythology and superstition. What does that prove?

  • Martin Rees is an astronomer. He's writing a book about the origin of life and human consciousness. I wonder if we should bother paying any attention to this book since he's not an expert in biology?

Sophisticated Theology

 
From Married to the Sea.



[Hat Tip: Friendly Atheist.]

A Challenge to Theists and their Accommodationist Supporters

Jerry Coyne is to be congratulated for reading The Huffington Post. I can't be bothered, but I'm happy when he finds something interesting [CfI declares war on atheists].

His latest discovery is a childish rant by John Shook, Director of Education and Senior Research Fellow, Center for Inquiry. Like Jerry Coyne, I am terrbily disappointed in the American branch of the Center for Inquiry. If the kind of nonsence they're spreading ever begins to contaminate the Centre for Inquiry in Canada then I will quite the organization. (I am currently a CFI Canada Advisory Fellow.)

Here's what Shook says in his HuffPo article [For Atheists and Believers, Ignorance Is No Excuse].
Atheists are getting a reputation for being a bunch of know-nothings. They know nothing of God, and not much more about religion, and they seem proud of their ignorance.

This reputation is a little unfair, yet when they profess how they can't comprehend God, atheists really mean it. To listen to the loudest atheists, you can hear the bewilderment. And they just can't believe how a thing like religion could appeal to any intelligent person. The mythological story told by atheists recounts how religion arose through vast ignorance and perversity. A plague upon humanity, really, infecting the dimwitted or foolish with viral memes about spirits and gods. If there's no arguing with irrational people or dumb viruses, what's to be done?

Astonished that intellectual defenses of religion are still maintained, many prominent atheists disparage theology. They either dismiss the subject as irrelevant, or, if they do bother to acknowledge it, slim refutations of outdated arguments for a medieval God seem enough. Atheists cheer on such bold leadership, but what is really being learned? Challenging religion's immunity from criticism is one thing; perpetuating contempt for religion's intellectual side is another. Too many followers only mimic the contempt, forgetting that you won't effectively criticize what you would not understand. The "know-nothing" wing of the so-called New Atheism really lives up to that label. Nonbelievers reveling in their ignorance are an embarrassing betrayal of the freethought legacy.
The question before us is whether there is a God or there isn't. So far, I have not been convinced by any argument in favor of supernatural beings. Every single argument that I've encountered seems flawed. Many of them are stupid and nonsensical.

I am not a "know-nothing." I've made a big effort to learn the latest arguments for the existence of God. I've attended lectures by well-known theists and by well-known accommodationists. I read their books. I read their articles. I've even attended courses on religion.

I'm not going to embarrass the theists and accommodationists by listing the really stupid books written by people in the theist camp. John Shook has pointed out the worst of the theist arguments. Here's four books that supposedly represent the best of modern religious arguments for the existence of God ...
  • The Big Questions in Science and religion. by Keith Ward (Regius Professor of Divinity Emeritus, Oxford University), Templeton Foundation Press, West Conshohocken, Pennsylvania (2008)
  • Belief: Reading on the Reason for Faith edited by Francis Collins, HarperOne, New York (2010)
  • Science and Spirituality: Making Room for Faith in the Age of Science by Michael Ruse, Cambridge University Press, New York (2010)
  • The Dawkin's Delusion: Atheist fundamentalism and the denial of the divine. by Alister McGrath and Joanna Collicutt McGrath, published by the Society for Promoting Christian Knowledge (2007)
This brings me to my challenge. I challenge all theists and all their accommodationist friends to post their very best 21st century, sophisticated (or not), arguments for the existence of God. They can put them in the comments section of this posting, or on any of the other atheist blogs, or on their own blogs and websites. Just send me the link.

Try and make it concise and to the point. It would be nice if it's less than 100 years old. Keep in mind that there are over 1000 different gods so it would be helpful to explain just which gods the argument applies to.

