There is no reason to dismiss fuzzy logic, fuzzy sets, and all
related science & technology. Indeed, a lot of good work gets
done everyday by means of fuzzy logic (using the term in general).

Maybe I should not have answered the question, because I am
not a critic of fuzzy logic :-)

Maybe, it would be more useful if we were to concentrate on
more practical issues. For instance, how do we deal with
the "curse of dimensionality" and with the "explosion of
number of rules"?

I am not criticising your posting, Will. I have read a lot of
your past postings and always liked them. I know that you
are a serious guy. I am just writing about the fact that after
so many years we still have to justify ourselves for using
a "multi-valued continuous logic" that unfortunately has
been called "fuzzy logic".

Best regards

Bruno
