I decided |truth| looked like a mathy way to signify “absolute truth”, based on how we say “|v|” for “absolute” value of v.
My investigation is into a context for |truth| (cite Jon), beginning with: what is the language this |truth| is couched in?
To what extent are maths “a partially overlapping set of languages”?
