A formula becomes a truth‑bearer       only when PA can classify it in finitely many steps.       Goldbach may or may not be classifiable; that’s an open       computational fact, not a semantic requirement. This has       no effect on Gödel, because Gödel’s sentence is structurally       non‑truth‑bearing, not merely unclassified.              >>       >> When we change the foundation of formal systems       >> to proof theoretic semantics and add my truth       >> predicates then Gödel's claim of applying to       >> every formal system that can do a little bit of       >> arithmetic becomes simply false.       >       > But you CAN'T do that and keep the systems.       >              I am keeping the systems.       I’m changing the semantics.       PA’s syntax, axioms, and rules stay exactly       the same. What changes is that truth is internal       - finite derivability - and external model‑theoretic       satisfaction is no longer imported into PA. Gödel’s       claim depends on that external semantics, so once it’s       removed, his universal claim simply doesn’t apply.              >>       >> Every attempt at showing incompleteness |
