Book excerpt: According to Aristotle, man's essential sociality implies a distinctive conception of politics, one in which all political associations exist for the sake of the moral perfection of human beings. This stands in sharp contrast with the modern view of politics that man is not "by nature" political; rather, man chooses to create political associations for the sake of securing the protection of his life and property. Many political theorists have begun to express doubts about this modern view, calling for a return to Aristotle's vision of a politics that is deeply moral. In Aristotle's Politics Today, distinguished political philosophers representing a diversity of approaches examine the meaning, relevance, and implications of Aristotle's political thought for contemporary social and political theory. The contributors engage a broad range of topics, including Aristotle's views on constitutionalism, the extension of Aristotelian ideas to issues in international relations, the place of Aristotelian virtue in modern democratic politics, and Aristotle's conception of justice.
