Single Idea 14531

[catalogued under 10. Modality / C. Sources of Modality / 1. Sources of Necessity]

Full Idea

Instead of regarding counterfactuals as conditionals restricted to a range of possible worlds, we can define the necessity operator by means of counterfactuals. Metaphysical necessity is a special case of ordinary counterfactual thinking.

Gist of Idea

Rather than define counterfactuals using necessity, maybe necessity is a special case of counterfactuals

A Reaction

[compressed] I very much like Williamson's approach, of basing these things on the ordinary way that ordinary people think. To me it is a welcome inclusion of psychology into metaphysics, which has been out in the cold since Frege.
