 Among those who think that justification is internal, there is no unanimity on how to understand the notion of internality—i.e., what it is about the factors that you share with your BIV doppelganger that makes those factors relevant to justification. We can distinguish between two approaches. According to the first, justification is internal because we enjoy a special kind of access to J-factors: they are always recognizable on  reflection.[31]  Hence, assuming certain further premises (which will be mentioned momentarily), justification itself is always recognizable on  reflection.[32]  According to the second approach, justification is internal because J-factors are always mental states (see Conee and Feldman 2001). Let’s call the former accessibility internalism and the latter mentalist internalism.
