Fuzzy Thinking

Western thinking is based on Aristotle ... around 2000 years old. So much of our logic and decision making depends on True/False or Yes/No Decisions. Are you tall or short? Do you like your Job - Yes or No? Such questions have answers indicating different levels of truth.

Lotfi Zadeh was the pioneer worker in the area of Fuzzy Logic (Fuzzy Thinking) and his work has been made accessible to the public in two books:

Fuzzy Thinking by Bart Kosko

Fuzzy Logic - The Revolutionary Computer Technology that is changing the world by Daniel McNeill and Paul Freiburger.

Although the main application of Fuzzy Logic has been in process control (train controllers, air conditioning, control of nuclear reactors, etc), the principles are important to the understanding of how we think. I believe it is as important as Edward de Bono's book "Mechanism of Mind".

How would you decide to change jobs or propose marriage? Answers to questions such as "Is the Salary Good?", "Can we be happy" will have varying degrees of truth. In Aristotelian Logic, there is True and False. With Fuzzy Logic, there is a scale of 0 to 1 where Truth would be 1 and False be 0. Decisions made with Fuzzy Logic take into account these varying degrees of truth for a variety of inputs, and produce an output (action) based on the inputs.

This section of the Creativity Web is being developed so your thoughts on Fuzzy Logic and Fuzzy Thinking are most welcome!
