Oswald Spengler's "Der Untergang des Abendlandes" monolith of history's philosophy and comparison between historical ages, analyzed through the lens of the culture's morphology, inherited mainly from Goethe. Extremely hard to follow, one has to dispose over quite a high personal cultural level to be able to stay behind the text and understand everything properly. For a more massive dose of masochism, I am reading it in the original language. I am reading it quite slowly (I started it last autumn), interrupting it from time to time, and starting back after a while, because it was way too hard to follow continuously and I am quite sure I will have to revisit it in the future.
