Any bright high school student can see the flaws in a few minutes. In this way, it functions as a sort of intelligence test for the philosophically inclined. The fact that some philosophers actually took the argument seriously and a few collaborated on a volume entitled Naturalism Defeated? illustrates the sad state of modern philosophy. It's the philosophical equivalent of taking a bogus proof that 2 = 1 and writing an entire book explaining why it is wrong. Yes, you can do it, but why bother?
So guess who accepts it and thinks it is "obviously valid"? Why, that paragon of ignorance and arrogance, Michael Egnor.
It's not surprising, since commenters at his site have tried over and over again to explain to Egnor what the theory of evolution says, but he just can't get it.
