Single Idea 11166

[catalogued under 10. Modality / C. Sources of Modality / 1. Sources of Necessity]

Full Idea

We naturally suppose, if a subject-predicate proposition is necessary, that the subject of the proposition is the source of the necessity. But that singleton 2 contains 2 is necessary, whether the number or the set is the subject of the proposition.

Gist of Idea

The subject of a proposition need not be the source of its necessity
