Politics is a work of political philosophy by Aristotle, a 4th-century BC Greek philosopher. The end of the Nicomachean Ethics declared that the inquiry into ethics necessarily follows into politics, and the two works are frequently considered to be parts of a larger treatise-or perhaps connected lectures-dealing with the "philosophy of human affairs". The title of Politics literally means "the things concerning the πόλις polis", and is the origin of the modern English word politics. The literary character of the Politics is subject to some dispute, growing out of the textual difficulties that attended the loss of Aristotle's works. Book III ends with a sentence that is repeated almost verbatim at the start of Book VII, while the intervening Books IV-VI seem to have different flavor from the rest; Book IV seems to refer several times back to the discussion of the best regime contained in Books VII-VIII.[5] Some editors have therefore inserted Books VII-VIII after Book III. At the same time, however, references to the "discourses on politics" that occur in the Nicomachean Ethics suggest that the treatise as a whole ought to conclude with the discussion of education that occurs in Book VIII of the Politics, although it is not certain that Aristotle is referring to the Politics here
