Single Idea 19299

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

Full Idea

The standard conception of worlds incorporates the assumption of bivalence - every proposition is either true or false. But it is infelicitous to build into one's basic semantic machinery a principle endorsing classical logic against its rivals.

Gist of Idea

Possible worlds make every proposition true or false, which endorses classical logic

A Reaction

No wonder Dummett (with his intuitionist logic) immediately spurned possible worlds. This objection must be central to many recent thinkers who have begun to doubt possible worlds. I heard Kit Fine say 'always kick possible worlds where you can'.
