"Bart Kosko, the leading proponent of fuzzy thinking, has degrees in philosophy, economics, mathematics and electrical engineering but even in his book there is a clear-cut thesis that ties all this complex thinking together: to explore the paradigm shift from black and white to gray, from bivalence and binary (either/or) thinking to multivalence, a less simplistic but more accurate way of thinking that responds to life in matters of degree, integrating probability and ambiguity in all modes of operation. (Kosko, Bart. Fuzzy Thinking. New York: Hyperion Press, 1993.)
Fuzzy thinking demands that you increase your options. What are all the possible things or events or conditions that could occur as you explore something? You must use your imagination much more actively than usual. Fuzzy thinking comes from fuzzy math sets in which endless possibilites have been explored. So to unite fuzzy thinking with traditional logic, you need to know more, feel more and think more exhaustively.
Perhaps the word "fuzzy" is misleading for undergraduates. Gratuitous ambiguity due to laziness is not the goal, but rather an inclusion of degree, probability and ambiguity in the formulation of structures that respond to phenomena. In other words it is harder and more intellectually demanding to engage in fuzzy thinking. Kosko has a thorough understanding of traditional logic and its fallacies as well as all the specific scientific applications of fuzzy thinking.
Traditional logic, with all its artificiality, is based on language, but the irony is that the flesh of language is our bodily experience, the cries and sighs and gurgles of needs and wants that slowly grow into more complex sounds that usually connote more than they denote. Nature constantly speaks a language that is homospatial and homotemporal, layered and nonlinear in space and time, and this language still resides in our subconscious world of dreams. While expository writing necessitates so-called logical, grammatically correct sentences that grow into coherent, well-developed paragraphs integrated by a thesis, this type of writing should not exclude the multivalent nature of experience, of our bodies, our dreams and our environments. Clarity in expository writing is important so you must redefine words in the context in which you are using them but it's okay to struggle with solutions, to end with answers and to obfuscate a cause-effect relationship with a provocative "what if?"

Hearing someone say my Twitter and Tumblr username out loud is pretty much a spiritual experience.
Oseman, A. (2018). I was born for this. HarperCollins Children’s Books.
I can't overstate how much this quote means to me. So many years ago I came up with the username Leapfrog for a wiki page. It's based on a method used in numerical analysis and it is used in numerical weather prediction models, which is what I was working on at the time. Not much later, I started my first public social media profile, but Leapfrog was already taken. So I added Fuzzy. It's based on fuzzy logic, so again something I was just learning about. Whereas Boolean logic is based on only two truth values,
Fuzzy logic [...] is a special many-valued logic which aims at providing formal background for the graded approach to vagueness.
Novák, V., Perfilieva, I., & Močkoř, J. (1999). Mathematical Principles of Fuzzy Logic. Springer.
That is how I became FuzzyLeapfrog, or simply Fuzzy.
Both words capture my nature and soul very well. I always try to find a numerical solution, while acknowledging that the world is more complex and vague than that.
So I've been called Fuzzy online for over a decade now, but gradually Fuzzy has also found its way into offline interactions. It's not just about me though. So many people I meet offline are people I met online and we very often address each other with our online names anyway. This has brought me so much joy and probably caused a lot of confusion for people who are unfamiliar with our online names or even the concept of online names.
Anyway, it doesn't matter how often I hear it, having someone acknowledge our online connection by calling my Fuzzy loudly offline is an endless source of inner joy. I am Fuzzy.
