God vs. Science

We revere faith and scientific progress, hunger for miracles and for MRIs. But are the worldviews compatible? TIME convenes a debate

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.
