一门独立学科的研究对象是独立于其他学科的。一般说来,不属于该学科的研究对象该学科绝对不可涉猎。反之,如果用该学科的研究方法和规律去研究其他学科的对象,则往往容易把问题的研究引入误区。特别是交叉学科,如果在未真正确立自己的研究对象之前就匆匆构建自己的研究方法和规律,这样更易产生许多棘手的问题。“典型”理论的研究正是这样坠入误区,而又在寻找出路时陷进困境的。文艺美学作为文艺理论和美学的交叉学科,是应该明确地拥有自己的独立研究对象的。但是,由于历史的关系,文艺理论和美学均脱胎于哲学,这使得文艺美学和美学一直难分难舍, The subject of an independent discipline is independent of other disciplines. In general, the subject does not belong to the discipline of the subject must not be underestimated. On the contrary, if we use the disciplinary research methods and laws to study the subjects of other disciplines, it is often easy to introduce the research into the errors. In particular, interdisciplinary subjects pose a number of thorny problems if they are to construct their own research methods and laws in a hurry before they really establish their own subjects. It is just such a study of “typical” theory that has fallen into misunderstandings and is stuck in a dilemma in finding a way out. As an interdisciplinary subject of literary theory and aesthetics, literary aesthetics should have its own independent research object explicitly. However, due to the historical relationship, literary theory and aesthetics are born out of philosophy, which makes literature and art aesthetics and aesthetics have been difficult to distinguish,
