The constructivist sect most familiar to me says, sure,
"it constructs a prime not on the list", but that's sub-
ordinated in the proof to a *reductio ad absurdum*, which
is inherently non-constructive.  That's part of the pro-
gram:  rewriting such formulations in purely
constructive language.  Or am I myself speaking entirely
in anachronisms?  Has modern constructivism somehow come
to rely on the Excluded Middle (something like the Roman
Church and monotheletism)?
