Steven Pinker on Francis Collins

July 11, 2009 • 6:50 am

Some newspapers and science journals have called atheist-scientists this week, asking for opinions on Francis Collins’s appointment as head of the National Institutes of Health.  In lieu of a phone interview,  Steve Pinker wrote the following to a reporter from one such journal  (copy slightly edited for web publication).  Thanks to Steve for permission to post.

I have serious misgivings about Francis Collins being appointed director of NIH. It’s not that I think that there should be a religious litmus test for public science administrators, or that being a devout Christian is a disqualification. But in Collins’s case, it is not a matter of private belief, but public advocacy. The director of NIH is not just a bureaucrat who tends the money pipleline between the treasury and molecular biologists (which is how many scientists see the position). He or she is also a public face of science, someone who commands one of the major bully pulpits for science in the country. The director testifies before Congress, sets priorities, selects speakers and panelists, and is in many regards a symbol for biomedical research in the US and the world. In that regard, many of Collins’s advocacy statements are deeply disturbing.

For example, I see science as not just cures for diseases and better gadgets but an ideal for how to think about the most important issues facing us as humans– in particular, the ideal that we should seek truth through reason and evidence and not through superstition, dogma, and personal revelation. Collins has said that he came to accept the Trinity, and the truth that Jesus is the son of God, when he was hiking and came upon a beautiful triple waterfall. Now, the idea that nature contains private coded messages from a supernatural being to an individual person is the antithesis of the scientific (indeed, rational) mindset. It is primitive, shamanistic, superstitious. The point of the scientific revolution was to do away with such animistic thinking.

This is not just autobiographical. Collins, in his book, eggs on fellow evangelical Christians in their anti-scientific beliefs. He tells them that they are “right to hold fast to the truths of the Bible” and to “the certainty that the claims of atheistic materialism must be steadfastly resisted.” Granted, he is not a young-earth or intelligent-design creationist. But he has stated that God interacts with creation, in particular, that he designed the evolutionary process to ensure that human intelligence, morality, and Judaeo-Christian religious belief would evolve.

That is far more than just expressing an opinion. That is advocacy, which gives incalculable encouragement the forces that have been hostile to science for the past eight years. And this is not just a theoretical fear: a number of right-wing, religious apologists (e.g., Dennis Praeger, in his debate with Sam Harris) used Collins as a stick to beat secularists:  “Here is a famous scientist who takes an interventionist God and the Bible seriously; who are you to contradict him?” This is going to be multiplied if Collins becomes an even more prominent face of science.

Also, the human mind and brain constitute one of the frontiers of biomedical science. Cutting-edge research treats intelligence, morality, and religious belief as products of evolution and neuroscience. The idea that there is divine design and teleology behind these functions, on the basis of Iron Age and medieval dogma, is antithetical to this vibrant research area. How will Collins preside over the allocation of research priorities if he believes in ““the certainty that the claims of atheistic materialism must be steadfastly resisted”?

Again, it’s important that there not be an atheist-litmus-test for science administrators. A person’s private beliefs should not keep him from a public position. But Collins is an advocate of profoundly anti-scientific beliefs, and it is reasonable for the scientific community to ask him how these beliefs will affect his administration of the Institute and his efforts on the behalf of the scientific enterprise in Congress and in public.  At the very least, he should distance himself from the BioLogos Foundation and any other advocacy group.

For more on Collins, see the conversation between him and Richard Dawkins that ran three years ago in Time magazine; it has been reposted on the Dawkins website.  Slate just published a discussion of Collins’s appointment called “Jesus Goes to Bethesda.” I weighed in yesterday.

Francis Collins as NIH director

July 10, 2009 • 8:35 am

I’ve been chewing over what I think of Obama’s picking Francis Collins as head of the National Institutes of Health. (See the New York Times piece here, which includes some reactions by other scientists.)  I guess my first reaction would be to give the guy a break, and take a wait-and-see attitude towards his stewardship of the NIH.  After all, he doesn’t seem to have let his superstition get in the way of his other administrative tasks, and he doesn’t seem to be the vindictive type, either. (I do have an NIH grant!)  I won’t grouse too much about this, but do want to emphasize again that the guy is deeply, deeply superstitious, to the point where, on his website BioLogos and his book The Language of God, he lets his faith contaminate his scientific views.  So I can’t help but be a bit worried.   Two more reactions:

1. I expect Collins to resign from BioLogos if he wants to maintain any scientific credibility.  Yes, the guy has every right to believe what he wants, but a director of the nation’s most prestigious research foundation has to have some standards, and BioLogos is beyond the pale.  Mixing science with faith as it does, it gives people the wrong view of what science is all about and gives his official imprimatur to essentially private beliefs.  Certainly, private expressions of faith are absolutely fine, but Collins has chosen to make his views public, and discuss their relationship to science.  Deism is one thing, but to find God in quantum uncertainty, or to see the evolution of humanoids as inevitable, are pollutions of science.  I will continue to criticize BioLogos for their mush-brain-ness, and will include Collins’s name if he’s still associated with it.

