So, you thing truth is just paradoxical or ungrounded? I guess that throws a wrench in your idea of a universal system to determine what is true. If true might not be true, what can we say about anything. > > *Outline of a Theory of Truth --- Saul Kripke* > https://www.impan.pl/~kz/truthseminar/Kripke_Outline.pdf > > *The grounding of a truth-bearer to its truthmaker* > True(L,x) returns true when x is derived from a set of truth preserving > operations from finite string expressions of language that have been > stipulated to have the semantic value of Boolean true.
