Art is not vague production, transitory and isolated, but a power which must be directed to the improvement and refinement of the human soul.

The artist must have something to say, for mastery over form is not his goal but rather the adapting of form to its inner meaning.

Those [things] that we encounter for the first time immediately have a spiritual effect upon us. A child, for whom every object is new, experiences the world in this way: it sees light, is attracted by it, wants to grasp it, burns its finger in the process, and thus learns fear and respect for the flame.

Every work of art is the child of its age and, in many cases, the mother of our emotions. It follows that each period of culture produces an art of its own which can never be repeated.

The sound of colors is so definite that it would be hard to find anyone who would express bright yellow with bass notes or dark lake with treble.

… lend your ears to music, open your eyes to painting, and … stop thinking! Just ask yourself whether the work has enabled you to “walk about” into a hitherto unknown world. If the answer is yes, what more do you want?

Generally speaking, color directly influences the soul.
