A lovely take-down by Rob Jubb.
When I was in my last year of undergrad (which was my third), I lived in a single room in the most party-oriented wing of the campus's party dorm. Except for a handful of people who knew me from before, everyone in the wing called me The Guy, because they never saw me; while they were partying, I was at the library or studying in my room or visiting friends. I somehow missed the partying-through-4-years-of-college use of philosophy (perhaps it was counteracted by my being a double major), but I will add it to my list.
