在中国文学史上 ,宋诗之所以确立与唐诗并峙的地位 ,最重要的原因在于其构建了重“理”特质。考察以重理为核心的宋诗本质特征的形成过程 ,即清晰地表现出与作为宋学核心体现的理学之间的深刻的内在关联。南宋后期 ,宋诗的重理特征发生变异 ,诗坛出现向唐诗重情范型总体回归的倾向 ,“宋调”至此而趋向式微。理学事功派学者本身多为文士 ,他们以反对深受理学影响的江西诗派为契机 ,倡言晚唐风韵 ,在实践上推进了“宋调”式微的创作进程 ;理学正统派在“心”与“理”的对立中使“情”得以高扬 ,从而在观念上促进了“宋调”式微的理论进程。由理学分化与“宋调”式微的各自进程 ,可以见出中国思想史与文学史实际上存在着的一体化关系 In the history of Chinese literature, the most important reason why the Song poetry established its position as the Tang poetry is that it constructs the heavy “reason” qualities. The formation process of the essential characteristics of Song poetry with the core of the theory of remembrance at its core is the clear intrinsic connection with the Neo-Confucianism which is the core of Song studies. In the late Southern Song Dynasty, the general characteristics of the Song poetry were changed. The poetry tended to return to the general paradigm of the Tang poetry. The “Song tune” tended to decline. Neo-Confucianism scholars themselves are mostly scholars. They oppose the Jiangxi Poets School influenced by Neo-Confucianism as an opportunity to advocate the charm of the late Tang Dynasty and promote the process of creation of “Song tone” in practice. Neo-Confucian orthodoxy, In the opposite of “reason”, “love” was promoted, which promoted the theoretical process of “Song tune” in concept. From the respective differentiation of Neo-Confucianism and Song-style, we can see that there is actually an integrated relationship between Chinese intellectual history and literary history
