 Bealer seems to disagree with Casullo about the nature of intuitions. He has written that empirical investigation into people’s “intuitions” is irrelevant because they do not investigate intuitions in the relevant sense, that is, intuitions understood as responses to fully understanding propositions (1998: 202). Casullo seems to understand intuitions differently, as a certain kind of mental state whose nature must be discovered empirically. Insofar as a defense of rationalism involves a defense of the epistemic role of intuitions, it is not surprising that Bealer and Casullo suggest different ways of defending rationalism given that they have different views about the nature of intuitions.
