Long Abstract: In this paper I reflect on the scope and challenges of practicing an anthropology inspired by the ontological turn for the study of realities in which, we suspect, processes of (post)colonial domination take place. I propose a dialogue between traditions concerned with unveiling asymmetrical power relations (Mintz, 1996; Wolf, 2000; Grosfoguel and Mignolo, 2008) and the ontological turn's bid to take seriously the explanations of the people we study about the worlds they live in (Viveiros de Castro, 2004; Willerslev, 2007; Holbraad, 2008; Pedersen, 2011; Kohn, 2013; González Varela, 2015; Wagner, 2016,). My intention is to make both approaches beyond the traditional etic-emic reading, where the analysis of "the structural" constitutes the "objective" moment and the informants' accounts are the "subjective" moment (Bourdieu, 2005). This opposition in the social sciences has traditionally led to not taking informants' explanations seriously, under the assumption that their narratives are traversed by relations of domination that they do not perceive. From an ethnographic study that I advanced between 2018 and 2020 on the coloniality of the consumption of European cultural products in Mexico City, Rio de Janeiro, São Paulo and Bogotá, I test the possibility of practicing this double approach to reality through the visibilization of irreducible worlds in which, nevertheless, it is possible to identify ontological intersections.
