Even within a political community, there may be sharp disagreements about the role and purpose of government. Some want an active, involved government, seeing legal and political institutions as the means to solve our most pressing problems, and to help bring about peace, equality, justice, happiness, and to protect individual liberty. Others want a more minimal government, motivated, perhaps, by some of the disastrous political experiments of the 20th Century, and the thought that political power is often just a step away from tyranny. In many cases, these disagreements arise out of deep philosophical disagreements.

All political and legal institutions are built on foundational ideas. In this course, we will explore those ideas, taking the political institutions and political systems around us not as fixed and unquestionable, but as things to evaluate and, if necessary, to change. We will consider the ideas and arguments of some of the world's most celebrated philosophers, including historical thinkers such as Plato, Hugo Grotius, David Hume, Thomas Jefferson, and James Madison, and more contemporary theorists such as Michelle Alexander, Kwame Anthony Appiah, Bryan Caplan, Angela Davis, Ronald Dworkin, Jon Elster, John Hart Ely, H.L.A. Hart, Michael Huemer, Andrew Rehfeld, and Jeremy Waldron.
