‘Is it possible to make a work of art that is not embodied in an object?’

A ponderous silence.

‘Well?’ said Delia.

‘Is it the artist’s job to answer questions, or to ask them?’

In a classroom in Manhattan on a rainy day, my perception of art was changed forever. Vito Acconci’s pedagogy was a mixture of persistent enquiry, faith in the invisible and nudges toward the unknown. It struck me for the first time that art might exist beyond the realms of painting and sculpture. This was a mind-boggling revelation, like opening a door in your own house and discovering an entirely new room. My jaw went lax, my breathing deepened. The spirit of conceptualism had entered me, and I became a convert then and there.
