Most political debate is superficial. If you want superficial debate, you need only turn on cable news. Political philosophy is for people who want to understand and debate the deep questions.

People debate whether its more just for the rich to pay a 40% or 38% marginal tax rate. They rarely ask the deeper questions: Why should we be forced to pay taxes at all?

People debate whether we should speed up the process for immigrants to become nationalized, or how many skilled immigrants we should allow in. They rarely ask the deeper questions: Why should we divide the world into nation-states with strict territorial borders in the first place? If I want to hire a Haitian to clean my house, why should the rest of you be allowed to stop me?

People debate whether congressional districts are gerrymandered or whether voters should be required to show ID. They rarely ask the deeper questions: Why should our fellow citizensmost of whom know nothing or less than nothing about politicsget to decide who gets to lead the country? Why not instead, say, limit the right to vote to people who can pass the US citizenship exam, or who show a basic understanding of economics and history?

People debate whether a too-big-to-fail corporation should get a bail out. They debate whether a local government should use its power of eminent domain to transfer land from poor people to General Motors. They rarely ask the deeper questions: Why should we allow limited-liability corporations to exist in the first place? Why should anyone be able to claim land as her own? Why not instead hold that the world and all its resources belong to all us equally?

People debate whether the American police are too brutal and violent, and what can be done to make the police force more civil. But they rarely ask the deeper questions: Why should we create governments in the first place? A government claims a monopoly on the use of violence to create and enforce rules. If it would be bad for, say, Walmart or Target to become monopolies, why would we want a monopoly on the coercive power? Why shouldnt I be allowed to choose which police force will protect me, just as I can choose where to shop for clothes or food?

Political philosophy is the branch of philosophy that asks and attempts to answer these deeper questions. There are many other questions: Which matters more, individuals or the community as a whole? What kind of government, if any, ought we have, and what should it be permitted and forbidden to do? Do we have any moral obligation to obey our governments laws and commands? What rights do people have, and why? Should be people be allowed to own private property? If they dont have enough property to live well, should the government provide it through tax-funded welfare programs? Should people be free to choose what to eat, how to live, what to worship, what to say, or on what terms they will work? Is it important that everyone have equal opportunity to succeed? Should we make sure everyone ends up equally successful? Should people be allowed to emigrate freely? When, if ever, is war justifiable? Whats more important, liberty or equality? And what exactly is liberty, anyways? Of all the ways people could be equal, which, if any, matter from the standpoint of justice?

We manage to live together peacefully (more or less) because we accept and live by commonly accepted rules. I dont show up at your house to drink your beer, and you dont snatch my car out of the parking lot. When we come to a four-way stop sign, we all know what to do. I dont tell you not to let your kids play Minecraft, and you dont forbid me from letting mine have ice cream. You dont force me to attend your church, and I dont force you to stay away from yours.

Our lives are governed by many such rules, most of which we rarely notice or think about. Economists refer to the various rules of social life as institutions. Institutions are the rules of the game that structure our lives together. For example, if you think about it, democracy and monarchy are really a set of rules about who gets to make the rules. The institution of marriage is a set of rules about how to allocate and control property, children, and sex. The institution of private property is a set of rules about who gets to use, modify, trade, and destroy various external goods.

The main goal of political philosophy is to determine the standards by which to judge different institutions good or bad, just or unjust.

Some people might think they dont have much need of political philosophy: Who cares about wishy-washy obtuse notions of justice? Im a pragmatist. I just want to know what works.

But this isnt a way of avoiding political philosophy; its a way of being dogmatic about it. After all, before we can just do what works, we have to know what counts as working. I look at a system in which both the poor and the rich are getting richer and think, Its working! A friend looks at that same system, sees the income gap between the poor and rich growing, and thinks, Its not working. We can both pound the table and call ourselves pragmatists. But at the end of the day, were divided not by our lack of pragmatism, but by our different political philosophies.

John Rawls, an eminent twentieth-century political philosopher, Rawls says that theories of justice are about assigning the rights and duties and determining the proper distribution of benefits and burdens of social cooperation.1 What make different political philosophies distinct from one another is what rights and duties they think people ought to have, what principles they think determine the proper distribution of benefits and burdens ought to be, and most fundamentally, what they regard as a society.

The purpose of this primer in political philosophy is to introduce you to some of the major theories of justice, to see some of the arguments philosophers have adduced for and against these theories, and, ultimately, to help you be more thoughtful and rigorous in your own thinking. My goal is to supply you with questions more so than answers.
