“Eventually scientists will discover something that explains ghosts, just like they discovered electricity, which explained lightning, and it might be something about people's brains, or something about the earth's magnetic field, or it might be some new force altogether. And then ghosts won't be mysteries. They will be like electricity and rainbows and nonstick frying pans.”

“And because there is something they can’t see people think it has to be special, because people always think there is something special about what they can’t see, like the dark side of the moon, or the other side of a black hole, or in the dark when they wake up at night and they’re scared.”

“The word "metaphor" means carrying something from one place to another . . . and it is when you describe something by using a word for something that it isn't. This means that the word "metaphor" is a metaphor.I think it should be called a lie because a pig is not like a day and people do not have skeletons in their cupboards. And when I try and make a picture of the phrase in my head it just confuses me because imagining and apple in someone's eye doesn't have anything to do with liking someone a lot and it makes you forget what the person was talking about.”

“People think that alien spaceships would be solid and made of metal and have lights all over them and move slowly through the sky because that is how we would build a spaceship if we were able to build one that big. But aliens, if they exist, would probably be very different from us. They might look like big slugs, or be flat like reflections. Or they might be bigger than planets. Or they might not have bodies at all. They might just be information, like in a computer. And their spaceships might look like clouds, or be made up of unconnected objects like dust or leaves.”

“A lie is when you say something happened which didn't happen. But there is only ever one thing which happened at a particular time and a particular place. And there are an infinite number of things which didn't happen at that time and that place. And if I think about something which didn't happen I start thinking about all the other things which didn't happen.For example, this morning for breakfast I had Ready Brek and some hot raspberry milkshake. But if I say that I actually had Shreddies and a mug of tea I start thinking about Coco-Pops and lemonade and Porridge and Dr Pepper and how I wasn't eating my breakfast in Egypt and there wasn't a rhinoceros in the room and Father wasn't wearing a diving suit and so on and even writing this makes me feel shaky and scared, like I do when I'm standing on the top of a very tall building and there are thousands of houses and cars and people below me and my head is so full of all these things that I'm afraid that I'm going to forget to stand up straight and hang onto the rail and I'm going to fall over and be killed.This is another reason why I don't like proper novels, because they are lies about things which didn't happen and they make me feel shaky and scared.And this is why everything I have written here is true.”

“...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.”

“Lots of things are mysteries. But that doesn't mean there isn't an answer to them. It's just that scientists haven't found the answer yet.”
