  Just to reply to one question, which will suggest the replies to the
other issues:    (01)

>> How many times do we have to keep repeating the obvious?    (02)

  In the present case, it seems that you will consider it necessary
when you choose to misinterpret my comments.    (03)

Pat,    (06)

We've gone over this issue again and again over the past
many years:    (07)

And we've always come back to exactly the same answer:    (09)

  1. Yes, it is possible to have a large umbrella ontology,
     *provided that* it has very few detailed axioms.    (010)

  2. But all detailed axioms must be put into the special
     purpose theories that enable detailed reasoning for
     specialized applications.    (011)

Every accepted theory in science is an *approximation* --
that is the fundamental principle of science -- everything
that we think we know is potentially falsifiable.    (013)

PC> ... theories useful in particular circumstances, not as

Please write the following statement on the blackboard (or
the whiteboard) one thousand times:    (015)

    There is not and never will be a final and only model of reality.    (016)

How many times do we have to keep repeating the obvious?    (017)
