Libertarian economist Bob Murphy forays into the realm of scientific/philosophical controversy to put the kibosh on some of the more common objections to Intelligent Design. He does a pretty good job and says some very interesting things along the way.
For example, he observes that:
[The critics claim that] beyond being merely wrong, ID allegedly fails to qualify even as a scientific theory at all. Science invokes only natural causes to explain things in the natural world, and hence (the objection runs) ID is unscientific when it invokes an unseen "designer" to explain, say, the irreducible complexity of the human nervous system.
William Dembski has dealt this objection a decisive blow when he explains the potential for ID in bioterrorism forensics. At some point in the not too distant future, we will probably see outbreaks of genetically engineered viruses or bacteria. After a given outbreak, people will need to be able to determine whether the deaths were due to natural causes, or were instead homicides. Now whom should we ask to perform this task for us? Priests? Philosophers? Or scientists? And if you agree that it should be the scientists who figure it out, how should they proceed? Wouldn't they, oh I don't know, take samples of the viruses and see if they could've been produced by Darwinian processes, and then (if not) report to the government that we've got some terrorists out there designing killer microbes?
I think that even the atheist who carries this thought experiment out will have to concede that the counterterrorism analysts will end up doing things that Behe and Dembski talk about right now. Note that I'm not saying the government will hire Behe and Dembski to do it; maybe they're not very good scientists after all. But their work is not in principle unscientific, unless we admit that scientists would have nothing to say in the autopsies of entire towns wiped out by a mysterious virus.
Later he notes that those who argue against creationism by insisting that God would never create something just to have it go extinct must, if they're consistent, be atheists:
I want to reiterate a point I've made elsewhere: If you think that creationism (which isn't the same as ID, by the way) can be ruled out on theological grounds, then (if you believe in the standard theory of evolution) you have to be a virtual atheist. For if no benevolent God would ever (say) specially create millions of different species such that the vast majority would go extinct, then no benevolent God would set up the initial conditions of the universe such that random mutation and natural selection would lead to the evolution and extinction of 99% of all species. In other words, if you think that the history of life rules out the Genesis account, be prepared for it to rule out any account involving a God who is powerful, benevolent, and wise.
He finishes by addressing the claim, iterated and reiterated by Judge Jones in his Kitzmiller decision, that ID is just a disguised form of Christianity:
A very popular (and ad hominem) attack is that ID proponents don't really just believe in ID; they're actually Bible-thumping Christians who pretend they don't know anything about the designer in order to keep the classroom textbooks legal. I agree that the vast majority of ID proponents probably fit this description. However, one notable exception is philosopher Antony Flew. When Flew renounced his atheism because of the evidence of design, I recall prominent atheists reassuring their followers that Flew wasn't a Christian, and that all he meant was that life didn't arise purely by accident. So apparently (as even the atheists in this case point out with relief) one can be convinced by the empirical evidence that life exhibits design, without endorsing the God of the Bible.
Murphy is a layman and some might scoff that he's unqualified to pass judgment on the arguments he critiques, but then Judge Jones is a layman who spent the seven years before his appointment to the federal bench as the chairman of the state liquor control board (hardly a scientific think tank), yet the anti-ID folks seem unable to praise his Solomonic wisdom highly enough.
