 It may be argued, however, that, if the Reformed epistemologist’s model is correct, those who seek to meet an evidentialist requirement will be unable to satisfy themselves of their entitlement to their faith. Theistic truths may be directly revealed, and experienced as immediately evident, yet, on reflection, one may doubt whether such experiences are genuinely revelatory since competing ‘naturalist’ interpretations of those experiences seem available. Furthermore, there are rival sources yielding contrary claims that equally claim to be authentically revelatory. It may be true, as Plantinga’s Reformed epistemology maintains, that if God exists then certain basic theist beliefs meet externalist criteria for knowledge, even though the truth of the propositions concerned remains open to reflective ‘internalist’ doubt. On an externalist account, that is, one might lack independent evidence sufficient to confirm that one has knowledge that God exists while in fact possessing that very knowledge. One may thus refute an objector who claims that without adequate evidence one cannot possess knowledge. But this consideration is still insufficient to secure entitlement to theistic faith—if, as may be argued, that entitlement requires that one has evidence adequate to justify commitment to the truth that God exists. For, one has such evidence only conditionally on God’s existence—but it is precisely entitlement to believe that God exists that is at issue (Kenny 1992, 71; Bishop and Aijaz 2004). For a wider discussion of the possibility of religious knowledge that, inter alia, endorses the present point, see Zagzebski 2010.
