There is a new issue of the always stimulating Dissent magazine online.
It features an article from Norman Geras looking at The Reductions of the Left. Its not the kind of piece you can take a quick taster out of – so you have to read it all.
I also found this article by Andrei S. Markovits of interest. It is a refresher on the European left through the last century and he also has some thoughts on the post-1989 left.
