An interesting and original take on the age old idea of the personal Daemon. It treads a curious path between spirituality and science with impressive supporting arguments drawn from the fields of neuroscience, quantum physics, religion and philosophy. The basic tenet is that we have an inner self - our Daemon, a personal and purely psychical entity, who observes our life as we live it. In Peake's theory, we live just once in physical reality, but at the moment of death, time, relative to our own perception, collapses, so we don't actually reach the point of death at all but enter a new state of being in which we relive our former life, this time as a kind of super-real virtual reality re-run. Once in this super real virtual state, we repeat our virtual lives over and over again. However, since the Daemon has been this way before - possibly many times, it can prompt us, unconsciously, to make changes so that our lives are not an exact copy of the one(s) that went before. This means we can change things for the better, and even avoid the disasters that befell us in previous lives. The theory goes a long way towards explaining things like precognition.
I enjoyed the book for its discussion of some extraordinary ideas and I'd say it's worthwhile reading for anyone interested in this kind of thing. However, though I'm quite open to the notion of a personal Daemon, or some other kind of "big mind", I do have reservations about the basic workings of the overall theory, as presented here. I'm always cautious when I read works where "cutting edge" science is used to explain metaphysical concepts - because science, "cutting edge" or otherwise always strikes me as being something of an unsubtle instrument, and when it's not debunking the paranormal, it just ends up making an ass of itself.
The notion of iterative reincarnation described here, chimes very closely with a short story I put out a few years ago called "The Choices" which involved exactly this kind of thing - playing out your life over and over, while each time searching for the one thing that would guide you to a better end, changing your life path for one that's progressively nearer to your originally intended purpose.
However, what I don't get is why it's necessary for us to experience an initial incarnation in "physical" reality at all, since the virtual re-runs are virtually indistinguishable, and to all intents and purposes "real" anyway. Personally, I think the idea of an initial physical reality can be dispensed with, and then what you get is a reworking of the Buddist concept of Maya, which is as old as the hills, but perfectly serviceable for modern times. Nor do I get what the implications are for our relationships with other people in these virtual re-runs. Are they real people or imaginary self-created super-real phantasms?
To me the people we meet in life (virtual or otherwise) have to be real and therefore as in my story "The Choices", the virtual space time continuum is one that we all share, that our separate realities are coincident. There are some parallels here with the idea of conscious creation - the belief that we each create our own universe, and in which it's tempting to treat the others we meet along the way as being included merely for our own entertainment and not as real people at all, so it doesn't matter how unpleasant we are to them. Anyway, I'm rambling on a bit and I don't mean to knock the ideas presented in The Daemon because I'm not really qualified, scientifically, spiritually, or philosophically, and clearly there's a lot of thought gone into this book.
The above reservations excepted, I highly recommend it to all you spiritual hitch-hikers, navigating your way outside of the mainstream! Even if you can't agree with everything it says, it'll get you thinking.
