克里普克《真理论纲要》一文批评了塔斯基的经典解悖方案,提出了解决悖论的新方案,在语义悖论乃至整个悖论研究中产生了重要影响。通过剖析克里普克解悖方案的3个核心概念——“真值间隙”、“有根性”、“固定点”,有助于我们深入探讨悖论语句的特点。通过与塔斯基经典方案的比较,可以发现克里普克解悖方案在技术上和直观上的优点。
S. A. Kripke published an important paper named Outline of a Theory of Truth in 1975, in which a new solution to the semantic paradoxes was proposed and the orthodox approach of Tarski was criticized. The proposal has greatly stimulated the research on the semantic paradoxes. Through detailed analysis of the core concepts of this paper, namely, Truth-value Gaps, Groundedness, and Fixed Point, Kripke' s viewpoint can be understood better. In further comparison with the Tar,ski' s classic approach, it is found that the Kripke' s proposal has technical and visual advantages.
