Single Idea 18496

[filed under theme 10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds ]

Full Idea

If the other possible worlds are merely useful fictions, we are left wondering what the truthmakers for all those modal judgements might be.

Gist of Idea

If possible worlds are just fictions, they can't be truthmakers for modal judgements

A Reaction

I suddenly see that this is the train of thought that led me to believe in real powers and dispositions, and which retrospectively led me to love the truthmaker idea. Even real Lewisian worlds don't seem adequate as truthmakers here.
