Date had it right. NULL is neither true nor false.

The most fundamental problem of constructing any kind of knowledge in a
space as large as the internet is heterogeneity. The most fundamental
strength when working with heterogeneity is knowing what you don't know.

If I remember anything from my few years in biochemical research, decades
ago, is that the most important attribute of the alert researcher of complex
systems is to look for what is not identical in "identical" attribute sets
that do not yield identical results. Usually this goes back to re-examining
the attributes that everyone *knows* are unimportant or identical.

I guess these are three parallel statements that I find Pat's last two
letters appealing and esthetically correct, and that I find his defense of
non-monotonic logic compelling

As a new-comer in the semantic space, what is CL, where should I start to
read on it.
