Instead of "taking Shoenfield seriously", I should have said "taking
Shoenfield's comments on formalization seriously".  This is what I
intended.  My intention was probably clear from the context, but
I don't want to leave any doubt.

By the way, I still don't understand Shoenfield's suggestion to extend
Harvey's independence results in analogy to the Martin/Steel/Woodin
theorem concerning projective determinacy.  Could somebody please tell
me, did Shoenfield have a specific conjecture in mind, or even a
glimmer of one?  Perhaps he didn't, and his only purpose was to, as he
said, "encourage Harvey" by dangling the Karp Prize in front of him.
But if Shoenfield did have a specific f.o.m. conjecture in mind, I'd
like to know what it was.
