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
