The modality of theism and probabilistic natural theology: a tension in Alvin Plantinga's philosophy

Abstract

AbstractIn Wunder (2013) I observed a probabilistic blunder in Plantinga (2011) and argued that correcting it, while noting Plantinga's acceptance of logically non-contingent theism, had negative consequences for many other of his probabilistic claims. Professor Plantinga kindly replied to my correspondence, but the fruits of that conversation could not be incorporated into Wunder (2013). This article will explain the blunder and summarize my earlier arguments before addressing Plantinga's main replies. I conclude that these replies fail to circumvent most of the problems observed earlier: perhaps most significantly, the Evolutionary Argument against Naturalism and theism's logical non-contingency still appear jointly to imply theism's necessary falsehood.
