Poetry is the essence of everything, and it’s through deep contact with reality and living fully that you reach poetry. Very often I see photographers cultivating the strangeness or awkwardness of a scene, thinking it is poetry. No. Poetry is two elements which are suddenly conflict — a spark between two elements. But it’s given very seldom, and you can’t look for it. It’s like if you look for inspiration. No, it just comes by enriching yourself and living.

Looking, touching, material, place and form are all inseparable from the resulting work. It is difficult to say where one stops and another begins. The energy and space around a material are as important as the energy and space within. The weather--rain, sun, snow, hail, mist, calm--is that external space made visible. When I touch a rock, I am touching and working the space around it. It is not independent of its surroundings, and the way it sits tells how it came to be there.

Recently I have been working in the country, where, carving in the open air, I find sculpture more natural than in a London studio, but it needs bigger dimensions. A large piece of stone or wood placed almost anywhere at random in a field, orchard, or garden, immediately looks right and inspiring.

Street art, of course, is political, because it's illegal, so the very act of doing it is an act of defiance.

I love New York. You can pop out of the Underworld in Central Park, hail a taxi, head down Fifth Avenue with a giant hellhound loping behind you, and nobody even looks at you funny.

I went to the zoo one day and saw a chimp playing with a beat-up acoustic guitar in a way I had never seen before. Instead of using the pick the chimp was banging the neck and tapping it with its fingers. I knew the chimp was on to something so I practiced this new technique in my room for hours until I'd perfected it.
