A Bit Narrow in Scope but Well Done
Edited by James Beilby Naturalism Defeated is a collection of essays responding to Alvin Plantinga's thesis that human rationality is unlikely in light of purely Naturalistic Evolution (NE), or in other words, if our cognitive faculties developed in an entirely undetermined manner it is unlikely that our reason is reasonable. This argument has been put forth by Plantinga previously in Warrant and Proper Function. I offer the following thoughts for potential readers.

The discussion is structured in a common format for these types of book-length philosophical examinations. Initially, Plantinga provides an overview of his argument. This is followed by a collection of essays discussing and criticizing his thesis. These comments are then followed by Plantinga response to the various contributors. Often in this style of discussion the principle author is allowed to interact individually with each critic. In the present volume, given the number of contributors, a single comprehensive response at the end appears to be the best approach to minimize redundancy.

Plantinga continues to set the stage for much of the discussion within the philosophy of religion and is arguably one the most capable contemporary philosophical thinkers. His handling of the N/E - rationality question is characteristically powerful, clear and clever. Given its sweeping repercussions the perceived success or failure of the various commentators will in significant part be determined by the readers' worldview. For instance some atheists may find Plantinga's contention unpalatable irrespective of its logical and intellectual rigor. Whereas, certain theists may be presupposed to gloss over challenges to Plantinga's proposition. From my perspective despite some overlap amongst the different contributors the essays were generally solid (with perhaps the exception of those by Fodor and Fales). The efforts by Alston and Talbot were particularly note worthy.

Although many interesting definitional and semantic issues were discussed, two interesting points were raised by several of Plantinga's critics. First, the development of reason was as implausible under a theistic construct as it was in an atheist model, and second, the self evidence of rationality boded well for its truth value. The first point which attempts to turn the tables on theists - while an interesting rhetorical move - appears to be still born. Complicated Bayesian probability calculations are not required for most people to recognize that rationality is indeed considerably more likely under a theistic view than a purely NE approach. I agree with the latter point (and I sense Plantinga would also) that reason seems to be an almost unassailable brute fact. As noted by Alston, however, this only serves to shift the arguement to an equally daunting question for the NE supporter. Is NE's probable given its apparent incompatibility with a brute fact such as human reason?

Overall the book is an outstanding work. Comments from a broader range of philisophical positions might have added even more value. Prior exposure to philosophical thought and this argument in particular may make the discussion more fruitful and interesting to the reader.

No shock here
I don't agree with Plantinga, and I found nothing shocking here. What I found is a desperate attempt to justify the irrationality of Christianity. The essence of Plantinga's entire career up to this book has been "If I'm going down, I'm taking you with me." Well, he doesn't succeed. The criticism in the first part of the book alone is enough to permanently debilitate Plantinga's arguments. So much of the alvinizing in the rest of the book turns on varying interpretations of rationality, semantics & syntax, the proper way to measure probabilities, and the best way to construe evolutionary theory. The result is that metaphysical naturalism emerges just fine. For all the certainty his Christianity no doubt provides him, it's interesting to see that the best Plantinga can do against the other side is a sophist's display of clever tricks and dogmatic assertion worthy of P.T. Barnum.

Naturally Irrational
Naturalists are usually seen as paragons of rationality while theists are thought to be at the edge of crazy. Alvin Plantinga's argument challenged this identification questioning even the possibility of holding to Naturalism and trusting the cognitive faculties. This book begins with challenges to the evolutionary argument against naturalism and ends with a response to the challenges by Alvin Plantinga.

The eleven critical essays here are divided into four sections each one dealing with a separate set of objections to the evolutionary argument against naturalism. The argument itself is briefly presented in the beginning and then re-presented even more briefly by each of 'Beilby's cohorts'. There is some repetition in the book, which is not so bad when you're looking for clarification on the most contentious points under discussion.

The main areas of criticism in the book are from Science (Evolution), Skepticism, Conditional Probabilities/Confirmation Theory and the Nature of Epistemic Defeat.

Prior to reading this book I had thought Plantinga's argument was very strong -- so I was basically looking for objections that I was unaware of and answers to those objections; I found a lot of both. If you already agree with Plantinga you will probably find clarification and strengthening of the argument; if you don't already agree, well, then, I don't know what you'll find maybe shock/horror? Actually, most of the book is critical and provides ammunition for dissenters. But, in the end I think the worst that could be said about the argument is that it was 'bloodied but unbowed' (Plantinga).

I found William Alston's comments very helpful -- they suggest a different way of formulating the argument -- something like a Reductio ad Absurdum I think.
