Virtue Ethics
Morality is not about rules or consequences, but about character. Virtue is a habit — the golden mean between excess and deficiency.
In the Nicomachean Ethics, Aristotle proposed that the good life (eudaimonia) is achieved not by following rules (deontology) or maximizing outcomes (consequentialism), but by cultivating virtuous character. Each virtue is a mean between two vices: courage lies between cowardice and recklessness; generosity between stinginess and wastefulness. Crucially, virtue is not a feeling or a belief but a hexis — a stable disposition formed through practice. You become courageous by repeatedly doing courageous things, just as you become a musician by playing music. This connects directly to deliberate practice: moral development, like skill development, requires intentional repetition at the edge of your comfort zone. Phronesis (practical wisdom) is the meta-virtue that tells you what the mean is in any particular situation — it cannot be reduced to an algorithm.
