Fodor and katz criticize cavell's position on the relation between ordinary language philosophy and empirical investigations of ordinary language, In "must we mean what we say?," _inquiry, Volume 1, Pages 172-212, And "the availability of wittgenstein's later philosophy," "philosophical review", Volume 71, Pages 67-93. Cavell holds that disagreements between ordinary language philosophers over grammar and semantics are in no sense empirical. Fodor and katz show that ordinary language philosophers are engaged in empirical investigation. (staff).
