The artist’s aim is not to instruct the viewer, but to give information, whether the viewer understands the information is incidental to the artist.

Artists teach critics what to think. Critics repeat what the artists teach them.

A work of art may be understood as a conductor from the artist's mind to the viewer's. But it may never reach the viewer, or it may never leave the artist's mind.

Once it is out of his hand the artist has no control over the way a viewer will perceive the work. Different people will understand the same thing in a different way.

Conceptual art is only good if the idea is good.
