The recent issue of The New Republic contains an essay by Darwinian biologist Jerry Coyne on why he believes there can be no rapprochement between science and "religion." I place the word religion in quotes because it's a slippery term and Coyne never really defines what he means by it. At any rate, over the next several days I'd like to offer a few thoughts on Coyne's column.
He starts off talking about Darwinian evolution, the belief that all life arose through blind, purposeless physical processes:
The ideas that made Darwin's theory so revolutionary are precisely the ones that repel much of religious America, for they imply that, far from having a divinely scripted role in the drama of life, our species is the accidental and contingent result of a purely natural process.
This is an important point, one that's often lost on people. The intellectual conflict today is not between "religion" and evolution. There's no necessary incompatibility between the two, not even between young-earth creationism and evolution (as I hope to point out in a future post). The conflict, rather, is between Darwinian evolution and the belief that an intellect is involved in the creation of the world. Darwinism denies any role for purpose, intention, or mind in the generation and diversification of life and it is this view, which is at bottom a non-scientific, philosophical belief, which many religious people reject.
Coyne goes on to lament that:
[W]hile 74 percent of Americans believe that angels exist, only 25 percent accept that we evolved from apelike ancestors.
Little wonder, actually. Perhaps three out of four people find it easier to believe that angels exist than to believe that a process like the Krebs cycle or the human brain could have evolved by pure, mindless serendipity. How many people have ever studied the question of human evolution - at least subsequent to their high school graduation, at which ceremony their minds are purged of all that they learned over the last couple of years anyway? What reason do most people have at hand for believing that we evolved from apelike ancestors? Should they believe it just because the scientific high priests like Coyne tell them they should? If so, how is that different than the warrant people have for believing, on the authority of their pastors and priests, in angels?
In any event, it's hard to draw any conclusions about the significance of statistics like these. Likewise with this factoid that Coyne serves up:
As Karl Giberson notes in [his book] Saving Darwin, "Most people in America have a neighbor who thinks the Earth is ten thousand years old."
I'm not sure what we should make of this bit of snideness, either. Should we assume that there are a lot of uneducated bumpkins in the world, or are we to conclude that a lot of these young-earthers are so anti-intellectual that they refuse to allow evidence to trump their religion? Probably Coyne intends for us to think both, but refusing to allow evidence to trump one's deepest convictions is not just a fault of the average guy in the neighborhood. There are a lot of educated people who are just as impervious to evidence as Coyne believes young-earthers to be. Among our professoriat, for example, there are many who, despite all the empirical evidence to the contrary, still believe that people are better off under Marxist communism than under any other political-economic system. If we're going to poke fun at beliefs that are at odds with the evidence maybe beliefs for which there is direct empirical refutation should be held in even greater derision than those against which the evidence is more indirect. In any case, Coyne's attempt to discredit American religiosity by associating it with young-earth creationism is no more persuasive than trying to discredit philosophical materialism by associating it with communism.
We begin Part II of our consideration of biologist Jerry Coyne's essay in The New Republic on the incompatibility of science and religion with this passage by Coyne:
True, there are religious scientists and Darwinian churchgoers. But this does not mean that faith and science are compatible, except in the trivial sense that both attitudes can be simultaneously embraced by a single human mind. (It is like saying that marriage and adultery are compatible because some married people are adulterers. )....The real question is whether there is a philosophical incompatibility between religion and science. Does the empirical nature of science contradict the revelatory nature of faith? Are the gaps between them so great that the two institutions must be considered essentially antagonistic?
Science and religion are incompatible, implies Coyne, because science accepts only what can be empirically demonstrated whereas religion admits of truths that are not testable and thus not subject to empirical confirmation. Would that this were true. If it were then there might not be any real conflict since naturalistic scientists would recognize the limits to their domain. As it is, there's conflict for precisely the reason that many scientists wish to extend the realm of science beyond the empirical to encompass all reality and thought, including the metaphysical, while at the same time criticizing religion for making metaphysical claims and being insufficiently scientific. Science serves for many scientists as a kind of Trojan horse that enables them to smuggle into their work and writing a materialistic, atheistic worldview that has no empirical warrant.
