 For Ryle to remind us that we do, as a matter of fact, have a way of settling disputes about whether someone is vain or whether she is in pain is much weaker than saying that a concept is meaningless unless it is verifiable; or even that the successful application of mental predicates requires that we have a way of settling disputes in all cases. Showing that a concept is one for which, in a large number of cases, we have agreement-reaching procedures (even if these do not always guarantee success) captures an important point, however: it counts against any theory, say, of vanity or pain that would render it unknowable in principle or in practice whether or not the concept is correctly applied in every case. And this was precisely the problem with the Official Doctrine (and is still a problem, as I suggested earlier, with some of its contemporary progeny).
