Single Idea 19294

[filed under theme 10. Modality / C. Sources of Modality / 6. Necessity from Essence ]

Full Idea

If the essentialist theory of necessity is to be adequate, it must be able to explain how the existence of certain objects - such as the natural numbers - can itself be absolutely necessary.

Gist of Idea

If necessity derives from essences, how do we explain the necessary existence of essences?

A Reaction

Hale and his neo-logicist pals think that numbers are 'objects', and they necessarily exist, so he obviously has a problem. I don't see any alternative for essentialists to treating the existing (and possible) natures as brute facts.
