My purpose in this paper is to examine the role of intuition in conceptual analysis and to assess whether that role can be parlayed into a plausible defense of a priori knowledge. The focus of my investigation is George Bealer’s attempt to provide such a defense. I argue that Bealer’s account of intuition and its evidential status faces three problems. I go on to examine the two primary arguments that Bealer offers against empiricism: the Starting Points Argument and the Argument from Epistemic Norms. I argue that the Starting Points Argument fails because Bealer fails to show that intuitions are a priori evidence and that the Argument from Epistemic Norms fails because it is open to the Stalemate Problem. I conclude by offering an alternative approach to defending the a priori status of intuitions that avoids the Stalemate Problem. The alternative approach highlights the role of empirical investigation in defending the a priori.

David Henderson and Terry Horgan offer a detailed account of the structure of conceptual analysis that is embedded within a more general account of a priori justification. Their account highlights an important feature of conceptual analysis that has been overlooked in the recent debate. Although it is generally recognized that conceptual analysis involves an inference from premises to the effect that some concept does (or does not) apply to a range of particular cases to a general conclusion about the nature of the concept itself, the details of that inference have not been fully articulated. Henderson and Horgan offer an articulation of the inferential connection which, taken in conjunction with their account of a priori justification, yields a startling conclusion about the epistemic status of the results of conceptual analysis. My view is that their account of a priori justification misses the mark and, as a consequence, they arrive at a conclusion about the epistemic status of the results of conceptual analysis that many will find implausible. Moreover, I fear that because many will find their overall conclusion implausible, they will either overlook or dismiss the important feature of the inferential connection that Henderson and Horgan correctly highlight. Hence, I have two goals. First, I want to track down the source of their mischaracterization of the a priori and to show why it is a mischaracterization. Second, I want to highlight the important feature of the inferential connection involved in conceptual analysis that they identify, articulate its bearing on the debate over the existence of a priori knowledge and assess its implications.

Edward Erwin has recently argued against the thesis that the concepts a priori truth’ and ‘necessary truth’ are extensionally equivalent. This thesis consists of two logically independent claims: all a priori truths are necessary; and all necessary truths are a priori. Erwin leaves the first claim unchallenged and elects to devote his efforts exclusively to undermining the second. The brunt of his attack on the second claim rests on alleged unclarities in the concept of an a priori truth. He attempts to show that the E.E.H. cannot be defended upon any plausible interpretation of this concept. Although I agree that the E.E.H., as stated above, is open to Erwin's objections, I shall argue that a slightly revised version of it can be defended against these objections.

Kripke claims that there are necessary a posteriori truths and contingent a priori truths. These claims challenge the traditional Kantian view that (K) All knowledge of necessary truths is a priori and all a priori knowledge is of necessary truths. Kripke’s claims continue to be resisted, which indicates that the Kantian view remains attractive. My goal is to identify the most plausible principles linking the epistemic and the modal. My strategy for identifying the principles is to investigate two related questions. Are there compelling general supporting arguments for (K)? Are there decisive counterexamples to (K)? My investigation uncovers two intuitively plausible principles that are not open to decisive counterexamples but which enjoy no compelling independent support.
