An artist must forget painting when he paints. That's the only way he will do original work.

We artists are indestructible; even in a prison, or in a concentration camp, I would be almighty in my own world of art, even if I had to paint my pictures with my wet tongue on the dusty floor of my cell.

The hidden harmony is better than the obvious.

We have a definite but unknown quantity of experience at our disposal. As soon as the hourglass is turned, the sand will begin to run out and once it starts, it cannot stop until it's all gone.

Painting is not made to decorate apartments. It's an offensive and defensive weapon against the enemy. (about Guernica).

I paint the way some people write an autobiography. The paintings, finished or not, are the pages from my diary.

Museums are just a lot of lies, and the people who make art their business are mostly imposters. We have infected the pictures in museums with all our stupidities, all our mistakes, all our poverty of spirit. We have turned them into petty and ridiculous things.
