   There is a correct mapping of finite strings   
   to the semantic meaning that they specify.   
      
   individual means one.   
   a group of individuals is not one individual

   My 28 year goal has been to make   
   "true on the basis of meaning" computable.   
      
   This required establishing a new foundation   
   for correct reasoning.
