beeson.not[s85,jmc]	Comments on Beeson's paper on knowledge

	The paper is written clearly enough, but the formalism
is incompletely developed and seems vague.  Nevertheless, the
following comments can be made.

1. The proposed formalism is too procedural to represent human
common sense knowledge.  The procedures cannot use additional
facts that may become available and relevant if they aren't
built in.  In the restaurant example, suppose Luigi comes to
the door and says that the restaurant opens in five minutes.

2. As long as all the exceptions have to be built into the
rule in advance, there is no significant difference from
putting the negations into the positive part.  I'm not sure
of the role of always having and ELSE part.
