Everything means something.

I stopped believing there was a power of good and a power of evil that were outside us. And I came to believe that good and evil are names for what people do, not for what they are.

Lord, if I thought you were listening, I'd pray for this above all: that any church set up in your name should remain poor, and powerless, and modest. That it should wield no authority except that of love. That it should never cast anyone out. That it should own no property and make no laws. That it should not condemn, but only forgive.

It's not my business to remedy deaths! It's my business to tell stories. Lyra and the other heroines didn't come with placards saying, "Make this a feminist story!" I'm glad people enjoy seeing a female protagonist in a big adventure story, but I didn't do it for political reasons.

...when all the openings were closed, then the worlds would all be restored to their proper relations with one another, Lyra’s Oxford and Will’s would lie over each other again, like transparent images on two sheets of film being moved closer and closer until they merged–although they would never truly touch.

You cannot change what you are, only what you do.
