In this article, I explore the ontological turn in anthropological theory through three interconnected approaches. First, I situate the academic success of Amerindian ontologies in the context of recent debates on the urgency of addressing the political consequences of the anthropocene. Secondly, I undertake an archaeology of the concept of perspectivism as a central stage of the ontological turn, showing how the sub-discipline of Amerindian ethnology has always had a vocation for Copernican turnings, from the time of Montaigne until today. In conclusion, I argue for a return to aesthetics and poetics as the quintessential domains for exploring how different ontologies can teach us to look at the world differently. To understand the multiple versions of Amerindian relational ontologies we have to be able to perceive the relational character of the aesthetics they reveal. The argument is sustained by a short presentation of Huni Kuin (Cashinahua) aesthetics as revealed in huni meka, ayahuasca song.
