[topicmapmail] another great logician

[W.M. Jaworski]

Dear Zdzisiu,

The attached text is an answer to one of my questions in the
topicmapmail@infoloom.com list.
So you are "great logician" in the tradition of Tarski, Mostowski and .....
I hope you will still treat me as equal in our next meeting and discussion.
I know that you are very busy, therefore I asked Ziarko to join the list as
"rough sets scholar".

Best regards

Wojtek

PS I still remember your opinion about difference between scholarship and
scientific journalism. Yes, some professors are journalists and some
professionals are scholars.

"Yes I know of Pawlak's wonderful work and have visited
with Professor Zadeh about how the nature of Rough sets is quite different
from that of Fuzzy set theory. Zadeh and I agree that fuzzy set theory is a
means to get out of a category error that involves that assumption that
there is only one reality.  Rough sets (categories) are appropriate to
thinking about emergence and the issues of stratification of reality into
process layers.

Mental interpretation of the meaning of topics arranged in various fashion
is a stratified process in nature.  The formalism to shift scope and thus
the technical means for shifting meaning when XTM is used in practical
situations should (in my opinion) be stratified also.

Poland is recognized as having been the fatherland of yet another great
logician" [Paul Prueitt]