A few examples of this overreach may suffice. Scientists, either some or most, hold fast to the following things, none of which are supported by any empirical evidence:
1. The Many Worlds Hypothesis: The idea that ours is just one of a nearly infinite number of universes, all of which are closed off from each other thus defying detection.
2. The Oscillating Universe Hypothesis: The theory that our universe has expanded and collapsed an infinite number of times.
3. String theory: The idea that the fundamental units of material substance are unimaginably tiny vibrating filaments of energy.
4. The existence of other dimensions: The theory that the four dimensions of space-time are only part of physical reality.
5. The Principle of Uniformity: The assumption that the laws and properties of the universe are homogenous and constant everywhere throughout the cosmos.
6. The Assumption of Uniformitarianism: The idea that the same processes and forces at work in the world today have always been at work at essentially the same rates.
7. The Scientific Method: The idea that there is a particular methodology that defines the scientific process and which ought to be followed.
8. The Law of Parsimony: The principle that assumes that the simplest explanation which fits all the facts is the best.
9. The assumption that human reason is trustworthy: The notion that a faculty which has evolved because it made us better fit to survive is also coincidentally a dependable guide to something else, truth, which has no necessary connection to human survival.
10. The assumption that we should value truth: The idea that truth should be esteemed more highly than competing values, like, for instance, personal comfort or group advancement.
11. The assumption that there is objective truth: This is the assumption that there is truth about the world that is independent of our own subjective biases, perceptions, etc.
12. The preference in science for naturalistic explanations: This is a preference based upon an untestable assumption that all knowable truth is found only in the natural realm.
13. Naturalistic abiogenesis: The belief that natural forces are sufficient in themselves to have produced life.
14. The assumption that if something is physically possible and mathematically elegant then, given the age of the universe, it probably happened.
15. The assumption that the cosmos is atelic: I.e. that it has no purpose.
16. The assumption that there's a world external to our own minds.
17. Materialistic reductionism: The conviction that all phenomena, including mental phenomena, can be ultimately explained solely in terms of physics and chemistry.
18. Assumption that the universe arose out of a "vacuum matrix" rather than out of nothing.
19. The appropriateness of making ethical claims regarding the environment, climate change, nuclear power, cloning, or genetic engineering. Ethical judgments lie beyond the scope of science but that doesn't stop scientists, qua scientists, from making them.
20. The Concept of the Meme: According to biologist Richard Dawkins memes are the cultural analog to genes. They are ideas or customs that are believed by Dawkins and others to get passed along according to their survival value rather than their truth value (see #9, above). An example of this, unfortunately, is the concept of the meme itself.
21. The criteria by which we distinguish science from non-science.
All of these transcend the realm of empirical science yet scientists like Coyne doubtless accept most of them. There's nothing wrong with this, of course, it's just that it's a bit disingenuous to claim that scientists confine themselves only to what is testable and empirical, as though scientists were concerned merely with accumulating and compiling facts about nature and not in trying to interpret what those facts mean. As soon as they do try to decipher the meaning of their data, however, they're doing the same thing that religion does, and that's why there's conflict.
There are two competing metanarratives vying for people's allegiance. One claims that nature is all there is and the other claims that nature, by itself, is inadequate to explain all we know about ourselves and the cosmos. Neither metanarrative is scientific, they're both metaphysical. The former seeks to infiltrate the culture under the guise of science, but it goes well beyond the pursuit of empirical knowledge. The naturalist, or materialist, believes that he alone should have the right to determine the meaning of scientific data, but why should he be granted that privilege? Why should an atheistic worldview be awarded supremacy over all competitors?
The role of science is to discover the data, and the role of philosophy is to determine which explanation best conforms to the data we have. Thus the conflict is not between science and religion, but between two disparate philosophical approaches to the data: atheism and theism, naturalism and supernaturalism. In that conflict science, properly understood, is neutral.
