I’ve just read a brief and remarkably persuasive philosophical paper by Tomas Bogardus, a professor of philosophy at Pepperdine University. In it, he argues that, if we are to have confidence in the explanatory power of science (and he believes we should), then the naturalistic worldview must be false.
Here is the abstract:
I begin by retracing an argument from Aristotle for final causes in science. Then, I advance this ancient thought, and defend an argument for a stronger conclusion: that no scientific explanation can succeed, if Naturalism is true. The argument goes like this: (1) Any scientific explanation can be successful only if it crucially involves a natural regularity. Next, I argue that (2) any explanation can be successful only if it crucially involves no element that calls out for explanation but lacks one. From (1) and (2) it follows that (3) a scientific explanation can be successful only if it crucially involves a natural regularity, and this regularity does not call out for explanation while lacking
one. I then argue that (4) if Naturalism is true, then every natural regularity calls out for explanation but lacks one. From (3) and (4) it follows that (5) if Naturalism is true, then no scientific explanation can be successful. If you believe that scientific explanation can be (indeed, often has been) successful, as I do, then this is a reason to reject Naturalism.Keywords: philosophy of religion; philosophy of science; scientific explanation; naturalism; supernaturalism; theism; atheism
The gist of the argument is that science, which is in the business of explaining observable phenomena, must offer for every explanandum (i.e., that which is to be explained) some explanans (that which explains). But if the explanans itself requires explaining, the explanation is incomplete, and must rest upon some deeper explanans.
Bogardus’s paper explores the varieties of possible explanatory regression. Either a) we bottom out on a “brute fact”, or b) we encounter an infinite stack of explanations (“turtles all the way down”), or c) our explanations loop back on themselves (so that at some point every explanandum also becomes an explanans), or d) we come at last to some explanans that breaks the chain, by requiring no further explanation.
Bogardus argues that brute facts, infinite regressions, and circular explanations explain nothing; the only kind of thing that will serve is d). But the “laws of nature” do not meet this requirement, because they do not (and cannot) explain themselves.
The heart of Bogardus’s argument, then, is that only some sort of necessary truth, some teleological principle that stands outside of the chain of scientific explanation, can serve as the anchor to which that chain must be fastened. And because Naturalism admits of no such entity, then if scientific explanations are to be considered valid, Naturalism must be false.
