"A line cannot control pictorial space absolutely. A line may flow freely in and out space, but cannot independently create the phenomenon of push and pull necessary to plastic creation. Push and pull are expanding and contracting forces which are activated by carriers in visual motion. Planes are the most important carriers, lines and points less so.. .the picture plane reacts automatically in the opposite direction to the stimulus received; thus action continues as long as it receives stimulus in the creative process. Push answers with pull and pull with push. ... At the end of his life and the height of his capacity Cézanne understood color as a force of push and pull. In his pictures he created an enormous sense of volume, breathing, pulsating, expanding, contracting through his use of colors."

“The impressionistic method leads into a complete splitting and dissolution of all areas involved in the composition, and color is used to create an overall effect of light. The color is, through such a shading down from the highest light in the deepest shadows, sacrified an degraded to a function. This leads to the destructions of the color as color.”

“Then I was still under nature, not that I was imitating it; now I am above nature. But everything comes from nature, I too am part of nature; my memory comes from nature, too.”

“A thought that has found a plastic expression must continue to expand in keeping with its own plastic idiom. A plastic idea must be expressed with plastic means just as a musical idea is expressed with musical means, or a literary idea with verbal means. Neither music nor literature are wholly translatable into other art forms; and so a plastic art cannot be created through a superimposed literary meaning. The artist who attempts to do so produces nothing more than a show-booth. He contents himself with visual story-telling. He subjects himself to a mechanistic kind of thinking which disintegrates into fragments.”

“The reciprocal relation of color to color produces a phenomenon of a more mysterious order. This new phenomenon is psychological. A high sensitivity is necessary in order to expand color into the sphere of the surreal without losing creative ground. Color stimulates certain moods in us. It awakens joy or fear in accordance with its figuration. In fact, the whole world, as we experience it visually, comes to us through the mystic realm of color. Our entire being is nourished by it. This mystic quality of color should likewise find expression in a work of art.”

“It is the greatest injustice done to Mondrian that people who are plastically blind see only decorative design instead of the plastic perfection which characterizes his work. The whole De Stijl group from which Mondrian's art was derived must be considered a protest against such blindness.”