In the New Republic column we've been reviewing biologist Jerry Coyne makes some interesting claims about the relationship between science and religion. Some of what he says is helpful and some is not. An example of the latter is this graph:
[A]ll creationists share four traits. First, they devoutly believe in God. No surprise there, except to those who think that ID has a secular basis. Second, they claim that God miraculously intervened in the development of life, either creating every species from scratch or intruding from time to time in an otherwise Darwinian process. Third, they agree that one of these interventions was the creation of humans, who could not have evolved from apelike ancestors. This, of course, reflects the Judeo-Christian view that humans were created in God's image. Fourth, they all adhere to a particular argument called "irreducible complexity." This is the idea that some species, or some features of some species, are too complex to have evolved in a Darwinian manner, and must therefore have been designed by God. Blood clotting in vertebrates, for example, is a complex sequence of enzyme reactions, involving twenty proteins that interact to produce the final clot.
As it happens Coyne is presenting us with a straw man. First, he conflates creationism with ID and then claims that because all creationists believe in God therefore all IDers believe in God. This is false, of course. IDers believe in a designer. Some think the designer is the God of the Bible, but others have no idea who or what it is. It could be an Aristotelian prime mover, a Platonic demiurge, or, for all we know, an inhabitant of one of the infinite worlds posited by multiverse enthusiasts.
Second, Coyne asserts that IDers all believe that God intervened at points in the evolution of life to create various forms, especially man. Some do believe this, of course, but it's simply false to claim that all do. One model of God's creative activity sees God not as an artist doing touch up work on a canvas but more like the bed of a braided river:
Just as the bed guides the flow of water as it splits and wanders toward its destination, so, too, might God underlie the entire process of evolution leading it at every moment in the direction he wants it to flow. In this model, God's intervention is not a one-time or periodic event, but rather a continuous, moment by moment channeling of the flow of evolutionary progress.
Coyne continues:
ID turns out to be simply a "god of the gaps" argument--the view that if we do not yet comprehend a phenomenon completely, we must throw up our hands, stop our research, and praise the Lord. For scientists, that is a prescription for the end of science, for perpetual ignorance.
The problem for Coyne's thesis here is that it's refuted by the fact that people like Galileo, Kepler, Newton, Boyle, Faraday, Maxwell and so many others, ID advocates all, didn't just throw up their hands and say "God did it" and proceed to look for some other line of work. These men spawned the age of science and they all believed exactly what Coyne claims to be fatal to the scientific enterprise: That the world reveals evidence of having been intelligently engineered.
The "god of the gaps" argument is invoked by people who have no explanation for a phenomenon, but modern ID isn't based on what we don't know, its based on what we do know. What we know is that the biosphere is information-rich and that information, whenever we have otherwise encountered it, has always and invariably been the product of intelligence. The information coded in our DNA, for example, or the information on display in something like the Krebs cycle, or biomolecular machines, have their analogs in computer software and hardware and what we know is that these are certainly not artifacts produced by blind, purposeless forces.
Coyne goes on to say:
But no serious scientist wants evolution to become anything like a religion, or even a source of ethics and values. That would mean abandoning our main tool for understanding nature: the resolution of empirical claims with empirical data.
Evidently Coyne hasn't read Richard Dawkins' God Delusion in which Dawkins grounds all of life in an evolutionary worldview. And what's this about resolving empirical claims with empirical data? Where are the data to support the claim that life arose by a purely naturalistic process? Or the claim that consciousness is a purely physical, material phenomenon? Or that this world is one of an infinite number of worlds? Where are the data that show that blind, purposeless chance and natural selection have produced butterfly metamorphosis, or sexual reproduction, or insect flight, or human consciousness?
