Sure he did. Using a mathematical system like Godel, we can construct a statement x, which is only true it is the case that True(x) is false, but this interperetation can only be seen in the metalanguage created from the language in the proof, similar to Godel meta that generates the proof testing relationship that shows that G can only be true if it can not be proven as the existance of a number to make it false, becomes a proof that the statement is true and thus creates a contradiction in the system.

That you can't understand that, or get confused by what is in the language, which your True predicate can look at, and in the metalanguage, which it can not, but still you make bold statements that you can not prove, and have been pointed out to be wrong, just shows how stupid you are.

Note, "The Entire set of Human General Knowledge" does not contain the contents of Meta-systems like Tarski uses, as there are an infinite number of them possible, and thus to even try to express them all requires an infinite number of axioms, and thus your system fails to meet the requirements. Once you don't have the meta- systems, Tarski proof can create a metasystem, that you system doesn't know about, which creates the problem statement.

And, even if it does detect it, what answer does True(x) produce when we have designed (via a metalanguage) that the statement x in the language will be true if and only if !True(x), which he showed can be done in ANY system with sufficient power, which your universal system must have.

Unless you bother to pay attention to the details
of how this of encoded.

But "Encoded Knowledge" isn't a logic system. PERIOD. BYU DEFINITION. That would just be a set of axioms. Note, Logic system must also have a set of rules of relationships and how to manipulate them, and that needs more that just expressing them as knowledge.

Part of the problem is that most of what we call "Human Knowledge" isn't logically defined truth, but is just "Emperical Knowledge", for which we

Of course not, as then True(x) just can't handle a statement whose truth is currently unknown, which it MUST be able to handle

 The actual smell of a rose cannot be expressed using
language.

Maybe, depends on your definitions. Of course, part of the problem is that the "smell of a rose" is actually a subject thing, so not directly related to knowledge. Of course that concept blows apart large parts of your theory. Much of what is commonly called "Human Knowledge" isn't actually knowledge, but subjective opinions that have been agreed by the majority, and thus not actually something that can be handled by objective logic.

 

know it isn't totally accurate (as all measurements have error) or is actually just an approximation for what reality actually is.

 You simply did not bother to pay any attention to any details.
We simply formalize the entire body of human general knowledge
as one gigantic tree of knowledge semantic tautology using
Montague Grammar and knowledge ontology inheritance hierarchy.

Which isn't a logic system, BY DEFINITION, it is a knowledge ontology.

 If those are all words that you do not understand that does
not mean that I am wrong.
 

Of course it does, since apparently you don't understand what LOGIC actually is.
