    Well-founded proof theoretic semantics where
    True(L, x) is anchored in provability from
    the axioms of formal system L seems to
    eliminate the undecidability that model
    theoretic semantics encounters when truth is
    measured from outside of the formal system in
    a separate model.

    But GOdel's proof wasn't based on a truth outside the system.

    The proof was based outside the system, but only about things actually
    in the system.

    Your problem is you don't seem to understand the rule of context, and
    ignore what is actually being said.

    There *IS* no number g that satisfies that relationship that he build IN
    PA. There is also no proof in PA of this fact.

    THere is also no proof in PA that you can't prove the fact.

    THus, your "proof theoretic semanrtics" just don't know what to do about
    the statement, it is outside their ability to process, and thus make the system just incomplete in its own reasoning. They can't even say it is
    outside its ability, as it just can't show that either.


    This is the *FORMAL* epistemology of:
    "true on the basis of meaning expressed in language"


    Which just can't handle mathematics, as you STILL can't explain how you
    get from the meaning of the words:

    The sum of the squares of the length of the two sides of a right triange
    is equal to the square of the length of the hypotenuse.


    So, I guess you aren't talking about the problems people actually want
    to handle.

    Nope, when in the system, that is all you know.

    I guess you are just admitting that proof-theoretic semantics aren't
    viable to use, as you think you need to allow looking at proofs outside
    the system.

    and, since there is an infinite number of possible meta-systems
    derivable from a given system, to talk about the non-existence of such a
    proof is an unanswerable question, it means the only reliable way to
    show there isn't a proof of a statement, is to show the proof of its
    negation, or that the statement itself is a contradiction.

    Nope.

    The existance of non-existance of a number is the same inside and outside.

    You may want to try to define this as meaning the statement is not true,
    but that only says that statements about "Mathematics" are outside the
    system, even though they are derivable in the system.

    Your problem is you just don't understand what is actualy meant by
    Truth, and think it is just freely redefinable.

    It is just a FACT that it has been shown that "Proof-Theoretic
    Semantics" become unstable and not useful in systems powerful enough to
    handle the Natural Numbers, like Peano Arithmetic.

    Trying to deny that is just admitting you don't mind your world being
    built on lies.

    No, but the outside can know everything about the inside, and make
    things that work on the inside.

    Note, in particular, the "Mathematics" of Peano Arithmatic hold in both
    the bases system and the meta-math, so any property of mathematics in
    the mase system is also a property in the meta-math.

    Thus, the Primitive Recursive Relationship derived in the meta-math will
    have exactly the same numbers satisfy it in the base system as in the meta-math.

    The only really difference is that in the base system, it is just math
    on numbers, but in the meta-math, the numbers are encodings of
    statements, and the math is equivalent to logical operations that he
    shows to actually be equivalent.

    WHich has the Natural Numbers, and thus the relationship, which is

    Nope, didn't say that.

    Note, The "Natural Numbers" are just one "model" of mathematics. One way
    to define them is Peano Arithmatic. So being in PA is defining the model

    You also get models of mathematics like the Reals, which don't come from
    just PA (normally PA + some more axioms to extend the model).

    It seems you don't understand that defining we are in Peano Arithmatic
    (PA) defines the base model we are using (it might be a higher level
    model too).

    It seems you don't really understand the words you are using.
