I am fascinated by religion. (That's a completely different thing from believing in it!) It has had such an incalculably huge effect on human affairs. What is it? What does it represent? Why have we invented it? How does it keep going? What will become of it? I love to keep poking and prodding at it. I've thought about it so much over the years that that fascination is bound to spill over into my writing.
