Marc Chagall

When I am finishing a picture, I hold some God-made object up to it - a rock, a flower, the branch of a tree or my hand - as a final test. If the painting stands up beside a thing man cannot make, the painting is authentic. If there's a clash between the two, it's bad art.

We exist in this weirdly schizo culture, where sex is everywhere in the media, and yet, at the same time, you don't sit down and have a conversation about what you did in bed last night with your friends. Despite the ubiquity of sex, it's still a taboo when it comes to day-to-day conversation.
