The world doesn't understand me and I don't understand the world, that's why I've withdrawn from it.

The landscape becomes human, becomes a thinking, living being within me. I become one with my picture...we merge in an iridescent chaos.

The landscape thinks itself in me and I am its consciousness.

I am the primitive of the method I have invented.

Art first of all is optical. That's where the material of our art is: in what our eyes think.

Shadow is a colour as light is, but less brilliant; light and shadow are only the relation of two tones.

I could paint for a hundred years, a thousand years without stopping and I would still feel as though I knew nothing.