I don't care where they post the argument, just get on with it. I'm not interested in any other details about theology. Those points only become relevant once you've convinced this atheist that you have a rational argument for the existence of God. Don't bother telling me how you reconcile your God with evil, or why you believe in miracles, or why transcendence is important in your life, or how many angels can dance on the head of a pin. Don't insult my intelligence by pointing out that religion has done a lot of good things in the past as if that were proof of the existence of the supernatural. Don't be silly enough to try proving god by telling me that religion makes people feel good. So does chocolate, and wine.

Let's stop the whining about how "know-nothing" atheists are ignoring the very best arguments for the existence of God. Come on, all you theists and accommodationists, put your money where your mouth is. Give us something of substance instead of hiding behind The Courtier's Reply. Let's see the angels.

I'm betting that wimps like John Shook and his accommodationist friends don't have a damn clue what they're talking about. I'm betting that they haven't the foggiest notion of any new and sophisticated arguments for the existence of God that the New Atheists haven't already addressed. I'm betting they're just blowing smoke in order to provide cover for their theist friends in the hope of saving them from intellectual embarrassment.1

That's why he says in his article ...
Christian theology has come a long way since St. Thomas Aquinas. Under stress from modern science and Enlightenment philosophy, it has explored cosmological, ethical, emotional, and existential dimensions of religious life. Many kinds of theology have emerged, replacing a handful of traditional arguments for God with robust methods of defending religious viewpoints. There are philosophical atheists who have quietly and successfully kept pace. The discipline of atheology is quite capable of matching these theologies with its skeptical replies, so atheists need not be intimidated. Taking theology seriously enough to competently debate God should not be beneath atheism.
Too bad he doesn't mention even one of those supposedly robust new arguments for the existence of supernatural beings. Could it possibly be because they don't exist?

Guess we'll find out pretty soon. I'll wait for one week.


1. They may also want to be saving themselves since many accommodationists have spent a lifetime studying theology. It must be embarrassing to be told that their life's work is no more important than studying fairy tales.

Our Ancestor Charlemagne: Taller than Average?

 
John Hawks found a paper analyzing the height of Charlemagne (742-814). Rühli et al. (2010) looked at measurements of Charlemagne's left tibia in order to determine his total height and robustness. The result indicates that he was 1.84 m tall (6' 0"). This is considerably taller than the average height of his male contemporaries at 1.69 m (5' 6"). Thus Charlemagne was taller than 99% of the men around him and qualifies as "great" in more ways than one.

The average height of Germans today is 1.78 m (5' 10") and Belgians are a bit taller at 1.795 (5' 10½"). (Charlemagne comes from the area around Liege in Belgium and Aachen in Germany.) Charlemagne would be taller than average in today's society but not notably taller.

The average height of Europeans (men and women) has increased by about 9-10 cm (3½-4") over 1200 years. This isn't as much as most people believe but it's still significant. (Most people who have visited Medieval Castles take note of the small doorways and assume that contemporary Europeans could pass through them without bending over. Not true—they also had to stoop to get through.)

Is this height increase due to evolution or better nutrition? When presenting this question to my students, I point out that you can only answer the question if you have a good definition of evolution. The definition of evolution I prefer is, "Evolution is a process that results in heritable changes in a population spread over many generations." The key word here is "heritable." In order for average height to be an example of evolution you have to show that the genetic composition of today's European population is different from that of 1200 years ago. In other words, a change in frequency of "tallness" alleles accounts for the change in height.

That's not very likely, so we're not talking about evolution here.

Recall that Charlemagne is almost certainly your ancestor as long as you have some Europeans in your family tree [Are You a Descendant of Charlemagne?]. I happen to know how I'm connected to Charlemagne [My Family and Other Emperors] but he's almost certainly your ancestor even if you don't do genealogy.

Does that mean we all descend from a taller-than-average 9th century European therefore it's no surprise that all Europeans are taller today? No it doesn't mean that at all. Charlemagne is your ancestor—if you are of European descent—but so is everyone else who lived around him. That includes the pig farmer who lived in Herstal, and the midwife in Aix-la-Chapelle. They were average people. Some of them were much shorter than average.


[Hat Tip: John Hawks: Charlemagne the Tall.

Rühli, F.J., Blümich, B., and Henneberg, M. (2010) Charlemagne was very tall, but not robust. Economics & Human Biology 8:289-290. [doi:10.1016/j.ehb.2009.12.005]

Four Nails Exposed

 
It is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but I’d rather not consider that).

