The reason why the stone is red is its iron content, which is also why our blood is red.

The relationship between the public and the artist is complex and difficult to explain. There is a fine line between using this critical energy creatively and pandering to it.

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.

I can't edit the materials I work with. My remit is to work with nature as a whole.

The underlying tension of a lot of my art is to try and look through the surface appearance of things. Inevitably, one way of getting beneath the surface is to introduce a hole, a window into what lies below.

I'm very fortunate to be able to do what I do and live the way I do.

We often forget that we are nature.
