Who is reading this book? Who is conscious of the writing on the page, the attempt to understand and answer the question, or the sounds of revelry in the next room?
Questions about the nature of consciousness are intimately bound up with those about the nature of self because it seems as though there must be someone having the experience; that there cannot be experiences without an experiencer. Our experiencing self seems to be at the centre of everything we are aware of at a given time, and to be continuous from one moment to the next. In other words, self seems to have both unity and continuity. The problems start when you ask what kind of thing that experiencer might be.