Richard Dawkins
I know many of you have been anxiously awaiting the report of last night's meeting at Southern Methodist University. You know, the one where the Four Nails in Darwin's Coffin were revealed to the general public for the first time?

Here's the summary from Disco [Standing Room Only Crowd Treated to Serious Discussion of the Scientific Demise of Darwinism].
CSC's Stephen Meyer moderated the discussion after the film which included four serious challenges to Darwinian evolution. The first speaker was evolutionary biologist Richard Sternberg who presented the challenge of population genetics to Darwin's Theory. He was followed by Biologic Institute's Doug Axe who spoke on the challenge of finding functional proteins, and CSC Fellow Paul Nelson who explained why evolving animal body plans by random mutation and natural selection is probably impossible. CSC biologist Jonathan Wells concluded the short presentations by explaining the challenge of ontogenetic information. The evening closed with a robust 40 minutes of questions from the audience.
Ohmygod! They snuck in a ringer, Paul Nelson. I didn't know he was going to be there. No fair!

As far as I can gather from this short summary, the four nails are:
1. Population genetics challenges Darwin's Theory. Not much of a surprise here since populations genetics was only developed in the 1920s and 1930s. That's at least sixty years after publication of the Origin of Species. The Modern Synthesis, on the other hand, was specifically developed to take advantage of the new understanding of evolution that arose from population genetics. The Modern Synthesis dates from the 1940s suggesting that Richard Sternberg still has a lot of learnin' ahead of him. Either that, or he is deliberately misleading his audience by referring to "Darwin's Theory." That would be wicked and, like Richard Dawkins', I don't want to consider that.1

2. The Challenge of Finding Functional Proteins. This probably refers to Doug Axe's work on mapping protein folds to an adaptive landscape. He is fascinated by the appearance of peaks corresponding to low free energy wells for each of the main types of fold. While staring at these figures he finds it easy to imagine that God made all of these folds and that it is impossible for any of them to evolve from some intermediate state. Real scientists don't have a problem explaining those peaks from an evolutionary perspective. But then, real scientists understand evolution and that gives them an unfair advantage.

3. Evolving Animal Body Plans by Random Mutation and Natural Selection is Probably Impossible. Paul Nelson defines himself as a Young Earth Creationist [Paul Nelson Is Confused] so it's safe to conclude that there isn't much about evolution that he likes. It's probably also safe to assume that his understanding of evolution leaves a lot to be desired since his "nail" is restriced to natural selection. (His readings in evolution may have stopped at the same place as Sternberg's.) I can't imagine why he thinks that evolving body plans is impossible. Most of the arguments along those lines have been refuted decades ago. What's the "new challenge," Paul?

4. Challenge of Ontogenetic Information. Jonathan Wells is famous for The Icons of Evolution where he had ten (10) serious challenges to evolution.1 At least we're making progress—now we're down to only four and the first two weren't even mentioned in Icons. The word "ontogeny" refers to development. I assume that "ontogenetic information" refers to the program of development involving the differential expression of genes at different times. Maybe he's referring to Evo-Devo (Evolutionary Developmental Biology). He could be referring to one of the "icons" in his ten-year old book because he criticized the current molecular understanding of development in a chapter celled "Four-Winged Fruit Flies." If that's the challenge he talked about last night, then it's hardly new. West's ideas were refuted even before he published his book in 2000.
There you have it, folks. Lot's like more of the same-old, same-old, criticism of science that's come to characterize the Intelligent Design Creationist movement. They never offer any evidence for a designer and they never tell us how they explain the "challenges" based on Intelligent Design Creationism.

They make extensive use of false dichotomy by assuming there are only two possible explanations for a biological phenomenon—their (usually false) version of evolution, or creationism. By "refuting" their strawman version they assume that the only alternative is creationism.

Now do you understand why we call them IDiots?


1. Not.

The Spinning Dancer

 

This image of The Spinning Dancer pops up frequently in advertisements on ScienceBlogs. I find it fascinating. If I concentrate hard I can make the dancer switch from spinning right to spinning left (and vice versa) but I can't tell you how to do it and I can't always succeed.

