Single Idea 7725

[catalogued under 19. Language / E. Analyticity / 1. Analytic Propositions]

Full Idea

'It is raining or it is not raining' appears to true because of the general principle 'p or not-p', so it is analytic; but this does not fit Kant's idea of an analytic truth, because it is not obvious that it has a subject concept or a predicate concept.

Gist of Idea

'P or not-p' seems to be analytic, but does not fit Kant's account, lacking clear subject or predicate

A Reaction

The general progress of logic seems to be a widening out to embrace problem sentences. However, see Idea 7315 for the next problem that arises with analyticity. All this culminates in Quine's attack (e.g. Idea 1624).

Idea 1624 If we try to define analyticity by synonymy, that leads back to analyticity [Quine]
