Full Idea
The notion of fitting the totality of experience ...adds nothing intelligible to the simple concept of being true. ....Nothing, ...no thing, makes sentences and theories true: not experience, not surface irritations, not the world.
Gist of Idea
Saying truths fit experience adds nothing to truth; nothing makes sentences true
