   That relationship has never existed inside actual   
   arithmetic; it exists only in meta‑mathematics, which   
   people often misconstrue as arithmetic itself.   
   Satisfaction is not a notion available within   
   arithmetic—only within models of arithmetic.

              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
