Dear Donald:

	Thanks for your letter of 8 Sept.  I didn't remember our
discussion as argumentative.

	Before I can have an opinion on the correspondence between
partially constructed traffic lights and partially constructed
decision trees, I have to get my thoughts in better order about
physical construction.  Maybe I can answer your letter better
later or send you something that may be helpful.  FOL is not
a problem solving system in itself, so eventually we will need
one that has sufficient epistemological generality in the
objects it can contemplate.  Lew Creary here, a philosopher by
background, is thinking about such a problem solver.

	The workshop program looks interesting, and I'll give you
a definite answer by the end of November, but it conflicts with
a meeting in Spain I want to go to on te way to spend May in
Marseille.  I may come but leave on the 24th or evening of 23rd.
