Dear Abby.  My friends are shunning me because i think that to call
a program an "expert system" it must be able to explain its decisions.
"The system must be able to show its line of reasoning", I cry.  They
say "Forget it, Roy... an expert system need only make decisions that
equal human experts.  An explanation facility is optional".  Who's
right?

Signed,
