Bill Glod interviews me here: http://www.kosmosonline.org/2012/11/28/jason-brennan-on-his-new-book-libertarianism/
My favorite question that he asks (around 11:35) is what should libertarian academics work on right now. I say my overall advice is to work on whatever they find interesting. Don’t feel that your job is to be a spokesperson for an ideology, because doing so would be corrupting.
On that point, I was talking with a colleague yesterday who once had an opportunity to work at a think tank. Personally, I wouldn’t want to work at a think tank. I want to be free to become convinced of, say, Marxism, without having to quit my job.
The last question, around 15:30, is about whether I’m optimistic or pessimistic about liberty in the short-term and long-term. My take: For the world, things look good. For the US, things look bad.
