A non-Christian mathematics. Unstable sets in Indigenous Amazonia

In the Amazonian literature, the scarcity of numerical terms and lack of interest in counting, which characterize diverse indigenous groups in the region, are usually associated with linguistic issues or cultural limitations. My purpose in this paper is to take a different approach and relate the enumeration processes of one of these peoples, the Wari', to the perspectivism that traditionally organized their perceptual world. My hypothesis is that the qualitative indefinition of this universe, where subjects and objects change their forms and affects according to the relational context, has implications for the quantitative instability of the sets that could be counted.