2.  Think about this:  would a nonbelieving scientist who was as vociferous an atheist as Collins is a Christian have any chance to get the NIH spot? I don’t think so.  And a Scientologist who publicly espoused his belief in Xenu and thetans would be considered too much of a lunatic to have responsibility for the NIH. But of course Christianity is a publicly acceptable form of superstition, and Scientology is not.

I had hoped that Obama might end governmental coddling of faith, but it doesn’t look like a lot has changed.

The Hall of Shame: God, evolution, and quantum mechanics

July 5, 2009 • 8:28 am

For those who claim that no religious scientists allow their scientific statements and beliefs to be infected with religion, here’s a counterexample.  It’s from Francis Collins’s BioLogos website (funded by our friends at The John Templeton Foundation) and is a statement about how God may influence the world through quantum mechanics:

The mechanical worldview of the scientific revolution is now a relic. Modern physics has replaced it with a very different picture of the world. With quantum mechanical uncertainty and the chaotic unpredictability of complex systems, the world is now understood to have a certain freedom in its future development. Of course, the question remains whether this openness is a result of nature’s true intrinsic chanciness or the inevitable limit to humans’ understanding. Either way, one thing is clear: a complete and detailed explanation or prediction for nature’s behavior cannot be provided. This was already a problem for Newtonian mechanics; however, it was assumed that in principle, science might eventually provide a complete explanation of any natural event. Now, though, we see that the laws of nature are such that scientific prediction and explanation are ultimately limited.

It is thus perfectly possible that God might influence the creation in subtle ways that are unrecognizable to scientific observation. In this way, modern science opens the door to divine action without the need for law breaking miracles. Given the impossibility of absolute prediction or explanation, the laws of nature no longer preclude God’s action in the world. Our perception of the world opens once again to the possibility of divine interaction.

This view is nearly identical to that of Kenneth Miller in his book Finding Darwin’s God.  What this means, of course, is that what appear to us to be random and unpredictable events on the subatomic level (for example, the decay of atoms) can really reflect God’s manipulation of those particles, and that this is the way a theistic God might intervene in the world.  And of course these interventions are said to be “subtle” and “unrecognizable.” (Theologians are always making a virtue of necessity.  They never explain why, if God wanted to answer a prayer, he would do it by tweaking electrons rather than, say,  directly killing cancer cells with his omnipotence. After all, a miracle is a miracle.  Theology might, in fact, be defined as the art of making religious virtues out of scientific necessities.)  And why did these interventions used to involve more blatant manipulations of nature (several thousand years ago, virgin human females gave birth to offspring, were taken bodily to heaven, and their offspring brought back to life after dying), while  in more recent years the manipulations have been confined to the subatomic level?

And think about how ludicrous this theology really is.  God:  “Well, let’s see.  Johnny’s parents have prayed for a cure for his leukemia.  They’re good people, so I’ll do it.   Now how to do the trick?.  If I can just change the position of this electron here, and that one over there, I can cause a mutation in gene X that will beef up his immune system and allow the chemotherapy to work.”  Why can’t God just say “Cancer, begone!”?  (He apparently did that in Baltimore.) I already how the theists will respond:  “That’s not the way God works, because we know how he works and it’s not that way!”

The BioLogos statement appears as part of the answer to the question, “What role could God have in evolution?”  I submit that the statement is a scientific one that is deeply infected with religious views.  The statement is this:  “God acts by tweaking electrons and other subatomic particles, constantly causing non-deterministic changes in the universe according to his desires.” Further, the clear implication is this:  “God intervened in the evolutionary process, tweaking some electrons to eventually ‘evolve’ a creature made in his image”.  That is a religious statement masquerading as science. And that appears to be the view of some religious theists, especially those Catholics who adhere to the Church’s position that God intervened in human evolution.

Well, what happens if we find out some day that the subatomic “nondeterministic” changes really turn out to be deterministic?  After all, quantum mechanics and its indeterminacy are provisional scientific theories; we might eventually find out that what appear to be totally unpredictable events really do have a deterministic causation.  Where does Collins’s deity go then?  Do you suppose for a minute that Collins and his fellow theistic evolutionists would say, “Right. Everything is in principle predictable after all.  Obviously, there’s no room for God to intervene in nature, so theism is wrong.”  I wouldn’t count on it.

Making quantum mechanics the bailiwick for celestial intervention is a God-of-the-gaps argument, no different in kind from many arguments for intelligent design. Do theistic evolutionists really want to make quantum mechanics God’s playground?  Remember the words of the martyred theologian Dietrich Bonhoeffer about the dangers of mixing science and faith:

If in fact the frontiers of knowledge are being pushed farther and farther back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat.

