(16) This is not true.(17) This either fails to express a proposition or is not true.
He introduces a distinction between ordinary negation ‘¬’ and a notion of ‘false or does not express a proposition’, symbolised ‘—‘ . He writes: ‘By writing down ─A, one simply performs the speech act of rejecting A as untrue—an act one may well wish to perform when A itself fails to say anything.’ (p. 22); ‘I do not suppose that ─A expresses any propositional content when A does not’; and ‘a negatively signed formula ─A is correct if and only if A is untrue’ (pp. 21-2).
(18) This speech-act is not correct.
