The art of pictorial creation is so complicated — it is so astronomical in its possibilities of relation and combination that it would take an act of… - Hans Hofmann

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...

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.

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.