Collins may be NIH director

May 27, 2009 • 6:07 am

Well, we thought we’d seen the last of the theocracy of George W. Bush, but it apparently ain’t so.  The Scientist reports (and this has been the buzz for weeks), that born-again Christian and BioLogos Foundation director Francis Collins is likely to be named as head of the National Institutes of Health:

Francis Collins, the geneticist who led the Human Genome Project, is close to taking over the top spot at the National Institutes of Health, according to areport by Bloomberg News.

Collins, who was the director of the NIH’s National Human Genome Research Institute from 1993 to 2008, is in the final stages of being screened by the administration of US President Barack Obama, an unnamed source toldBloomberg.

Elias Zerhouni, Collins’ would-be predecessor, voiced his approval for the pick, telling Bloomberg that Collins has “done things many scientists wish they could do once in their lifetime, and he’s done it repeatedly.”

Collins recently unveiled a new foundation, BioLogos, that promotes “the search for truth in both the natural and spiritual realms, and seeks to harmonize these different perspectives,” according to the organization’s Web site. Collins, who is an evangelical Christian, has said that his new foundation is an attempt to resolve Christian faith with scientific evidence, especially with regard to evolution. In 2006 he published a bestselling book, The Language of God: A Scientist Presents Evidence for Belief, that stirred some controversy in the scientific community.

I am funded by the NIH, and I’m worried.  Not about my own funding (although I’m a heathen cultural Jew), but about how this will affect things like stem-cell research and its funding.  If appointed, Collins will have wide latitude in how to disperse the  $30 billion annual budget, and can steer it towards or away from various projects.  I’d  be much more comfortable with someone whose only agenda was science, and did not feel compelled to set up a highly-publicized website demonstrating how he reconciles his science with Jesus.  (Truthdig has published Sam Harris’s evisceration of Collins’s wacko book.)

We are just recovering from the theocracy of G. W. Bush, and I was happy that federally-funded stem-cell research was allowed to go ahead.  Now what will happen?  This is NOT a presidential appointment designed to smooth the waters roiled by our previous administration.

Collins may indeed be a good administrator, but this appointment is a mistake.  At the very least, Collins must remove himself as director of the BioLogos foundation, as holding both posts would represent an unwanted incursion of religion into the public sphere.  I call for him to resign from BioLogos if he’s appointed as head of the NIH. (That, of course, has the attendant benefit of putting the ever-amusing Karl Giberson in charge of BioLogos!)

Karl Giberson defends accommodationism

May 26, 2009 • 8:37 am

Karl Giberson, whose accommodationist book Saving Darwin I reviewed in The New Republic, is vice president of The BioLogos Foundation, the Templeton-Foundation-Funded organization headed by born-again Christian Francis Collins.  Giberson is also a trained physicist, a professor at Eastern Nazarene College, and head of a faith and science initiative at Gordon College.

I criticized Saving Darwin — and BioLogos as well — for their insistence that the evolution of human beings (or of some humanlike form of devout animal) was inevitable.  As part of a scheme to accommodate evolution with Jesus, BioLogos (and other accommodationists like Kenneth Miller  and John Haught) must devise a way to reconcile naturalistic evolution with the Christian view that humans were made in the image of God as the goal of the whole creation.  This magic is accomplished by claiming that God either set up the evolutionary process so that it would produce H. sapiens as an inevitable outcome, or that He intervened at some juncture(s) to ensure that humans would appear.  Either way, such a view completely violates the scientific presumption (and evidence) that evolution is a purely materialistic and unguided process — a process without a goal or, indeed, any determined outcome.

A weekly feature of BioLogos (which provides hours of entertainment and nanoseconds of enlightenment) is “Science and The Sacred,” a weekly online column where “leaders of the BioLogos Foundation share insights on the latest ideas in science, faith and their integration.”  In this week’s column Giberson takes on yours truly:

God or Matter?

The University of Chicago biologist Jerry Coyne recently objected to the suggestion that humans might actually be a part of God’s creative plan. Like most of the so-called “new atheists,” he denounces the idea that evolution — all by its lonesome, blind, purposeless, unguided self — would ever find its way to such an improbably unique species as human beings.

Although we know a lot more than we used to about evolution, I don’t see how we can have any certainty whatsoever about what kinds of things evolution might or might not be able to do. It was not long ago we thought 100,000 genes were required to make a human being, and now we know it can be done with approximately 20,000, or roughly the same number as rice and sea urchins. There is a lot we still don’t know about how evolution works, but this is not the point I want to make, for I have no desire to hide inside the shadowy corners of science and hope that they are never illuminated by the light of scientific progress.

Coyne’s objections are really just the traditional objections to belief in God repackaged as scientific objections. Traditional theism — which is the foundation for a majority of people’s worldviews, including scientists — is a richer and more complex version of reality than materialism. As a theist with a deep respect for science, I believe in all the same remarkable laws and particles that undergird the worldviews of scientists. But I also believe this reality is rooted in the creative and sustaining activity of God. God can act in the world and provide a larger understanding of the way things are.

