[catalogued under 10. Modality / E. Possible worlds / 1. Possible Worlds / a. Possible worlds]

Full Idea

The main benefit of the possible worlds move is to permit one to paraphrase modal claims in an extensional language that has quantifiers, but no modal auxiliaries, so the semantic stucture of modal discourse can be discussed without the controversies.

Gist of Idea

Possible worlds allow discussion of modality without controversial modal auxiliaries

A Reaction

The strategy introduces the controversy of possible worlds instead, but since they just boil down to collections of objects with properties, classical logic can reign. Possible worlds are one strategy alongside many others.
