“Even galaxy-spanning anarchist utopias of stupefying full-spectrum civilisational power have turf wars within their unacknowledged militaries.”

“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.”

“An Outside Context Problem was the sort of thing most civilisations encountered just once, and which they tended to encounter rather in the same way a sentence encountered a full stop.”

“Outright destruction of rebellious ships or habitats - pour encouragez les autres - of course remains an option for the controlling power, but all the usual rules of uprising realpolitik still apply, especially that concerning the peculiar dialectic of dissent which - simply stated - dictates that in all but the most dedicatedly repressive hegemonies, if in a sizable population there are one hundred rebels, all of whom are then rounded up and killed, the number of rebels present at the end of the day is not zero, and not even one hundred, but two hundred or three hundred or more; an equation based on human nature which seems often to baffle the military and political mind.”

“Special Circumstances had always been the Contact section’s moral espionage weapon, the very cutting edge of the Culture’s interfering diplomatic policy, the elite of the elite, in a society which abhorred elitism. Even before the war, its standing and its image within the Culture had been ambiguous. It was glamorous but dangerous, possessed of an aura of roguish sexiness - there was no other word for it - which implied predation, seduction and even violation…No other part of the Culture more exactly represented what the society as a whole really stood for, or was more militant in the application of he Culture’s fundamental beliefs. Yet no other part embodied less of the society’s day-to-day character.”

“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...”

“Though drones, avatars and even humans are one thing; the loss of any is not without moral and diplomatic import, of course, but might be dismissed as merely unfortunate and regrettable, something to be smoothed over through the usual channels. Attacking a ship, on the other hand, is an unambiguous act of war.”
