Consciousness. Understanding the Ghost in the Machine. New Scientist. Essential Guide N°12. Edited by Richard Webb.

This book doesn't have a definite answer about the nature of consciousness. The reason is that no one has one final answer. The first article starts with "Consciousness is a slippery concept." And the last article starts with "The subjective nature of consciousness makes it difficult even to define." This book explores so many aspects related to consciousness, from subjectivity, experiences, to where consciousness resides in our brains and why we have it. Jump to sleep, anaesthesia and hallucinations. So many different areas of study, so many angles. Hopefully, someday we'll be able to understand. Worth a read.
