Kosko struggles to articulate the upcoming paradigm shift from Aristotelian logic to multivalent Fuzzy Logic in the world of commercial technology. He does a good job of explaining the concepts behind the "new" field of fuzzy thinking, but has a hard time expressing the mathematics of it. To give him credit, though, he had to write a book understandable by the lay, and therefore couldn't get too in depth with his equations. But if you have any background in calculus, you'll have no trouble learning from the footnotes.
Aside from the introduction to fuzzy logic, Kosko dips into his personal life to talk about his contributions to the field. I found his digressions extremely interesting and his views enlightening. It's important to take a lot of what he says with a grain of salt, however (he likes to wax philosophical perhaps more than is appropriate), but he is an amiable character nonetheless.
Overall, this is a good read. It's informative not only scientifically, but philosophically as well. Kosko's style is engaging, although too heroic in some passages, and thorough. Because of its controversial nature, some readers may find it offensive. But if you don't mind entertaining alternative opinions and don't mind suspending tendencies for dismissing foreign ideas (which a lot of the people who gave this book bad reviews couldn't apparently handle), you'll enjoy this book.
