I'd been wanting to read something semi-modern on anarchy. This pretty well fit the bill. It's not a particularly interesting book though it clarified a notion I already sensed: that anarchists and Marxists have a lot in common. Both want workers to organize and revolt, with the goal of eliminating capitalism and the state. With such a vast and good goal in common, I would have thought I'd see anarchists and Marxists working together more often. (Though, then again, different flavors of Marxists won't work with each other, so...)
