易堂九子是明末清初重要的士人群体。他们的文法理论构成其文学思想的重要组成部分。与唐宋派和桐城派相比,易堂九子的文法理论具有形而上色彩,这与明末清初的历史语境密切相关。他们主张由规矩到神明,既是易代之际立言的法则,又针对有明一代的模拟文风,具有现实意义。 Yi Tong nine children is an important group of scholars in Ming and early Qing. Their grammar theory constitutes an important part of their literary ideas. Compared with Tang and Song dynasties and Tongcheng factions, Yi Tong’s Nine-gram theory has a metaphysical sense, which is closely related to the historical context of the late Ming and early Qing dynasties. They advocate that the rule from the god to the god is not only the principle of making speech while giving speech in the days of generation, but also the realistic writing of the style of writing of the Ming generation.
