Full Idea
1,000 years ago, no sentence had ever expressed, and no one had believed, the true proposition 'a water molecule has two hydrogen and one oxygen atoms'. There are surely true propositions that have never been, and never will be, expressed or believed.
Gist of Idea
True propositions existed prior to their being thought, and might never be thought
