Books are authored by countless people and credited to only one. They each represent little kingdoms of thought built from the toil of others that gratify the tiny tyrant who chained the disparate ideas together. If I were to begin to thank all those who have helped to steer my thinking, it would be a long list. With that in mind, I will stick to thanking those who were directly involved with encouraging me in this particular work. My thanks go to Ian Mitchell, the one who said that I ought to publish a book on this subject; Alison Barr, who opened up the way for it to be published; and Andrew King and Cary Gibson, who helped render the material publishable. My deep thanks also go to Brian McLaren, Phyllis Tickle, Jonny Baker, Helena Macormac, the Ikon ‘cyndicate’, Francie and my parents.
