Single Idea 16543

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

Full Idea

If we can truly affirm that it is part of the essence of some entity that p is the case, then p is an essential truth and so a metaphysically necessary truth.

Gist of Idea

If an essence implies p, then p is an essential truth, and hence metaphysically necessary

-: 'Mind' [-], p.20

A Reaction

This feels too quick. He is trying to expound the idea (which I like) that necessity derives from essences, and not vice versa. Is it a metaphysical necessity that there are no moths in my wardrobe, because mothballs have driven them away? Maybe.
