Your life begins when you are born, but your life story begins at that moment when you discover that you are in the wrong family.

Pullman says that people who are tempted to take offence should first see the film or read the books. "They'll find a story that attacks such things as cruelty, oppression, intolerance, unkindness, narrow-mindedness, and celebrates love, kindness, open-mindedness, tolerance, curiosity, human intelligence. It's very hard to disagree with those. But people will."

How will he respond to those attacks? "A soft answer turneth away wrath, as it says in my favourite book." (Proverbs 15:1.)

Several times Pullman reminds me that a work of fiction is not an argument. Perhaps it's safest to say that in "His Dark Materials" he has constructed his own imaginative world so as not to submit to anyone else's. He likes to quote William Blake's line: "I must create a system, or be enslav'd by another man's." His story is a rival to the narratives put forward by two earlier Oxford writers, J.R.R. Tolkien's "The Lord of the Rings" and C.S. Lewis's "The Chronicles of Narnia". Pullman loathes the way the children in Narnia are killed in a car-crash. "I dislike his Narnia books because of the solution he offers to the great questions of human life: is there a God, what is the purpose, all that stuff, which he really does engage with pretty deeply, unlike Tolkien who doesn't touch it at all. "The Lord of the Rings' is essentially trivial. Narnia is essentially serious, though I don't like the answer Lewis comes up with. If I was doing it at all, I was arguing with Narnia. Tolkien is not worth arguing with."
