A Priori Knowledge
This paper has three parts. First, a discussion of our use of intuitions as evidence (reasons) in logic, mathematics, philosophy (hereafter, “the a priori disciplines”). Second, an explanation of why intuitions are evidence. The explanation is provided by modal reliabilism—the doctrine that there is a certain kind of qualified modal tie between intuitions and the truth. Third, an explanation of why there should be such a tie between intuitions and the truth. This tie is a consequence of what, by definition, it is to possess the concepts involved in our intuitions. These three parts form the basis of a unified account of a priori evidence and, in turn, a priori knowledge.
