The cancer treatment that I will have next month has a 5% chance
of killing me and a 1% chance of ruining my brain. It also has
about a 70% chance of giving me at least two more years of life.

Instead of just usual model theory and axiomatics
and "what's true in the logical theory", "what's
not falsified in the scientific theory", you can
have a theory where the quantity is truth, and

And if True(L, x) isn't "well formed" then True fails to meet the requirements of a predicate, so you are just admitting that the required predicate doesn't exist.
If it considers that statement x to be ill formed, and thus return false, then !True(L, x) must be true, or your logic doesn't provide a needed logical operator.
And if True considers a true statement to be not-well formed, it violates your definition, and thus logic fails.

 Then the above expression is simply rejected as not
a WFF of this Comenius language.
And you thus admit that you logic doesn't meed the requirement for the proof.
Yes, you can get rid of incompleteness by hobbling your logic and not allowing it the power to express the required things.
Of course, part of the problem is I belive Comenius was just a philosopher in the broad sense, and not dealing with things in the field of FORMAL logic.

 
As such a statement can't be mapped to True or False without also mapping True to False or False to True.

Note, he shows that such a statement CAN be formed in logic system with certain minimal properties, like being able to express the Natural Numbers and their properties.

So, I guess you are admitting that to you "logic" can't handle something like mathematics.

 The Comenius language expresses the key essence of the most
important aspect of my idea, rejecting expressions that do
not evaluate to Boolean as ill-formed. It only has TRUE
and ill-formed. My system has TRUE, FALSE and ill-formed.
 All undecidable propositions fall into the ill-formed category
and logic is otherwise essentially unchanged.
 
Which isn't an allowed operation for a predicate, Like True, in Formal Logic.
You are just showing that you don't understand how logic works.
Sorry, that is just the facts, you are proving yourself to be a lying idiot.
