Abstract:From the theory of childlike innocence to the theory of spirit profound changes have taken place in the stipulation of the subjectivity of literati. Li Zhi 's three-element theory of talent ,courage and knowledge attaches great importance to the independent perception and critical ability of the writing subject. Yuan Zhongdao 's theory ,based on Li Zhi 's theory of the three elements combines theory of interest Yuan Hongdao put forward in the 25th year of Wanli with the tendency to emphasize learning after the 27th year of Wanli, and by integrating the five elements of the spiritual subjects, that is ,knowledge, talent, learning, courage and interest, it forms a new discussion characterized by advocating interest and emphasizing learning. Advocating interest derives from Yuan Hongdao 's life experience with the natural landscape when he wandered Wu-Yue, and emphasizing learning is his poetic experience generated from the collection of Song people and the practice of Zen when he worked in Beijing. Unifying the tendency of advocating interest and emphasizing learning to endow the spiritual subject with a new meaning is the School of Gong-an?s important development of the theory of spirit poetics, showing the evolution of poetics in this period.
