    Anything that any machine can possibly compute can

    like making a silk purse from a sow's ear.

    That "everything else" includes many thigns that would be
    useful to
    know. In particular, whether some useful function can be
    computed is
    in that "everything else".

    Like the truth value of: "This sentence is not true"
    that has no truth value.

    not for any important purpose.

    Knowing that all undecidability is merely semantic
    incoherence enables:

    "true on the basis of meaning expressed in language"
    to be reliably computable for the entire body of knowledge.

    We don't have the knowledge that all undecidability is merely semantic >>>>> incoherence, and can't know because we already know that there is
    undecidability that is not semantic incoherence. FOr example the
    axiom system

    reCx (1riax = x)

    1.5 != 5 re| you are wrong and I am couinting the rest as gibberish

    Middle dot is a commonly used mathematical operator. In this context
    where the purpose of the operation is not specified some other symbols
    are often used instead, like rey or reO, or operands are just put side by >>> side with no operator between.

    If commonly used mathematics is gibberish to you then we many safely
    conclude that you have nothing useful to offer to the groups you
    posted to.

    reCx (xria1 = x)
    reCxreCyreCz (xria(yriaz) = (xriay)riaz)
    reCxreay (xriay = 1)
    reCxreay (yriax = 1)

    is useful for many purposes. But there are sentences like

    reCxreay (xriay = yriax)

    that are undecidable in that system. But there is notiong semantically >>>>> incoherent in that example or similar ones.

    The truth about climate change and election fraud could
    be computed.

    Not without real world information.

    Yes, so what?

    So the biggest problem is not how to compute but how to get and verify
    the relevant real world infomration.

    A set of "atomic facts" does exist. We only nee to write> them all down.

    THat is a lot of work that can never be completed.

    The place to start would be published textbooks.

    How long does it take to read all texbooks published in one year?

    Then peer reviewed papers.

    Now long does it take to read all reviewed papers published in one year?

    Then published newspaper articles.

    How long does it take to read all newspaper articles publised in one
    year?

    And what to do with the "atomic facts" that conflict each other?
    All knowledge that can be expressed in language would
    include the exact (x,y,z) coordinates of every atom of your
    body relative to the exact center of the Earth every millisecond.
    Because this degree of detail is not physically implementable
    to implement my system we exclude most specific details. It
    is a system of general knowledge of about 200 petabytes.

    Of course you may postulate that
    the climate is immutable or that there was massimbe undetected fraud >>>>> in the last or some earlier election but that is not what the word
    "knowledge" means.

    The key elements of election fraud are two things:
    (a) There was no actual evidence of election fraud
    that could have possibly changed the results.

    The key element of elction fraud is to find a vulnerability in the
    election procedure.


    There has only been 1620 total documented cases in the USA
    in the last 30 years. Every investigation into fraud by
    audits found a few more votes against Trump than prior to
    the audit. Each of the 60 election fraud cases Trump lost.
    He lost because his lawyers could not tell the wild stories
    that he was telling the public without getting themselves
    convicted of perjury.

    These these fact were unconvincing seems to prove that
    his supporters are in a cult.

    But not that there were no fraud performed skillfully enough to avoid detection. What was found was only small unintentional errors that
    nobody tried to hide.

    All self-reference "paradox" is equivalent to the
    Liar Paradox and can be resolved by disallowing it
    like ZFC disallowed Russell's "Paradox".

    Whether something is a self-reference depends on interpretation. >>>>>>> In an
    uninterpreted formal language there are no references and
    therefore no
    self-references, which is the simplest way to avoid paradoxes by >>>>>>> self-
    reference.

    Even without any self-reference a theory can be inconsistent.


    Russell's paradox is simply an inconsistency.


    Likewise with all undecidability within the body
    of knowledge that can be expressed as language.

    No, per definition an inconcistency is decidable so it is not an
    undecidability.

    RP is merely the only instance of pathological
    self-reference (PSR) that was correctly rejected.

    Russell's paradox is not an undecidability.


    It was until ZFC refuted it.

    No, it never was. The possibility to decide it was always there. That
    nobody discovered it before Russell is irrelevant.

    The fact is that we did at one time have Russell's
    self reference "paradox" and we no longer has it
    because its incoherence was rejected by ZFC.

