AllI guess you haven't read the papers of Zermelo and Fraenkel. They created a new definition of what a set was, and then showed what that implies, since by changing the definitions, all the old work of set theory has to be thrown out, and then we see what can be established.ZFC didn't need to do that. All they had to do isIf you want to do that, you need to start at the basics are totally reformulate logic.Not at all. I am doing the same sort thing that ZFC*This abolishes the notion of undecidability*But you clearly don't understand the meaning of "undecidability"
As with all math and logic we have expressions of language
that are true on the basis of their meaning expressed
in this same language. Unless expression x has a connection
(through a sequence of true preserving operations) in system
F to its semantic meanings expressed in language L of F
x is simply untrue in F.
did to conquer Russell's Paradox.
redefine the notion of a set so that it was no longer
incoherent.
of these are the effects of the change of the
definition of a set.
Axiom of extensibility: the definition of sets being equal, that ZFC is built on first-order logic.Axion of regularity/Foundation: This is the rule that a set can not be a member of itself, and that we can count the members of a set.This one is the key that conquered Russell's Paradox.
If anything else changed it changed on the basis of this change
or was not required to defeat RP.
I think you problem is you just don't understand how formal logic works.
You can't do fundamental logic in the abstract.
That is just called fluff and bluster.
All that they did is just like I said they redefinedShowing the sort of thing YOU need to do to redefine logic
what a set is. You provided a whole bunch of details of
how they redefined a set as a rebuttal to my statement
saying that all they did is redefine a set.
You show the steps of how ZFC redefined a set as your rebuttal.
They developed a full formal system.
a set and the result of this was a new formal system.
One change had many effects yet was still one change.
When any tiniest portion of the meaning of an expression
has been defined this teeny tiny piece of the definition
makes this expression not pure random gibberish.
Meaningless does not mean has less meaning, it is
an idiom for having zero meaning.
