Excerpt from letter from Pat Hayes to Bruce Anderson  10 Feb 1973

	I'm working towards a paper to send to the special 1974
representation-theory edition of the AI journal.  I bet JMC is
also aiming at that: yes?

	Tell John I know I owe him a letter and its on my stack 
of things to get done.  Tell him teaching is horrible and research
is difficult.  Tell him that what I want to say  to him about
representation & our paper is basically that we need to distinguish
	(1) knowledge of the world
	(2) knowledge of problem-solving
	(3) the interpretive machinery which infers.
and that the "heuristic/epistemological" stuff blurs the distinction
(2)/(3), which is a pity.  And that one of the points of the 
distinction (2)/(3) is that (3) BELONGS IN THE SEMANTICS OF THE
LANGUAGE WHICH EMBODIES (2) ← which is one that Hewitt missed!

	Tell him also that if he puts that in his paper before I get
mine written, I'll kill him.
