“Real data is messy. ...It's all very noisy out there. Very hard to spot the tune. Like a piano in the next room, it's playing your song, but unfortunately it's out of whack, some of the strings are missing, and the pianist is tone deaf and drunk- I mean, the noise! Impossible! ”

“Years and years ago, there was a production of The Tempest, out of doors, at an Oxford college on a lawn, which was the stage, and the lawn went back towards the lake in the grounds of the college, and the play began in natural light. But as it developed, and as it became time for Ariel to say his farewell to the world of The Tempest, the evening had started to close in and there was some artificial lighting coming on. And as Ariel uttered his last speech, he turned and he ran across the grass, and he got to the edge of the lake and he just kept running across the top of the water — the producer having thoughtfully provided a kind of walkway an inch beneath the water. And you could see and you could hear the plish, plash as he ran away from you across the top of the lake, until the gloom enveloped him and he disappeared from your view.And as he did so, from the further shore, a firework rocket was ignited, and it went whoosh into the air, and high up there it burst into lots of sparks, and all the sparks went out, and he had gone.When you look up the stage directions, it says, ‘Exit Ariel.”

“Words are sacred. They deserve respect. If you get the right ones, in the right order, you can nudge the world a little.”

“We shed as we pick up, like travellers who must carry everything in their arms, and what we let fall will be picked up by those behind. The procession is very long and life is very short. We die on the march. But there is nothing outside the march so nothing can be lost to it. The missing plays of Sophocles will turn up piece by piece, or be written again in another language. Ancient cures for diseases will reveal themselves once more. Mathematical discoveries glimpsed and lost to view will have their time again. You do not suppose, my lady, that if all of Archimedes had been hiding in the great library of Alexandria, we would be at a loss for a corkscrew?”

“A Chinaman of the T'ang Dynasty—and, by which definition, a philosopher—dreamed he was a butterfly, and from that moment he was never quite sure that he was not a butterfly dreaming it was a Chinese philosopher. Envy him; in his two-fold security.”

“My only companion from the outside world during nineteen years of isolation has been my personal hatred of Thursday Next. It's kind of like the old me suddenly taking over, and I promised myself that this was how I would act if I ever saw you.' 'I have the same thing, but with Tom Stoppard,' I said. 'You'd kill Tom Stoppard?' 'Not at all. I promised myself many years ago that I would throw myself at his feet and scream "I'm not worthy!" if I ever met him, so now if we're ever at the same party or something, I have to be at pains to avoid him. It would be undignified, you see—for him and for me.”

“Because children grow up, we think a child's purpose is to grow up. But a child's purpose is to be a child. Nature doesn't disdain what lives only for a day. It pours the whole of itself into the each moment. We don't value the lily less for not being made of flint and built to last. Life's bounty is in its flow, later is too late. Where is the song when it's been sung? The dance when it's been danced? It's only we humans who want to own the future, too. We persuade ourselves that the universe is modestly employed in unfolding our destination. We note the haphazard chaos of history by the day, by the hour, but there is something wrong with the picture. Where is the unity, the meaning, of nature's highest creation? Surely those millions of little streams of accident and wilfulness have their correction in the vast underground river which, without a doubt, is carrying us to the place where we're expected! But there is no such place, that's why it's called utopia. The death of a child has no more meaning than the death of armies, of nations. Was the child happy while he lived? That is a proper question, the only question. If we can't arrange our own happiness, it's a conceit beyond vulgarity to arrange the happiness of those who come after us.”

“That I have the right to express myself freely at all times in all circumstances entails the idea that free speech is a 'basic human right' possessed by each individual, and, as such, trumps the interests of the society or group, including my neighbour.”

“What is the society we wish to protect? Is it the society of complete surveillance for the commonwealth? Is this the wealth we seek to have in common - optimal security at the cost of maximal surveillance?”

“I still believe that if your aim is to change the world, journalism is a more immediate short-term weapon.”

“Chekhov was capable of casually tossing off deplorable comments in his letters, combined with a very modern anger against anti-Semitism.”
