… 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?

Of all the arts, abstract painting is the most difficult. It demands that you know how to draw well, that you have a heightened sensitivity for composition and for colors, and that you be a true poet. This last is essential.

The artist is not a 'Sunday child' for whom everything immediately succeeds. He does not have the right to live without duty. The task that is assigned to him is painful, it is a heavy cross for him to bear.

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.

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.

The eyes are hammers.

Color cannot stand alone.
