In this introduction, we propose a new approach to anthropological knowledge making that would observe the ‘hyper-reflexive’ quality of ethnographic exchanges. We show that anthropological ideas infiltrate themselves into the discourse of native thinkers, even as native ideas regenerate anthropological theory. Our starting point is ‘animism’, a key concept of anthropological theory. We suggest that anthropologists and their interlocutors jointly reinvent animistic ideas through a process we describe as the ‘reflexive feedback loop’, in which abstract ideas about practice and belief are appropriated and recirculated by research participants. By way of conclusion, we reflect on how anthropologists and their collaborators ‘animate’ soul concepts through diverse forms of agency such as metamorphosis, doubling, autobiographical narrative, hidden jokes, and even technological animism.
