When I joined this list, I hoped to stay out of the religous wars...

Andy, you and Bob Pease (National Semiconductor/Electronic Design Magazine)
must be good buddies! He relentlessly blasts those who pray to the fuzzy gods.

When I took circuit analysis, the professor (Professor Carlin) said there are
two ways to do circuit analysis:

1) His way, i.e. Logic, Reason, and old-fashioned Thinking

or

2) The Hope, Guess, and Pray method.

In reality, and only in reality, this method applies to everything.

There is absolutely nothing wrong with fuzzy logic per se; as long as you
 understand
its mathematical basis and consequently its strengthes and weaknesses. The
 problem arises
when one's premise is that product xyz is good because "fuzzy logic" has been
used in its development. BS.

A similar situation exists for so called "Neural Networks". If you get right
 down to it,
Neural Networks are no more than adaptive FIR (Finite Impulse Response) filters.
 There's not
much similarity between a Neuron and a digital filter. Similarly, there's not
 much similarity
between fuzzzy logic and human reasoning.

You never can replace thinking and good design techniques!


May the fuzzy gods have mercy on my logic.
