Once again, science is a method. It’s a general set of procedures that rest on skepticism, induction, empiricism, and naturalism. Atheism is a conclusion. We look at the universe using the tools of science, and it does not fit any description of the universe derived from religious perspectives: we therefore reject religious dogma. We also see that the nature of the universe does not reflect any of the orthodox conceptions of what a god-ruled universe would look like. We arrive at the conclusion that there is no god.
Science=method. Atheism=conclusion. They’re different.
I have a lot of sympathy with this argument, but with substantial reservations.
I agree with the argument this far: if you assembled a team of neutral observers to take a scientific approach to the question of the existence of God, looking at all the evidence and considering different hypotheses to explain it, I think they would reject the God hypothesis. Absence of evidence is not proof, but it certainly leaves you with a very weak case.
But still… I’m uncomfortable with saying that atheism is the conclusion reached by the scientific method. I guess the reason is this. When someone says ‘Science tells us [something]’, they are claiming a certain kind of authority for that idea. That authority has been painstakingly acquired over a couple of centuries via the slow, methodical, rigorous accumulation of data and the testing of ideas. It comes from millions of man-hours spent observing nature, collecting and classifying specimens, and devising and implementing experiments.
So a statement like ‘humans are descended from apes’ can be backed up carefully and in detail on the basis of the fossil record, comparative physiology and genetics. There are, presumably, thousands of peer-reviewed scientific papers discussing the idea. One could make similarly scientific statements about the chemical composition of tears, the weight of the electron, and thousands of other subjects.
‘There is no God’ is not, it seems to me, a scientific statement in the same way as ‘humans are descended from apes’. Most scientists may believe it to be true, and may believe that it is the conclusion most consistent with a scientific view of the world, but that doesn’t mean that it is a product of science.
The public authority of science—the willingness of people to accept what scientists say—is already probably less than it was a few decades ago, having been attacked by a peculiar combination of the religious, New Agers, alternative medicine and cultural relativists. But it is still high. What scientists say carries weight. That authority should be valued, and not invoked lightly. When a professional scientist like P.Z. Myers says that atheism is the result of science, it seems to me he is claiming that cultural authority inappropriately, and risks weakening it.
Myers rightly makes fun of the proponents of Intelligent Design for pretending to be doing science when they’re not, and frequently points out their complete lack of published scientific papers. He rightly sees that they are trying to appear to be scientific in part because they are trying to take some of the cultural authority of science for themselves. They know that if they can convince people they are scientific they will be taken more seriously. But it seems to me that he risks doing the same thing: invoking spurious authority.
