  There would be a tight connection between mentalism and accessibility internalism if all of the mental states that are justifiers for beliefs were occurrent mental states. That is, if all of these states were attentively before the mind when one held a justified belief, then those states would then be accessible via introspection. Here we assume that if some mental state occurrently exists or obtains at some time, then one can turn one's attention to that state at that time. However, occurrent justifiers make up but a tiny percentage of the justifiers standing behind the large numbers of justified beliefs any person will have at any time. Any adult cognizer, for instance, is apt to have many thousands of justified beliefs at any moment, with very few if any of them occurrent at a given time, and all of them backed by justifiers. If all of these justifiers are mental states, as mentalism contends, most of them would be buried deep in one's mental storehouse, beyond the reach of reflective awareness.
