A proposition is incorrigible if it cannot be corrected; that is, it is not possible that belief in it should be found to be mistaken. Although many candidates have been proposed, ranging from first-person introspective reports to basic logical axioms, it is widely held that a proposition could achieve the status only by saying nothing. Any proposition with real content would involve bringing a particular situation under some rule of description, and the possibility of mistaken application always arises. In that case the search for incorrigible starting-points in the theory of knowledge is misguided. See also epistemology, foundationalism.
