Washing machines that sense dirt levels and adjust cycles.
Subway trains in Sendai, Japan, that use fuzzy controllers for smoother braking and acceleration.
Beyond engineering, Kosko delves into the philosophical shifts required to accept fuzzy thinking. He suggests that Western culture is deeply "all-or-nothing," which leads to rigid thinking in politics, law, and ethics. By adopting a fuzzy worldview, we recognize that "truth" is often a sliding scale, which can lead to more nuanced and tolerant perspectives. Science and "Entropy" Bart Kosko Fuzzy Thinking: The New Science of F...
The essay highlights how fuzzy logic transitioned from a fringe mathematical theory (pioneered by Lotfi Zadeh) to a practical engineering tool. Kosko discusses its successful application in:
Kosko posits that while binary logic works for mathematics and digital computers, it fails to accurately describe reality. He points out that most concepts are matters of degree. For example, at what exact point does a "tall" person become "short"? Binary logic demands a sharp cutoff, whereas fuzzy logic allows for a person to be "70% tall." The "Fuzzy" Revolution Washing machines that sense dirt levels and adjust cycles
In his 1993 book, Fuzzy Thinking: The New Science of Fuzzy Logic , Bart Kosko challenges the traditional Western reliance on "binary" or "Aristotelian" logic—the idea that everything is either true or false, black or white, 1 or 0. Kosko argues that the real world operates in shades of gray, and that embracing this "fuzziness" is essential for both scientific progress and understanding the human condition. The Problem with "Either/Or"
Fuzzy Thinking serves as a manifesto for a "gray" world. Kosko’s work encourages us to stop forcing the world into boxes where it doesn't fit and instead use the mathematical tools of fuzzy logic to navigate the inherent ambiguity of life. He suggests that Western culture is deeply "all-or-nothing,"
