耶林晚年的法律理论是一种古典的、人类历史的法律进化论模式 ,该模式出现在其思想成熟期的诸多著作中 ,但只有在该报告中 ,以耶林雄辩的口才才得以系统地展示。耶林首先提出了法权感渊源的二者择一的问题 ,即法权感是产生于历史呢 ?还是天赋的呢 ?耶林认为天赋论有三种形态 ,即天真的、进化的以及形式主义的 ,其区分标准为 ,道德真理对于人类是否天生就是完全的、萌芽的或纯粹形式化的。耶林驳斥的是自然赋予人类某种特殊装备的观点。他认为 ,人能够凭借自己的理解 (Verstand)出于自我保持的本能 (Selbsterhaltungstrieb)为自己的生存发现必要的道德与法律上的秩序。耶林主张 :随着时间的推移才慢慢产生了道德。法律就象一个漫游者 ,他在黎明接近日出时离家出游 ,历史是太阳 ,而法权感则是漫游者的影子。在日出前法权处于冷清状态 ,也没有影子 ,日出后或太阳照耀时 ,影子从法权后面 ,移到旁边 ,最后出现在法权的前面他从三个角度对这一论点进行了论证 ,即自然的角度、历史的角度与心理的角度 ,在心理方面他分析了法权在个体中产生以及一般化的问题。从第一个角度 ,耶林提出了一个人类学的问题 ,将天赋论陷于两难与矛盾之中 ,因为人类具有两个相互斗争的特性 :自私与无私。人类自私的自我保持本能控制着 The legal theory of Yelin in his later years is a classical legal evolutionary model of human history that appeared in many works during his mature period of thought. However, only Yelin’s eloquent eloquence can be systematically displayed in this report . Yelin first proposed the question of the duality of legal rights, that is, whether the sense of legal power came from history or from natural talent? According to Yelin’s theory, there are three forms of naturalism, namely naive, evolutionary and formalism , The standard of which is to distinguish whether moral truth is complete, sprouting or purely formal for human beings. Yelling dismissed the idea that nature gives humans something special. He believes that by virtue of his own understanding (Verstand) man can discover the necessary moral and legal order for his survival for his own self-sustaining instincts (Selbsterhaltungstrieb). Jelling claims: morality slowly develops over time. The law is like a rover, traveling away from home at dawn close to sunrise, history is the sun, and the sense of power is the rover’s shadow. The law of power was deserted before sunrise, and there was no shadow. After sunrise or the sun shone, the shadow moved from behind the law to the side and finally appeared before the law. From three angles, he made the argument Argumentation, that is, from a natural point of view, from a historical point of view and from a psychological point of view, psychologically, he analyzes the problems of the emergence and generalization of legal rights in individuals. From the first perspective, Yelin proposed a question of anthropology, which divested the theory of talent into dilemmas and contradictions because human beings have two characteristics that fight against each other: selfishness and selflessness. Human selfish self-preservation instincts control
