同一替换律失效原因及解决方案剖析

Analysis of the Reason for and Solution of the Invalidity of Identity Replacement Law

一般而言,在普通语境下,指称相同的表达式之间是可以相互替换的。而在间接语境中,同一替换律就会失效。针对这一问题,弗雷格和罗素分别对其原因进行了分析并提出了各自的解决方案。文章首先对他们的相关理论和解决方案进行了述评,然后从语言使用策略的视角,提出了自己的解决思路。

Generally speaking, the expressions which have the same reference can replace each other in the common context while in the indirect context this indentity replacement law will become invalid. Frege and Russell have studied it and put forward their own solutions. This paper presents a general description of their related theories and their solutions, and then put forward our own solution from the perspective of language use strategy.
