试析司法论证的逻辑学进路

Logic Approaches to Judicial Argument

基于不同的法理学观就有不同的法律逻辑观。在形式主义法理观下,司法论证具有多元的单调逻辑系统。在实用主义法理观下,司法论证的逻辑基础是非单调基础逻辑和非单调应用逻辑。因此,单调逻辑是司法论证的必要基础,尽管不够用,非单调逻辑是对单调逻辑的补充,而不是对单调逻辑的否定,司法论证的任务在于把握非单调推理和单调推理在实际司法推理中的作用机理。"非单调应用逻辑"可以作为评价司法论证实质向度和程序向度的推理有效性工具。这一研究领域正成为法律逻辑新的增长点。

In view of legal pragmatism,logical basis of Judicial Argument is non-monotonic logic.Therefore,the monotonic logic is a necessary foundation for the judicial argument,though not enough,non-monotonic logic is monotonic logic of the supplement,rather than the monotonic logic of negation,monotonic reasoning and non-monotonic reasoning have the joint work in the actual judicial reasoning.＂Non-monotony of applied logic＂ can be used tools of reasoning effectiveness as evaluating the real dimension and procedural dimension.The field of research is becoming a new growth point of legal logic.
