A traditional view of voluntary action, perception and communication is that each of them involves two distinct elements, one inner or mental and one outer or physical. Voluntary action is held to comprise an inner act of willing, a \"volition,\" and a bodily movement somehow produced by the volition. The papers in this volume constitute a sustained attack on these dualist theories, and a defence of alternative accounts more in keeping with how we ordinarily talk and think. Book is as new except for a few annotations in ink.
