Is the mind identical to the functioning brain? If your answer is no, you are a closet dualist. You believe that mind and brain are made of different kinds of stuff. Such a stance will make it hard for you to understand the nature of consciousness. This book is devoted to arguments derived from neurological cases that are aimed at ridding you of your dualism. Another task of this volume is to use neurological cases to support a monist view of consciousness. kconsciousness is the functioning of a material brain that is awake and to which content has been added. To be conscious, therefore, is to be awake and to be aware of something; nothing less, but most importantly, nothing more is required.
