 Incorrigibility does not imply infallibility: I may not actually be in pain, even if no one could show that I’m not. Consequently, incorrigibility is compatible with a broader array of sources of self-knowledge than is infallibility. Neither Rorty nor Dennett, for example, appear to defend incorrigibility by appeal to self-fulfillment accounts of introspection (though in both cases, interpreting their positive accounts is difficult). Causal accounts of self-knowledge may be compatible with incorrigibility if the causal connections underwriting the incorrigible judgments are vastly more trustworthy than judgments obtained without the benefit of this sort of privileged access. Of course, unless one embraces a strict self-fulfillment account, with its attendant infallibilism, one will want to rule out abnormal cases such as quantum accident; hence the need for qualifications.
