This course explores key concepts and conceptions in political philosophy that are relevant to contemporary societies. Our societies are often not well-ordered, allowing even the unreasonable to hold political power, even in so-called "liberal democratic" societies. Given this reality, it is crucial to examine the existence of political obligation - whether there is a duty to obey laws and institutions - as well as the legitimacy of public and social policies and the role of justice and freedom. This course addresses these fundamental questions through a careful study of political philosophy.
