Nowadays, research ethics review is completely conducted within Ministry of Science and Technology in Taiwan, which inspires the researchers to reflect on ethical issues of narrative research. First, in this study we review the code and requirement of existing research ethics and realize that the principle of research ethics review is derived from the source of biomedical research, which is based on the concept of Dualism and the social contract. Second, we review Kant’s Modernism and a Theory of Jutice, then turning postmodern hermeneutics of narrative and the concept of Interactionism. Inter-subjectivity is the core concept of ethics. In summary, this paper finds that narrative research is different from I-It relation, the ethical relation of researchers/the manipulated and interviewees from biomedical research, but it is I-Thou relationship from the ethical core of inter-subjectivity, assuming the goal of interaction and inter-understanding.
