Harrison lives in the Cayman Islands, where he is a newspaper columnist and travel writer. Over the years he has asked ordinary people he meets around the world why they believe in a god, and gotten the same set answers from believers in many religions and cultures. What he does not find is much concern with nuances of philosophy. He sets out 50 of the reasons he has heard over and over, and being a non-believer himself, argues against each one, with bibliographies to cover his back. He does not provide an index.
