In this paper I review recent philosophical work in English on the nature of emotion. I begin with the well-known attacks of Bedford, Kenny and Pitcher on what I call the traditional (i.e., Cartesian) view of the nature of emotion. I then trace and discuss the successive alternative views that have been developed in the past thirty years. My aim is both to review the development of these alternative views and to indicate what particular problems have come to be considered (...) the central problems in this area. A comprehensive bibliography of recent work in English is appended. (shrink)
