re: verboseness/obfuscation...it is again an unfair generalization. There is nothing at all like that in Lyotard, for example. Lacan, on the other hand, more than fits the bill. And there's a whole gamut somewhere in between the two. As for the intent, I don't share your cynicism. Some are simply more gifted writers than others.
Derrida, Heidegger, Hegel, Foucault, Adorno, (no wait he writes clearly but just writes rubbish about how Kant was a Fascist).



Of all that I read, I most enjoyed Sartre and Kant, although Kant took a few readings to understand what he was on about. Kant's Anthropology from a Pragmatic Point of View is most enjoyable, in particular his discussion of drunkenness.
