Literary studies as a subfield of the humanities since the modern period has been categorized into the productive mode of discipline-systemizing,involving the relevant issues of knowledge attribute,function and discipline structure as well as interdisciplinary approaches.Literary writing and literary studies not only provide people with an entrance to the exploration of possible worlds and present different cognitive functions,but also make up for the scope of deterministic knowledge as well.Literature,as a specialized knowledge within a discipline,has been related to national language,transformation of cultural tradition,advancement of modern education and the development of literary studies itself.The advantage of discipline-based approach will bring about an in-depth and systematic development of all the specialized knowledge while making the transfer of the given knowledge more specialized in higher education.It is true that all kinds of expertise are improved in such a disciplinary-systemizing process;however,to a large extent,the artificial boundaries between subfields formed by disciplines would be solidified,which would not be conducive to the crossover,transfer and reference of relevant knowledge between disciplines.This is especially true for the effective study of literary texts with vivid imagery and linguistic encoding,whose specific forms and nature of knowledge have led directly to the historic emergence of interdisciplinary approaches.In view of the long-term expansion of literary studies in a discipline-based way,the issues of knowledge,discipline and interdisciplinarity in this subfield have become definitely unavoidable.As both literary writing and literary studies connote the complicated cultural and knowledge factors integrated within history,they are not the result of intentional activities of the individual only,because the former remains in relation with writing signs,cultural tradition,perception and certain aesthetic quality in historical periods while the latter,however,covers the factors of textual milieu,research resources,mode of communication and cross-cultural experience beside the aesthetic analyses of the textual encoding.Therefore,the advancement of literary studies is always accompanied by the intersection and convergence of various elements such as language,history,culture,society,and concepts,which objectively requires the continuous deepening of interdisciplinary methodology.Grasping the intellectual characteristics and interdisciplinary methods of literary studies will make the academic rationality of this subfield more prominent,and at the same time,it will also inspire researchers to constantly break the disciplinary framework,pay attention to the intellectual resources of different language features,cultural traditions and different disciplines,and produce a real sense of knowledge integration at the intersection of cultures.Rethinking the basic issues of knowledge,discipline,and interdisciplinarity in literary studies will not only be conducive to highlighting the intellectual orientation of this field,but also help people break the inherent boundaries and see through the multiple integration characteristics of knowledge-oriented and cognitive types contained in it,so as to provide the insights for Chinese scholars today under the premise of knowledge sharing.
