What Is Theorizing?
Theorizing is an experimental forum for thinking through literature, philosophy, and culture beyond disciplinary boundaries.
Founded and organized by students at the University of Pennsylvania since 1996, Theorizing is a non-profit lecture series. The program is coordinated by graduate students in Penn's Program in Comparative Literature and Literary Theory.
If you follow the links to the archive, you can even listen to audio recordings of many of the lectures. Later today I'll be listening to one of my favorite anthropologists, Alphonso Lingis.
