【摘要】：悖论是从看似为真的前提经过看似不可反驳的推理得出形如P∧劭P或P圮劭P的公式。这个公式只是一个语形上的矛盾形式,它本身并不就是一个问题。这种语形上的矛盾形式还需要进一步被上升为语义上的真矛盾,但是真矛盾只对于承认(不)矛盾律的人来说才是问题,对于不承认矛盾律的人来说依旧不是问题。悖论之成为一个问题最终是因为矛盾可能导致不足道性。说谎者悖论作为悖论的一种,其成为一个问题也是如此。说谎者悖论与其他悖论的区别是构造矛盾形式的方式不同。说谎者悖论矛盾形式的构造需要特殊的句子、(T)模式以及相关的逻辑推理规则。由此出发,解决说谎者悖论的途径也可以从这三个方面来考虑:避免真的矛盾导致不足道性,限制矛盾形式成为真的矛盾,限制矛盾形式的产生。限制矛盾形式的产生又包括:限制特殊句子的产生,修改或限制(T)模式,修改相应的推理规则。
[Abstract]:Paradoxes are derived from the seemingly real premises through seemingly irrefutable reasoning to form a formula which is similar to P-Shao P or P-Shao P. This formula is only a form of contradiction in form. It is not a problem in itself. However, the real contradiction is only a problem for those who admit (not) the law of contradiction, but it is still not a problem for those who do not recognize the law of contradiction. Paradoxes become a problem because contradictions can lead to impotence. As a paradox, the liar paradox becomes a problem. The difference between a liar's paradox and other paradoxes is the way in which contradictions are constructed. The construction of paradoxical forms of liars requires special sentences, (T) patterns and relevant logical reasoning rules. Therefore, the way to solve the liar's paradox can also be considered from these three aspects: avoiding the lack of truth, restricting the form of contradiction into real contradiction and restricting the form of contradiction. Limiting the form of contradiction includes: limiting the generation of special sentences, modifying or restricting (T) mode, and modifying the corresponding rules of reasoning.
