On (positive) libertyThere are a lot of interesting blogs with good political theory content. I'll point out posts of potential interest to what we're studying. Here's a blog post by a philosopher on what "liberty" means, and why "liberalism" is a term we shouldn't give up on. It makes, I think, a good point, and might be of some interest for those of you working on the second paper topic--whether you agree with her or not, it might spark some thought.
Here's the money quote:
The whole aim of liberalism is to see it that people have options--that no one is stuck doing the drudge work I did permanently because they don't come from rich families. The market won't make that happen--that is simply an empirical fact.
She illustrates this point with a personal example.
Of course, if you reference her specific arguments in her paper, you'll need to cite them.
