      [continued from previous message]              Truth in PA is proof‑theoretic. These were historically       conflated only because proof‑theoretic semantics did not       exist. With Curry’s notion of internal truth, PA’s truth       predicate is simply:              ∀x ∈ PA ((True(PA, x) ≡ (PA ⊢ x))       ∀x ∈ PA ((False(PA, x) ≡ (PA ⊢ ~x))                     --       Copyright 2026 Olcott |
