 Second, if a priori justification is possible, exactly what does it involve? What makes a belief such as “All bachelors are unmarried” justified? Is it an unmediated grasp of the truth of this proposition? Or does it consist of grasping that the proposition is necessarily true? Or is it the purely intellectual state of “seeing” (with the “eye of reason”) or “intuiting” that this proposition is true (or necessarily true)? (see Bengson 2015 and Chudnoff 2013 for sophisticated defenses of this view). Or is it, as externalists would suggest, the reliability of the cognitive process by which we come to recognize the truth of such a proposition?
