At the moment, I'm reading two books--fiction and non-fiction as it happens.
Fiction: Life Is Elsewhere by Milan Kundera. A terrific satirical account of how little it takes for writing to become pamphleteering or mere agitprop. Also shows how common it is to regulate aesthetic standards in the name of the common good. There's also a deep, underlying Oedipal theme here, with the poet (our protagonist) simply unable to shake his mother off his consciousness.
Non-Fiction: Bruce Goldstein's work on Cognitive Psychology. Deals with the tensions between the behavioral approach and the cognitive approach and aims to shed light on why the latter might be a bit better. I, for one, am not a big fan of psychology, but it is interesting to read things about it.
