What the art historians had forgotten is that in Chinese, Japanese, Persian, and Indian art, they never painted shadows. Why did they paint shadows in European art? Shadows are because of optics. Optics need shadows and strong light. Strong light makes the deepest shadows. It took me a few years to realize fully that the art historians didn't grasp that. There are a lot of interesting new things, ideas, pictures.

There are enough no smoking places now.

Every good artist I know, I always think works hard, we're working all the time.

I'm sure that the camera is part of European art.

The picture itself is a document. How do you mean? We're looking at a document. It gives you clues.

If we are to change our world view, images have to change.

Cubism was an attack on the perspective that had been known and used for 500 years. It was the first big, big change. It confused people: they said, 'Things don't look like that!'
