Terry Pratchet:
"Time is a drug. Too much of it kills you."
"In the beginning there was nothing, which exploded."
"Give a man a fire and he's warm for a day, but set fire to him and he's warm for the rest of his life."
"The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it."
“Some humans would do anything to see if it was possible to do it. If you put a large switch in some cave somewhere, with a sign on it saying 'End-of-the-World Switch. PLEASE DO NOT TOUCH', the paint wouldn't even have time to dry.”
“In ancient times cats were worshipped as gods; they have not forgotten this.”
“Wisdom comes from experience. Experience is often a result of lack of wisdom.”
“I'll be more enthusiastic about encouraging thinking outside the box when there's evidence of any thinking going on inside it.”
“If you trust in yourself. . .and believe in your dreams. . .and follow your star. . . you'll still get beaten by people who spent their time working hard and learning things and weren't so lazy.”
“She was already learning that if you ignore the rules people will, half the time, quietly rewrite them so that they don't apply to you.”
“The presence of those seeking the truth is infinitely to be preferred to the presence of those who think they've found it.”
“This book was written using 100% recycled words.”
“His philosophy was a mixture of three famous schools -- the Cynics, the Stoics and the Epicureans -- and summed up all three of them in his famous phrase, 'You can't trust any bugger further than you can throw him, and there's nothing you can do about it, so let's have a drink.”
“...inside every old person is a young person wondering what happened.”
“In fact, the mere act of opening the box will determine the state of the cat, although in this case there were three determinate states the cat could be in: these being Alive, Dead, and Bloody Furious.”
“Even if it's not your fault, it's your responsibility.”
“Whatever happens, they say afterwards, it must have been fate. People are always a little confused about this, as they are in the case of miracles. When someone is saved from certain death by a strange concatenation of circumstances, they say that's a miracle. But of course if someone is killed by a freak chain of events -- the oil spilled just there, the safety fence broken just there -- that must also be a miracle. Just because it's not nice doesn't mean it's not miraculous.”
“Many people could say things in a cutting way, Nanny knew. But Granny Weatherwax could listen in a cutting way. She could make something sound stupid just by hearing it.”
“Coffee is a way of stealing time that should by rights belong to your older self.”
"Always remember that the crowd that applauds your coronation is the same crowd that will applaud your beheading. People like a show."
“No! Please! I'll tell you whatever you want to know!" the man yelled.
"Really?" said Vimes. "What's the orbital velocity of the moon?"
"What?"
"Oh, you'd like something simpler?”
“Death: "THERE ARE BETTER THINGS IN THE WORLD THAN ALCOHOL, ALBERT."
Albert: "Oh, yes, sir. But alcohol sort of compensates for not getting them.”
“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.”
“There are, it has been said, two types of people in the world. There are those who, when presented with a glass that is exactly half full, say: this glass is half full. And then there are those who say: this glass is half empty.
The world belongs, however, to those who can look at the glass and say: What's up with this glass? Excuse me? Excuse me? This is my glass? I don't think so. My glass was full! And it was a bigger glass! Who's been pinching my beer?
And at the other end of the bar the world is full of the other type of person, who has a broken glass, or a glass that has been carelessly knocked over (usually by one of the people calling for a larger glass) or who had no glass at all, because he was at the back of the crowd and had failed to catch the barman's eye. ”
