Some sentences are true, some are false, and some are neither. According to what seem to be the usual standards, questions are neither true nor false; neither are optatives; neither are imperatives. A sentence with a truth value is a sentence in the indicative mood. But not all sentences in the indicative mood have truth values. Occasion sentences have no truth values they can call their own; only their utterances have truth values. Nor is it clear even that all utterances of indicative sentences have truth values; for there is the matter of truth-value gaps. If a sentence contains a singular term that fails to designate, then the utterances of the sentence may lack truth value; Strawson has plausibly urged that this account usually fits ordinary usage.
