Through art we express our conception of what nature is not.

There's nothing more difficult than a line.

You cannot go against nature. She is stronger than the strongest of men. We can permit ourselves some liberties, but in details only.

Those who attempts to explain a picture are on the wrong track most of the time.

To arrive at abstraction, it is always necessary to begin with a concrete reality.

It is the object which aroused the artist, stimulated his ideas and set of his emotions. These ideas and emotions will be imprisoned in his work for good.

When art critics get together they talk about Form and Structure and Meaning. When artists get together they talk about where you can buy cheap turpentine.
