Taking as a starting point a research experience in collaboration with two Mapuche interlocutors, this article explores learning derived from the proposal they were making to us: basically, embarking on the intersubjective, interepistemic and interexistential production of knowledge. Intersubjective, because the goal had to be to transform/complete our understandings and selves in and through the interaction. Interepistemic, to the extent that it had to open ourselves to recognize not so much other knowledge but other ways of knowing. Interexistential, since it would expose us to the opacity of certain ontological borders according to which the practice of conversation can, in its being done, involve --at least for some-- living human persons and non-human beings. On this basis, we aim to intervene in broader debates about certain mandates and extended conceptions of contemporary anthropological work. [ABSTRACT FROM AUTHOR]
