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.

People from the village come up and tease me: 'We hear you've started drawing on your telephone.' And I tell them, 'Well, no, actually, it's just that occasionally I speak on my sketch pad,'

I think photography has made us see the landscape in a very dull way - that's one of its effects. It's not spatial.

We live in an age where the artist is forgotten. He is a researcher. I see myself that way.

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!'

I think I am seeing more clearly now than ever.

It's time to debate images, especially when someone's going to prison for downloading them.
