What is it that you do?
I just had a conversation with my friend Dennis about the difference between political philosophy and political theory (as usually taught in Political Science Departments). I tend to think that political philosophy is more normative, that is, its concerned to examine whether or not politics ought to be a certain way, whereas political theory is more interested in explaining the foundations for why politics is the way it is now. For instance, I tend to think political philosophers are more interested in questions of utopia than are political theorists.

1) What Should the Social World Be Like?
2) Should There be Government?
3) What Sort of Government Should We Have?
