魏明帝现存诏书中的正统观念,主要涉及应天受命、符瑞灾异、天下一统、中原正统、改正朔以及通三统等几个方面。魏明帝诏书中所体现的正统观念,主要是对先秦、秦汉正统观念尤其是对汉代春秋公羊学正统观的继承与实践,其理论基础是“天人感应”宇宙论和儒家礼乐文化,其历史依据是儒家所认定的三代至秦汉的政治传统。通过对前人正统观念的继承与实践,魏明帝为曹魏代汉自立寻得了合法性依据,也为自身在三国鼎立政治格局中谋求正统地位提供了合法性依据,具有重大的现实政治寓意。 The orthodox concepts in the existing imperial edict of Wei Mingdi mainly relate to several aspects, such as the command of heaven, the ruin of disasters, the unification of the world, the orthodoxy of the Central Plains, the revision of the new moon and the introduction of the three systems. The orthodox ideas embodied in the imperial edict of Wei Mingdi are mainly the inheritance and practice of orthodox ideas of the Pre-Qin and Qin and Han Dynasties, especially of the Spring and Autumn Rams in the Han Dynasty. The theoretical basis is “cosmic theory of heaven and man” and Confucian rituals Its history is based on the political traditions of the three generations of Confucianism and the Qin and Han Dynasties. Through the inheritance and practice of the predecessors’ concept of orthodoxy, Wei Mingdi found the legitimacy basis for the independence of Cao Wei on behalf of the Han Dynasty and also provided the legitimacy basis for seeking orthodox status in the tripartite political structure of the Three Kingdoms with great realistic political implication.
