The variety, breadth, and depth of these essays make the collection well worth exploring. Metaethics has always drawn from other areas of philosophy to make progress, and in this volume you can see that in spades. The emphasis is in using recent developments in the philosophy of language and mind to open the door to new ways of conceiving of moral discourse. It would be unreasonable to expect to find any finished hybrid theories here, as the contributors are still working out the details, but it would be even more unreasonable to ignore the progress being made.
