“诗言志”说和“诗缘情”说是上古诗论的两组重要概念,前人有很多深入的研究。这两组概念最主要的区别是其理论角度的转换,即从文学的功能叙述转换为文学的本源叙述。在先秦两汉的文献中也能发现这一转换渐次发生的证据。 “Poetry Express” and “Poetry Emotion” are two important concepts in ancient poetry theory. There are many in-depth studies of predecessors. The most important difference between these two groups of concepts is the conversion of their theoretical perspective, that is, from the functional narrative of literature to the original narrative of literature. In the literature of the pre-Qin and Han dynasties, evidence of this gradual transformation can also be found.
