   Given that your ideas strongly tend to violate firmly established   
   mathematical results, there is no such impossibility as you assert.  Note   
   that if you hold established results to be false, you have the burden of   
   proof.  At no time in this newsgroup have you met this obligation.   
      
   > A mere dogmatic assertion provides zero actual evidence

   I don't need to provide evidence.  As just written, the burden of proof   
   is on your side.   
      
   > A consistent finite set of basic facts of the world is possible.   
      
   There are many such finite sets, but none of them are complete, and they   
   cannot be complete.  This was demonstrated by mathematicians in the early   
   20th century.

   This is a will o' the wisp, as much as Frege's or Russell and Whitehead's   
   much more modest attempts to formalise all of mathematics were.

   As I keep saying, the burden of proof is on your side.  The three   
   mathematicians just mentioned failed because what they were attempting   
   was fundamentally impossible.  That was not yet understood in the early   
   years of the twentieth century, but it is firm knowledge now.  What you   
   are insisting can be done is a superset of these impossibilities.   
      
   There is a lot of hubris involved here, and seemingly not a little   
   personal insecurity, in someone who cannot accept reality as it is.

   The "details" you "specified" were just hand-waving nonsense, not based   
   on any firm logical or mathematical results.  Therefore they can be   
   justifiably disregarded.

   Neither do I.  Not relevant, since I don't have any such learned by rote   
   definitions of a proof.   
      
   > The most generic form of a proof is essentially a semantic tautology.   
      
   That's neither here not there, being too abstract to be of use.

   I'm saying that any system of knowledge in which Gödel's Incompleteness   
   Theorem doesn't apply is either inconsistent or incapable of doing   
   arithmetic.
