After many years of neglect, philosophers are increasingly turning their attention to the emotions, and recently we have seen a number of different accounts of emotion. In this article, we will first consider what facts an account of emotion needs to accommodate if it is going to be acceptable. Having done that, we will then consider some of the leading accounts and see how they fare in accommodating the facts. Two things in particular will emerge. First, an adequate account of emotion cannot be provided without taking into account a wide range of issues in philosophy of mind that extend beyond the emotions in particular. Secondly, the diversity of emotional phenomena makes it especially hard to provide anything like a comprehensive account of emotion; philosophers not only disagree over what are the essential properties of emotion, but also over what are central cases.
