法律推理是法律适用的主体。在描述性与规范性的双重视角下,可将其刻画为:通过论证(论辩)获得推理的前提——规范与事实,并最终从前提到结果的推导过程。基于此,法律推理的理论模型可建立在两个基点之上:一是“推理核”;二是“论辩层”。“推理核”关心法律推理的起点和基本形式结构;“论辩层”则拓展了论辩对话的具体方法、程序性规则和评价标准。至此,可对法律推理展开分析和重构。 Legal reasoning is the main body of the law. In the descriptive and normative dual perspective, it can be portrayed as: by argumentation (argument) access to the premise of reasoning - norms and facts, and ultimately the derivation of the results from the previous reference. Based on this, the theoretical model of legal reasoning can be based on two basic points: one is “reasoning nuclear ”; the other is “argument layer ”. “Reasoning nuclear ” concerned about the starting point and the basic form of legal reasoning structure; “debate layer ” expand the specific methods of argument, procedural rules and evaluation criteria. At this point, the legal reasoning can be analyzed and reconstructed.
