ambigu[f82,jmc]		Ambiguity tolerance and desirable vagueness

	Ordinary language is vague about many concepts.  Philosophy and
science have found it necessary to develop precise terms that roughly
correspond to many of these concepts, but developers of common sense
reasoning systems should consider whether at least some of this
vagueness and ambiguity is useful.

	One class of such ambiguities concerns the identity conditions
for terms used as predicates.

1. Conspiring to assassinate a federal official.

2. IBM wants.  The U.S. wants.  George wants.

3. quantity of motion.  Use Lomonosov pre-theory of conservation as
an example of a vague concept.
