Naive set theory says that for every predicate P, the set {x | P(x)} exists. This axiom was a mistake. This axiom is not in ZFC.

The same reasoning seems to rebut Gödel Incompleteness:

When we do this exact same thing that ZFC did for self-referential

Provability in uncomputable.

Thus G cannot possibly derive a sequence of inference
steps that prove that they themselves do not exist.
It doesn't.
It shows that no proof exists of its truth.
It also shows that it can't be false, as if it were, then it would be proven to be true, and you can't prove a false statement true in a consistant system.

 
Note, the key is that G doesn't assert that, G is a statement about math, that only when interpreted in a meta-theory sees that.
>
I am not referring to that one.
Then you aren't talking about Godel, who you mentioned just before.
So, you LIE.

 
G is actually a statment about the existance of a number that matches a complected and carefully constructed relationship, that is fully computable. The Existance or non-existance of such a number is a pure binary thing, either it WILL or it WON'T.
>
The complicated relationship deals with a way to encode as a number ANY analyitic statement in F (since all statements are just strings, and strings can be encoded into a number), and a calculation to see if that statement actually is a proof starting with the enumerated truth makers of F, through the valid and allowed logical operatons to the statement of G. A number that satisfies this relation, encodes a proof of G, and any such proof, can always be encoded in to a number.
>
No formal system can possibly have any sequence of inference
step that prove that they themselves do not exist because
this is self-contradictory, not because the system is incomplete.
In my G this is obvious.
Right, You can't have, IN THE SYSTEM, a statement that something must be true and unprovable, as that is, itself, a contradiction.

 Whether or not Gödel's G is isomorphic to mine I have proved
this this is false by providing the counter-example of my G.
No, you have proved that a direct statement in F, can't assert that a statement is True but Unprovable.
But Godel G, doesn't directly assert it, but creates mathematics based on a meta-theory that establish it.
That is the power of Mathematics.

 ...14 Every epistemological antinomy can likewise be used for a similar undecidability proof...(Gödel 1931:43-44)
Which you don't understand, and is refering to logic in Meta-F, which you don't handle at all.

 
G is the statement that no such number exist. So, if G is false, then such a number exists, and then in the Meta-Theory, we can decode that number into a proof in F that G must be true.
>
If this is the case, then F must be inconsistant, and the proof starts with the presumption that we are dealing with a consistant logic system.
>
 Or it could be the epistemological antinomy of trying to find a
sequence of inference steps in F that prove that they themselves
do not exist.
It shows that F defines an epistemological statement to be true, which is equivent to F being inconsistant.
As you point out, you can't make the statement in F, you need a level of indirection with a meta-system to make it work.

 
But, if G is true, then there can be no such number, and thus from our knowledge in the mete-theory, we know that no proof CAN exist for that fact.
>
Thus, the only possiblity for this statement, is to be True, but unprovable.
>
Or it could be the epistemological antinomy of trying to find a
sequence of inference steps in F that prove that they themselves
do not exist.
You are repeating yourself, showing you self to be just the CHILDISH pathetic ignorant hypocritical pathological lying idiot.

 Meta-F can see this and F is not incomplete if it cannot accomplish
an epistemological antinomy.
 
The big part of the theory is showing that such a relationship can be made, and that shows that proof checkers are a computable function.

Given a system, and an enumeration of its basic truths, we can check if a proof present actually proves the result it claims to.
