 Austin makes no claims to generality for the account of truth that he sketches. However, it’s natural to wonder to what extent the account can naturally be extended in order to take in types of statement that he doesn’t explicitly attempt to bring within its purview. Potential pressure points here include statements whose expression involves negation (see 1950a: 128–129, 129 fn.1), quantification (see 1962b: 144), or conditionals, and statements of necessary truths. The three main options open to the defender of Austin here are the following. First, an attempt might be made to bring some cases within the purview of a natural generalization of Austin’s account (see, for example, Warnock 1989: 56–61). Second, it might be allowed that some such cases require distinctive treatment, but argued that they can still be connected with the account Austin offers as further species of the truth-genus. Third, an attempt might be made to argue that some such cases are so distinctive that the forms of positive appraisal that are appropriate to them are not really forms of appraisal as to  truth.[16]
