Yo!

Fuzzy logic doesn't use Boolean logic, at least not at the level of the
'fuzziness'; boolean logic is a restricted subset of fuzzy logic. Fuzzy
logic also does not produce piecewise linear approximation.

Trying to understand fuzzy logic by figuring out a model of how it works
based on other logical systems is largely futile. It leads to that
sinking feeling that there isn't really anything there. This has misled
quite a few otherwise sharp guys, including one of the real heros, Bob
Pease from National Semiconductor.

You have to try to understand the definition of fuzzy logic in its own
terms. This means that there are no obvious applications until you can
recast your problems into those terms. When you accomplish that, you
will see that there are whole classes of problems that are difficult or
intractable using standard methods that fall out elegantly using fuzzy
logic. In the end, it becomes just another handy tool in your kit of
tricks.
