This book follows on from 'Secularism: The Hidden Origins of Disbelief', and although the author often refers to it, he runs through the arguments comprehensively so that the book can be successfully read on its own. Postsecularism is written against the background of 9/11 and explores the reactions of both new atheists and religious fundamentalists. Both groups are enraged by extremes of behaviour; the new atheists blame religion whereas the fundamentalists, its absence. Beyond this conflict King shows that another force is emerging, that of the `new defenders of faith', people who pursue questions of spirit without letting go of critical modes of thinking. This is Postsecularism. To examine postsecular thinking he draws on the works of a large array of contemporary thinkers and explores various domains, from Physics to Feminism, from Consciousness Studies to Transpersonal Psychology, Art and the New Age. Mike King engages with what Stephen Gould called NOMA (Non-Overlapping Magisteria), which asserts that the domains of science and religion require a different approach and understanding and the tools used in one, cannot be used to investigate the other. It is against this important premise that Mike King develops the argument that science and spirituality are not competitors in the search for an understanding of Reality, but different ways of examining it, using different resources. From this analysis emerges the understanding of the challenges of extremism and also the context in which postsecular thinking enables Western thought to develop within a framework in which both spirituality and science can retain their integrity. The book is a compelling document of well researched and cross referenced material and the author has a clarity of writing which makes its density accessible and an enjoyable read. Above all it makes sense of the current situation in the West, in which many people see themselves as spiritual but cannot find in organised religion something which resonates with their search. The book is not only a rich source of knowledge, but it also leads to moments of resonance in which we can recognise our own place on the complex spectrum of spirituality.
