论克里普克的“后验必然命题”

On Kripke's Posteriori Necessary Propositions

克里普克提出的后验必然命题,指的是那些不能独立于现实世界的经验而得知其不可能不为真,且在形式上一般由两个严格指示词所组成的命题。克里普克对于这类命题的论证,可以重构为"同一对象的必然性"、"后验必然命题的必然性"、"后验必然命题的后验性"、"后验必然命题的偶然性幻觉之缘由"四个步骤。克里普克的严格指示词理论是其后验必然命题的核心和依托。

Kripke’ s posteriori necessary propositions are not impossibly true propositions that we could know their truth based on our experience in real world , and commonly consists of two rigid designators .The argument on these propositions could be reconfigurable with four procedures： the necessary of the same object , the necessary of posteriori necessary propositions , the posteriori of posteriori necessary propositions , the Contingency illusion of posteriori necessary propositions .Rigid designator is the core and ground of posteriori necessary propositions .
