Sentence examples for false sentence from inspiring English sources

Every true (false) sentence has the same referent: the True (the False).

For this reason in the commentary on the Categories Paul distinguishes between the significate of a true sentence and the significate of a false sentence.

Although (i) and (ii) are intensionally equivalent, substituting (i) for (ii) and (ii) for (i) in (iii) yields the false sentence 'Socrates exists because {Socrates} exists'.

Moreover, he now identifies the significate of any false sentence with a second mental proposition existing obiective and not subiective in our intellect.

Hence, in accordance with the classical substitutivity principle for sentences, we can replace the occurrence of (1) with (2) in the false sentence and the result is the equally false sentence However, when we make the same substitution in the true sentence the result is the sentence which is intuitively false, as John surely could have had a non-mammalian pet.

By contrast, (2) is not a logical truth: one could easily hold fixed its logical structure, but vary the meaning of 'bachelor' or 'unmarried' and thereby produce a grammatical but false sentence.

Some stay within Popper's essentially syntactic paradigm, comparing classes of true and false sentences (e.g. Newton Smith 1981).

As Church remarks, a parallel example involving false sentences can be constructed in the same way (by considering, e.g., 'Sir Walter Scott is not the author of Waverley').

This happens for instance when a logician constructs a valid syllogism made up of materially false sentences to give examples of formally valid inferences (§44, 130).

Others deny that their contents are true or false in any robust sense but not that they can be true or false in a deflationary sense according to which there is no substantial property separating true and false sentences.

Facts, on the other hand, cannot be identified with the meanings or contents of sentences or mental states, on pain of the absurd consequence that false sentences and beliefs have no meaning or content.
