"Since one cannot create 'depth' by carving a hole in the picture, and since one should not attempt to create the illusion of depth by tonal gradation, depth as a plastic reality must be two dimensions in a formal sense as well in the sense of color. 'Depth' is not created on a flat surface as an illusion, but as a plastic reality. The nature of the picture plane makes it possible to achieve depth without destroying the two-dimensional essence of the picture plane. .A plane is a fragment in the architecture of space. When a number of planes are opposed one to another, a spatial effect results. A plane functions in the same manner as the walls of a building.. .Planes organized within a picture create the pictorial space of its composition.. .The old masters were plane-consciousness. This makes their pictures restful as well as vital..."

“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.”
