系统科学的方法和比较文学的方法都是文学研究的重要工具,并且已经取得了巨大的成果。同时,二者之间又存在着很大的联系。但是,系统科学在引入到文学研究领域的时候并没有深入地发掘这种联系,更多的时候,文学研究者的眼光是以一种拿来的姿态来运用传统的以“三论”为概括的系统论的,从深层上来看,这也体现了人文科学与自然科学的学科分野问题。文章主要就比较文学的跨学科性进行了分析。 Systematic and comparative literature methods are both important tools of literary research and have yielded tremendous results. At the same time, there is a great connection between the two. However, systematic science did not explore this connection in depth when it was introduced to the field of literary studies. More often, literary researchers’ perspectives were based on the traditional approach of “three theories” System theory, from the deep point of view, it also reflects the humanities and natural sciences disciplinary issues. The article mainly analyzes the interdisciplinarity of comparative literature.
