“Chanting one’s emotions and dispositions” (吟咏情性) occupied the central position in the lyrical theoretical series of classical Chinese poetics. “Chanting one’s emotions and dispositions” had emotional and dispositional philosophy as its basic occurring condition. It marked the development from the views of “expressing one’s will” (言志) and “expressing one’s emotions” (抒情) in the general and collective poetics of the pre-Qin Dynasty to the lyrical theory of individualistic poetics. The literati poems of the Han-Wei Period were originated from the view of “expressing one’s will” and gave rise to the view of “expressing emotions” (缘情). During the Northern and Southern Dynasties, the poetic thought based on emotions and dispositions started to take hold. Besides “expressing one’s will” and “expressing one’s emotions,” the contemporary poets of that period often referred to their poetic writings in terms of “chanting their emotions and dispositions” . The Tang poetics accepted the view in the “Great Preface” (大序) about the “changed ballads and changed court hymns” (变风变雅) and the theory on emotions and dispositions of the Northern and Southern Dynasties. Its basic elaboration on poetic writings was chanting one’s emotions and dispositions and supplied the traditional theory on emotions and dispositions with such aesthetic notions as attaching importance to individuality and advocating naturalness. Although the Tang poetics upheld the didactic purpose of poem writing, its fundamental focus was still on those “changed ballads and changed court hymns” that chanted the poets’ emotions and dispositions. In the Song poetics, the theory on emotions and dispositions combined with the nature of individual ethics became the ideological foundation of the focus on “reason” (理) in the poems of the Song Dynasty. The poets of the Ming and Qing Dynasties still followed the traditional theory on emotions and dispositions and regarded emotions and dispositions as the basis of poem writing. Among them, there was the “School of Native Sensibility” (性灵派) whose view was to emphasize the natural expression of individuality and to value inspiration and innovation.
