About ten years ago I read it from cover to cover, didn't understand a great deal of it

and have forgotten more than I understood.
When I read it, I was just trying to get the general idea of what he was talking about, so I perservered through the mind boggling stuff.
Might try a second go at it now that you've brought it to mind again, that is, after the small stack of books I'm working my way through at the moment.
