I want the pictures to be working in both directions. I accept that they speak about me, and yet at the same time, I want and expect them to function in terms of the viewer and their experience. With these abstract pictures, although the eye recognizes them as photographic rather than painted, the eye also tries to connect them to reality. There's always this association machine working in the brain, and that is why it is important to me that they are actually photographic and not painted.

The picture of the guy pissing on the chair was a picture I had to do. I had the idea of this absurd act of pissing on a chair rather than in a toilet or on the ground, and this minimal act being so transgressive, even though no major harm is done.

It would be so easy to lose the plot now. It's not about achieving something for its own sake, and taking pictures for their own sake. But to make conscious decisions and choices, and it includes this constant questioning - Why am I taking pictures? Because really, the world is... it has pictures enough. I mean, there are enough pictures out there.

Books have this function that help me to understand the work I've done, to wrap it up. Once it's done, fortunately, it doesn't mean there's closure. Change in my work happens not in revolutions - it's more evolutionary.

Whatever pictures are put into the world, the balance needs to be readdressed, it needs to be observed. That's why I am also really questioning what a lot of photography has done since I began. I am not saying because of me, but I mean, photographing some friends partying and publishing the pictures meant something else in '92 than it does in 2011. And I find the younger generation is not questioning this at all today.

I think there is something very consoling in feeling lost in space but also feeling grounded, and seeing that all of this is part of a bigger clockwork