How about you? Can you make her switch? Is it easy or hard? Do you prefer one direction over another? I my case, I have trouble switching her from clockwise spinning to counter-clockwise spinning but not the other way around.

What Is Naturopathy?

 
A lot of people have asked me about naturopathy and what I think of it. I've usually said that some of it might be okay since it's based on herbs and things that might actually contain real medicine. In fact, I really don't know much at all about the differences between "naturopathic medicine" and quackery.

So I decided to look at an authoritative source, the Canadian College of Naturopathic Medicine right here in Toronto. The college, "offers a rigorous four-year, full-time doctor of naturopathic medicine program."

Here's how CCNM describes naturopathy.
Naturopathic medicine is:

... a distinct system of primary health care that addresses the root causes of illness, and promotes health and healing using natural therapies. It supports your body's own healing ability using an integrated approach to disease diagnosis, treatment and prevention that includes:

o acupuncture/Asian medicine
o botanical medicine
o physical medicine (massage, hydrotherapy, etc.)
o clinical nutrition
o homeopathic medicine
o lifestyle counseling
Good. Now I know the difference between naturopathy and other forms of non-evidence based medicine (i.e. alternative medicine, quackery).

There isn't any.

The Parting of the Red Sea: Science vs. God

 
Yesterday's TorontoStar had an article on the parting of the Red Sea. Apparently, strong winds could account for making a pathway that the chosen people used to cross the sea ahead of the pursuing Egyptians. God wasn't necessary.

My colleagues and I had a good chuckle. What's the point of a "scientific" explanation for an event that never happened? What's next—a "scientific" explanation of how Little Red Riding Hood can survive being eaten by a wolf?

Little did I realize that the newspaper article was based on a paper that got published in a (formerly) reputable journal. One of the authors is a devout Christian who is determined to reconcile science and the Bible.

Read all about it on Jerry Coyne's blog [Parting the Red Sea] or on PZ Myer's blog [Inventing excuses for a Bible story, and getting them published in a science journal?]. This is a pretty clear case of science in the service of religion. It's bad science. It's probably bad religion as well but I'm not an expert on proper superstitious beliefs.


Come As You Are

 
Arriving at the train station this morning I was greeted by an Anglican priest in full regalia. He and his buddies were handing out pamphlets urging us to attend church this Sunday. He was delighted to have his picture taken and took it all in excellent spirit, even though he knew I wasn't religious.

The train station event was part of a "back to church" campaign on behalf of the the Church of England [Bishops' call to 'come as you are' this Sunday].

Don't worry about dressing up. They'll be happy to see you no matter what you're wearing.

Cute idea. If you have to go to church next Sunday then your local Anglican church in Canada or the UK is far better than some of the alternatives.

The fact that churches are having to advertise is a very good sign. It brought a smile to my face and made my day.

Cool outfit, by the way.



Four Nails in Darwin's Coffin

 
Charles Darwin died on April 19, 1882 and he was buried in Westminster Abbey on Wednesday, April 26, 1882.

The IDiots have just realized that Darwin is dead. Tonight they will celebrate the event by presenting four discoveries that are not very well explained by Darwin's original theory of natural selection, published in 1859. (That's 151 years ago.) The "four nails" will be revealed at an event being held at Southern Methodist University.

I predict these "nails" are either gross misunderstandings of real science or discoveries that are explained by modern evolutionary theory. I'm pretty confident about this prediction since I know the reputation of the four hammers at the conference. They are ...

Douglas Axe, who thinks that the evolution of new protein folds is impossible.

Richard Sternberg, worries about what a gene is and about the relationship between genotype and phenotype.

Jonathan Wells, who's fond of making up elaborate tales about why evolution is wrong.

Stephen Meyer, who thinks that 2oth1 century biochemistry and molecular biology disprove evolution.

I wonder if we're going to get any honest reporting on this event or whether journalists will rely entirely on DISCO press releases?


1. No, this is not a mistake. Meyer hasn't yet made it into this century. Neither have the other IDiots.
