If you're going to be a visual artist, then there has to be something in the work that accounts for the possibility of the invisible, the opposite of the visual experience. That's why it's not like a table or a car or something. I think that that might even be hard for people because most of our visual experiences are of tables. It has no business being anything else but a table. But a painting or a sculpture really exists somewhere between itself, what it is, and what it is not-you know, the very thing. And how the artist engineers or manages that is the question.