Theists have both God and science as important parts of their reality. But many Americans reject particular scientific ideas like evolution or the big bang theory because they think they are incompatible with belief in God. The BioLogos Foundation is committed to helping religious people make peace with such scientific ideas, a project Coyne describes as a “hilarious goldmine of accomodationism.”

But what about the accommodationism of materialists? How do they reconcile their materialism with the rationality of the world? It seems to me reality has to be grounded in one of two deeply mysterious foundations: God or matter. Each has its own set of questions. Theists wonder about the nature of God’s existence, the problem of evil, how and why God acts in the world and why God has chosen to remain hidden from us. These are difficult questions and certainly must trouble thoughtful believers. But don’t materialists have another set of mysteries? Don’t they have to wonder about the nature of physical existence? Why is there something rather than nothing? Why are the laws of nature so rational? Why is our species so religious? Is the world just a big pointless accident?

In Coyne’s excellent book, Why Evolution is True, he suggests we can “make our own purposes, meaning, and morality.” I know I am not alone when I say I am not entirely satisfied with this. I think the materialists have their own accommodationist project to work on, and I suspect it may turn out to be even more hilarious than ours.

Karl Giberson is executive vice president of The BioLogos Foundation and director of the Forum on Faith and Science at Gordon College in Wenham, Mass.

Well, I appreciate Giberson’s praise for my book but still disagree strongly with his views.  First of all, he mischaracterizes mine: “[Coyne] denounces the idea that evolution — all by its lonesome, blind, purposeless, unguided self — would ever find its way to such an improbably unique species as human beings.”

Not so. I never said this. Indeed, this would be a moronic assertion, since blind, purposeless evolution has found its way to human beings.  My position has always been that the evolution of human beings may not have been inevitable, nor is there any way we can confidently assert from the facts of science that it was.  I won’t go over my arguments, which you can find in The New Republic piece.  The onus is on crypto-creationists like Giberson and Miller to show that the nature of selection, environmental change, and genetic mutation makes the evolution of a creature with humanlike intelligence and rationality an inevitable outcome.  This they have not done, though they must if they wish to reconcile an inevitable appearance of humanoids with straight, undiluted Darwinism.

And Giberson claims that we rationalists have our own set of problems:  “Don’t they have to wonder about the nature of physical existence? Why is there something rather than nothing? Why are the laws of nature so rational? Why is our species so religious? Is the world just a big pointless accident?”

The answer to the last question is “yes — so what?”   And why is there something rather than nothing? As physicist Victor Stenger has shown repeatedly (don’t these guys ever read him?), the answer is “because ‘nothing’ is unstable.”

Why is our species so religious?  We’re working on that, and there are lots of answers that don’t include the existence of celestial deities.

Finally, why are the laws of nature so rational?  That’s a dumb question. The laws of nature aren’t rational: WE are rational, and there are good reasons, based on natural selection and culture, why we should be.

The point is that there are provisional but testable answers to the questions that “plague” us rationalists (for example, physicists’ theories about how our universe came into being), but no testable answers to the questions that trouble supernaturalists like Giberson.  Take the existence of evil: we will never know why, if there is a god, innocent people undergo needless suffering (e.g., the death of children from horrible diseases and the death of thousands from “acts of God” like tsunamis).  There are lots of theological answers (every one ridiculous), and no way to discriminate among them. Indeed, the most sensible answer to the problem of evil is that there simply is no god.  I, for one, am content with the idea that bad things like tsunamis happen to good people for no reason at all other than movements of the Earth’s crust, and that small children get leukemia or cholera because of random mutations or the evolution of pathogenic organisms.

Behind all this, I think, is the longing for the “richer and more complex view of reality” that Giberson finds in religion.  But what could be richer or more complex than the material universe as we have it — a universe full of great mysteries and wonderful things to find out?  What Giberson means by “a richer and more complex view” is “after I die I’ll be able to meet my dead relatives in the sky.”  Such a view may be more complex, but it’s not richer.  It’s impoverished by adherence to magic and superstition.

Why the evolution of humans was NOT inevitable; BioLogos peddles more dubious science

May 13, 2009 • 7:21 am

Over at that hilarious goldmine of accommodationism, Francis Collins’s BioLogos website (generously supported by The Templeton Foundation, they have posted an answer to the question, “Did evolution have to result in human beings?” Now if you know anything about this history of faith/science accommodationism, you know that the answer has to be “yes”, at least if you construe the question to mean “Did evolution have to result in a rational, highly intelligent being that was capable of apprehending and worshiping its creator?”  If God is running the evolutionary process, as the accommodationists maintain, then the evolution of humans (who are, after all, the goal of this process — the one species made in God’s image) could not have been left to chance.

And so, religious biologists like Kenneth Miller and Francis Collins, and “science-friendly” theologians like John Haught, have maintained in their writings that evolution would inevitably have coughed up an intelligent rational creature like Homo sapiens.  In other words, contrary to the assertions of Stephen Jay Gould, if we re-ran the tape of life, something humanlike would always appear.  Religious apologists always contend that the evolution of what we will call “humanoids” was not a continent process: it was built by God into the very fabric of evolution.

