I've been spread over several books recently.
Just finished the Communist Manifesto for a reading group, I was right in thinking there was no actual theory in there I didn't already know, however it did give me some nice ways to phrase certain arguments.
I've also been reading The Soul of Man Under Socialism which just flows beautifully, about half way through but haven't been able to get around to finishing it due to having no time.
Re-reading State and Revolution for another reading group, as it was the first book I read, coming back to it with more knowledge on the Russian revolution and Marxist theory has caused me to pick up a lot more than I did the first time round. Instead of stumbling through and just about keeping up with the concepts, I'm actually evaluating them in my head as I go along, which feels nice.
I've also been reading Critique of the Gotha Program, probably read the half half of that three times now and still I'm picking out new stuff, but this time around I think I've properly got my head around the details, of which there are many. Will have that finished pretty soon, it's a great text.
And lastly I need to finish off the extremely long winded Zizek part of Revolution at the Gates. I was tempted to drop it all together but I've been told he brings together all the waffling at the end to make some great points, and as I found his intro to the book amazing I'm optimistic his final points, now that I actually know he makes some eventually, will be good, so that's given me an incentive to get back into it.
So yea, kind of all over the place at the moment. Exams are coming up too but I hope during summer I'll be able to wrap all of these up.