    We still have it and its relatives. The naive set theory is still inconsistent. We have ZF and other new set tehories that don't
    have it. Sometimes it would be nice to have an unversal set but
    there is none in ZF.
    HP counter-example input is another instance of PSR.

    The halting problem counter-example is neither an undecidability
    nor an
    incconsistency.

    In computability theory and computational complexity
    theory, an undecidable problem is a decision problem
    for which it is proved to be impossible to construct
    an algorithm that always leads to a correct yes-or-no answer.
    https://en.wikipedia.org/wiki/Undecidable_problem

    There is a note on the top of the page noting that the article needs
    additional citations for verification. This means that the page is
    not as relable as typical Wikipedia pages. In particular, the quoted
    text is not quite correct.

    But the quoted text is irrelevant anyway. In logic "undecidability"
    means that a sentence and its negation are unprovable in some thoery.

    When we switch the proof theoretic semantics then
    unprovable means ungrounded thus meaningless.

    When we use a theory for some serious purpose then inability to solve
    a problem means we must think harder and wider. For example, it may
    turn out that a partial solution is sufficient, or we can determine
    that our soultion method, although not proven correct, works in every
    case we have tested, so we can trust it does not fail too often.

    Going outside of PA in a separate model of PA
    has always only been a mere ruse.

    What we really need to know is not PA but the natural numbers. If
    PA does not answer some question then it is better to look for an
    asnwer elsewhere. A set theory might be a good place because an
    important use of natural numbers is cardinalities of finite sets.


    Thanks for writing. One thing I though to suggest is to consider
    the "deconstructive" approach. For example PA, Peano Arithmetic,
    is usually given as describing a least natural number, then the
    successor function making a case for induction that each following
    natural number exists and is unique under the operation. Since
    that basically is the same thing as cases for induction, it doesn't
    say much about all the body of relation of arithmetic fact.

    So, one might consider the successor operation as alike "increment",
    then the idea that that's the Sumerian concept of an operation on
    numbers. Then, the other basic concept of operations on numbers
    is "partition", or the Egyptians. So, Sumerians start with "addition"
    after "increment", while, Egyptians start with "division" after
    "partition". These are familiar as "positional notation" and
    "continued fractions".

    Then, the idea is that the rationals or the ordered field (since
    the Pythagorean and the Eudoxan, about Pythagoras and Eudoxus,
    then as with regards to their Egyptian and Sumerian influences)
    have addition (and subtraction) and later multiplication (and
    division) as being a field after a group, a different deconstructive
    account can instead make for that it's two groups, one after increment
    (like Peano's, it's just increment the axiom of the operation, not
    quite "addition"), the other after partition.

    So, set theory is plainly a "theory-of-one-relation: elt", or "member".
    That relation "elt" is a binary predicate, vis-a-vis, "contains", or
    "has", which is usually considered the class relation in class theory a "theory-of-one-relation: contains".

    So, familiar with accounts of theories-of-one-relation, "elt" and "has",
    or "member-of" and "contains", then the descriptive account
    relating to numbers (a model-theoretic account) for "increment" and "partition", then help go to show that Peano Arithmetic then later
    for Peano and Presburger about the schema and the orders of the logic
    about addition and multiplication, then make for why it's natural
    to have for "Egyptian-Peano" and "Egyptian-Presburger", why then
    the natural numbers are also as after an account of "Egyptian fractions"
    then on down to "long-subtraction" (or, "long-addition"),
    are for a whole set of whole numbers.

    So, "relations", and, "operations", then about the _modular_, is
    about how many various accounts of numbers, like the Sumerian and
    the Egyptian, come to agree on what looks like counting and the
    rational, and the ordered field, as from the complete ordered field,
    or about: an infinity, and, a continuum.


    Then various accounts of Church/Turing and Church/Rosser and
    Church/Rice are much about the independence of the infinitary,
    for example where the natural integers are compact, or not.

    "Prime at infinity" is a usual enough way to describe that,
    for what's usually given as "the fundamental th'm of arithmetic".

    self-references, which is the simplest way to avoid paradoxes by >>>>>>>> self-
    reference.

    Even without any self-reference a theory can be inconsistent.


    Russell's paradox is simply an inconsistency.


    Likewise with all undecidability within the body
    of knowledge that can be expressed as language.

    No, per definition an inconcistency is decidable so it is not an
    undecidability.

    RP is merely the only instance of pathological
    self-reference (PSR) that was correctly rejected.

