“Vimes took the view that life was so full of things happening erratically in all directions that the chances of any of them making some kind of relevant sense were remote in the extreme. Colon, being by nature more optimistic and by intellect a good deal slower, was still at the Clues are Important stage.”

“Sam Vimes could parallel process. Most husbands can. They learn to follow their own line of thought while at the same time listening to what their wives say. And the listening is important, because at any time they could be challenged and must be ready to quote the last sentence in full. A vital additional skill is being able to scan the dialogue for telltale phrases such as "and they can deliver it tomorrow" or "so I've invited them for dinner?" or "they can do it in blue, really quite cheaply.”

“The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.This was the Captain Samuel Vimes 'Boots' theory of socioeconomic unfairness.”

“There were plotters, there was no doubt about it. Some had been ordinary people who'd had enough. Some were young people with no money who objected to the fact that the world was run by old people who were rich. Some were in it to get girls. And some had been idiots as mad as Swing, with a view of the world just as rigid and unreal, who were on the side of what they called 'the people'. Vimes had spent his life on the streets, and had met decent men and fools and people who'd steal a penny from a blind beggar and people who performed silent miracles or desperate crimes every day behind the grubby windows of little houses, but he'd never met The People.People on the side of The People always ended up disappointed, in any case. They found that The People tended not to be grateful or appreciative or forward-thinking or obedient. The People tended to be small-minded and conservative and not very clever and were even distrustful of cleverness. And so the children of the revolution were faced with the age-old problem: it wasn't that you had the wrong kind of government, which was obvious, but that you had the wrong kind of people.As soon as you saw people as things to be measured, they didn't measure up. What would run through the streets soon enough wouldn't be a revolution or a riot. It'd be people who were frightened and panicking. It was what happened when the machinery of city life faltered, the wheels stopped turning and all the little rules broke down. And when that happened, humans were worse than sheep. Sheep just ran; they didn't try to bite the sheep next to them.”

“There are all kinds of darkness, and all kinds of things can be found in them, imprisoned, banished, lost or hidden. Sometimes they escape. Sometimes they simply fall out. Sometimes they just can't take it any more.”

“...there was a general murmuring, no real words, nothing that would get anyone into trouble if the piper turned nasty, but a muttering indicating, in a general sense, without wishing to cause umbrage, and seeing everyone's point of view, and taking one thing with another, and all things being equal, that people would like to see the boy given a chance, if it's all right with you, no offence meant.”

“We're dealing here," said Vimes, "With a twisted mind.""Oh, no! You think so?""Yes.""But... no... you can't be right. Because Nobby was with us all the time.""Not Nobby," said Vimes testily. "Whatever he might do to a dragon, I doubt if he'd make it explode. There's stranger people in this world than Corporal Nobbs, my lad."Carrot's expression slid into a rictus of intrigued horror."Gosh," he said.”
