Warrant, defeaters, and the epistemic basis of religious belief

I critically examine two features of Plantinga’s Reformed Epistemology. (i) If basic theistic beliefs are threatened by defeaters (of various kinds) and thus must be defended by higher-order defeaters in order to remain rational and warranted, are they still “properly basic”? (ii) Does Plantinga’s overall account offer an argument that basic theistic beliefs actually are warranted? I answer both questions in the negative.
