But is the meta-theory *about* PA, itself classified as either PA or
'Arithmetical truth' ? The meta-theory itself (when enacted as a
computation) cannot be classified as either, it seems to me. So it
appears there's a third category which is neither arithmetic
(descriptions) nor Arithemetic (platonic truth). And recognizing this
third category is the solution to the puzzle of reflection OK!
