Chris Dillow at Stumbling and Mumbling maintains one of the most consistently intelligent blogs around. He devotes much of his time to dissecting and unravelling the ideology of managerialism, about which he's writing a book I can't wait to read.
And he's particularly good on the extent to which most political commentators in the mainstream media are in thrall to the same ideology. In this post, he suggests that journalists are obsessed with Machiavelli's question, 'How can we win power', and not the more fundamental Platonic question, 'How should we be governed?'UPDATE: I've fixed the links on this post now.
