First, as a concrete example use instead the much simpler
(x)(Nx => Ex Sxy) .
Then this a theorem of PA, since it is an axiom of PA. It would not,
however, be provable in the systems of which I speak.
Anyway, I'm not quite sure what essential falls away if PA proves
propositions which are not true.
