From Plato to the present, intuition plays a central role in epistemology. My concern in this paper is with the nature and epistemic status of intuition. To that end, I will be reviewing both Bealer's and Wittgenstein's accounts of intuition. I will be arguing that by 'intuition' Bealer understands modal intuition that has Platonic and metaphysical roles. Subsequently, I shall also show that although Wittgenstein's view avoids these two issues, it amounts to the idea that intuition is a normative activity with a dialectical value. As a result, if Bealer and Wittgenstein are right, then intuition should no more have any epistemic and evidential role.

This article lays the groundwork for a defense of rational intuitions by first arguing against a prevalent view according to which intuition is a distinctive psychological state, an "intellectual seeming" that p, that then constitutes evidence that p. An alternative account is then offered, according to which an intuition that p constitutes non-inferential a priori knowledge that p in virtue of the concepts exercised in judging that p. This account of rational intuition as the exercise of conceptual capacities in a priori judgment is then distinguished from the dogmatic, entitlement and reliabilist accounts of intuition's justificatory force. The article concludes by considering three implications of the proposed view for the Experimental Philosophy movement.

Many philosophers accept a view—what I will call the intuition picture—according to which intuitions are crucial evidence in philosophy. Recently, Williamson (2004, 2007 Ch, 1) has argued that such views are best abandoned because they lead to a psychologistic conception of philosophical evidence that encourages scepticism about the armchair judgments relied upon in philosophy. In this paper I respond to this criticism by showing how the intuition picture can be formulated in such a way that it is: (I) consistent with a wide range of views about not only philosophical evidence but also the nature of evidence in general, including Williamson's famous view that E=K; (II) can maintain the central claims about the nature and role of intuitions in philosophy made by proponents of the intuition picture; (III) does not collapse into Williamson’s own deflationary view of the nature and role of intuitions in philosophy; and (IV) does not lead to scepticism.
