I respond to defend the accuracy of (what Steve has quoted above from) my
recent posting to the FOM. It was not misleading.
To my knowledge, there was no discussion of Simpsons' personal and
professional shortcomings - privately or publicly - other than the damage,
in my view, that has been caused by the, in my view, completely unnecessary
and inexplicable delay in the republication of SOSOA, which has been
unavailable for several years. The exception is that my discussions with
Steve were more candid, and touched on the nature of his commitments.

When I was present, the only timetable stated in Steve's talk (and elsewhere
as far as I know) was the assertion that the book would be submitted to ASL
for republication "when I (Steve) feel like it". I do not think that this
quote represents a "definite timetable", the phrase used in the passage that
Steve quotes above from my previous posting. My statement is accurate.

This book was submitted by Steve a few years ago to the ASL, and has been
mentioned frequently on the FOM already. I have two papers in that volume,
and have always been pleased that this volume was eventually submitted to
the ASL, even though the call for papers was made by Steve in 1999.

I can't see how anyone would think that I am a spokesman for anyone else in
mathematical logic. However, I am an interested party when inexplicable
delays occur that, in my view, do damage to Reverse Mathematics. I first
seek to understand the cause of such inexplicable delays, and then seek to
remedy such delays.
Given my perceived hopelessness of the situation, I have taken some initial
steps towards identifying a coauthor or coauthors for publication of a book
"Elements of Reverse Mathematics" which should serve as an available text
for courses in Reverse Mathematics. The intention is that it will focus
entirely on RM and not include dispensable material on subsystems of second
order arithmetic. There will be no attempt to be comprehensive, and the book
will be considerably shorter than SOSOA. It will also include material on
some newly developing dimensions of RM, which I call SRM (strict reverse
mathematics). These newly developing dimensions were discussed in some
unpublished manuscripts of mine from the 1970s.
