In his reply to my "on harvey friedman's number theorists" of 8 April,
Timothy Chow begins by quoting something I say in it.

Tim, you're talking about "effective" and "computationally efficient"
methods. That's great stuff. I'm with you. But, as I understand it,
Harvey is insisting that every bound is, as he puts it, "intrinsically"
interesting. Every bound.
And even if he doesn't really mean this, he's made it clear that he
does mean it for every bound for a "pure existence" theorem in number
theory. Every one. (I don't know how he feels about this outside of
number theory. I've proved more results of this kind than I care to
remember, including at least one in number theory, but the earth never
moved. My reasons for proving them were *not* what I called "sound
