Hi all: I recently graduated law school and have work lined up for the next 2 years. During my last year of law school I took a graduate political theory seminar that awakened me from the unstimulating environment of law school. Since then, I have been devouring works of political theory that I hadn't really thought about much since undergrad, and I have become very interested in the idea of research and writing in the field. However, I have read so much about how difficult it is to land a tenure-track position, and, due to family circumstances, I am fairly limited geographically. Thus, while there are 3-4 very good programs w/in my local area, I don't really have the flexibility to move to pursue a position. I wouldn't mind teaching at a community college or a two-year college, or even just returning to a law practice or working in government. I desperately, however, want the intellectual experience and expertise in the field that I think grad school would provide. It doesn't really matter to me if I ultimately land a tenure-track position. In other words, my question is: Is it worth pursuing a PhD as an end in itself, or am I barking up the wrong tree? Should I instead just be content to read about the subject in my own time? Thanks to everybody in advance.
