*The Order of Public Reason*
That is the title, the author is Gerald Gaus of U. Arizona, and the subtitle is A Theory of Freedom and Morality in a Diverse and Bounded World. This is a big and ambitious work, broadly in the liberaltarian tradition, mixing Rawls and Hayek, pondering the implications of disagreement, and experimenting with the idea that morality itself has a coercive element. It is Gaus's attempt to lay out the proper foundations for a liberal society and he summarizes the hard-to-summarize book a bit here.
Also new on the market is Ronald Dworkin's Justice for Hedgehogs. I like the title and I like most of his previous books, but I am not finding this one rewarding to read. Here is one previous debate on related material.
