隐定义分析性与先验辩护——基于博格锡安进路的重构

Implicit Definition and A Priori Justification—A Reconstruction Based on Boghossian's Approach

博格锡安的讨论使当代语境下关于先验辩护的分析性说明进路得以复活。以他的讨论为基础,卡尔纳普式隐定义分析性理论可被构建为关于语句认识论分析性的统一理论;具体方案是,将语句认识论分析性归结为该语句所扮演的,针对它所包含的某个语词的隐定义这一角色。语句的隐定义分析性特征使得以它所表达命题为其内容的信念满足了认知无咎性条件,并因此获得先验辩护。

In contemporary context,Boghossian's discussion leads to the revival of the analytic approach to a priori justification.Based upon his discussion,Carnap's idea of implicit definition can be constructed as a unitary theory of epistemic analyticity,which characterize an analytic sentence as an implicit definition of some term occurred in the sentence.The belief holding an analytic sentence to be true satisfies the condition of epistemic blamelessness in virtue of the role of implicit definition it plays.Therefore,it is qualified as being a priori justified.
