摘要
在含糊性问题研究领域,多值语义解释和超赋值语义解释是两个经典的研究进路。相较多值语义中的经典三值解释和基于概率赋值的模糊逻辑解释,范启德(1975)给出的超赋值语义由于引入了基于可能世界语义的可精确化结构,具有更强的表达力,能够弥补三值和模糊逻辑处理的很多不足。距离超赋值语义发表40余年后,秋叶研(2017)给出了同样满足可精确化结构条件的一个布尔多值解释。由于超赋值语义一直被当作典型的内涵语义处理方式,而在含糊性问题研究领域,布尔多值方法却在大多数时候被认为是模糊逻辑这个基于概率处理的典型的外延语义的复杂版本,内涵语义与外延语义的殊途同归,非常值得仔细思考和探究。本文将结合含糊性问题研究领域的多值语义解释和超赋值语义解释的演进过程,以内涵语义和外延语义的区分为切入点,最终指出,(当下主流定义下的)内涵语义与外延语义的界限是模糊的,而在原有界定基础上,对内涵语义增加“内涵语义要可以表达非线序的偏序结构”这一限制,能够进一步对内涵语义和外延语义进行区分。
Manyvalued semantics and Supervaluation semantics are two classical approaches in the field of vagueness approaches.Compared with the classical Threevalued interpretation and the Fuzzy logic interpretation in Manyvalued approaches,the Supervaluation semantics given by Fine(1975)has stronger expressiveness,which is due to a modal precisificational structure are introduced by Fine in his work.About 40 years after the publication of Supervaluation semantics,Akiba(2017)presents a Booleanvalued interpretation that also satisfies the conditions in a precisificational structure.Since Supervaluation semantics has always been regarded as a typical approach with intension semantics,while in the field of vagueness research,Booleanvalued methods are mostly considered as a complex version of Fuzzy logic,a typical extension semantics based on probability processing,it is worthy of careful consideration and exploration that both intension semantics and extension semantics lead to the same destination.Based on the development of Manyvalued semantics and Supervaluation semantics on vagueness approaches,this paper takes the distinction between intension semantics and extension semantics as the starting point,finally points out that the boundary between intension semantics and extension semantics(under the current mainstream definition)is vague,while partial order structure and linear order structure are more essential distinctions.
