   What do you think is missing from   
   "true on the basis of meaning expressed in language"   
   about natural numbers?   
   add/subtract/multiply/divide is all there

              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
