And so True(L, x) must be false, and thus we are saying that x, which is 
defined to "not True(L, x)" must be true, so not only are you wrong 
about it not being a truth bearer, you are wrong about not being true.

Or, does your logic say that "not false" as a logical expresion isn't 
true? and thus your logic fails to hold to the rule of the excluded middle?

And "True(L, x)" needs to return True if x is True, and False if x is 
False, or not a truth bearer.

So, since x defined as "not True(L,x)" is True if True(L, x) says no, 
then True failed to live up to its requirements.

And you show you are unable to understand what requirements are.

So, you think the Goldbach's conjecture IS true? Show your proof and win 
the prize,

But there are MANY such statements, so you are just admitting that your 
theory is just full of holes.

No, it isn't the case that the VERBAL meanings have anything to do with it.

It is the FORMAL meanings, defined in the system that define it.

And Infinite Chains genrate semantic truth.

Also, just because something is true in a "verbal model" of the world 
doesn't make it true in a given formal system.

But formal systems do not need to be "accurate models of the actual 
world", and what Quine was pointing out was that natural language is 
inherently a bad model as words can have too many different meanings.

Then go in and get out of Formal systems. The rules are different, and 
what works in one place doesn't necessarily work in the other.

Nope, that is a LIE, and shows your ignorance, and that your foundation 
of anaklytc truth just can't handle the logic.

You just admitted that there were statements you "truth-maker" logic 
can't handle, because they need infinite steps.

So, now it seems you are saying that there are statements with actual 
truth value of true or false that are not "truth-bearers", in other 
words, you are admitting you definition is a self-contradiction.

You mean you have MISUNDERSTOOD It for two decades.
