• How Saul Kripke provided the foundation for a consistent and correct truth predicate

    Any system of reasoning that begins with a consistent
    system of stipulated truths and only applies the truth
    preserving operation of semantic logical entailment to
    this finite set of basic facts inherently derives a
    truth predicate that works consistently and correctly
    for this entire body of knowledge that can be expressed
    in language.

    A truth predicate as defined above is only applicable to models
    of the system. It does not apply to non-model interpretations.

    There is no theoretical reason why the above system
    architecture cannot derive a consistent and correct
    truth predicate for every element of the body of
    knowledge that can be expressed in language.

    It is the entire body of knowledge that can be
    expressed in language and has full natural language
    semantics formalized as something like Rudolf Carnap /
    Richard Montague meaning postulates.

    basis to pick one of those predicates as "correct".

    The problem still remains that the language that can express the
    meaning of the truth predicate is not in the domain of the predicare.

    Yes if you don't pay complete attention it may seem that way.
    Go read and re-read the first paragraph a few dozens times
    it took me 28 years to come up with it.

    The problem still remains that the language that can express the
    meaning of the truth predicate is not in the domain of the predicare.


    Sure it can when a single language can encode different
    orders of logic. MTT has extended FOL syntax and the ability
    to encode arbitrary higher orders of logic in the same
    syntax. An example of SOL is provided.

    Kripke's text can be understood in a time much less than 28 years.
    In particular, Kripke is very clear about the infinite chain of
    theories. Kripke is also clear and right about Tarski's result.

    Its been 21 years since I looked at it.
    I was going by the AI analysis of how he conquered
    the Liar Paradox.

    If he said this he was wrong. There is only a finite
    number of levels of logic to encode all human knowledge
    that can be expressed in language. Knowledge of infinities
    is algorithmically compressed.

    I am going by the AI analysis that was nearly the
    exact same system as mine. Start with a consistent
    set of stipulated truths then only apply the truth
    preserving operation of semantic logical entailment
    then the liar paradox remains undefined because it
    cannot be derived.

    I am trying to give Saul Kripke credit there credit
    is due on the basis of the AI analysis.

    There is only a finite number of levels of logic to encode all
    human knowledge that can be expressed in language.

    A truth predicate that would cover all those levels cannot be expressed
    in the language of any of those levels.


    Sure it can. Here is how I do it: https://www.researchgate.net/publication/331859461_Minimal_Type_Theory_YACC_BNF

    The first page shows how to encode SOL in FOL syntax
    using the := operator. There is no fixed limit to this.
