Time Cover Story: Science v Religion
Posted: Mon Nov 06, 2006 12:20 am
There are two great debates under the broad heading of Science vs. God. The more familiar over the past few years is the narrower of the two: Can Darwinian evolution withstand the criticisms of Christians who believe that it contradicts the creation account in the Book of Genesis? In recent years, creationism took on new currency as the spiritual progenitor of "intelligent design" (I.D.), a scientifically worded attempt to show that blanks in the evolutionary narrative are more meaningful than its very convincing totality. I.D. lost some of its journalistic heat last December when a federal judge dismissed it as pseudoscience unsuitable for teaching in Pennsylvania schools.
But in fact creationism and I.D. are intimately related to a larger unresolved question, in which the aggressor's role is reversed: Can religion stand up to the progress of science? This debate long predates Darwin, but the antireligion position is being promoted with increasing insistence by scientists angered by intelligent design and excited, perhaps intoxicated, by their disciplines' increasing ability to map, quantify and change the nature of human experience. Brain imaging illustrates--in color!--the physical seat of the will and the passions, challenging the religious concept of a soul independent of glands and gristle. Brain chemists track imbalances that could account for the ecstatic states of visionary saints or, some suggest, of Jesus. Like Freudianism before it, the field of evolutionary psychology generates theories of altruism and even of religion that do not include God. Something called the multiverse hypothesis in cosmology speculates that ours may be but one in a cascade of universes, suddenly bettering the odds that life could have cropped up here accidentally, without divine intervention. (If the probabilities were 1 in a billion, and you've got 300 billion universes, why not?)
...And to balance formidable standard bearers like Dawkins, we seek those who possess religious conviction but also scientific achievements to credibly argue the widespread hope that science and God are in harmony--that, indeed, science is of God.
Informed conciliators have recently become more vocal. Stanford University biologist Joan Roughgarden has just come out with Evolution and Christian Faith, which provides what she calls a "strong Christian defense" of evolutionary biology, illustrating the discipline's major concepts with biblical passages. Entomologist Edward O. Wilson, a famous skeptic of standard faith, has written The Creation: An Appeal to Save Life on Earth, urging believers and non-believers to unite over conservation. But foremost of those arguing for common ground is Francis Collins.
He is also a forthright Christian who converted from atheism at age 27 and now finds time to advise young evangelical scientists on how to declare their faith in science's largely agnostic upper reaches. His summer best seller, The Language of God: A Scientist Presents Evidence for Belief (Free Press), laid out some of the arguments he brought to bear in the 90-minute debate TIME arranged between Dawkins and Collins in our offices at the Time & Life Building in New York City on Sept. 30. Some excerpts from their spirited exchange:
TIME: Professor Dawkins, if one truly understands science, is God then a delusion, as your book title suggests?
DAWKINS: The question of whether there exists a supernatural creator, a God, is one of the most important that we have to answer. I think that it is a scientific question. My answer is no.
TIME: Dr. Collins, you believe that science is compatible with Christian faith.
COLLINS: Yes. God's existence is either true or not. But calling it a scientific question implies that the tools of science can provide the answer. From my perspective, God cannot be completely contained within nature, and therefore God's existence is outside of science's ability to really weigh in.
TIME: Stephen Jay Gould, a Harvard paleontologist, famously argued that religion and science can coexist, because they occupy separate, airtight boxes. You both seem to disagree.
COLLINS: Gould sets up an artificial wall between the two worldviews that doesn't exist in my life. Because I do believe in God's creative power in having brought it all into being in the first place, I find that studying the natural world is an opportunity to observe the majesty, the elegance, the intricacy of God's creation.
DAWKINS: I think that Gould's separate compartments was a purely political ploy to win middle-of-the-road religious people to the science camp. But it's a very empty idea. There are plenty of places where religion does not keep off the scientific turf. Any belief in miracles is flat contradictory not just to the facts of science but to the spirit of science.
TIME: Professor Dawkins, you think Darwin's theory of evolution does more than simply contradict the Genesis story.
DAWKINS: Yes. For centuries the most powerful argument for God's existence from the physical world was the so-called argument from design: Living things are so beautiful and elegant and so apparently purposeful, they could only have been made by an intelligent designer. But Darwin provided a simpler explanation. His way is a gradual, incremental improvement starting from very simple beginnings and working up step by tiny incremental step to more complexity, more elegance, more adaptive perfection. Each step is not too improbable for us to countenance, but when you add them up cumulatively over millions of years, you get these monsters of improbability, like the human brain and the rain forest. It should warn us against ever again assuming that because something is complicated, God must have done it.
COLLINS: I don't see that Professor Dawkins' basic account of evolution is incompatible with God's having designed it.
