I think the art fair is very much a form of urbanism. I think something really happens to the cities when such a fair happens. The city becomes an exhibition; it's amazing.

I still remember my first Giacometti exhibition, and going back to the museum every day, whenever I could, to look again and again at these long, thin stick figures, so beautiful, so graceful. That, I think, was the moment I became really obsessed by art.

Making art is not the matter of a moment, and nor is making an exhibition; curating follows art.

Mr. Koons's work has always inspired architects, which I think is very interesting. I think he is an artist who has reinvented himself so many times and reinvented so many different series.

I really do think artists are the most important people on the planet, and if what I do is a utility and helps them, then that makes me happy. I want to be helpful.

At a certain time, an artist needs a big retrospective. At other times, they need a more focused exhibition. It's a different story each time; it's about establishing a dialogue.
