Single Idea 16132

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

Full Idea

To tell the alleged truth about contradictory things that happen on a mountain is just contradicting yourself, but you can't tell the truth by contradicting yourself. There is no mountain where contradictions are true, and impossible worlds are no better.

Gist of Idea

On mountains or in worlds, reporting contradictions is contradictory, so no such truths can be reported


David Lewis (On the Plurality of Worlds [1986], 1.2 n3)

A Reaction
