   If G is true and not provable then you have   
   the wrong kind of true. I have known that   
   the entire body of knowledge is a semantic   
   tautology for 28 years.   
      
   Now I have all of the details to prove how   
   any sort of "true and unprovable" has always   
   been complete nonsense:   
      
   Proof theoretic semantics anchored in the values   
   of true / false / non-well-founded derived from   
   axioms where non-well-founded are expressions that   
   are not truth-apt.

              My 28 year goal has been to make
       "true on the basis of meaning expressed in language"
       reliably computable for the entire body of knowledge.

              This required establishing a new foundation
