It's no longer terribly sexy to own shares in certain companies; it used to be that being a shareholder in a corporation would connect you with it. The result is that people really want to invest in valuable things, and contemporary art has become a very stable material value with great growth potential.

I am myself a professional creator of images, a film-maker. And then there are the images made by the artists I collect, and I have noticed that the images I create are not so very different from theirs. Such images seem to suggest how I feel about being here, on this planet. And maybe that is why it is so exciting to live with images created by other people, images that either conflict with one's own or demonstrate similarities to them.

I am intrigued by the basics of human life, by our vulnerability, our desires, our sexuality - as far as I am concerned, character is expressed through sexuality. Art is able to represent human existence stripped to its essence by showing us the naked human body.

If you're smart enough you realise that your possessions possess you in their turn. Collecting has a neurotic aspect. I find it boring when collectors found their own private museums or try to establish a memorial to themselves in the form of their collections, it's part of the old aristocratic mentality. I think a collection ought to be dismantled after the collector's death.

Secrets can actually be quite important. A work of art that reveals its meaning or its power too quickly is uninteresting. It might not even be a good work of art.

Sex is probably one of the last forms of human expression to enjoy such a direct connection with nature. It might be the primary site of conflict between nature and culture. If one assumes that nature (or instinct) is repressed in a highly civilised society, then I think the conceptual dyad nature-culture is best preserved there, in the realm of sex.

The art market does represent a sort of hyper-capitalism: it produces added value without any actual work being done.
