Kosmos
Order, ornament, and the universe — the Greek word that named the world as an ordered whole and gave English the word cosmos.
The Meaning of Kosmos
Kosmos originally meant order, arrangement, or ornament — the word for a woman's jewelry was kosmēma, and a kosmetikos (beautifier) made things orderly and beautiful. Pythagoras is credited with first applying the word to the universe as a whole — the cosmos was the ordered whole of everything, beautiful precisely through its order. This naming was a philosophical act: to call the universe kosmos was to assert it was orderly rather than chaotic, rational rather than random. The Presocratic project was largely the project of explaining what made the kosmos orderly — what principle (arche) underlay its regularities. For Heraclitus, kosmos was eternal fire flaring and dying in measured proportion; for Anaxagoras, it emerged from the ordering activity of Nous (Mind); for Plato, it was the Demiurge's rational craftsmanship. The term also had political uses: Sparta called its chief magistrates kosmoi (orderers), and the lawgiver who arranged a city was performing the same act as the divine craftsman who arranged the universe.

Fun Fact
The word cosmetics — beauty products — and cosmos — the universe — share the same Greek root: kosmos. The Greek saw no fundamental difference between making a face beautiful and making the universe orderly; both were acts of imposing right arrangement.
