Research is our radical search-around in all directions imaginable. It inevitably turns to self-scrutinize to self-direct toward comprehensive interculture, as interaction of many modes of thinking and searching, even methodologically on how research goes. This Socratic-comprehensive turn of research is philosophy, research of all researches. This essay common-sensibly elucidates their triune intimacy, from research via philosophy to interculture. Thus this essay has three parts, A: research, B: philosophy, and C: interculture. Part A researches into why, what, and how of research, and then explores its Janus-faced door. Part B reflects on what was explained on research as philosophy, as catalyst of research to interculture. Part C, 1) looks at two contrastive cultures, the West and China as typical of “many world cultures,” 2) how the West and China interculture, to conclude with two cautions on interculture in our research.
