   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))

              My 28 year goal has been to make
       "true on the basis of meaning expressed in language"
       reliably computable.

              This required establishing a new foundation
