本文通过对佩策尼克《法律科学——作为法律知识和法律渊源的法律学说》的理解,展示了晚年佩策尼克的学术观点。针对法律学说随着社会的发展受到的不断挑战与批判,他提出法律学说的“哥白尼转向”。通过对实证主义法学派和自然法学派对道德和法律关系的批判,佩策尼克提出了一个在融贯论要求下的摒弃本体论的认识论,他的这种通过弱式理论对法律学说进行理性重构的尝试向我们展现了一个学者不懈努力的精神。 In this paper, through the understanding of Peznikov’s “Legal science - the legal doctrine as the source of legal knowledge and law”, it shows Pertenick’s academic viewpoint in his later years. In response to the constant challenge and criticism of legal doctrine with the development of society, he proposed the “Copernican Turn” of legal doctrine. By criticizing the moral and legal relations between the schools of positivist jurisprudence and the schools of natural law, Petznik proposed an epistemology of abandoning ontology under the requirement of cohesion theory. His theory of rational weight through legal theory of weakness The attempt to construct shows us the spirit of a scholar’s tireless efforts.
