In the first book, Aristotle discusses the city ("polis") or "political community" ("koinōnia politikē") as opposed to other types of communities and partnerships such as the household (oikos) and village. The highest form of community is the polis. Aristotle comes to this conclusion because he believes the public life is far more virtuous than the private and because men are "political animals". He begins with the relationship between the city and man (I. 1–2), and then specifically discusses the household ("oikos") (I. 3–13). He takes issue with the view that political rule, kingly rule, rule over slaves and rule over a household or village are only different in size. He then examines in what way the city may be said to be natural.
