法律解释中的数学思维

Mathematical Thinking in Legal Interpretation

法律与数学存在相似之处。裁判者是否能援用数学证明的方法,在疑难案件中发现或设定一条辅助定理,可旁证法律解释最终能否获得"真的"或普适意义上的客观性。通过个案分析表明,数学证明中的病例排除法、例外排除法、辅助定理整合法对评判裁判者的解释是有启发的。但由于数学命题与规范命题的差异,以及法律解释自身的特殊性,数学思维在解释中的"运用",终究只是一个表象、一种修辞。

There are similarities between law and mathematics. By citing a mathematical testifying method, the judges can find or establish an auxiliary theorem so as to testify whether legal interpretation can have ultimately the ＂real＂ or general objectivity. By analyzing the particular case, mathematical testifying methods such as method of case exclusion, method of exception exclusion and integrating method of auxiliary theorem contribute to the interpretation of judges. But due to the differences between mathematical proposition and standard proposition and the particularity of legal interpretation, mathematical thinking is just an idea or a kind of rhetoric in the application.
