Politics
The word comes from the same Greek word from which the title of Aristotle's book "Politics" (Πολιτικά, "Polis") also derives; "polis" means "affairs of the cities". The book title was rendered in Early Modern English in the mid-15th century as "Polettiques"; it became "politics" in Modern English. The singular "politic" first attested in English 1430 and comes from Middle French "politique", in turn from Latin "politicus", which is the Latinization of the Greek πολιτικός ("politikos"), meaning amongst others "of, for, or relating to citizens", "civil", "civic", "belonging to the state", in turn from πολίτης ("polites"), "citizen" and that from πόλις ("polis"), "city".
Political obligation
Political obligation refers to a moral requirement to obey national laws. Its origins are unclear, however it traces to the Ancient Greeks. The idea of political obligation is philosophical, focusing on the morality of laws, rather than justice. Discussion of political obligation grew during the era of social contract theory, in which Thomas Hobbes and John Locke were crucial in explaining the idea and its importance. Political obligation is distinct from legal obligation.
