Abstract: Professor Yang Huilin expounds his views on the problem domain and methodology of comparative literature studies by answering questions on the topics of interdisciplinary research based on his research experience of the comparison of theology and humanities, scriptural reasoning, etc. Yang believes that comparative literature needs to find productive and instrumental concepts instead of only adopting descriptive ones. In this respect, the study of Ereignis by Western scholars such as Heidegger may bring us useful inspiration. Yang also believes that the discipline construction of comparative literature does not have to rush to establish the“Chinese school,” and that comparative literature is more like a problem domain. More importantly, it is necessary to stimulate unique problem awareness and research methods through comparative research.
