A frank discussion on whether to go to grad school

Although I don't agree with him on much, I found this post by Jason Brennan a refreshingly frank--and accurate--discussion on the pro's and con's of grad school, what it takes to succeed in grad school, the many different ways and points that a grad school experience can unexpectedly go off the rails, and what life in the academy is like post-grad school. A must-read, in my opinion, for anyone considering a PhD in philosophy.
