In other words, to determine the value of now we have to know when the sentence is uttered and it differs from time to time. Let ϕ and ψ be two propositions: ϕ presupposes ψ if and only if ψ is a precondition of the truth or falsity of ϕ. I.e., if ϕ is true or false, then ψ is true.

We will refer to these relations as t-entailment, f-entailment, q-en- tailment and p-entailment, correspondingly. Whereas t-entailment is the standard truth-preserving relation, f-entailment incorporates the idea of non-falsity preservation (cf. , p. 10).
