A Theory of Everything sets out Wilbers' groundbreaking theory and shows how it can apply to the real world of struggle, suffering, frustration and joy. Wilber stresses the importance of the term 'integral', which he sees as essential if 'inner and outer' are to be honoured and to be allowed to work together. His complex cutting-edge theories and models integrate the realms of body, mind, soul and spirit and are presented in a clear and readable way. Wilber looks at the historical development of human thought and behaviour, as expressed through spirituality and science. He illustrates that we can heal the split between spirituality and science by recognising that each is essential to its different territory, and believes that 'spirit' is the causal factor from which all states arise.

The book is divided into three main sections:
 Firstly, Wilber sets out his complex models and theory
 Secondly, he applies these to real world problems in such fields as politics, medicine, business, education and the environment
 Finally, Wilber discusses daily practices that readers can use to apply this integrative vision to their own lives

This is a compelling read, and has the potential to impact forcefully on all walks of life, for those who take it on board and are prepared to work at it. It also, usefully, offers an alternative mindset for those of us who have perhaps passed judgement on how 'spiritual' the worlds of business, politics, medicine or education are.

I cannot claim to understand fully, this exciting and inspiring book (I have not yet studied the 40 odd pages of explanatory notes) but I sense its importance and relevance to me, and my developing beliefs.