Of course, this is not a scientific belief.  For one thing, it makes humans different from other creatures.  The faithful don’t go around maintaining that the evolution of squirrels or cockroaches was an inevitable outcome of the evolutionary process, because according to Scripture God didn’t make rodents of insects in His image.  So God stuck his hand in, somewhere, to make humanoids appear.  That is creationism, pure and simple.  Or, he designed the process with the foreknowledge that humans would appear, which is also creationism, since no evolutionist really thinks that the process was jerry-rigged from the outset to produce certain life forms.

Second, if you do believe in a naturalistic and materialistic process of evolution in which God didn’t interfere, then the appearance of humans doesn’t seem likely at all — and certainly not inevitable.  Higher intelligence and rationality evolved only once, so it certainly isn’t something like eyes (whose morphology evolved independently dozens of time).  The idea that “convergent evolution” shows that humans were inevitable is deeply fallacious.

Yet BioLogos uses this argument — a favorite of the religious paleontologist Simon Conway Morris –to show that (surprise!) something like humans WAS inevitable in evolution.  After disposing of Gould’s contingency argument, they then approvingly reiterate Conway Morris’s “convergence” argument:

Humans: Inevitable, Intentional

Simon Conway Morris presents a different perspective, arguing humans, or a human-like species, are actually an inevitable part of evolution.  Morris is not proposing a different mechanism for human evolution, merely a different observation of its possible outcomes.  Morris would agree that any slight difference in the history of human DNA would result in a different evolutionary path.  Unlike Gould, however, Morris argues each of those possible pathways would inevitably lead to something like the human species.  Morris writes:

“The prevailing view of evolution is that life has no direction — no goals, no predictable outcomes. Hedged in by circumstances and coincidence, the course of life lurches from one point to another. It is pure chance that 3 billion years of evolution on Earth have produced a peculiarly clever ape. We may find distant echoes of our aptitude for tool making and language and our relentless curiosity in other animals, but intelligence like ours is very special. Right?”

“Wrong! The history of life on Earth appears impossibly complex and unpredictable, but take a closer look and you’ll find a deep structure. Physics and chemistry dictate that many things simply are not possible, and these constraints extend to biology. The solution to a particular biological problem can often only be handled in one of a few ways, which is why when you examine the tapestry of evolution you see the same patterns emerging over and over again.”

The patterns Morris mentions are also referred to as convergences in the evolutionary process.  In his most recent book, Life’s Solution, Morris gives many examples of physical traits or abilities found repeatedly among different species.5 Normally, such similarities are understood asthe result of common ancestry.  However, the species in Morris’s examples are known to be distantly related.  In many cases, not even these species’ common ancestor shared the same trait.  The implication is that several different species have independently developed similar traits.

The examples of convergence range across many levels of biology.  One popular and straightforward example is the human eye.  It turns out that several other species share a nearly identical visual system to that of the human eye, including the octopus.6 However, humans and octopuses have separate predecessors, neither of which shared this characteristic.  Two very different evolutionary paths arrived at the same visual system.  If Gould’s supposition is correct, and there was an infinity of other possible outcomes, then this example of convergence is all the more improbable.  Morris’s argument, conversely, is that the laws of nature allow for only a few solutions to any particular problem.  It appears the eye has developed independently at least seven times over the course of evolutionary time.

Human Significance

To see evidence for human significance, one need only consider Morris’s examples of convergence for many of the traits that are particularly relevant for human-like beings.  These examples include basic senses like balance, hearing and vision, as well as highly advanced features like the human brain.  Morris argues that evolution does not pose any threat to human significance.  Characteristics such as a large brain capable of consciousness, language and complex thought would inevitably have to emerge from the evolutionary process. Morris writes:

“Contrary to popular belief, the science of evolution does not belittle us.  As I argue, something like ourselves is an evolutionary inevitability, and our existence also reaffirms our one-ness with the rest of Creation.” 7

The exact anatomical features of this ultimate sentient being might not be precisely specified by the evolutionary process, however.  This thought can be unsettling to anyone who imagines our particular body plan is part of the imago Dei, or image of God. Despite the marvelous paintings in the Sistine Chapel, there is no reason to think that God the Father has a physical body that looks like ours.

God’s Sovereignty in the Evolution of Humans

Belief in a supernatural creator always leaves open the possibility that human beings are a fully-intended part of creation.  If the Creator chooses to interact with creation, he could very well influence the evolutionary process to ensure the arrival of his intended result.  (See Question 14 about Evolution and Divine Action.)  Furthermore, an omniscient creator could easily create the universe in such a way that physical and natural laws would result in human evolution.  (See Question 19 about Fine-Tuning of our Universe.)

Although the unpredictable mutations of DNA can make any species appear entirely accidental, Simon Conway Morris also puts forward strong arguments in favor of the inevitability of creatures that have the attributes of humans.  From this perspective, it seems the evolutionary process itself might be geared toward human life.

