True realism, materialist realism lies in the search for the expression of forms faithful to their content. But there is no content detached from human interest.

Everything is in constant flux, from state to state, from good to bad and back again... only in transmutation, perpetual motion, lies truth.

In the beginning was the image.

The act of expressing oneself is a physical one. It materializes the thought.

This is what aesthetics, development and progress depend upon: that we go out on thin ice.

We are sparks that must glow as brightly as possible.

If you add something to a painting, never let it be for aesthetic reasons. Only let it be for reasons of expression.
