“When you go to an art gallery you are simply a tourist looking at the trophy cabinet of a few millionaires.”

People seem to think if they dress like a revolutionary they don`t actually have to behave like one.

I don’t know if street art ever really works indoors. If you domesticate an animal, it goes from being wild and free to sterile, fat and sleepy. So maybe the art should stay outside.

If you want someone to be ignored then build a life-size bronze statue of them and stick it in the middle of town. It doesn’t matter how great you were, it’ll always take an unfunny drunk with climbing skills to make people notice you.

You’re mind is working at its best when you’re being paranoid. You explore every avenue and possibility of your situation at high speed with total clarity.

Not everyone will understand your journey. That’s okay. You’re here to live your life, not to make everyone understand.

Modern art is a disaster area. Never in the field of human history has so much been used by so many to say so little.

I know street art can feel increasingly like the marketing wing of an art career, so I wanted to make some art without the price tag attached. There’s no gallery show or book or film. It’s pointless. Which hopefully means something.

Some people represent authority without ever possessing any of their own.

People who get up early in the morning cause war, death and famine.

I used to encourage everyone I knew to make art; I don’t do that so much anymore.

If you have a statue in the city centre you could go past it every day on your way to school and never even notice it, right. But as soon as someone puts a traffic cone on its head, you’ve made your own sculpture.

Some people become cops because they want to make the world a better place. Some people become vandals because they want to make the world a better looking place.

It’s impossible to predict which paintings will last and which won’t. In New Orleans I painted on a dilapidated shop in a street littered with abandoned cars and rotting mattresses, then two hours later the piece was gone. It turned out I’d picked the side of a crack house and the proprietor didn’t like the attention.

I’d been painting rats for three years before someone said ‘that’s clever it’s an anagram of art’ and I had to pretend I’d known that all along.

If you feel dirty, insignificant or unloved, then rats are a good role model. They exist without permission, they have no respect for the hierarchy of society, and they have sex 50 times a day.

If you don’t own a train company then you go and paint on one instead… it all comes from that thing at school when you had to have name tags in the back of something… that makes it belong to you. You can own half the city by scribbling your name over it.

I say that to my colleagues, by the way, in the internal Cabinet meetings, I say, ‘Look, I want to be very clear about what I want.’ I just – I don’t want a peace process, I want a peace result.

Are all Cabinets congeries of little autocrats with a super-autocrat presiding over them?
