But Truth *IS* Truth, or you are just misdefining it. The fact that a system can't tell you the truth value of a statement doesn't mean the statement doesn't have a truth value. And, the problem is that, as was shown, systems with a truth predicate CAN'T support PA or they are inconsistant.

No, he shows that any system that support PA and a Truth Predicate is inconstant. It seems you just want to let your system be inconsistent, as then you can "prove" whatever you want. > > PA can prove statements, but it cannot assert that > those statements are true. Those are different notions. Right, but statments in PA can be True even without such a predicate. The issue is we might not be able to know if a given statement is true. As Tarski showed, Add a Truth Predicate to PA and you get an inconsistent system, that is why he says there can not be a Truth Predicate in such a system, as inconsistent systems are really just worthless. > >> Your problem is that your "Truth Predicate" forces either you system >> to be "trivial" or "inconsistant". >> >> But, you are too stupid to understand this. >> >> Your own system requires that which you call non-well-founded, so it >> is itself, by your definition, not-well-founded. >> >> The problem is, except in trivial systems, we can't actually tell if a >> statement is well founded until we determine its truth, and may >> declerations of not-well-founded are themselves not-well-founded. >> >> You can only call Godel G statement not-well-founde by accept that it >> is true and unprovable, you can not otherwise PROVE that it isn't >> well- founded. > >
