“命题”是刘勰《文心雕龙·附会》篇用来表述其结构理论的主要方式,这些命题的构成形式有单句式、双句式和多句式三种类型。《附会》篇命题的理论内涵主要涉及到结构功能论和结构审美论两方面。由于《附会》篇命题体现了古今文学创作的结构原则和规律,因而这些命题不但对后世的结构理论产生了深远影响,而且在当代仍然具有切实的应用价值。 “Proposition ” is the main method used by Liu Xie’s “Wen Xin Diao Long Xi Fu Hui” to describe its structural theory. The forms of these propositions are single sentence type, double sentence type and multiple sentence type. The theoretical connotation of the proposition of “Fu Hui” mainly involves two aspects: structural function theory and structural aesthetic theory. Since the propositions of “Fu Hui” embody the structural principles and laws of ancient and modern literary creation, these propositions not only have a profound impact on the structural theory of later generations, but also have practical value in the contemporary era.
