从1934年翻译玛尔霍兹的《文艺史学与文艺科学》开始，李长之有意逐步将“文艺科学”的体系移植到中国，通过这一文教体制的构建工作，以实现他对于现代文学理论形态的设想。本文以分析李长之的“文艺科学”的构想为切入口，梳理“文艺科学”在本土化的构型过程当中所借鉴的德国资源，考察与精神科学的承接关系，并进一步分析如何影响了李长之的文学批评理念和批评实践，探寻为何成为未竟之事业，试图再解读草创期中国文学理论现代构型的危机与困惑。 第一节梳理李长之“文艺科学”知识谱系当中的研究对象与研究体系的问题，首先厘清“文艺科学”研究体系下“文学”的概念，其次分析“文艺科学”的整体架构，梳理“文艺科学”的组成部分和各部分的研究任务。 第二节重点是探讨李长之批评理念的核心：“感情的型”，分析李长之的文论，并梳理“感情的型”的具体内涵。从李长之的文学活动来观测他是如何实践了“感情的型”的批评理念，主要是解读30年代描摹鲁迅、司马迁、屈原等人浪漫品性的作品，分析背后所蕴含的人文理想。 第三节以“理性的硬性”为出发点，探讨在抗战时期李长之在个人本位与国族想象之间的矛盾纠葛，一是继续分析他的传记批评当中的人格理想产生了怎样的变化，二是仔细辨析其文论当中的“体验”概念，探究为何文艺科学成为未竟之事业的原因。 以李长之的“文艺科学”构想为出发点，分析文本并挖掘知识内部的逻辑，返回到李长之文学理论构想之初的多维立意，将为学科建制的反思提供一些珍贵的回忆。
