Every so often an article comes along which triggers a firestorm of debate, and the latest is by Jerry Coyne in The New Republic. He reviews two new books by Giberson and Miller, each of which tries to defend the thesis that science and religion are wholly compatible. Coyne disagrees, fundamentally.
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. 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.
Coyne’s essay provoked a series of responses over at the Edge. These included Lisa Randall’s cognitively dissonant experience:
By sheer coincidence the day I read this Edge question, a charming young actor sat next to me on my plane to LA and without any prompting answered it for me.[…] Prior to his acting career he had studied molecular biology and after graduating coordinated science teaching for three middle schools in an urban school system. He described how along with his acting career he would ultimately like to build on his training to start schools worldwide where students can get good science training.
[…]
But he himself believes in Man descending from Adam as opposed to ascending from apes. I didn’t get how someone trained as a biologist could not believe in evolution. He explained how he could learn the science and understand the logic but that it is simply how Man puts things together. In his mind that’s just not the way it is.
I was going to respond in my own words, but then I read Timothy Sandefur’s excellent piece which said everything that I would want to say, and more. Here is his excellent refutation of Ken Miller’s response in Edge:
Then there is Miller himself, who insists once more on his right to have his reason and eat it too. “What science does require is methodological naturalism,†he writes. But why does it require that? That commitment is not an arbitrary postulate—it is an epistemological position, imposed on us by the nature of knowledge and of reality. Miller recognizes this when he acknowledges that “[w]e live in a material world, and we use the materials of nature to study the way nature works.†But of course he then flies to a higher strain—by assuming, without any evidence, that there is some other kind of world in which we also live (a world which, if it is immaterial, by definition has no interaction with our own and would therefore be inaccessible to our knowledge). He, arbitrarily and without foundation, asserts that there is some other world, which he arbitrarily and without foundation asserts can be known by some other method—a method which he arbitrarily and without foundation asserts is religious knowledge. These are three separate assertions about reality which he is willing to endorse not only without reasons, but without even acknowledging the need for reasons. And this he amazingly calls “honest and open empiricismâ€!
