  The evidence is particularly strong if we focus on complete justifier versions of accessibility internalism. On that view it is held that all of the justifiers for any given belief are accessible by reflection. If it is true in fact that everything that is accessible by reflection is a mental state, then mentalism will follow directly from this fact coupled with complete justifier internalism. With a partial justifier account of accessibility internalism, which we noted earlier is the more plausible internalist position, matters are different. On that view it is required that the cognizer merely be able to access by reflection some of the justifiers for any given belief. Hence, this position will permit cases in which the justifiers that are accessible by reflection are all mental states, but other inaccessible justifiers are not. Mentalism, though, is a view about the character of all of the justifiers, to the effect that all justifiers are mental states. So, while we can agree that a partial justifier account of accessibility internalism is evidence for mentalism, the evidence is not as strong as one might initially expect.