So it goes. (By the way, have a look at the last paragraph of this page where BioLogos suggests that the evolution of humanoids ON OTHER PLANETS was  improbable. (As expected, they take this stand because theologists can’t see God sending Jesus careening from planet to planet to save every species of alien).

The Argument for the Inevitability of Humanoids is perhaps the most popular argument (ranking with The Fine Tuning of Physical Constants) used by accommodists to show that evolution and God are not in conflict.  But the argument is simply wrong.  Nobody can say with assurance that the evolution of humanoids was inevitable.  The only honest response is “We don’t know” (and I would add “what we know about evolution tells us that it was probably not inevitable.”)

I attacked this argument in my New Republic essay “Seeing and Believing,” and for those who haven’t read it, or who don’t wish to plow through the link to find it, I’ll reproduce it here. This was a review of two books, Kenneth Miller’s Only a Theory: Evolution and the Battle for America’s Soul, and Karl Giberson’s Saving Darwin: How to be a Christian and Believe in Evolution.

III.

In Finding Darwin’s God, his earlier book, Miller proclaimed a universal theism: “Remember, once again, that people of faith believe their God is active in the present world, where He works in concert with the naturalism of physics and chemistry.” Giberson clearly agrees. And where do they find the hand of God in nature? Unsurprisingly, in the appearance of humans.

Giberson and Miller assert that the evolution of humans, or something very like them, was inevitable. Given the way that evolution works, they claim, it was certain that the animal kingdom would eventually work its way up to a species that was conscious, highly intelligent, and above all, capable of apprehending and worshipping its creator. This species did not have to look perfectly human, but it did have to have our refined mentality (call it “humanoid”). One of Miller’s chapters is even titled “The World That Knew We Were Coming.” Giberson notes that “capabilities like vision and intelligence are so valuable to organisms that many, if not most biologists believe they would probably arise under any normal evolutionary process…. So how can evolution be entirely random, if certain sophisticated end points are predictable?”

Reading this, many biologists will wonder how he can be so sure. After all, evolution is a contingent process. The way natural selection molds a species depends on unpredictable changes in climate, on random physical events such as meteor strikes or volcanic eruptions, on the occurrence of rare and random mutations, and on which species happen to be lucky enough to survive a mass extinction. If, for example, a large meteor had not struck Earth sixty-five million years ago, contributing to the extinction of the dinosaurs–and to the rise of the mammals they previously dominated–all mammals would probably still be small nocturnal insectivores, munching on crickets in the twilight.

Evolutionists long ago abandoned the notion that there is an inevitable evolutionary march toward greater complexity, a march that culminated in humans. Yes, the average complexity of all species has increased over the three-and-a-half billion years of evolution, but that is because life started out as a simple replicating molecule, and the only way to go from there is to become more complex. But now complexity is not always favored by natural selection. If you are a parasite, for instance, natural selection may make you less complex, because you can live off the exertions of another species. Tapeworms evolved from free-living worms, and during their evolution have lost their digestive system, their nervous system, and much of their reproductive apparatus. As I tell my students, they have become just absorptive bags of gonads, much like the students themselves. Yet tapeworms are superbly adapted for a parasitic way of life. It does not always pay to be smarter, either. For some years I had a pet skunk, who was lovable but dim. I mentioned this to my vet, who put me in my place: “Stupid? Hell, he’s perfectly adapted for being a skunk!” Intelligence comes with a cost: you need to produce and to carry that extra brain matter, and to crank up your metabolism to support it. And sometimes this cost exceeds the genetic payoff. A smarter skunk might not be a fitter skunk.

To support the inevitability of humans, Giberson and Miller invoke the notion of evolutionary convergence. This idea is simple: species often adapt to similar environments by independently evolving similar features. Ichthyosaurs (ancient marine reptiles), porpoises, and fish all evolved independently in the water, and through natural selection all three acquired fins and a similar streamlined shape. Complex “camera eyes” evolved in both vertebrates and squid. Arctic animals such as polar bears, arctic hares, and snowy owls either are white or turn white in the winter, hiding them from predators or prey. Perhaps the most astonishing example of convergence is the similarity between some species of marsupial mammals in Australia and unrelated placental mammals that live elsewhere. The marsupial flying phalanger looks and acts just like the flying squirrel of the New World. Marsupial moles, with their reduced eyes and big burrowing claws, are dead ringers for our placental moles. Until its extinction in 1936, the remarkable thylacine, or Tasmanian wolf, looked and hunted like a placental wolf.

Convergence tells us something deep about evolution. There must be preexisting “niches,” or ways of life, that call up similar evolutionary changes in unrelated species that adapt to them. That is, starting with different ancestors and fuelled by different mutations, natural selection can nonetheless mold bodies in very similar ways–so long as those changes improve survival and reproduction. There were niches in the sea for fish-eating mammals and reptiles, so porpoises and ichthyosaurs became streamlined. Animals in the Arctic improve their survival if they are white in the winter. And there must obviously be a niche for a small omnivorous mammal that glides from tree to tree. Convergence is one of the most impressive features of evolution, and it is common: there are hundreds of cases.

