It has basically evolved from predicate logic, though many forms called t-norm fuzzy logics do exist in propositional logic too. It generally has an object and a predicate. For example: in the sentence, “Plato is a man”, ‘Plato’ is the object, and “is a man” is the predicate. But an important point about fuzzy logic is that it is deterministic and time-variant. A few salient points explained by Zader Lotfi on fuzzy logic are:
The roots of date back to the time when intelligent life forms evolved and they all can be classified as fuzzy systems. While Aristotle, presented the system of two valued logic, it was Plato who laid the foundations of what would be known as fuzzy logic by proposing that there was an intermediate third region in between ‘true’ and ‘not true’ where some part might be true, while some part might not be.
