   F ⊢ G_F ↔ ¬Prov_F(⌜G_F⌝)   
   F proves that: G_F is equivalent to G_F is not provable in F

   ∃G ∈ WFF(F) (G ↔ (F ⊬ G))   
   There exists a G in F that is logically   
   equivalent to its own unprovability in F   
      
   ∃G ∈ WFF(F) (G := (F ⊬ G))   
   There exists a G in F that asserts its own unprovability in F   
      
   The proof of G in F would seem to require a sequence   
   of inference steps in F that prove that they themselves   
   do not exist.

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

              This required establishing a new foundation
