Ah so we finally agree on something.
What about the "proof" that detecting inconsistent
axioms is impossible? (I thought that I remebered this).

 A method that can always determine whether a set of axioms is inconsistent
does not exist. However, there are methods that can correctly determine
about some axiom systems that they are inconsistent and fail on others.
 The proof is just another proof that some function is not Turing computable.
 

A finite set of axioms would seem to always be verifiable
as consistent or inconsistent.  This may be the same for
a finite list of axiom schemas.