All it takes to argue for the inevitability of humanoids, then, is to claim that there was a “humanoid niche”–a way of life that required high intelligence and sophisticated self-consciousness–and that this niche remained unfilled until inevitably invaded by human ancestors. But was its occupation really inevitable? Miller is confident that it was:

“But as life re-explored adaptive space, could we be certain that our niche would not be occupied? I would argue that we could be almost certain that it would be–that eventually evolution would produce an intelligent, self-aware, reflective creature endowed with a nervous system large enough to solve the very same questions we have, and capable of discovering the very process that produced it, the process of evolution…. Everything we know about evolution suggests that it could, sooner or later, get to that niche.”

Miller and Giberson are forced to this view for a simple reason. If we cannot prove that humanoid evolution was inevitable, then the reconciliation of evolution and Christianity collapses. For if we really were the special object of God’s creation, our evolution could not have been left to chance. (It may not be irrelevant that although the Catholic Church accepts most of Darwinism, it makes an official exception for the evolution of Homo sapiens, whose soul is said to have been created by God and inserted at some point into the human lineage.)

The difficulty is that most scientists do not share Miller’s certainty. This is because evolution is not a repeatable experiment. We cannot replay the tape of life over and over to see if higher consciousness always crops up. In fact, there are good reasons for thinking that the evolution of humanoids was not only not inevitable, but was a priori improbable. Although convergences are striking features of evolution, there are at least as many failures of convergence. These failures are less striking because they involve species that are missing. Consider Australia again. Many types of mammals that evolved elsewhere have no equivalents among marsupials. There is no marsupial counterpart to a bat (that is, a flying mammal), or to giraffes and elephants (large mammals with long necks or noses that can browse on the leaves of trees). Most tellingly, Australia evolved no counterpart to primates, or any creature with primate-like intelligence. In fact, Australia has many unfilled niches–and hence many unfulfilled convergences, including that prized “humanoid” niche. If high intelligence was such a predictable result of evolution, why did it not evolve in Australia? Why did it arise only once, in Africa?

This raises another question. We recognize convergences because unrelated species evolve similar traits. In other words, the traits appear in more than one species. But sophisticated, self-aware intelligence is a singleton: it evolved just once, in a human ancestor. (Octopi and dolphins are also smart, but they do not have the stuff to reflect on their origins.) In contrast, eyes have evolved independently forty times, and white color in Arctic animals appeared several times. It is hard to make a convincing case for the evolutionary inevitability of a feature that arose only once. The elephant’s trunk, a complex and sophisticated adaptation (it has over forty thousand muscles!), is also an evolutionary singleton. Yet you do not hear scientists arguing that evolution would inevitably fill the “elephant niche.” Giberson and Miller proclaim the inevitability of humanoids for one reason only: Christianity demands it.

Finally, it is abundantly clear that the evolution of human intelligence was a contingent event: contingent on the drying out of the African forest and the development of grasslands, which enabled apes to leave the trees and walk on two legs. Indeed, to maintain that the evolution of humans was inevitable, you must also maintain that the evolution of apes was inevitable, that the evolution of primates was inevitable, that the rise of mammals was inevitable, and so on back through dozens of ancestors, all of whose appearances must be seen as inevitable. This produces a regress of increasing unlikelihood. In the end, the question of whether human-like creatures were inevitable can be answered only by admitting that we do not know–and adding that most scientific evidence suggests that they were not. Any other answer involves either wishful thinking or theology.

Miller opts for theology. Although his new book does not say how God ensured the arrival of Homo sapiens, Miller was more explicit in Finding Darwin’s God. There he suggested that the indeterminacy of quantum mechanics allows God to intervene at the level of atoms, influencing events on a larger scale:

“The indeterminate nature of quantum events would allow a clever and subtle God to influence events in ways that are profound, but scientifically undetectable to us. Those events could include the appearance of mutations, the activation of individual neurons in the brain, and even the survival of individual cells and organisms affected by the chance processes of radioactive decay.”

In other words, God is a Mover of Electrons, deliberately keeping his incursions into nature so subtle that they’re invisible. It is baffling that Miller, who comes up with the most technically astute arguments against irreducible complexity, can in the end wind up touting God’s micro-editing of DNA. This argument is in fact identical to that of Michael Behe, the ID advocate against whom Miller testified in the Harrisburg trial. It is another God-of-the-gaps argument, except that this time the gaps are tiny.

Obviously, given that higher intelligence and rationality of the human type has evolved only once, the existence of convergence says nothing about whether these features would always appear.  In fact, the one-offness seems to imply otherwise.

