Terry Pratchett

The Patrician took a sip of his beer. __ have told this to few people, gentlemen, and I suspect I never will again, but one day when I was a young boy on holiday in Uberwald I was walking along the bank of a stream when I saw a mother otter with her cubs. A very endearing sight, I__ sure you will agree, and even as I watched, the mother otter dived into the water and came up with a plump salmon, which she subdued and dragged on to a half-submerged log. As she ate it, while of course it was still alive, the body split and I remember to this day the sweet pinkness of its roes as they spilled out, much to the delight of the baby otters, who scrambled over themselves to feed on the delicacy. One of nature__ wonders, gentlemen: mother and children dining on mother and children. And that__ when I first learned about evil. It is built into the nature of the universe. Every world spins in pain. If there is any kind of supreme being, I told myself, it is up to all of us to become his moral superior.

Evil in general does not sleep, and therefore doesn't see why anyone else should.

What was it that Granny Weatherwax had said once? "Evil starts when you begin to treat people as things". And right now it would happen if you thought there was a thing called a father, and a thing called a mother, and a thing called a daughter, and a thing called a cottage, and told yourself that if you put them all together you had a thing called a happy family.

You see a wile, you thwart. Am I right?

... it is to your credit that you recognize that if he was a monster then it was other monstrous things which made him so. The iron forged on the anvil cannot be blamed for the hammer...

Rincewind stared, and knew that there were far worse things than Evil. All the demons in Hell would torture your very soul, but that was precisely because they valued souls very highly; evil would always try to steal the universe, but at least it considered the universe worth stealing. But the gray world behind those empty eyes would trample and destroy without even according its victims the dignity of hatred. It wouldn't even notice them.

The flip side of the coin of which Good and Evil are but one side.

It's daft, locking us up," said Nanny. "I'd have had us killed.""That's because you're basically good," said Magrat. "The good are innocent and create justice. The bad are guilty, which is why they invent mercy.

Hell wasn't a major reservoir of evil, any more then Heaven, in Crowley's opinion, was a fountain of goodness; they were just sides in the great cosmic chess game. Where you found the real McCoy, the real grace and the real heart-stopping evil, was right inside the human mind.

TO CHANGE THE FATE OF ONE INDIVIDUAL IS TO CHANGE THE WORLD.

Albert grunted. "Do you know what happens to lads who ask too many questions?"Mort thought for a moment."No," he said eventually, "what?"There was silence.Then Albert straightened up and said, "Damned if I know. Probably they get answers, and serve 'em right.

Measurements is your saving grace if you want to raise steam.

He'd heard that writers spent all day in their dressing gowns drinking champagne. This is, of course, absolutely true.

Furnishing was not a priority in the Citadel. Shelves, stools, tables... There was a rumor among the novices that priests towards the top of the hierarchy had golden furniture, but there was no sign of it here. The room was as severe as anything in the novices' quarters although it had, perhaps, a more opulent severity; it wasn't the forced bareness of poverty, but the starkness of intent.

I am not so blind that I can't see darkness.

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.

... a metaphor ... is like lying but more decorative.

For a moment the rank felt as though they had just returned from single-handedly conquering a distant province. They felt, in fact, tremendously bucked-up, which was how Lady Ramkin would almost certainly have put it and which was definitely several letters of the alphabet away from how they normally felt.
