Alvin Plantinga thinks Leibniz made a mistake. Leibniz claimed that God could have created any possible world, but Plantinga thinks this view amounts to a lapse in judgment on Leibniz =s part. = Plantinga terms this mistake ALeibniz= Lapse,@ and his rejection of this Leibuizian claim plays an important role in Plantinga =s free wili defense against the problem of evil. I will argue that Plantinga fails to show that Leibniz lapsed in thinking about which worlds are actualizable by God; in particular, his argument for this claim is not sound. If I am right, the last lapse is on Plantinga.

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.
