Great art picks up where nature ends.

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.

What a genius, that Picasso. It is a pity he doesn't paint.

Art is foremost a state of mind, and only secondarily a problem of form.

The dignity of the artist lies in his duty of keeping awake the sense of wonder in the world. In this long vigil he often has to vary his methods of stimulation; but in this long vigil he is also himself striving against a continual tendency to sleep.

All our interior world is reality, and that, perhaps, more so than our apparent world.