A lot of people are impressed by the astonishing fine-tuning of cosmic parameters and forces (see here and here) and impute this to intelligent, intentional engineering, but not Coyne. He's committed, we are to understand, only to what the data show. He'll admit only the empirical facts of the matter. So how does he explain cosmic fine-tuning? With empirical data? Alas, he offers us only vague hopes, wishes, and speculative metaphysics:
[S]cientists have other explanations [for the universe's exquisite precision], ones based on reason rather than on faith. Perhaps some day, when we have a "theory of everything" that unifies all the forces of physics, we will see that this theory requires our universe to have the physical constants that we observe. Alternatively, there are intriguing "multiverse" theories that invoke the appearance of many universes, each with different physical laws; and we could have evolved only in one whose laws permit life. The physicist Lee Smolin has suggested a fascinating version of multiverse theory. Drawing a parallel with natural selection among organisms, Smolin proposed that physical constants of universes actually evolve by a type of "cosmological selection" among universes. It turns out that each black hole--and there are millions in our universe--might give rise to a new universe, and these new universes could have physical constants different from those of their ancestors. (This is analogous to mutation in biological evolution.) And universes with physical constants close to the ones we see today happen to be better at producing more black holes, which in turn produce more universes. (This resembles natural selection.) Eventually this process yields a population of universes enriched in those having just the right properties to produce stars (the source of black holes), planets, and life. Smolin's theory immensely raises the odds that life could appear.
When Coyne says there are explanations "based on reason, not faith" what he actually means is that there are explanations based on materialism not on intelligence. After all, he himself is displaying a powerful faith that ultimately a plausible materialist explanation will be found.
In any event, such a theory as he proposes might be true, who knows? But that's the point. There's no empirical evidence for these hypotheses. Our Knight of Faith has tacitly admitted that his belief is based not on empirical facts at all but upon an unshakeable metaphysical faith-committment to naturalism.
Moreover, if there is a multiverse in which all logically possible conditions prevail then there might well be a world in which there dwells a being capable of creating a world like ours. If so, why could not our world represent the creative effort of such a being? In other words, by embracing the concept of the multiverse Coyne refutes his own argument that ID's designer has to be the God of the Bible.
Coyne seems to vaguely realize that he's wandered onto very thin ice and tries to explain why his faith in nature is better than belief in an intelligent agent:
[Belief in] the existence of multiverses does not require a leap of faith nearly as large as that of imagining a God.
This is interesting. He acknowledges that his views are based upon faith, not empirical data, but he justifies taking the "leap" by asserting that his leap is shorter than that of the IDer. How, though, does Coyne measure the size of such leaps? What metric does he use? Are such leaps subject to empirical quantification? Coyne thinks that the breath-taking precision of dozens of cosmic properties is easier to impute to the existence of a near infinity of contingent worlds, all having different constants and forces, none of which we have any evidence for, and whose origin itself would stand in need of an explanation, than it is to attribute it to the existence of a singular intelligence whose existence is not contingent upon anything. How does Coyne decide that the latter requires a greater leap of faith than the former?
And some scientific explanations of the anthropic principle are testable. Indeed, a few predictions of Smolin's theory have already been confirmed, adding to its credibility. It may be wrong, but wait a decade and we will know a lot more about the anthropic principle. In the meantime, it is simply wrong to claim that proposing a provisional and testable scientific hypothesis--not a "belief"--is equivalent to religious faith.
This is what the materialist usually winds up saying: "Wait a decade." He insists that empirical claims must be resolved with empirical data, but if the empirical data is lacking, materialist conclusions are drawn anyway. They're simply backed by a promissory note: "Just wait," the materialist urges. "Someday the empirical evidence will arrive, but in the meantime you must have faith that they will." This sounds very much like secular eschatology.
At any rate, if ID believes in a "God of the gaps" then materialism believes in a god of the promises. What Coyne apparently meant by resolving empirical claims with empirical data was that empirical claims must be resolved with empirical data or by nebulous promises of such data appearing in the future. Meanwhile, we are commanded to just believe and not question our scientific bishops.
