中文摘要：

说谎者悖论看似简单,但对其解决却极其艰难。此外,说谎者悖论的解决也不仅仅是关涉悖论领域的各种基本问题,比如悖论的界定、悖论的特点,尤其是解悖方案的功效等等,而且还上升至逻辑的基本问题,比如逻辑矛盾、逻辑语义学等问题,甚至还上升至哲学问题,比如真理理论、意义等问题。而矛盾问题则是各种问题的纽带,是从悖论到逻辑、再从逻辑到哲学上的关键环节。就此而言,情境语义学对于说谎者悖论的解决,其意义不仅体现在解悖方案的有效性方面,更体现在对于逻辑矛盾的重新界定方面。

英文摘要：

The liar paradox is seemingly simple, but it is very difficult to solute it. In fact, how to solve this problem is connected with all kinds of basic questions in the field of the paradox, such as the definition of paradox, the specialty of paradox, especially the solution scheme of efficacy, etc.. It may be risen to logical basic problems, such as logical contradiction, logical semantics, and even risen to philosophical questions, such as theory of truth and meaning. The problems of contradictions is the core of all sorts of problems, from the paradox to logic, and then from logic to the basic problems of the philosophy. In this respect, It is significant to Situation semantics solution to the liar paradox： it is not only reflected in the solution scheme of effectiveness, but also in redefinition for logical contradiction.
