I told him I was going to betray you, and betray Lyra, and he believed me because I was corrupt and full of wickedness; he looked so deep I felt sure he'd see the truth. But I lied too well. I was lying with every nerve and fiber and everything I'd ever done...I wanted him to find no good in me, and he didn't. There is none.

I seemed to have spent the whole time either reading, which I loved, or laughing, which I love, or fooling about, which I loved. There was the usual teenage angst: "Nobody understands me" and "I'm the only genius in the world" and all that stuff. But that didn't get very deep.

If a witch needs something, another witch will give it to her. If there is war to be fought, we don't consider cost one of the factors in deciding whether or not it is right to fight. Nor do we have any notion of honor. An insult to a bear is a deadly thing. To us...inconceivable. How could you insult a witch? What would it matter if you did?

This is the value for me of writing books that children read. Children aren't interested in your appalling self-consciousness. They want to know what happens next. They force you to tell a story.

She had asked: What is he? A friend or an enemy? The alethiometer answered: He is a murderer. When she saw the answer, she relaxed at once. He could find food, and show her how to reach Oxford, and those were powers that were useful, but he might still have been untrustworthy or cowardly. A murderer was a worthy companion. She felt as safe with him as she'd done with Iorek Byrnison the armoured bear.

I am a strong believer in the tyranny, the dictatorship, the absolute authority of the writer.
