中唐文学新变与 “感人心” 的政治观念密切相关。 盛唐文学与唐人欲透过制礼作乐构建太平盛世的观念密切联系，是故文章从属于礼乐，文士则以润色鸿业 颂美盛世为志。 安史战后，盛世不再，中唐面临秩序重建的迫切问题，转以《易传》“圣人感人心而天下和平” 为观念基础，力图通过建立人心认同来重建王朝秩序。 中唐文章变革实建立在此一新的观念基础上，故改良现实的时政褒贬之文取代盛唐的礼乐雅颂之文，目的正在于透过感人心以致和平，再造盛世。

The new changes of literature in the Mid-Tang Dynasty were closely related to the political idea of “touching the human mind”. The literature in the heyday of the Tang Dynasty was closely associated with the idea of the people at that time, who intended to achieve peace and prosperity through setting up new rites and making new music. Therefore, literature became subordinated to ritual and music, and the literati took it as their ambition to embellish and eulogize the great age. After the rebellion led by An Lushan (安祿山) and Shi Siming (史思明), the heyday of the Tang Dynasty came to an end and the Mid-Tang people were faced with an urgent need of reconstructing the socio-political order. They turned to the idea from Yi Zhuan (《易传》), which emphasized that if the sages touched the human mind, the world would be in peace. This idea then became the new ideological basis for the Mid-Tang people to strive for the re-establishment of the dynastic order by building the recognition of their mind identity. As the new changes of the Mid-Tang literature were actually grounded upon this new ideological basis, the eulogistic literature from the heyday of the Tang Dynasty was replaced by the new literature focusing on praising and criticizing current politics so as to reform reality. The new literature was aimed to bring about peace and reconstruct a prosperous world through touching the human mind.
