Of Foucault.

For my reformed dissertation committee, one member who's contributing on methodology advised that I look at early Foucault.

I did, and to tell the truth, I was absolutely surprised at how relevant it was.

People talk about his obsession with social construction so much, you forget sometimes that he really delved into trippy topics for a number of early research projects on the formation of modern disciplines.

The one book that I'm looking at the - "The Archaeology of Knowledge" - is the result of what he learned as a historian, and he really does strip down topics and build them back up again in useful ways, that are really worth considering.

More historians in my circles should really read him, and I'm serious about that.  It's one of the more useful "on historiography" books that I've read.
