Abstract
In addition to his study of correct constitutions, Aristotle investigated the entire spectrum of regimes existing in his day. Aristotle believes that it is a proper task for politics and legislation to deal with deviant or imperfect constitutions such as oligarchy and democracy. In seeking to preserve and reform imperfect constitutions and prevent revolution, Aristotle employs a maxim of superiority: that the part of the polis that supports the constitution ought to be superior to the part that does not. Although this maxim can clearly come into conflict with justice, Aristotle regards it as a defensible normative precept when it is the closest feasible approximation to justice that is attainable under adverse circumstances.
