Abstract

John Bengson holds that an intellectual seeming is sufficient for a priori justification, whereas Elijah Chudnoff disagrees and holds that a priori justification also requires an intuitive awareness of the abstract entities that are the subject matter of the proposition to be justified. I distinguish between substantive and non-substantive a priori claims about the world, and argue that Chudnoff is correct about the justification required for the former kind of claim, and Bengson is correct about the justification required for the latter. In brief, substantive a priori claims about the world require for justification a process of reflection that takes as input states of awareness of the abstract entities in the world that are the subject matter of the claim, and yields as output an intellectual seeming that the claim is true. Whereas non-substantive a priori claims about the world (merely conceptual claims) can be justified merely by an intellectual seeming that the claim is true, so long as the seeming is a manifestation of conceptual competence.