Coyne set out to argue that religion and science are incompatible because they have different doxastic criteria (justifications for belief). It may be true that the claims of each require different sorts of warrant but that hardly makes them incompatible. Where, for example, is the conflict between the claim that birds migrate by the stars and the claim that God exists? Where's the incongruity between the belief that the universe is comprised mostly of dark matter and energy and the belief that an omnipotent, omniscient and personal God created it?
The incompatibility is not between religious belief and science but between religious belief and materialism. Materialism, however, is metaphysics, not science, and Coyne's tendency to conflate the two is ironic as we'll point out in the last paragraph.
Coyne writes:
In a common error, [Karl] Giberson confuses the strategic materialism of science with an absolute commitment to a philosophy of materialism. He claims that "if the face of Jesus appeared on Mount Rushmore with God's name signed underneath, geologists would still have to explain this curious phenomenon as an improbable byproduct of erosion and tectonics." Nonsense. There are so many phenomena that would raise the specter of God or other supernatural forces: faith healers could restore lost vision, the cancers of only good people could go into remission, the dead could return to life, we could find meaningful DNA sequences that could have been placed in our genome only by an intelligent agent, angels could appear in the sky. The fact that no such things have ever been scientifically documented gives us added confidence that we are right to stick with natural explanations for nature. And it explains why so many scientists, who have learned to disregard God as an explanation, have also discarded him as a possibility.
This is hard to follow. Coyne seems to want to say that the materialistic assumptions scientists employ are just a methodological tactic, but he winds up endorsing a kind of materialistic metanarrative. Moreover, the notion that the experience of certain phenomena would jar scientists out of their materialism hardly proves that their materialism is merely tactical. If it's true that scientists could be persuaded by empirical evidence to jettison their materialism it only means that they're open-minded and rational.
Even so, I think Coyne is mistaken about this. If any of the phenomena he mentions actually occurred, a materialist would immediately, and rightly, set about looking for a mechanical, natural explanation. If his search were unsuccessful he'd simply issue a promissory note and assure us that science will surely discover the causal mechanisms behind the phenomena eventually. Angels in the sky would be explained away as either mass hallucination events or the visitation of life-forms from other planets. Even were a DNA sequence or star pattern found that somehow spelled out "I, God, Made This" the materialist would simply shrug and say something like, "Given an infinity of worlds there has to be at least one where such an amazingly improbable pattern would exist." The point is that someone who doesn't want to believe in God will withhold belief as long as there is an "out" through which they can escape. Coyne is being a little naive if he thinks that materialist scientists could be persuaded to abandon their worldview so easily.
He goes on to say that:
Like Giberson, [biologist Ken] Miller rejects a literal interpretation of the Bible. After discussing the fossil record, he contends that "a literal reading of the Genesis story is simply not scientifically valid," concluding that "theology does not and cannot pretend to be scientific, but it can require of itself that it be consistent with science and conversant with it." But this leads to a conundrum. Why reject the story of creation and Noah's Ark because we know that animals evolved, but nevertheless accept the reality of the virgin birth and resurrection of Christ, which are equally at odds with science? After all, biological research suggests the impossibility of human females reproducing asexually, or of anyone reawakening three days after death.
Coyne raises an interesting question here, but muddies it up by seriously misrepresenting science. Science emphatically does not suggest that miracles are impossible. Science deals in probabilities, not possibilities. Indeed, there's very little that science declares impossible. The most science can "say" is that as far as any scientist has ever been able to observe under laboratory conditions, human virgins have never produced offspring and dead people have never revivified. Science qua science cannot say neither of these ever happened nor that they never could happen. Miracles are statistically improbable, they're not logically impossible.
Coyne really seems to be saying something like this: If materialism is true, miracles performed by a supernatural being are impossible. Materialism is true, therefore miracles are impossible. But if this is his argument it's not very persuasive since the truth of the second premise is very much open to dispute. The second premise is, in fact, a religious assumption about the world, as Roy Clouser points out, and it undergirds Coyne's science. This is ironic, as we said above, since Coyne is arguing in this essay that religion and science are incompatible even as he himself has no trouble harmonizing the two in his own life.
