   Gödel 1931 undecidability and Tarski Undefinability   
   only exist because they they not know to reject an   
   expression of language that is not a truth bearer.   
      
   Claude AI is quite hesitant at first, disagreeing   
   with me several times. Then it is finally convinced   
   that I am correct.

   My scope is the entire body of human knowledge   
   that can be expressed in language.
