In his recently published Where the Conflict Really Lies: Science, Religion, & Naturalism 2011 Alvin Plantinga criticises Paul Draper’s evolutionary argument against theism as part of a larger project to show that evolution poses no threat to Christian belief. Plantinga focuses upon Draper’s probabilistic claim that the facts of evolution are much more probable on naturalism than on theism, and with regard to that claim makes two specific points. First, Draper’s probabilistic claim contradicts theism’s necessary falsehood; unless Draper wishes to (...) acknowledge that theism is necessarily true, his claim commits him to theism’s contingency and so sets him at odds with a mainstream that sees God’s existence as decidedly noncontingent. Second, Plantinga argues that Draper’s probabilistic claim is, even if true, overwhelmed by counterclaims about facts that are more likely on theism than naturalism. I argue this critique of Draper depends upon a serious error, and that Plantinga overlooks the full implications of his own presuppositions. Correcting these shortcomings shows that Plantinga’s own probabilistic-apologetics (e.g., the ‘Evolutionary Argument Against Naturalism’) requires theism’s contingency no less than does Draper’s atheology.

The penultimate chapter of Alvin Plantinga's "Warrant and Proper Function" attacks metaphysical naturalism through an argument which concludes that only a supernaturalistic worldview can accommodate the indispensable concept of proper function. I make the case that this argument, which I dub 'the argument from proper function', suffers from two major flaws. First, it underestimates the naturalist's ability to ground natural proper function ascriptions in the concept of health. Second, it relies upon an overly stringent standard for successful conceptual analysis; ironically, (...) the naturalist can undercut the argument by adopting Plantinga's own recommended model for analysing concepts.

Alvin Plantinga’s Warranted Christian Belief (2000) is the capstone to the latest stage in his views on the intellectual credibility of theism in general, and Christian theism in particular. While Plantinga’s stature in the community of Christian philosophers alone makes gaining familiarity with this text a good idea for contemporary analytic philosophers of religion, its vigorous, innovative defense of specifically Christian theism and daring suggestions for renovating the landscape of analytic philosophy of religion merit serious consideration. I aim to provide (...) a useful introduction to the book’s contents and critique some of its main claims. (shrink)

James Beilby’s Epistemology as Theology is the first monograph to address Alvin Plantinga’s completed Warrant Trilogy. The book provides a thorough introduction to Plantinga’s current religious epistemology, but readers hoping for a critical treatment of Plantinga will be largely disappointed: while Beilby does level criticisms against Plantinga, he often underestimates their significance. One of Beilby’s main goals is to sketch out how a version of Reformed epistemology, even if not exactly Plantinga’s version, can withstand its critics. I provide a chapter-by-chapter (...) examination of Beilby’s book, and argue his defense of Reformed epistemology is not obviously a significant improvement over Plantinga’s. (shrink)
