Book excerpt: Joining the ancient debate over the roles of reason and appetite in the moral mind, In Praise of Desire takes the side of appetite. The book makes the claim that acting for moral reasons, acting in a praiseworthy manner, and acting out of virtue amount to nothing more than acting out of intrinsic desires for the right or the good, correctly conceived. In Praise of Desire shows that a desire-centered moral psychology can be richer than philosophers commonly think, accommodating the full complexity of moral life.
