I started reading Foucault's Madness And Civilization with the expectation that it would be tedious and incomprehensible. You know, the stereotype that postmodernism / post-structuralism / Continentalism / etc. involves a lot of negation of the negation of the inversion of the Other within the Absolute within [and so on for 200 pages]. There was a little of that. But there was also a fascinating look at the history of mental illness, an entertainingly bombastic writing style, and a few ideas that I might have actually half-understood.
