Greek Mythology Notes

Nomos

concept
Νόμος
law, custom, convention

Human-made law and custom, as opposed to the natural order (physis).

The Myth

Nomos encompassed written law, unwritten custom, musical modes, and mathematical ratios — anything established by human agreement rather than by nature. The Sophists used the physis-nomos distinction to argue that moral rules were mere convention, variable across cultures. Plato countered that true nomos should reflect the natural order. The debate remains alive: are human rights natural (physis) or conventional (nomos)?

Fun Fact

The word "economy" comes from nomos + oikos (household) — literally "household law," reflecting how the Greeks saw financial management as a matter of orderly custom.
