认知语言学中的原型范畴理论是一个结构化的、多产的、解释力很强的辩证性认知理论。文学中的原型是一个无所不包的、永恒的、形式多样的抽象概念。本文通过对比分析两者的定义、发展和性质,发现虽然原型范畴理论的内涵意义不像文学中的原型意义丰富,但是两者的理论基础和认知机制却相同。并且,原型范畴理论不仅在理论层面可以扩展原型的研究范围,在认知层面揭示原型意义的生成过程,还可以在文化层面上分析原型是世界文学宝库中不可或缺的瑰宝的原因。 Prototype theory in cognitive linguistics is a structured, prolific and highly explanatory dialectical cognitive theory. Prototypes in literature are an all-encompassing, eternal, abstract concept of diverse forms. By comparing and analyzing the definition, development and nature of the two, we find that though the connotative meaning of the prototype category theory is not as rich as the prototype meaning in literature, the theoretical basis and cognitive mechanism of the two are the same. Moreover, the theory of prototype category not only expands the scope of prototype research in theory, but also reveals the generation process of prototype meaning at the cognitive level and also analyzes the reasons why the prototype is an indispensable gem in the world literature database at the cultural level.
