   Your construction is impossible, as proven by Gödel's Incompleteness   
   Theorem.   
      
   You didn't "show" anything.  You just waved your hands and expect   
   everybody to accept your continually repeated falsehoods.

   I suggest you look up isomorphism in Wikipedia to find out what it   
   actually means.

   It has nothing to do with my understanding, and a great deal to do with   
   your lack of it.  You have not proven that a counter example to whatever   
   it is you're talking about is "categorically impossible".  You can't,   
   since you lack the prerequisites to understand what constitutes a proof,   
   and you lack the mathematical foundations to be able to construct one.

   Arithmetic, for a start.  If that allegedly "entire body of knowledge"   
   was capable of doing arithmetic, Gödel's Incompleteness Theorem would   
   apply to it.  That is a proof by contradiction that such a body of   
   knowledge cannot exist.
