法律规范性是当代分析法哲学中的难题。作为法律实践的参与者,我们都认为法律对我们的行为施加了约束,但法律是立法者意志的产物,其存在仅是事实问题,这就意味着法律的内容可能是任意的。那么我们作为理性自主的个体,法律存在这一事实是以何种方式约束我们的行为?其施加约束的依据是什么?在法律实践中,理性主体的自主行动和法律的要求之间隐含着内在的紧张,法律的规范性问题也成为法律理论最大的困难。法律规范性理论包括概念和来源两个不同的问题。〔1〕概 Legal normativity is a difficult problem in contemporary analytical philosophy. As participants in legal practice, we all think that the law imposes restrictions on our behavior. But the law is the product of the legislator's will. Its existence is only a matter of fact, which means that the content of the law may be arbitrary. So, as an individual with rational autonomy, what is the fact that the existence of the law restricts our behavior? What is the basis for its imposition of restraint? In legal practice, the discrepancy between the autonomous actions of the rational subject and the legal requirements implies Internal tension, normative issues of law has also become the biggest difficulty of legal theory. Legal normative theory includes concepts and sources of two different issues. 〔1〕 General
