The conceptualization of the notion of subjectivity within the Anthropocene finds in Rosi Braidotti’s posthumanism one of its most explicit and profuse modulations. This essay argues that Braidotti’s model powerfully accounts for the Anthropocene’s subjectivity by conceiving the “self” as a transversal multiplicity and its relationality to the “others” and the “world” as non-hierarchized by nature–culture distinctions; however, by being ontologically grounded on a neo-Spinozistic monism, Braidotti’s model blurs the notions of finitude, agency, and change, obscuring the possibility of critical (...) dissent while decreasing the overall theory’s consistency. An alternative ontological model capitalizing on these elements can be found in Object-Oriented Ontology and its notion of withdrawal. By associating OOO’s non-onto-taxonomical pluralism with Braidotti’s posthuman subjectivity, this essay aims at ontologically discretizing the latter in order to overcome these limitations. Grounded on this association and invoking a narrative imaginary propelled by the Greek terms xenos and xenia, the article paves the way for a form of subjectivity deviating from Braidotti’s ecological model and defined as xenological, arguing that, within the context of the Anthropocene, it constitutes an adequate alternative to Braidotti’s subjectivity.
