The concept of unity will be discussed in relation to modernity, arguing that this concept is supported by the ideological mechanisms of religion and the state. Though the latter has undergone “reformist” processes through political praxis, the modern state bases its primary criteria on a regime of symbolic unity, in which religion is a space for sustaining and codifying justice, order and purification, even if through the collective unconscious. On the one hand, modernizing reforms concealed this space, and on the other, they substituted symbols and discourses but not symbolic mechanisms. We aim to detheologize Indigenous mythologies and semiotics in order to disarticulate the symbolic power exercised by an institutionality that is closed in on itself, in which culture became a propaganda accessory synthesized in “art” and the “artistic,” thus favoring institutionality. In this light, we aim to explain the concept of Teponazcuauhtla, making possible a comparative epistemology between two civilizations with different natures: that which is derived from the Greco-Latin model, and that which exists surreptitiously, beyond the invention of Indigenism, lacking axiology, unity, nature. This discussion is enriched through an explanation of key notions of Mesoamerican geometry and logic, which are quite distinct from the Euclidean tradition.
