Legal Reflection Of Normative Logic

Normative logic (also called deontic logic), which is about the logic ofobligation, permission and such norm modality, is a branch of broad modal logic. Theresearch on normative logic in China is not for a long time. Only recently somescholars begin to study it. Comparing with western countries, our study in this fieldlag behind. One of the reasons lies in normative logic itself, such as in its paradox orin its inconvincible system. Another reason lies in the fact that less attention has been paid to it. In fact, thestudy of normative logic is very important no matter in the view of logic itself or inthe view of the science of law. Normative logic takes law as its object language tostudy, while takes formal language as metalanguage to study the essential concept oflaw and legal norms and their inner relationship, so as to make the law an innerconsistent system and remove the contradiction. It becomes a new, analyzing tool forthe study of law. The article just tries hard to analyse the importance of normative logic to thestudy of law. The article is organized into five parts: The first part is a brief introduction to the development of normative logic. The second part is a summary of Von Wright's one-place normativepropositional logic and analysis of some theorem of it from the science of law. The third is a summary of the standard one-place normative propositional logicand analysis of some theorem of it from the science of law. The fourth is a summary of Anderson's normative propositional logic andanalysis of some theorem of it from the science of law. The last part is analysis of dyadic normative propositional logic from the scienceof law.
