Usually I am on a work for a long stretch, until a moment arrives when the air of the arbitrary vanishes, and the paint falls into positions that feel destined.
I don't know what a painting is; who knows what sets off even the desire to paint? It might be things, thoughts, a memory, sensations, which have nothing to do directly with painting itself. They can come from anything and anywhere.
The painting is not on a surface, but on a plane which is imagined. It moves in a mind. It is not there physically at all. It is an illusion, a piece of magic, so that what you see is not what you see.
Painting and sculpture are very archaic forms. It's the only thing left in our industrial society where an individual alone can make something with not just his own hands, but brains, imagination, heart maybe.
In my experience a painting is not made with colors and paint at all. I don't know what a painting is; who knows what sets off even the desire to paint?
