FOM: Constructive v. Nonstandard Analysis, and rapprochement

In an off-list exchange on the subject of rapprochement, I mentioned to
the moderator the symposium in Venice last May on  nonstandard and
constructive analysis (entitled 'Reuniting the Antipodes: Constructive and 
Nonstandard Views of the Continuum', and attended by several subscribers to FOM).  
He asked me to give a report on that conference to this list.

Instead, let me just (a) give a pointer to the apparently-still-alive
web site:; and (b)
suggest that people keep an eye open for the conference proceedings,
which is under construction.

It is worth mentioning - for those who are unaware of this - that there
has traditionally been a split between these two areas on both a
mathematical and social level. The conceptual split is clear:
nonstandard analysis is a branch of classical mathematics, so is subject
to the usual criticisms of the constructivists. However, a non-
technical split was incited some years ago by an unnecessarily nasty
attack on one of the areas by a leading practitioner of the other. This
conference actually addressed both splits (with some success), which is why it seemed
to me to be relevant to recent events on the FOM.
