Robert Oakes has argued that theism defeats the ‘doctrine of public-world fallibilism’. That is, Oakes has argued that theism supports infallibilism about public-world beliefs such as ‘There is an olive on the floor’, or ‘I have two hands’. Given the enormous discussion of radical scepticism in the recent epistemological literature, this argument is well worth investigating. In this short note, however, I argue that the argument Oakes presents is unconvincing. The truth of theism does not support public-world infallibilism.
