"It provides a formal description of Aztec metaphysics using the vocabulary of Western philosophy: Aztec metaphysics are monistic, non-hierarchical and process-oriented (pretty much the opposite of the ways that we think about reality). It explores different kinds of motion and oppositions that structure the Aztec universe, as well as an overarching metaphor of weaving that provides a model for thinking about the cosmos. Usefully mind-bending."
