Single Idea 19287

[catalogued under 10. Modality / A. Necessity / 6. Logical Necessity]

Full Idea

We can distinguish between narrower and broader kinds of logical necessity. There are, for example, the logical necessities of propostional logic, those of first-order logic, and so on. Maybe they are necessities expressed using logical vocabulary.

Gist of Idea

Maybe each type of logic has its own necessity, gradually becoming broader

A Reaction

Hale goes on to prefer a view that embraces conceptual necessities. I think in philosophy we should designate the necessities according to their sources. This might clarify a currently rather confused situation. First-order includes propositional logic.
