Dawkins’s 2006 book, The God Delusion, sold around the world, so, perhaps, that answered my question. More seriously, in the wake of 9/11 and in the midst of the anti- scientific demands of American fundamentalists, it could be argued that an anti-religious book was a necessary corrective. There were many such books, the most influential being by the group known as the “four horsemen” of the anti-religious apocalypse – Dawkins, Sam Harris, Christopher Hitchens and Daniel Dennett.

With this book, the philosopher A C Grayling announces himself as the fifth horseman. He is very conscious of being a member of this club. In the acknowledgements, he writes of other anti-religious writers as “comrades in the task” and “colleagues and fellows in the cause”. The cause seems to be to extend a humanist awakening to the people of the world and thereby free them from religion, which is, Grayling admits, “a pervasive fact of history” but also “a hangover from the infancy of modern humanity”.

The book is not intended as a reprise of the arguments of the other horseman comrades; rather, it aims to extend the battlefront. The book is in two halves – the first is Grayling’s case against religion; the second outlines the humanist alternative, which is “an ethics free from religious or superstitious aspects, an outlook that has its roots in rich philosophical traditions”.

First, to take the book on its own terms, this is a lucid, informative and admirably accessible account of the atheist-secular- humanist position. Grayling writes with pace and purpose and provides powerful – though non-lethal – ammunition for anybody wishing to shoot down intelligent theists such as Alvin Plantinga or to dispatch even the most sophisticated theological arguments, such as the ontological proof of the existence of God. That said, the first half, which is in essence analytical, is much better than the second half, which is rather discursive and feels almost tract-like in its evocation of shiny, happy people having fun in a humanist paradise. Nevertheless, this is rhetorically justifiable to the extent that it is an attempt to answer the question necessarily posed by any attempt to eliminate religion – what would be put in its place? Even the most rabid followers of the horsemen cannot seriously deny that religion does serve some useful purposes: providing a sense of community, consoling the bereaved and the suffering, telling a story to make sense of the world, and so on. Grayling tells a humanist story in the belief that it is perfectly capable of answering all these needs.