    Russell's paradox is not an undecidability.


    It was until ZFC refuted it.

    No, it never was. The possibility to decide it was always there. That
    nobody discovered it before Russell is irrelevant.

    The fact is that we did at one time have Russell's
    self reference "paradox" and we no longer has it
    because its incoherence was rejected by ZFC.

    We still have it and its relatives. The naive set theory is still
    inconsistent. We have ZF and other new set tehories that don't
    have it. Sometimes it would be nice to have an unversal set but
    there is none in ZF.
    HP counter-example input is another instance of PSR.

    The halting problem counter-example is neither an undecidability
    nor an
    incconsistency.

    In computability theory and computational complexity
    theory, an undecidable problem is a decision problem
    for which it is proved to be impossible to construct
    an algorithm that always leads to a correct yes-or-no answer.

    There is a note on the top of the page noting that the article needs
    additional citations for verification. This means that the page is
    not as relable as typical Wikipedia pages. In particular, the quoted
    text is not quite correct.

    But the quoted text is irrelevant anyway. In logic "undecidability"
    means that a sentence and its negation are unprovable in some thoery.

    When we switch the proof theoretic semantics then
    unprovable means ungrounded thus meaningless.

    When we use a theory for some serious purpose then inability to solve
    a problem means we must think harder and wider. For example, it may
    turn out that a partial solution is sufficient, or we can determine
    that our soultion method, although not proven correct, works in every
    case we have tested, so we can trust it does not fail too often.

    Going outside of PA in a separate model of PA
    has always only been a mere ruse.

    What we really need to know is not PA but the natural numbers. If
    PA does not answer some question then it is better to look for an
    asnwer elsewhere. A set theory might be a good place because an
    important use of natural numbers is cardinalities of finite sets.


    Thanks for writing. One thing I though to suggest is to consider
    the "deconstructive" approach. For example PA, Peano Arithmetic,
    is usually given as describing a least natural number, then the
    successor function making a case for induction that each following
    natural number exists and is unique under the operation. Since
    that basically is the same thing as cases for induction, it doesn't
    say much about all the body of relation of arithmetic fact.

    So, one might consider the successor operation as alike "increment",
    then the idea that that's the Sumerian concept of an operation on
    numbers. Then, the other basic concept of operations on numbers
    is "partition", or the Egyptians. So, Sumerians start with "addition"
    after "increment", while, Egyptians start with "division" after
    "partition". These are familiar as "positional notation" and
    "continued fractions".

    Then, the idea is that the rationals or the ordered field (since
    the Pythagorean and the Eudoxan, about Pythagoras and Eudoxus,
    then as with regards to their Egyptian and Sumerian influences)
    have addition (and subtraction) and later multiplication (and
    division) as being a field after a group, a different deconstructive
    account can instead make for that it's two groups, one after increment
    (like Peano's, it's just increment the axiom of the operation, not
    quite "addition"), the other after partition.

    So, set theory is plainly a "theory-of-one-relation: elt", or "member".
    That relation "elt" is a binary predicate, vis-a-vis, "contains", or
    "has", which is usually considered the class relation in class theory a "theory-of-one-relation: contains".

    So, familiar with accounts of theories-of-one-relation, "elt" and "has",
    or "member-of" and "contains", then the descriptive account
    relating to numbers (a model-theoretic account) for "increment" and "partition", then help go to show that Peano Arithmetic then later
    for Peano and Presburger about the schema and the orders of the logic
    about addition and multiplication, then make for why it's natural
    to have for "Egyptian-Peano" and "Egyptian-Presburger", why then
    the natural numbers are also as after an account of "Egyptian fractions"
    then on down to "long-subtraction" (or, "long-addition"),
    are for a whole set of whole numbers.

    So, "relations", and, "operations", then about the _modular_, is
    about how many various accounts of numbers, like the Sumerian and
    the Egyptian, come to agree on what looks like counting and the
    rational, and the ordered field, as from the complete ordered field,
    or about: an infinity, and, a continuum.


    Then various accounts of Church/Turing and Church/Rosser and
    Church/Rice are much about the independence of the infinitary,
    for example where the natural integers are compact, or not.

    "Prime at infinity" is a usual enough way to describe that,
    for what's usually given as "the fundamental th'm of arithmetic".



    Maybe instead of "un-decide-ability" you should frame "independence".
