Motivational Internalism is a collection of thirteen new essays on exactly the topic you expect it to be, given the title. It also contains an introductory chapter, in which the editors attach an excellent overview of the current state of play to an intimidating bibliography. The essays in the volume are divided into three sections, each with its own, shorter, introduction by the editors. The first section concerns evidence for and against motivational internalism; the second concerns the relevance of internalism for metaethics; the final section considers ways of bridging the gap between internalist and externalist accounts of moral motivation. In what follows I'll comment briefly on each of the essays in these sections before remarking on who, besides libraries, should buy this book.
