Professor Leonard proposes that imperative and interrogative sentences be classified, together with declarative ones, as true and false. The interesting analysis he gives in connection with this proposal points out that these three types of utterance have something in common and has the merit of evincing the identity of this common element. Also it may seem to offer attractive possibilities of integrating various types of discourse in its promise of partial assimilation of interrogatives and imperatives to the model of truth-valuable (...) language. Even so, Leonard's account is not altogether satisfactory. I shall not discuss his treatment of imperatives but shall argue that his conception of interrogatives has unacceptable consequences.
