The modern-day descendants of the Nawa peoples have inherited a complex cosmovision from their indigenous ancestors. This philosophical and scientific achievement is the product of a thorough and disciplined observation of the natural world. In Our Slippery Earth, Kurly Tlapoyawa asserts that there is a logical evolution of the Nawa cosmovision from that of a myth-based set of beliefs to a more scientific worldview grounded in pantheism. This evolution represents a profound philosophical process that allows modern day descendants of Mesoamerican civilizations to maintain their traditions in the modern world.
