Plantinga gave a devastating argument against the conjunction of naturalism and evolution to the effect that that belief supplies the reflective naturalist with a defeater for all his beliefs in his WPF book, and then expanded on it in his WCB book. He also wrote some papers that eventually made it to the web, or were picked up by various journals. So why is any intellectually honest person still a naturalist who believes in evolution? Well, some people actually didn't think Plantinga's argument cut it! Shocking, I know. So, they too wrote about it in books, and had papers published in various journals. In fact, not only did evolutionary naturalists critique the argument, but so did some theistic philosophers. Given all the potential here for serious philosophical debate, and finally a fair fight with 50 (or so) against the mind of Plantinga(!), a book had to be made with critiques and then responses to the critiques. Well, enter Naturalism Defeated: Essays on Plantinga's Evolutionary Argument Against Naturalism. If you like Plantinga's argument and you use it, you need this book so you can be aware of the critiques. If you dislike the argument, you need Plantinga's rebuttals to the critiques to show you that you're wrong! :-) At the end of the day, as you can probably tell, I side with Plantinga. As Plantinga says: "I should say up front, however, that EAAN seems to me to emerge unscathed--or if a bit scathed, then at least bloody but unbowed." Yes, that nicely sums up the book.
