The ontological turn has brought to center stage the agency of nonhuman entities and has given validity of the knowledge held by non-Western collectives about such entities and about reality by and large. Furthermore, the ontological turn provides impetus to analyzing Western societies and modern practices through the concepts of indigenous, subaltern or excluded societies—an approach termed “reverse anthropology” by anthropologist Roy Wagner. Drawing on ethnographic research among the Andoque—one of the indigenous “People of the Center” of the Colombian Amazon—this article takes the thinking and ontological positions of Andoque members as its point of departure. The methodological approach taken in this article is different from common reflective approaches, which negate or limit the ability of researchers external to the studied group to produce knowledge on that group. Based on the ideal of alterity found at the core of Amerindian thought, it seeks a reverse movement, expressed by a radical autoethnography: to analyze the researcher as well as their culture through the concepts of the studied society. Focusing on the house of the dead, an esoteric yet central concept in the indigenous cosmology, this article seeks to account for the Andoque’s notion of power. By meticulously tracing the ways in which power is rooted in the living human body and in the indigenous territory, it further elucidates the indigenous notion of weakness, which, in times of colonial globality, is inextricably attached to the process that the Andoque term “becoming white.” Joining epistemological approaches that produce knowledge on globalization and modernity from the Global South, the approach taken in this article favors an indigenous Amazonian perspective, which gives priority to the categories of body and space over those of consciousness and time.
