Single Idea 8206

[catalogued under 10. Modality / A. Necessity / 11. Denial of Necessity]

Full Idea

The need to add a note of necessity to 'all black crows are black' could be met by a generalisation over classes (what belongs to sets x and y belongs to y), or maybe be quantifying over possible particulars.

Gist of Idea

Necessity could be just generalisation over classes, or (maybe) quantifying over possibilia

A Reaction

He dislikes the second strategy because 'unactualized particulars are an obscure and troublesome lot'. The second is the strategy of Lewis. I think necessity starts to creep back in as soon as you ask WHY a generalisation holds true.
