Single Idea 3882

[catalogued under 19. Language / F. Communication / 4. Private Language]

Full Idea

Wittgenstein's point is that if I search for foundations in what can only be known to me, then the belief that I have discovered those foundations will also fall victim to Descartes' demon.

Clarification

He said a private language, with one speaker, was a logical impossibility

Gist of Idea

Wittgenstein makes it impossible to build foundations from something that is totally private

A Reaction

Why should foundations based in wider society or a language community fare any better? Getting a lot of people to agree won't trouble the demon too much. Flat earthers.
