'WOW, what a great book. As a person who has been in the world of recovery for 30+ years, it goes straight to the heart of the "missing piece" for most alcoholics and addicts.' Dr Robb Kelly, The Addiction Doctor Despite centuries of analyses and debates between scientists and philosophers, consciousness remains puzzling and controversial. It is the most familiar yet mysterious aspect of our lives. There might be different levels of consciousness, or different kinds of consciousness, or just one kind with different features. Modern research into the human brain is yet to provide conclusive answers, and we don't know if animals, insects or plants are conscious, or even the universe itself. The contrasting range of research suggests that a new approach might be needed \-\- one that includes both an objective scientific view and a subjective philosophical and spiritual view \-\- in order to unlock the mystery. All Is One investigates how consciousness fits into a larger picture of the universe by exploring what science, philosophy, religion, and spirituality have to say on the matter, and offers a conclusive definition of consciousness that might satisfy both the scientifically oriented and spiritually oriented reader.
