I am not a 'book of the month' artist, and I do not paint pretty pictures; but when I am no longer here my name will register forever in the history … - Marsden Hartley

..of what use is a painting which does not realize its aesthetical problem? Underlying all sensible works of art, there must be somewhere in evidence the particular problems understood. It was so with those artists of the great past who had the intellectual knowledge of structure upon which to place their emotions. It is this structural beauty that makes the old [clssical] painting valuable. And so it becomes to me a problem. I would rather be sure that I had placed two colors in true relationship to each other than to have exposed a wealth of emotionalism gone wrong in the name of richness of personal expression.. .The real artists have always been interested in this problem, and you feel it strongly in the work of [Leonardo] Da Vinci, Piero della Francesca, Courbet, Pissarro, Seurat, and Cezanne.

Cubism taught me much and the principle of Pissarro, furthered by Seurat, taught me more. These with Cezanne are the great logicians of color.
No one will ever paint like Cezanne for example, because no one will ever have his peculiar visual gifts; or to put it less dogmatically, will anyone ever appear again with so peculiar and almost unbelievable a faculty for dividing color sensations and making logical realizations of them? Has anyone ever placed his color more reasonably with more of a sense of time and measure than he? I think not, and he furnished for the enthusiast of today new reasons for research into the realm of color for itself.

I have made the complete return [from imagination] to nature, and nature is, as we all know, primarily an intellectual idea. I am satisfied that painting also is like nature, an intellectual idea, and that the laws of nature as presented to the mind through the eye and the eye is the painter's first and last vehicle are the means of transport to the real mode of thought: the only legitimate source of aesthetic experience for the intelligent painter.
