This paper presents a critical analysis of Alvin Plantinga’s recent contention, developed in Warranted Christian Belief (forthcoming), that if theism is true, then it is unlikely that religious unbelief is the product of properly functioning, truth-aimed cognitive faculties. More specifically, Plantinga argues that, given his own model of properly basic theistic belief, religious unbelief would always depend on cognitive malfunction somewhere in a person’s noetic establishment. I argue that this claim is highly questionable and has adverse consequences for Plantinga’s epistemology of religious belief. Plantinga’s proper basicality thesis together with his view of rationality defeaters suggests that there are circumstances in which theistic belief would not be proper function rational even if theism is true.

Philip Quinn’s “On Finding the Foundations of Theism” is both challenging and important. Quinn proposes at least the following four theses: (a) my argument against the criteria of proper basicality proposed by classical foundationalism is unsuccessful, (b) the quasi-inductive method I suggest for arriving at criteria of proper basicality is defective, (c) even if belief in God is properly basic, it could without loss of justification be accepted on the basis of other propositions, and (d) belief in God is probably not nowadays properly basic for intellectually sophisticated adults, There is much to be said about each of these four theses; I shall say just a bit about them. I take the fourth claim to be the most important and devote the most space to it.

Foundationalist epistemologies, whether internalist or externalist, ground noetic structures in beliefs that are said to be foundational, or properly basic. It is essential to such epistemologies that they provide clear criteria for proper basicality. This proves, I argue, to be a thorny task, at least insofar as the goal is to provide a psychologically realistic reconstruction of our actual doxastic practices. I examine some of the difficulties, and suggest some implications, in particular for the externalist epistemology of Alvin Plantinga.

Alvin Plantinga’s account of proper basicality, which suggests a “broad foundationalism,” raises nagging questions. A first such question is how a disposition to accept certain beliefs as properly basic could contribute to their being so. A second is whether broadfoundationalists can really make headway in identifying the criteria of proper basicality by using, as Plantinga suggests, an inductive approach. A third is whether members of the set of statements that give criteria for proper basicality are (a) themselves properly basic and (b) necessary or only contingent truths. I argue that each of these questions has a satisfactory answer, although at Ieast one inductive approach to detennining proper basicality fails.
