 Epistemological disjunctivism fits naturally with metaphysical disjunctivism, although neither implies the other. The proponent of both can claim that the reason we are justified in the good case but not in the bad is that a veridical perceptual experience is a distinct type of mental state from a hallucination and that different types of mental states frequently have different evidential significance. An epistemological disjunctivist who denied metaphysical disjunctivism would claim that we are in the same mental state in both cases but that the justificatory potency of an experiential state is partly determined by further factors, including the veridicality or not of the experience. On the standard mentalist understanding of internalism, the latter view is clearly externalist; the former view might count as internalist, at least on a rather unusually liberal understanding of internalism, which allows the supervenience base for justification to include factive mental states.
