“Libby stood at the bar like something that had been hastily added at the end of a painting that hasn't quite dried yet.”

“But I quite like the way you can talk about science without necessarily using mathematics, but using metaphors instead.”

“If you threw a brick at someone you would be responsible for them feeling pain, presumably,' Libby said. 'But if you do the right thing and it makes someone feel bad, isn't that their problem? Then again, how do you even know what the right thing is? Who decides?' 'It's so confusing. I am sure about Mark, but I was sure about Bob before that, and Richard before that. Maybe Mark isn't for ever, I just think he is now when I can't have him. I have to face up to this about myself. I fall in love like that.' She clicked her fingers. 'I always have. For other people, love is like some rare orchid that can only grow in one place under a certain set of conditions. For me it's like bindweed. It grows with no encouragement at all, under any conditions, and just strangles everything else. Good metaphor, huh?”

“Even if you did drop into someone's consciousness, you'd have all their memories and desires and hang-ups right there in front of you. And as you say, in an eternity you'd get the chance to know everything once enough time had passed. You'd become unable to judge anyone.' 'You'd end up being completely compassionate,' I said. 'You wouldn't be able to judge someone once you understood them and their motivations. You'd become them, like Rowan said, and so it would be like judging yourself.”

“One minute I was playing chess and doing maths all the time, the next I had been rerouted into more 'normal' girls' activities: reading, writing stories and worrying about my clothes.”

“I pray for meaning. I pray for the limits of reality to become clear. For a world – and a type of being – that makes sense. I pray for a life after death that is not like this life. I pray for the end of mystery. What would a life be like with all the mysteries solved? If there were no questions, there’d be no stories. If there were no stories, there’d be no language. If there was no language there’d be no . . . What?”

“I'd been pleased to find there was an alternative to the other stuff, which all reminded me of advertisements containing people with perfect teeth, heroic expressions and offspring that looked like they were on their way to Hitler youth rallies.”
