富勒的内在道德论确立了自然法中的程序自然法。通过与哈特的论战,富勒提出了的法的内在道德与外在道德这一划分,使分析实证主义主导下的法律世界重新审视自然法。在《法律的道德性》一书中富勒向我们描绘和展现了法律的内在道德这一愿望品质,同时指出“法律是使人类行为服从规则之治的事业”。本文就通过对富勒法的内在道德论的研究来分析我国法制的发展历程。 Fuller’s internal moral theory established the natural law of procedure in natural law. Through the polemics with Hart, Fuller proposed the division of internal morality and external morality of law, so that the legal world under the guidance of analytical positivism reexamined natural law. In the book Ethics of Law, Fuller portrayed and demonstrated to us the quality of aspiration of the inner law of law and pointed out that “law is the cause of obeying human behavior under the rule of law.” This article analyzes the development of our country’s legal system by studying the internal moral theory of Fuller’s law.
