This is a remarkable book which has both a beauty as well as energy as metaphorically bracing as any rollercoaster ride, whether or not one might ultimately concur with Ivan Tyrrell and Joe Griffin's reasoning and insights. The book's organising thesis is that there is a way of understanding the origins, structure, evolution and even destiny of the universe, perfectly consistent with much established and respected human knowledge. Moreover, they assert and set out to show how humanity has an essential role to play within the unfolding universe and that our evolution as a species is connected to this purpose. Integral to the enterprise is an explanation of consciousness, which is suggested to pervade the entire cosmos and, within their explanatory model, accounts for the currently unexplained phenomena of dark matter.
Use is made of texts from the fields of archaeology, anthropology, quantum mechanics, psychology, religion and the writings of mystics from several millennia. Each of these areas of human enquiry is drawn upon to make the case for what the authors describe as an up to date "myth" - formulated in a manner consistent with current ways of thinking - and designed to shine light on the nature of reality, as every previous effort of scientific understanding attempted. The end result is very much their own formulation and in total quite unlike anything that has come before (as far as I'm aware at least) - other than the intriguing utterances and poetry of mystics, whom it is claimed have always been referring to the very phenomena which Griffin and Tyrrell suggest explain the underpinnings of reality.
The scope of the material drawn upon in the service of their argument can be breathtaking. Particularly interesting is their respectful reading of the questions and reflections of some of the greatest scientific minds of the last hundred years - including John Wheeler, Albert Einstein, Paul Dirac, Julian Barbour and Robert Oppenheimer - alongside the use of biblical sources. Anyone familiar with previous of the authors' work will recognise the place given to the REM state as having a critical role to play in human development and stability. And the book's first section suggests - as others have too - that the flowering of human development began around forty thousand years ago: the brain's big bang of the book's title. It is suggested that this period saw the emergence of imagination - an example of the REM state working - which made possible a distancing from automatic, instinctual responses and that thereby formed the basis for rationality. The balance between these two states is suggested as possessing huge explanatory power for understanding creativity, pathologies such as psychosis and the nature of the autism spectrum - in fact a new organising idea.
Whilst much in the book presents as creative and reasoned speculation - albeit impressively supported in ways described above - the book ends with an assertion: that the suggested basis of all reality is in fact verifiable. Not by way of laboratory experiment or peer review but by personal experience. This is the science of mysticism but requiring very specific personal qualities and specialised, guided practices.
The book is accessibly written, even if requiring close attention in several places such are its ideas unfamiliar and consequences so thought provoking and potentially even life changing.
Highly recommended.
