The temporal ruler of the sprawling city of Ankh-Morpork was sitting in his chair at the foot of the steps leading up to the throne, looking for any signs of intelligence in intelligence reports. The throne had been empty for more than two thousand years, since the death of the last of the line of the kings of Ankh. Legend said that one day the city would have a king again, and went on with various comments about magic swords, strawberry birthmarks, and all the other things that legends gabble on about in these circumstances.
In fact the only real qualification now was the ability to stay alive for more than about five minutes after revealing the existence of any magic swords or birthmarks, because the great merchant families of Ankh had been ruling the city for the last twenty centuries and were as about to relinquish power as the average limpet is to let go of its rock.
The current Patrician, head of the extremely rich and powerful Vetinari family, was thin, tall and apparently as cold-blooded as a dead penguin. Just by looking at him you could tell he was the sort of man you'd expect to keep a white cat, and caress it idly while sentencing people to death in a piranha tank; and you'd hazard for good measure that he probably collected rare thin porcelain, turning it over and over in his blue-white fingers while distant screams echoed from the depths of the dungeons. You wouldn't put it past him to use the word 'exquisite' and have thin lips. He looked the kind of person who, when they blink, you mark it off on the calendar.
Practically none of this was in fact the case, although he did have a small and exceedingly elderly wire-haired terrier called Wuffles that smelled badly and wheezed at people. It was said to be the only thing in the entire world he truly cared about. He did of course sometimes have people tortured to death, but this was considered to be perfectly acceptable behaviour for a civic ruler and generally approved of by the overwhelming majority of citizens. [footnote: The overwhelming majority of citizens being defined in this case as everyone not currently hanging upside down over a scorpion pit.] The people of Ankh are of a practical persuasion, and felt that the Patrician's edict forbidding all street theatre and mime artists made up for a lot of things. He didn't administer a reign of terror, just the occasional light shower.

He stalked away through the ruined palace, Vimes trailing behind, until he reached the Oblong Office. It was quite tidy. It had escaped most of the devastation with nothing more than a layer of dust. The Patrician sat down, and suddenly it was as if he'd never left. Vimes wondered if he ever had.
He picked up a sheaf of papers and brushed the plaster off them.
'Sad,' he said. 'Lupine was such a tidy-minded man.'
'Yes, sir.'
The Patrician steepled his hands and looked at Vimes over the top of them.
'Let me give you some advice, Captain,' he said.
'Yes, sir?'
'It may help you make some sense of the world.'
'Sir.'
'I believe you find life such a problem because you think there are the good people and the bad people,' said the man. 'You're wrong, of course. There are, always and only, the bad people, but some of them are on opposite sides.'
He waved his thin hand towards the city and walked over to the window.
'A great rolling sea of evil,' he said, almost proprietorially. 'Shallower in some places, of course, but deeper, oh, so much deeper in others. But people like you put together little rafts of rules and vaguely good intentions and say, this is the opposite, this will triumph in the end. Amazing!' He slapped Vimes good-naturedly on the back.
'Down there,' he said, 'are people who will follow any dragon, worship any god, ignore any iniquity. All out of a kind of humdrum, everyday badness. Not the really high, creative loathsomeness of the great sinners, but a sort of mass-produced darkness of the soul. Sin, you might say, without a trace of originality. They accept evil not because they say yes, but because they don't say no. I'm sorry if this offends you,' he added, patting the captain's shoulder, 'but you fellows really need us.'
'Yes, sir?' said Vimes quietly.
'Oh, yes. We're the only ones who know how to make things work. You see, the only thing the good people are good at is overthrowing the bad people. And you're good at that, I'll grant you. But the trouble is that it's the only thing you're good at. One day it's the ringing of the bells and the casting down of the evil tyrant, and the next it's everyone sitting around complaining that ever since the tyrant was overthrown no-one's been taking out the trash. Because the bad people know how to plan. It's part of the specification, you might say. Every evil tyrant has a plan to rule the world. The good people don't seem to have the knack.'
'Maybe. But you're wrong about the rest!' said Vimes. 'It's just because people are afraid, and alone—' He paused. It sounded pretty hollow, even to him.
He shrugged. 'They're just people,' he said. 'They're just doing what people do. Sir.'
Lord Vetinari gave him a friendly smile.
'Of course, of course,' he said. 'You have to believe that, I appreciate. Otherwise you'd go quite mad. Otherwise you'd think you're standing on a feather-thin bridge over the vaults of Hell. Otherwise existence would be a dark agony and the only hope would be that there is no life after death. I quite understand.' He looked at his desk, and sighed. 'And now,' he said, 'there is such a lot to do. I'm afraid poor Wonse was a good servant but an inefficient master. So you may go. Have a good night's sleep. Oh, and do bring your men in tomorrow. The city must show its gratitude.'
'It must what?' said Vimes.
The Patrician looked at a scroll. Already his voice was back to the distant tones of one who organizes and plans and controls.
'Its gratitude,' he said. 'After every triumphant victory there must be heroes. It is essential. Then everyone will know that everything has been done properly.'
He glanced at Vimes over the top of the scroll.
'It's all part of the natural order of things,' he said.
After a while he made a few pencil annotations to the paper in front of him and looked up.
'I said,' he said, 'that you may go.'
Vimes paused at the door.
'Do you believe all that, sir?' he said. 'About the endless evil and the sheer blackness?'
'Indeed, indeed,' said the Patrician, turning over the page. 'It is the only logical conclusion.'
'But you get out of bed every morning, sir?'
'Hmm? Yes? What is your point?'
'I'd just like to know why, sir.'
'Oh, do go away, Vimes. There's a good fellow.'
