现代西方哲学家论模糊性的本质

On the essence of fuzziness in the light of western contemporary philosophers

伴随现代西方哲学的“语言的转向”, “语言的模糊性”得到深入探讨。皮尔斯是西方哲学史上确认“语言本身的模糊性”的第一位哲学家; 维特根斯坦强调语言确定性与模糊性的并存关系, 并试图将二者统一; 罗素从符号逻辑的水平上首次打破了古典逻辑的排中律, 开辟了形式化模糊逻辑或多值逻辑的研究道路。

A profound discussion on “ the fuzziness of language ”followed “ the shift of language ”in western contemporary philosophy. Peirce was the first philosopher who confirmed the fuzziness of language itself. Wittgenstein emphersized the coexistence of fuzziness and exactness in the language, and tried to unite them. Setting out from symbolic logic, Russell was the first philosopher who destroyed the law of excluded middle in classical logic, and provided leads for the research into formalized fuzzy logic or multi-valued logic.
