I am faithful up to the point of death. It's the only thing I respect. I never abandon anyone. I'm not talking about sexual relations. I'm faithful in my friendship, my admiration.

I never abandoned Yves Saint Laurent. I used to have lunch with him twice a week. I also saw him every Saturday. My presence beside him was even more important in his bad times. But that didn't leave me a great deal of room in which to maneuver. Freedom is an intellectual space. But I don't use it.

There's nothing that really motivates me anymore and demands that I get up in the morning. In the past it was Yves Saint Laurent.

I carried on buying paintings, works of art, and Yves Saint Laurent, if I may say so, had a right of inspection. We even shared a common reading of the history of art. It would never have crossed Yves's mind to say to me, "Ah, I saw a Pablo Picasso . . ." He knew perfectly well what was interesting with Picasso, as did I.

I met Andy Warhol in the '60s, a wonderful time, with wonderful people. There was Fred Hughes, and Jed Johnson, who I liked a lot. Jed Johnson decorated my apartment in New York, at the Pierre. It was his first job.

I love Marcel Proust, but I leave him to his nostalgia. I don't approach art the way most people do. I don't get into Proust by imagining that I am Charlus or whoever. It's the same thing in painting - I try to look at it objectively. There's no pathos in that. It's like Bach's "Goldberg Variations." They have to be approached with a scalpel.

I'm not an ascetic and please don't use the word zen, which is so lightly bandied about these days. Being zen . . . It's shameful to talk in such a way. I haven't become an ascetic but I'm not going to build up another collection. I'm going to create my new environment. I already know what I want.
