General Issues Concerning Online MA/PhD Programs in Philosophy
It's a very good question, Jason, and I'm sorry this won't be the sort of reply you were hoping for!

I am also very interested in the prospect of doing postgraduate research by distance education in philosophy... I'd be interested to see what your research into the efficacy of such programs comes up with.

The only small bit of information I have, is that from my time working in the library at a university in New Zealand. There, I believe, any student could work on a Phd from anywhere in the country. They wouldn't get to work as a tutor, though.

Is that the case in other countries?

p.s. I tried to also contact you personally but couldn't find a way to do it. If you want to discuss, my email is ewan.kingston at gmail.com
