This essay explores a concept of 'we' that without rejecting the grammatical use of enunciation focuses on pragmatic that underlies it, from which his community and exclusivity conditions confront with his fundamental ontological otherness. In light of poststructural anthropology thesis of the Brazilian ethnologist Eduardo Viveiros de Castro, discuss, on one hand, the necessity to enunciate the 'we' in his capacity of radical differentiator and, on the other, the inability to establish it substantially since refers inexorably to otherness. In the first part, it exposed that the nontrivial sociocultural theories of anthropology are a co-production between the anthropologist and the studied community. On second instance, it present the way in which the 'we' gives rise to an irreducible difference not only previous to the Self, but essential and affirmative. Third, it arise an immanent community characterized by an underlying multiplicity of any organizational enunciation of 'us' and composed by the machinic alterity. In conclusion, this paper affirms the 'we' in its becoming inasmuch as an-other-to-come, which functions as an existential political act.
