Who is the poetry theorist who puts forward that reason is the three elements of poetry?

Ye Xie put forward that "if my talent, courage, knowledge and strength can be reflected in the reason, matter and emotion of things, then the law of nature will be established and the power of poetry will be finished". Therefore, regarding meter, tone, ups and downs, care and so on, he inherited Lv Benzhong's theory of "living method", took "death method" as the "nominal name", and asked the gods to change so as to meet the needs of reflecting reason, things and feelings. Of the three "reasons, things and feelings", Ye Xie emphasized "reason" and thought that "the reason and Tao are the body, and things and feelings always run through them", so "only knowing the reason can be written out". Of the four "talents, courage, knowledge and strength", Ye Xie emphasized "knowledge", holding that "knowledge is the body, but talent is used", and "knowledge is bold". Without "knowledge", talent, courage and strength will be rebellious and become an elegant sinner. He also claimed that "reason, matter and emotion" are "the third in things", but "those who prepare things are greater than heaven and earth, and heaven and earth are prepared in the Six Classics; The six classics have the power of reason, matter and emotion, so it is necessary to be "suitable for Tao" to reflect "reason, matter and emotion" This theory, which reflects "reason, matter and emotion" with "talent, courage, knowledge and strength", is Ye Xie's main creation in literary theory, and he has made it the purpose of "The Original Poetry" and his own literary theory several times.