Coyne observes in his piece that:
Beginning with Plato, philosophers have argued convincingly that our ethics come not from religion, but from a secular morality that develops in intelligent, socially interacting creatures, and is simply inserted into religion for convenient citation.
With all due respect to Professor Coyne, the term "secular morality" is gibberish. There can be no secular morality except insofar as a group of people arbitrarily agree upon certain rules that have no basis in anything other than the subjective preferences of the people who agree to them. There's no reason to think that a morality so arrived at imposes any kind of obligation upon anyone and there's no reason to feel guilt if one breaks the rules. Only morality grounded in something transcendent can obligate us. So far from secular morality being inserted into religion, it actually piggy-backs on religion, claiming itself to be independent but all the while relying on religion to carry it and give it credibility.
He continues:
In the end, then, there is a fundamental distinction between scientific truths and religious truths, however you construe them. The difference rests on how you answer one question: how would I know if I were wrong? Darwin's colleague Thomas Huxley remarked that "science is organized common sense where many a beautiful theory was killed by an ugly fact." As with any scientific theory, there are potentially many ugly facts that could kill Darwinism. Two of these would be the presence of human fossils and dinosaur fossils side by side, and the existence of adaptations in one species that benefit only a different species. Since no such facts have ever appeared, we continue to accept evolution as true. Religious beliefs, on the other hand, are immune to ugly facts. Indeed, they are maintained in the face of ugly facts, such as the impotence of prayer.
I doubt very much that Darwinians would be dissuaded by the discovery of any of the things Coyne mentions. All such discoveries would do would be to inspire the true-believers to become more creative with their hypotheses. If human fossils were found together with dinosaur fossils then we would read about the possible mixing of rock strata or the surprising survival of dinosaurs long after they had previously been thought to have gone extinct. The Darwinist metanarrative certainly wouldn't be falsified by such finds, only a particular part of the overall theory would be considered in need of an adjustment.
But let's apply Coyne's "How would we know we were wrong" test to Darwinian beliefs about the origin of life. How would we know that life did not arise through blind, impersonal forces if, in fact, it did not? What "ugly fact" would falsify the claim that life is the product of those blind, impersonal forces? No one can offer a candidate, but Darwinian materialists nevertheless continue to insist that their speculations on the matter are scientific. Since no discovery could possibly falsify their belief that life arose purely mechanistically must we not disqualify such beliefs about abiogenesis from the domain of science?
Professor Coyne adds this:
There is no way to adjudicate between conflicting religious truths as we can between competing scientific explanations. Most scientists can tell you what observations would convince them of God's existence, but I have never met a religious person who could tell me what would disprove it. And what could possibly convince people to abandon their belief that the deity is, as Giberson asserts, good, loving, and just? If the Holocaust cannot do it, then nothing will.
I'm not sure what this is supposed to demonstrate other than that religious faith is not the same sort of thing as empirical science, but then nobody said that it was. Coyne is comparing apples and oranges. All anyone he has quoted in his article has said is that science and religion are compatible, not that they're identical. The appropriate comparison is between theistic belief and materialism. The very same phenomena that would falsify materialism, an unmistakable appearance by God, say, would serve to verify theism. On the other hand, if theistic belief cannot be falsified that simply means that materialism cannot be verified. So given this epistemic symmetry why does Coyne believe so adamantly that a scientist can consistently be a materialist but not a theist? How is a scientist's materialism any more compatible with his practice of science than would be his theism? They're both theological.
To be sure, particular religious beliefs may be incompatible with certain scientific beliefs, just as contrary scientific beliefs can be incompatible with each other, but it's one thing to say that a particular tenet of religion is incompatible with a tenet of science, it's quite another to say, as Coyne does, that religious belief is incompatible with science.
