Everything rhythmically organic is true. Everything, which results from the proper feeling for rhythmically organized spiritual units, is true and alive — alive within itself. When we lose the sense for such true beauty we lose our natural sense for the rich flavor of life, which is the basis for all inspirational work. Things generally taken for beautiful are nothing other than the product of frozen, stereotyped taste, bound by sterile rules and purely exterior judgment.

The general misunderstanding of a work of art is often due to the fact that the key to its spiritual content and technical means is missed. Unless the observer is trained to a certain degree in the artistic idiom, he is apt to search for things which have little to do with the aesthetic content of a picture. He is likely to look for pure representational values when the emphasis is really upon music-like relationships.

It takes intelligence and training, self-discipline and fine-sensibility, to gain renewed life through leisure occupation. America now suffers spiritual poverty, and art must become more fully American life before her leisure can become culture.

Art leads to a more profound concept of life, because art itself is a profound expression of feeling. The artist is born, and art is the expression of his overflowing soul. Because his soul is rich, he cares comparatively little about the superficial necessities of the material world; he sublimates the pressure of material affairs in an artistic experience.

The creative process lies not in imitating, but in paralleling nature — translating the impulse received from nature into the medium of expression, thus vitalizing this medium. The picture should be alive, the statue should be alive, and every work of art should be alive.

The physical carrier is overshadowed by a relation. The relation creates an overtone. The physical carrier is absorbed by this overtone. The overtone spontaneously transforms the means of creation into a spiritual reality. The mystery of creation is then revealed.

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.

One must realize that, apart from considerations of color and form, there are two fundamentally different ways of regarding a medium of expression: one is based on taste only — an approach in which the external physical elements of expression are merely pleasingly arranged. This way results in decoration with no spiritual reaction. Arrangement is not art. The second way is based on the artist’s power of empathy, to feel the intrinsic qualities of the medium of expression. Through these qualities the medium comes to life.. .In this life, an intuitive artist discovers the emotive and vital substance which makes a work of art.

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.

Just as counterpoint and harmony follow their own laws, and differ in rhythm and movement, both formal tensions and color tensions have a development of their own in accordance with the inherent laws from which they are separately derived. Both, however, aim toward the realization of the same image. And both deal with the depth problem.

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.

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...

Depth, in a pictorial, plastic sense, is not created by the arrangement of objects one after another toward a vanishing point, in the sense of the Renaissance perspective, but on the contrary (and in absolute denial of this doctrine) by the creation of forces in the sense of push and pull. Nor is depth created by tonal gradation (another doctrine of the academician which, at its culmination, degraded the use of color to a mere function of expressing dark and light).
