法理学与部门法学的三重关系
雷 磊*
摘 要：今日之部门法学的典范乃法教义学。法教义学的兴起是中国法学摆脱幼稚之讥、走向专业化的必由之路，但这绝非意味着它的封闭和隔阂。法学成熟的一个重要面向在于法理学与部门法学真正融为一体。法理学与部门法学的关系至少体现在三个方面：其一，抽象与反哺，即由特定部门法学供给理论原型、由法理学进行抽象并反哺于各部门法学，即包括法律概念的一般化与反哺，也包括法学方法的体系化与反哺；其二，输入与运用，即由法理学输入法学外的其他学科的观点或方法，进而运用于部门法学，主要体现为（狭义的）哲学理论的输入与运用，以及伦理学理论的输入与运用；其三，蕴含或融合，也即法理学说本身蕴含部门法理论，或者与部门法理论相融合。法理学并不会形成相对于部门法学的“知识冗余”。可以说，没有部门法学的法理学是空洞的，而没有法理学的部门法学是盲目的。

Three Models of Relationship between Jurisprudence and Department Laws
Lei Lei
Abstract: The paradigm of department laws research nowadays is legal dogmatics. The rise of legal dogmatics symbolized a way for Chinese legal science to get rid of the "immatureness-ridicule" and start a process of professionalization, which by no way means its own closeness and insulation from department laws. An important aspect of a mature legal science lies in the real mixture of jurisprudence and department laws. The relationship between jurisprudence and department laws demonstrates in three ways: firstly, abstraction and feeding-back, i.e., certain department law provides a theoretical prototype and then jurisprudence gives an abstraction in oder to feed back to various department laws. This model includes not only generalization of legal concepts and feeding-back, but also systematization of legal methods and feeding-back. Secondly, import and application, i.e., jurisprudence imports viewpoints or methods from sciences other than legal science, then applies them to department laws, which mainly manifests both as import and application of philosophical theories (in narrow sense), and that of ethical theories. Thirdly, implication and unification, i.e., doctrines in jurisprudence implicates certain theories in department law itself, or unifies certain theories in department law as a whole. Therefore, jurisprudence does not constitute “redundancy in knowledge” comparative to department laws. In a word, jurisprudence without department laws is empty, and department laws without jurisprudence are blind.