TIME: When would this have occurred?
COLLINS: By being outside of nature, God is also outside of space and time. Hence, at the moment of the creation of the universe, God could also have activated evolution, with full knowledge of how it would turn out, perhaps even including our having this conversation. The idea that he could both foresee the future and also give us spirit and free will to carry out our own desires becomes entirely acceptable.
DAWKINS: I think that's a tremendous cop-out. If God wanted to create life and create humans, it would be slightly odd that he should choose the extraordinarily roundabout way of waiting for 10 billion years before life got started and then waiting for another 4 billion years until you got human beings capable of worshipping and sinning and all the other things religious people are interested in.
COLLINS: Who are we to say that that was an odd way to do it? I don't think that it is God's purpose to make his intention absolutely obvious to us. If it suits him to be a deity that we must seek without being forced to, would it not have been sensible for him to use the mechanism of evolution without posting obvious road signs to reveal his role in creation?
TIME: Both your books suggest that if the universal constants, the six or more characteristics of our universe, had varied at all, it would have made life impossible. Dr. Collins, can you provide an example?
COLLINS: The gravitational constant, if it were off by one part in a hundred million million, then the expansion of the universe after the Big Bang would not have occurred in the fashion that was necessary for life to occur. When you look at that evidence, it is very difficult to adopt the view that this was just chance. But if you are willing to consider the possibility of a designer, this becomes a rather plausible explanation for what is otherwise an exceedingly improbable event--namely, our existence.
DAWKINS: People who believe in God conclude there must have been a divine knob twiddler who twiddled the knobs of these half-dozen constants to get them exactly right. The problem is that this says, because something is vastly improbable, we need a God to explain it. But that God himself would be even more improbable. Physicists have come up with other explanations. One is to say that these six constants are not free to vary. Some unified theory will eventually show that they are as locked in as the circumference and the diameter of a circle. That reduces the odds of them all independently just happening to fit the bill. The other way is the multiverse way. That says that maybe the universe we are in is one of a very large number of universes. The vast majority will not contain life because they have the wrong gravitational constant or the wrong this constant or that constant. But as the number of universes climbs, the odds mount that a tiny minority of universes will have the right fine-tuning.
COLLINS: This is an interesting choice. Barring a theoretical resolution, which I think is unlikely, you either have to say there are zillions of parallel universes out there that we can't observe at present or you have to say there was a plan. I actually find the argument of the existence of a God who did the planning more compelling than the bubbling of all these multiverses. So Occam's razor--Occam says you should choose the explanation that is most simple and straightforward--leads me more to believe in God than in the multiverse, which seems quite a stretch of the imagination.
DAWKINS: I accept that there may be things far grander and more incomprehensible than we can possibly imagine. What I can't understand is why you invoke improbability and yet you will not admit that you're shooting yourself in the foot by postulating something just as improbable, magicking into existence the word God.
COLLINS: My God is not improbable to me. He has no need of a creation story for himself or to be fine-tuned by something else. God is the answer to all of those "How must it have come to be" questions.
DAWKINS: I think that's the mother and father of all cop-outs. It's an honest scientific quest to discover where this apparent improbability comes from. Now Dr. Collins says, "Well, God did it. And God needs no explanation because God is outside all this." Well, what an incredible evasion of the responsibility to explain. Scientists don't do that. Scientists say, "We're working on it. We're struggling to understand."
[closing remarks]
COLLINS: I just would like to say that over more than a quarter-century as a scientist and a believer, I find absolutely nothing in conflict between agreeing with Richard in practically all of his conclusions about the natural world, and also saying that I am still able to accept and embrace the possibility that there are answers that science isn't able to provide about the natural world--the questions about why instead of the questions about how. I'm interested in the whys. I find many of those answers in the spiritual realm. That in no way compromises my ability to think rigorously as a scientist.
DAWKINS: My mind is not closed, as you have occasionally suggested, Francis. My mind is open to the most wonderful range of future possibilities, which I cannot even dream about, nor can you, nor can anybody else. What I am skeptical about is the idea that whatever wonderful revelation does come in the science of the future, it will turn out to be one of the particular historical religions that people happen to have dreamed up. When we started out and we were talking about the origins of the universe and the physical constants, I provided what I thought were cogent arguments against a supernatural intelligent designer. But it does seem to me to be a worthy idea. Refutable--but nevertheless grand and big enough to be worthy of respect. I don't see the Olympian gods or Jesus coming down and dying on the Cross as worthy of that grandeur. They strike me as parochial. If there is a God, it's going to be a whole lot bigger and a whole lot more incomprehensible than anything that any theologian of any religion has ever proposed.
