Exhibitions usually are not collected; they disperse after they take place.

I'm trying to expand the notion of curating. Exhibitions need not only take place in galleries, need not only involve displaying objects. Art can appear where we expect it least.

One of my favourite exhibitions is called 'Do It,' which I co-curated with the artists Christian Boltanski and Bertrand Lavier 21 years ago.

Exhibitions are kind of ephemeral moments, sometimes magic moments, and when they're gone, they're gone.

I started going to exhibitions in Switzerland when I was 10 or 11. As a schoolboy, I would go every afternoon to see the long, thin figures of Giacometti.

For me, the making of exhibitions has always had to do with dialogue: a concentrated, in-depth, focused dialogue with artists, who keep teaching me that exhibitions should always invent new rules for the game.
