Aztec Virtue Ethics

Western moral philosophy, from Plato through Kant, tends to locate virtue in the individual. You develop good character, exercise practical reason, and make correct moral choices through the strength of your own will. The Aztec philosophical tradition — preserved in Nahuatl texts recorded by Catholic priests in the 16th and early 17th centuries — offers a different framework that challenges this individualism at every point.¹

The Slippery Earth

The Aztecs had a saying: tlalticpac — the earth is slippery, slick. "Perhaps at one time, one was of good life; later, he fell into some wrong, as if he had slipped in the mud." Where Plato's Republic ends with the myth of Er, in which the truly virtuous can beat chance itself — Odysseus picking the right life even with the worst draw — the Aztecs would never have written such a story. No matter how virtuous you are, there's always the possibility that a younger, more skilled, more impetuous man with a sword will strike you down. And you yourself are always prone to slipping, despite your best upbringing.¹

This sounds like pessimism, but the Aztec thinkers drew a different conclusion from it. If individual perfection is impossible, the goal isn't to become a moral saint but to lead a rooted life — neltiliztli, literally "rootedness." In a rooted life, you manage your mistakes well rather than avoid them altogether. The reward isn't happiness (the Aztecs saw no conceptual link between virtue and pleasure) but worthwhileness. Their image of the virtuous person was closer to Homer's Hector — the supporting beam for the house of Troy, to whom everyone fled for refuge, but who was nevertheless undone — than to Odysseus the clever survivor.

The Middle Way

Aztec virtue ethics shares the idea of a mean with Aristotle, but frames it spatially rather than analytically. A mother tells her daughter: "On earth we live, we travel along mountain peaks. Over here there is an abyss, over there is an abyss. If thou goest over here, or if thou goest over there, thou wilt fall in. Only in the middle — tlanepantla — doth one go, doth one live."¹

The middle way is context-dependent in ways that would make a universalist uncomfortable. The apt expression of an action depends on circumstances, social position, social role, and whether a specific rite is being performed. Public drunkenness in Tenochtitlan was punished by death for nobles. But at a wedding, the elderly were not only permitted but expected to get drunk. There was no formal test for the mean — you developed a sense for it the way we speak of someone having impeccable style or an intuitive grasp of human relations.

Virtue as Cooperative Practice

Here's where the Aztec system diverges most sharply from the Western tradition. For Aristotle, the phronimos — the person of practical wisdom — is a rare individual. This is why Aristotle thought monarchy was the ideal government: rule by the single wisest person. The Aztecs thought practical reason worked best in groups, and you find evidence for this everywhere: in merchant rites, in the choice of schools for children, in the deliberations of the king himself.¹

When Aztec merchants prepared to travel to another city, they selected an auspicious day, made offerings, then gathered the leaders of their neighborhood in a circle arranged by seniority. The leaders gave advice about the journey, contingency plans, and urged moral virtues needed for dealing with foreigners. This wasn't just ceremony — it was a socially acceptable mechanism for exchanging relevant information and refreshing moral commitments. The young merchants were arranged to travel with experienced ones, on the reasoning that "perhaps, with their help, he will become prudent, mature, understanding."

The Aztecs also weighed advice unequally, giving greater weight to those with the most practical experience — ixtlamatiliztli — who were often the elderly. This is neither democracy nor aristocracy but something closer to meritocratic deliberation, where the meritocracy is measured in lived experience rather than abstract reasoning ability.

Moral education, for the Aztecs, never ended. Even the king was admonished by elders. The virtues had to be sustained and retrained throughout life through social rituals, community deliberation, and mutual accountability. This makes sense if you take the slippery earth metaphor seriously: if anyone can fall at any time, the best guard against falling isn't individual strength of character but having someone there to catch you. "Wisdom in human affairs consists in the recognition that the best we can do is to learn to stand with the help of others, to alter our circumstances for the better, and to clasp hands so that we can pull ourselves back up when we fall."¹

The connection to cultural evolution is worth noting. Henrich's work argues that culturally evolved practices work for reasons nobody individually understands, and that the most dangerous thing you can do is think for yourself instead of following tradition. The Aztec system provides a philosophical framework for the same insight: the locus of wisdom is the community, not the individual, and the role of the individual is to remain embedded in and accountable to the group. Whether this is a feature or a bug depends on whether you think the Western emphasis on individual moral autonomy has been a net positive — a question that the slippery-earth metaphor suggests we should approach with more humility than we usually do.
