Periodically I've suggested that readers wander on over to Crispin Sartwell's blog, Eye of the Storm, for thoughtful, provocative, sometimes infuriating posts. Crispin teaches philosophy at Dickinson College in Carlisle, Pa. He's an anarchist, though of which variety I can't say as I can't keep all the nuances straight; you can ask him if you want to go there. Crispin has also (rarely) commented here at the Cogblog. In my opinion, he can be quite contrarian, whether out of genuine principle or just plain cussedness. In any case, he writes thought-provoking, even poetic, stuff, such as this op-ed style piece on environmentalism.
