I recognize that I have the ability to be selfish, but I also recognize that you can't be happy if you only care about yourself at the expense of other people.

Of all the consumer products, chewing gum is perhaps the most ridiculous: it literally has no nourishment – you just chew it to give yourself something to do with your stupid idiot Western mouth. Half the world is starving, and the other’s going, ‘I don’t actually need any nutrition, but it would be good to masticate, just to keep my mind off things.

I've come off heroin twice, and the worst part is laying in bed kicking and not being able to keep still. The physical withdrawal doesn't last that long, but then it's just all psychological. I think it's worse than cigarettes.

No one shuts their laptop after looking at pornography and says, 'What a productive time I just spent connecting with the world!'

Even as a junkie I stayed true [to vegetarianism] - 'I shall have heroin, but I shan't have a hamburger.' What a sexy little paradox.

I think many of the boundaries that convention has placed upon us are arbitrary, so we can fiddle with them if we fancy. Gravity's hard to dispute, and breathing, but a lot of things we instinctively obey are a lot of old tosh.

In England, we have such good manners that if someone says something impolite, the police will get involved.
