Mark Haddon

"I think people believe in heaven because they don't like the idea of dying, because they want to carry on living and they don't like the idea that other people will move into their house and put their things into the rubbish."

"I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them"

"And it's best if you know a good thing is going to happen, like an eclipse or getting a microscope for Christmas. And it's bad if you know a bad thing is going to happen, like having a filling or going to France. But I think it is worst if you don't know whether it is a good thing or a bad thing which is going to happen."

"And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don’t even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in you life it is nice to think that they are what is called negligible, which means they are so small you don’t have to take them into account when you are calculating something."

"I like poetry when I don't quite understand why I like it. Poetry isn't just a question of wrapping something up and giving it to someone else to unwrap. It just doesn't work like that."

"I am really interested in eccentric minds. It's rather like being fascinated by how cars work. It's really boring if your car works all the time. But as soon as something happens, you get the bonnet up. If someone has an abnormal or dysfunctional state of mind, you get the bonnet up."

"Use your imagination, and you'll see that even the most narrow, humdrum lives are infinite in scope if you examine them with enough care."

"Things can be funny when people are uneasy. It softens them up and stops them falling asleep on the sofa. I like those moments where people half-smile and half-wince."

"Reading is a conversation. All books talk. But a good book listens as well."

"And all I could see would be stars. And stars are the places where the molecules that life is made of were constructed billions of years ago. For example, all the iron in your blood which stops you from being anemic was made in a star."

"...most people are almost blind and they don’t see most things and there is lots of spare capacity in their heads and it is filled with things which aren’t connected and are silly, like, “I’m worried that I might have left the gas cooker on."

"I don't remember deciding to become a writer. You decide to become a dentist or a postman. For me, writing is like being gay. You finally admit that this is who you are, you come out and hope that no one runs away."

"Appalling things can happen to children. And even a happy childhood is filled with sadnesses. Is there any other period in your life when you hate your best friend on Monday and love them again on Tuesday? But at eight, 10, 12, you don't realise you're going to die. There is always the possibility of escape. There is always somewhere else and far away, a fact I had never really appreciated until I read Gitta Sereny's profoundly unsettling Cries Unheard about child-killer Mary Bell. At 20, 25, 30, we begin to realise that the possibilities of escape are getting fewer. We begin to picture a time when there will no longer be somewhere else and far away. We have jobs, children, partners, debts, responsibilities. And if many of these things enrich our lives immeasurably, those shrinking limits are something we all have to come to terms with. This, I think, is the part of us to which literary fiction speaks."
