Matt Yglesias makes an intriguing point about the intersection of punk rock and academia:
I think the punk scene and the humanistic branches of the academy have some important things in common. They both involve a kind of deep rejection of the logic of market exchange.
I sort of see Matt's point. Academia does serve as a refuge for a great many people who aren't really eager to submit to the demands of ordinary life in capitalist society. Academics don't keep the same schedules that people with "real jobs" typically do. We often produce work that is of little to no inherent commercial value, and we often speak meaningfully and forcefully about the need to "keep our integrity, man!"
On the other hand, as some of Matt's commentors point out, Academia, like punk rock, depends for its rejection of a capitalist ethos on the tolerance and largesse of precisely the capitalist system that, either implicitly or explicitly, we are engaged in the process of rejecting.
On the other, other hand, the liklihood that I'll have a chance to compare myself to Joe Strummer again any time in the foreseeable future is exceedingly unlikely (except in the sense of "Joe Strummer was a really good guitarist, as opposed to Scott Paeth, who isn't"), so I'll take my opportunities as they come!
