I think an artist has the potential to investigate both form and content within one activity, to show that there can be coherence between form and values in our society, as in thinking about a city and building one.

There are 1.3 billion people today who have no access to electricity. Many of them rely on kerosene lanterns for light, but kerosene is both expensive and hazardous to the health.

For the sake of sanity, the brain and the eyes keep things simple. But take away the sense of sight and suddenly things are not so simple.

I don't know a single collector or museum director who says: 'Oh, he's on a list, so I think I'll buy something of his.' The people who buy my art put a little more thought into it than that.

Artists are valuable to public discussion: They show the correlation between doing and thinking.

I see the artist as a participant, a co-producer of reality. I do not see the artist as a person who sits at a distance and evaluates.

By bringing Little Sun to Tate Modern and the London Olympics, I hope to realise an art project for those who typically have no access to global events of this scale.
