法律与道德“结合命题”何以可能？--兼评富勒的“内在道德”学说

朗·富勒清楚地认识到，他与法律实证主义者之间存在严重的分歧。根本的原因在于各自的法律观不同，而两种不同法律观的核心争议点在于法律与道德关系问题上的分歧。由此展开的争论，可归结为“分离命题”与“结合命题”之争，其核心在于是否承认法律与道德之间的逻辑“必然性”。富勒对此做过一套逻辑上的论证，其“内在道德”学说旨在克服“分离命题”；只不过他所借助的概念分析和模态逻辑，也是伦理自然主义者所借助的重要理论工具。这种研究，对于我们进一步理解法律和法治有重要意义。

How Is Connection Thesis of Law and Morality Possible？---Towards the Law of Internal Morality

Lon L.Fuller has clearly recognized the fact that different conceptions of law bring about his disagreement with legal positivists, their diverse views on the relationship between law and morality being the focus.It can be concluded that the controversy between them can be viewed as“the separation thesis” vs.“the connection thesis”, and the core is whether to recognize the logic“necessity” between the law and the morality.In fact, Fuller has provided a logical argument for this connection thesis.The law of internal morality, proposed by Fuller, attempts to overcome the weakness of the separation thesis by means of modal logic and formal logic, which is also an important theoretical tool for ethical Naturalists.Therefore, it is of vital importance for us to understand the law and judiciary.
