Fuzzy logic is simply a multi-valued logic; and it is not the only one,
although quite popular (and successful) in a number of fields, like
pattern recognition, vision, XPS, NN, process control....

Fuzzy logic has nothing to do with probability, except for the fact that
the range of truth values are usually taken from the interval [0,1].
On the contrary, it is _dangerous_ to think of fuzzy variables as of 
random variables, because both the concepts and the operators are
quite different. 

It seems like somebody should post a tutorial.... so little time.