What bothers me about this is, of course, that BioLogos is using the imprimatur of science (and the wonky ideas of Simon Conway Morris) to try to convince people that of course our evolution was inevitable.  This tactic is a favorite of BioLogos (and Templeton), for it tries to blur the boundaries between science and faith.  As scientists we can say nothing about the inevitability of humans except that it seems unlikely given its unique appearance.  Certainly one can say that the idea of evolutionary convergence is irrelevant here.

Please, BioLogos, stop making scientific arguments for God!

BioLogos Foundation’s “suggested reading”

May 10, 2009 • 11:01 am

Francis Collins’s accommodationist website BioLogos, funded by our friends at The Templeton Foundation, features this book prominently on their website:

Lamoreauyx

All well and good, until you get to the publisher’s description:

“In this thought-provoking book, born-again Christian Denis O. Lamoureux argues that the God of the Bible created the universe and life through evolution—an ordained, sustained, and design-reflecting natural process. In other words, evolution is not the result of blind chance and our creation is not a mistake. Lamoureux challenges the popular assumption that God disclosed scientific facts in the opening chapters of Scripture thousands of years before their discovery by modern science. He contends that in the same way the Lord meets us wherever we happen to be in our lives, the Holy Spirit came down to the level of the inspired biblical writers and used their ancient understanding of origins in order to reveal inerrant, life-changing Messages of Faith. Lamoureux also shares his personal story and struggle in coming to terms with evolution and Christianity.”
Wipf and Stock Publishers

Sounds like directed evolution to me: “ordained and design-reflecting”.  This is supported by the thesis of Lamoureux’s earlier book Evolutionary Creation, which is described on his own website as follows:

“Evolutionary creation claims the Father, Son and Holy Spirit created the universe and life through an evolutionary process. This position fully embraces both the religious beliefs of conservative Christianity and the scientific theories of cosmological, geological and biological evolution. It contends that God ordains and sustains the laws of nature, including the mechanisms of evolution. More specifically, evolution is ‘teleological,’ and features plan, purpose and promise. In particular, this view of origins asserts that humanity evolved from primate ancestors, and during this natural process the Image of God arose and sin entered the world. Evolutionary creationists experience God’s presence and action in their lives. They contend that the Lord meets men and women in a personal relationship, which at times involves both dramatic and subtle miraculous signs and wonders.”

Walks and quacks like creationism. . Do Collins and Templeton really want to be in bed with this kind of person?When are Collins and his minions going to realize that this is CREATIONISM and not the theory of evolution as it is is understood by scientists?  An evolutionary process that is guided, and aimed at evolving specific species, is a form of supernaturalism.  Darwin himself recognized this in a letter to the geologist Charles Lyell:

I entirely reject, as in my judgment quite unnecessary, any subsequent addition ‘of new powers and attributes and forces,’ or of any ‘principle of improvement’, except in so far as every character which is naturally selected or preserved is in some way an advantage or improvement, otherwise it would not have been selected. If I were convinced that I required such additions to the theory of natural selection, I would reject it as rubbish. . . I would give absolutely nothing for the theory of Natural Selection, if it requires miraculous additions at any one stage of descent.

Templeton claims it will have no truck with creationism or intelligent design, but that is precisely what is being promoted on BioLogos’s website.   More blurring of the boundaries between faith and science, but of course that is Templeton’s (and Collins’s) agenda.  Dr. Collins is a scientist, and should know better.  And I wish that Templeton would keep its prosperous paws away from evolutionary biology — they always muck it up!


Francis Collins sees God in quantum mechanics

May 7, 2009 • 2:32 pm

Over at New Scientist, Andy Coghlan takes on BioLogos (Francis Collins’s new accommodationist website), and its theistic assertion that God can act through the “uncertainties” in quantum mechanics. (This is also an argument made by Kenneth Miller in Finding Darwin’s God.) Coghlan quotes BioLogos and then dismantles the argument:

“With quantum mechanical uncertainty and the chaotic unpredictability of complex systems,” Collins writes, “the world is now understood to have a certain freedom in its future development.”

This means, he goes on:

“It is thus perfectly possible that God might influence the creation in subtle ways that are unrecognisable to scientific observation. In this way, modern science opens the door to divine action without the need for law-breaking miracles,” says Collins.

“Given the impossibility of absolute prediction or explanation, the laws of nature no longer preclude God’s action in the world. Our perception of the world opens once again to the possibility of divine interaction.”

So, because God somehow tinkers in a quantumy type way, it’s worth praying for divine guidance and intervention. To me, and to other scientists and commentators, Collins is straying into pseudo-scientific speculation simply to keep God in the earthly frame. Believing in God in the first place is by definition a leap of faith, and one that many scientists and many non-scientists are, after careful and reasonable thought, unwilling to take. For those who have trouble accepting that we’re a product of pure chance, there is the option of believing that God set everything in motion.

Larry Moran brings up the same issue over at Sandwalk. This is precisely the problem of strenuous accommodationism as typified by Collins’s website. It just can’t help insinuating itself into real science.  It is embarrassing to see a scientist straying into this kind of territory, and it smacks of desperation.
