Cartesian Sonata and Other Novellas - William H. Gass I taught this in an advanced undergraduate philosophy course in Postmodernism, and it was a mixed success. The individual sentences that Gass writes are simply awesome, and the complexities of character/author relationships are very interestingly pursued. We read it along with Barthes on authorship, it produced a good conversation, but without much to resolve in the specific images and characters that Gass introduces. I'll look forward to reading some of his earlier work.
