Dear Bert:

	Enclosed is an abstract of a paper I plan to give at the
Vancouver conference on artificial intelligence and philosophy.
I have taken your term `ambiguity tolerance' for something
I am trying to formalize.  I have not yet reread your book to
find out whether I owe you more than the name.  However, my reaction
to John Haugeland's old paper in BBS was that some of the problems
mentioned for AI were one's whose solution was necessary, and it
may be that I will find that your discussion of `ambiguity tolerance'
mentions specific properties that must be formalized.

	Most likely, I will not be able to fulfill all the promises
made in the abstract, as I have found good examples harder to find
than I expected.
