Unless a picture shocks, it is nothing.

I feel shame, not for the wrong things I have done, but for the right things that I have failed to do.

I was interested in ideas, not merely visual products. I wanted to put painting once again at the service of the mind.

If a shadow is a two-dimensional projection of the three-dimensional world, then the three-dimensional world as we know it is the projection of the four-dimensional Universe.

I've decided that art is a habit-forming drug. That's all it is, for the artist, for the collector, for anybody connected with it.

As soon as we start putting our thoughts into words and sentences everything gets distorted, language is just no damn good—I use it because I have to, but I don’t put any trust in it. We never understand each other.

What I have in mind is that art may be bad, good or indifferent, but, whatever adjective is used, we must call it art, and bad art is still art in the same way that a bad emotion is still an emotion.
