Fuzzy logic

In this study, it will be stressed that how is reached to the fuzzy logic notion with the logic, which is the handling of human reasoning and decision-making processes in terms of reasoning, logic, and mental activities and, logic-language relation and the theories of new physics.At the first part of this study we investigated the two valued classical logic and symbolic logic. At the second part with logic in terms of Science and mental activities in the context of Language, Thought and Mathematics, we also evaluated new physics research providing the emergence logic as a paradigm shift and as a result theories of quantum physics which was put forward. After that part, considering the fuzzy logic at the conceptual view we investigated the general characteristics of fuzzy logic system and the philososphical changes it makes in our thoughts. Besides we give some information about the practical usage of fuzzy logic notion in the field of technology.Key Words :Logic, Syllogism, Fuzzy Logic, Quantum Physics, Language and Mind
