Dawkins vs. Collins (Obama’s New NIH Selection)

RichardDawkins.net has reprinted a 2006 debate between Richard Dawkins and Francis Collins, the prominent (and now powerful) proponent of compatibility between religion and science who has recently been selected by Obama to head up the NIH.  The article has some really interesting moments, so I recommend you read it in full.  Here is what I found to be the most salient exchange, followed by a clip of Dawkins discussing Collins on Bill Maher more recently.

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.”

COLLINS: Certainly science should continue to see whether we can find evidence for multiverses that might explain why our own universe seems to be so finely tuned. But I do object to the assumption that anything that might be outside of nature is ruled out of the conversation. That’s an impoverished view of the kinds of questions we humans can ask, such as “Why am I here?”, “What happens after we die?”, “Is there a God?” If you refuse to acknowledge their appropriateness, you end up with a zero probability of God after examining the natural world because it doesn’t convince you on a proof basis. But if your mind is open about whether God might exist, you can point to aspects of the universe that are consistent with that conclusion.

DAWKINS: To me, the right approach is to say we are profoundly ignorant of these matters. We need to work on them. But to suddenly say the answer is God–it’s that that seems to me to close off the discussion.

TIME: Could the answer be God?

DAWKINS: There could be something incredibly grand and incomprehensible and beyond our present understanding.

COLLINS: That’s God.

DAWKINS: Yes. But it could be any of a billion Gods. It could be God of the Martians or of the inhabitants of Alpha Centauri. The chance of its being a particular God, Yahweh, the God of Jesus, is vanishingly small–at the least, the onus is on you to demonstrate why you think that’s the case.

Another highlight of the interview  is their debate about evolution, God, and the origins of altruism, so be sure to click on the link and read through the entire exchange, paying attention to that portion in particular.  In the meantime, passively enjoy this video interview of Dawkins by Maher:
