A while back, Stephen Colbert had biologist Ken Miller, who teaches at my alma mater (although I never took a class with him), on his show to talk about evolution and intelligent design. Miller is known for being a devout Catholic who supports the scientific consensus of contemporary evolutionary theory. It's a a strange interview. One of Miller's main points is that people who deny evolution can't explain why we need flu shots every year, since the flu virus evolves to the point that old vaccines won't cut it. This is, of course, a terrible straw man argument, because even the most vehement critics of evolution don't deny evolution within a species, what they call microevolution.
But one argument struck me as particularly strange. Miller seems to think waste is a problem for intelligent design, since God designed things that went extinct. Oops! Fossils show God's mistakes. Miller thinks he has a higher view. God set in motion a process that gave rise to everything on this planet, and it shows God's greatness that he used evolutionary processes. So he has a theological reason for favoring the non-ID model.
But wait a minute. Doesn't the theistic evolution model have the same problem? Aren't there all these things that resulted from the process that God initiated that got left behind? If God set in motion the processes that lead to evolution of more complex species, you still get species that result from that process that die out. You get waste. Did God intend that result? If so, then the same problem arises for Miller. Something God designed died out. If not, then we seem to have a denial of God's purposes in creation. Is this the idea common in deism that God sort of set things up but didn't concern himself with the details of how it turned out? That's not very Catholic of Miller, who claims to be a pious, orthodox Catholic. But those seem to be his only options. Either there are forms that were designed by God that no longer exist, or those forms were not designed by God and do not fall under his plan of providence.
So it turns out that this is really an argument against theism and a doctrine of providence, not an argument against intelligent design. This is just puzzling. I don't know Miller's views on providence, but it seems to me that his argument is misdirected either way it turns out, and it should apply as well to any theistic evolutionary view that holds to the theological positions of the Roman Catholic Church. It's really just a particular case of the problem of evil, and I don't really know his views on that issue either. But whatever else is true, this isn't a problem for ID any more than it is for theistic evolution.
Update: Check out the excellent comments on Ted Poston's Prosblogion post on this subject. I'm in full agreement with almost all of the comments to this point (7:42 EST Aug 1, 2007), and some of them are making some of the points I wanted to make in this post but in a much better way. There are also some considerations there that hadn't occurred to me at all but seem right.
