This contribution looks at a specific case of academic discourse, that of the positioning of various scientific discourses within social and media spheres. More specifically, it examines how concepts used in the Social and Human Sciences (SHS) are discursively constructed by members of different scientific fields. The approach is thus “cross-cultural” in the sense that the contribution is analyzing discourses stemming from different (sub-)disciplinary cultures. It considers the case of the (co-)construction of scientific concepts within the specific context of a radio broadcast involving a philosopher (the interviewer) and a sociologist (the interviewee). During the discussion, several concepts are introduced by the interlocutors (“understand vs. explain”, “recognition”, “the subject”, “ethics”, “norms”…), which are defined, redefined, exemplified, etc. The paper scrutinizes some discursive phenomena through how the philosopher and the sociologist build upon, (co-) construct and reformulate each other’s definitions and ideas, as well as their own. This is complemented by an analysis of the various positions taken by the interlocutors as well as their interaction strategies in creating their lines of thought. The ultimate goal of the article is to attempt a description of a type of academic discourse which is understudied.
