Simply by being a resident of a polis can an individual completely seek after an existence of , which is the ultimate objective of human life. Since one can just accomplish this objective through political affiliation, Aristotle reasons that "man is a political creature." As well as shielding private property and censuring free enterprise, Aristotle famously views the foundation of subjection as important to the activities of society. Assessing and reprimanding different constitutions and established hypotheses, Aristotle presumes that no current city or hypothesis is great. He recognizes urban communities with their constitutions and arranges six various types of urban communities, three great and three awful. The three great sorts are politeia, or an established government; nobility; and authority.
