 The first historians of Mexican philosophy recognized the richness and sophistication of native cosmology, but they did not consider it philosophy per se. However, in 1955, Miguel León-Portilla (1926–2019) challenged the received view and renewed our interest in Mesoamerican thought by publishing his influential La filosofía náhuatl—emphasis on filosofía—a collection of recovered texts translated into Spanish that deal with cosmology, metaphysics, anthropology, ethics, and aesthetics. In his book, León-Portilla argues that the Mexica (i.e., how the Aztecs referred to themselves) in fact did philosophy, and he does so by reconstructing their philosophical tradition and comparing it to Ancient Greek philosophy. Years later, other authors followed his example and wrote extensive commentaries on Mayan texts such as Popol Vuh, which provide a deeper understanding of classical Mayan cosmology and anthropology.
