The Politics is a work of political philosophy by Aristotle, who characterizes men as "political animals" and claims that the city (polis) is the highest type of community. Aristotle discusses family matters, slaves and property, as well as governments, claiming that public virtue is greater than private virtue. While creating theoretical definitions for good governments (royalty, aristocracy, constitutional) and their corrupted variants (tyranny, oligarchy, democracy, respectively), Aristotle also analyzes the actual governments of various Greek cities.
