 The ontological commitments of the Official Doctrine lead to the mind-body problem; the epistemological commitments of the Official Doctrine lead to the problem of other minds. According to the traditional view, bodily processes are external and can be witnessed by observers, but mental processes are private, “internal” as it is metaphorically described (since mental processes are not supposed to be locatable anywhere). Mental processes or events are supposed, on the official view, to be played out in a private theatre; such events are known directly by the person who has them either through the faculty of introspection or the “phosphorescence” of consciousness. The subject of the mental states is, on this view, incorrigible—her avowals of her own mental states cannot be corrected by others—and she is infallible—she cannot be wrong about which states she is  in.[6]  Others can know them only indirectly through “complex and frail inferences” from what the body does.
