It is commonly held that Aristotle's views on politics have little relevance to the preoccupations of modern political theory with authority and obligation. Andres Rosler's original study argues that, on the contrary, Aristotle does examine the question of political obligation and its limits, and that contemporary political theorists have much to learn from him. Rosler takes his exploration further, considering the ethical underpinning of Aristotle's political thought, the normativity of his ethical and political theory, and the concepts of political authority and obligation themselves.
