“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...”

“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”

“People were always sorry. Sorry they had done what they had done, sorry they were doing what they were doing, sorry they were going to do what they were going to do; but they still did whatever it is. The sorrow never stopped them; it just made them feel better. And so the sorrow never stopped.”

“But it was pointless, it was stupid; he thought about thoughtless things. If I were a seabird . . . but how could you be a seabird? If you were a seabird your brain would be tiny and stupid and you would love half-rotted fish guts and tweaking the eyes out of little grazing animals; you would know no poetry and you could never appreciate flying as fully as the human on the ground yearning to be you.If you wanted to be a seabird you deserved to be one.”

“Our lives are about development, mutation and the possibility of change; that is almost a definition of what life is: change... If you disable change, if you effectively stop time, if you prevent the possibility of the alteration of an individual's circumstances — and that must include at least the possibility that they alter for the worse — then you don't have life after death; you just have death.”

“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.”

“He could not believe that ordinary people in the Culture really wanted the war, no matter how they had voted. They had their communist Utopia. They were soft and pampered and indulged, and the Contact section’s evangelical materialism provided their conscience-salving good works. What more could they want? The war had to be the Mind’s idea; it was part of their clinical drive to clean up the galaxy, make it run on nice, efficient lines, without waste, injustice or suffering. The fools in the Culture couldn’t see that one day the Minds would start thinking how wasteful and inefficient the humans in the Culture themselves were.”
