That is exactly why perspectivism is not, pace Descola, a subtype of animism, i.e., a schema of practice whose reasons can be known only by the reason of the anthropologist. It is not a type but a concept, and the most interesting use for it consists not so much in classifying cosmologies that appear exotic to us but in counter-analyzing those anthropologies that have become far too familiar. > >Viveiros de Castro (2009) 2014, p. 78. How does ethics link up with mathematics? In many ways more than one. But a simple example may be: to understand what set of unactuated states, what sense of pull, what linearity directs the orientation of a bacterium towards a different temperature than the one it is currently in, one needs to understand something about one's own sense of orientation. Perspectives are everything, and everywhere. And they are implicated at different levels of abstraction: gradients such as temperature. Quality such as smells. Concepts such as negation. [[Ergodicity]], the returning-to-characteristic states quality of a system, can be understood as an example of stacked up perspectives, or levels of abstraction that become actuated. This is why we love to see patterns. Patterns, coarse or fine, large or small, are the evidence of repetition, repetition is the quality of reality where our perspective is instantiated by meeting another thing that is reoccurring/patterning and therefore showing itself as a perspective, to another, which grants us our sense of perspective. Mathematics is the learning of the language that communicates with the most distant of perspectives: "mere" patterns. %% [[Perspectivism notes]]
