Re: SUO: Plea for Relements
Jon,
There is a very big difference between fuzzy logic and
fuzzy sets. I approve of fuzziness in set membership,
but not fuzziness in truth value.

The Lotfi one first invented fuzzy set theory and later
extended it to fuzzy logic. Most of the useful applications
of fuzziness use fuzzy set theory -- not fuzzy logic (which
I criticize as an example of the fallacy of misplaced fuzziness).
