IN THE MAIL: Ronald Dworkin’s new book, Is Democracy Possible Here?: Principles for a New Political Debate. Dworkin is unhappy with the present polarized state of political debate, and of course he’s right to be. On the other hand, when a lefty author writing on this sort of theme gets a lukewarm review from Publisher’s Weekly it’s a bad sign. Perhaps there will be a civil discussion in the Amazon discussion forum for the book.
