Li
Ritual and propriety: the shared practices through which a life becomes coherent.
What it commits you to
Li is the ritual repertoire through which dispositions are formed and social roles are given content; it is not external rule but the form that makes virtue legible and transmissible. Confucius's defence of li against law is the point that matters here: what shapes conduct is practised form, not imposed constraint. That is an argument for training rather than for a rule set.
Which realms lean on this
Philosophy carries the arguments the other four kinds are downstream of — what an agent is, what a person owes, what a rule is for.
