   The problem I have wih Pete Olcott's posts over the past 20 years at least is   
   that he doesn't have a clue what a human language is.   
      
   I don't mind if he wants to bore readers of comp.theory, sci.logic, sci.math,   
   and comp.ai.philosophy with his stuff (though others may), but can he not drop   
   sci.lang from the list?   
      
   In any case it's rarely acceptable to send the sama message to more than three   
   groups (even as many as that).
