《毛诗序》有相对一致的解释思路,十五国《风》、大小《雅》各部分的《序》表现出一定的系统性,相邻的《序》文也往往有一定的关联度,则其很可能成型于一人之手。三家《诗》本无序、四家《诗》解说有不少歧异,说明《毛诗序》非出于诗人、国史、周之乐官、孔子、子夏。先秦时期虽也有以政治教化、伦理道德解《诗》的趋向,但尚未成为普遍原则。《毛诗序》与三家《诗》皆以政治教化、伦理道德解《诗》,说明它们是同一时代的选择。而《毛诗序》比三家《诗》有更浓厚的政治教化的意味,则《毛诗序》晚于三家《诗》的创立。三家《诗》的创立在高后至文帝时,结合《序》《传》关系、《序》的资料来源,可以断定《毛诗序》的成型在景帝前元二年至中元五年间。 There are relatively consistent explanations for the “Mao Poetry Preface”. The “Prefaces” of the “Winds” and the “Graceful” parts of the 15 countries show a certain degree of systematicness. The adjacent “Prefaces” texts also tend to have some degree of relevance , It is likely to be shaped by one person. There are quite a few differences between the three “poems” and the explanation of the four “poems”, which shows that Mao’s Preface is not based on the poets, the national history, the officials of the Zhou Dynasty, Confucius, and Zi Xia. Although pre-Qin period also had the tendency to solve “poem” by politics and ethics, it has not yet become a universal principle. Maoist Preface and Three Poems are both political enlightenment and ethical moral solution poem, indicating that they are the same time choice. The “Mao Poetry Preface” than the three “Poems” have a stronger political enlightenment, then the “Mao Poetry Preface” later than the creation of three “poems.” When the three “poem” was founded from the high to the emperor, combining the sources of “preface”, “preaching” and “Preface”, we can conclude that the formation of “Mao Poetry Preface” was between the second year of Emperor Jingdi and the fifth year of Yuan Dynasty.
