We begin this chapter with an admission of defeat, but one of which we are not ashamed. The admission is that although we believe that we adequately explain why the occurrence of consciousness is puzzling, we fail to present any really convincing solution to the puzzle. Accordingly, we do not expect you to provide a solution either. It is enough that you come to appreciate the magnitude of the problem. If you do provide a convincing solution, we will consider nominating you for a Nobel Prize.
