“It made me feel good to know that I could see him and he couldn't see me, and that I was aware and fully conscious and he wasn't”

“What do I really want? he thinks. This is, of course, an extremely good question. It was just such a pity that, life being as it tended to be, it so rarely came as part of a matched pair, with an extremely good answer.”

“It was as if some magnetic repulsion, which before had kept our two carriages from meeting and passing, had now been reversed, and so sucked me inexorably forward, drawing me towards something my heart made clear I feared - or should fear - utterly, in the way some people are fatally attracted towards an abyss while standing on its very edge.”

“In the end, he had to admit, he didn't really understand her. He didn't understand women. He didn't understand men. He didn't even understand children very well. All he really understood, he thought, was himself and the rest of the universe. Neither anything like completely, of course, but both well enough to know that what remained to be discovered would make sense; it would fit in, it could all be gradually and patiently fitted together a bit at a time, like an infinite jigsaw puzzle, with no straight edges to look for and no end in sight, but one in which there was always going to be somewhere for absolutely any piece to fit.”

“It's like a sealed, forgotten chamber in me; I shan't feel complete until I've discovered its entrance.' 'Sounds like a tomb. Aren't you afraid of what you'll find in there?' 'It's a library; only the stupid and the evil are afraid of those.”

“Why had he done it? Why couldn't it just not have happened? Why didn't they have time-travel, why couldn't he go back and stop it happening? Ships that could circumnavigate the galaxy in a few years, and count every cell in your body from light-years off, but he wasn't able to go back one miserable day and alter one tiny, stupid, idiotic, shameful decision...”

“Often I've thought of myself as a state; a country or, at the very least, a city. It used to seem to me that the different ways I felt sometimes about ideas, courses of action and so on were like the differing political moods that countries go through. It has always seemed to me that people vote in a new government not because they actually agree with their politics but just because they want a change. Somehow they think that things will be better under the new lot. Well, people are stupid, but it all seems to have more to do with mood, caprice and atmosphere than carefully thought-out arguments. I can feel the same sort of thing going on in my head. Sometimes the thoughts and feelings I had didn't really agree with each other, so I decided I must be lots of different people inside my brain.”
