"The evening is indescribable. And on the top of everything else a full moon came up. Louis urged me to paint it. I said: it will be an exercise at best. Naturally I am not up to this kind of nature. Still, I know a bit more than I did before. I know the disparity between my inadequate resources and nature. This is an internal affair to keep me busy for the next few years. It doesn't trouble me one bit. No use hurrying when you want so much. The evening is deep inside me forever. Many a blond, northern moon rise, like a muted reflection, will softly remind me, and remind me again and again. It will be my bride, my alter ego. An incentive to find myself. I myself am the moon-rise of the South."

“Graphic work as the expressive movement of the hand holding the recording pencil.. ..is so fundamentally different from dealing with tone and color that one can use this technique quite well in the dark, even in the blackest night. On the other hand, tone presupposes some light, and color presupposes a great deal of light.”

“My etchings have.. ..the mistake of being processed as images and to have at the same time the meaning of epigrams. It is the union of pure painting with pure graphics.. .From now onwards my task will be the division of art and graphics, and the full development of both fields. The pure art has already turned to impressionism and the graphics is going to do it.”

“..I thought I had come into the clear in art when for the first time I was able to apply an abstract style to nature.”

“It is interesting to observe how real the object remains, in spite of all abstractions.”

“His pathos is alien to me, especially in my current phase, but he is certainly a genius. Pathetic to the point of being pathological, this endangered man can endanger one who does not see through him. Here a brain is consumed by the fire of a star. It frees itself in its work just before the catastrophe. Deepest tragedy takes place here, real tragedy, natural tragedy, exemplary tragedy. Permit me to be terrified.”
