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 the hand that, by touching this or that key, sets the soul vibrating automatically.

The nightmare of materialism, which has turned the life of the universe into an evil, useless game, is not yet past; it holds the awakening soul still in its grip.

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

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 artist must be blind to distinction between 'recognized' or 'unrecognized' conventions of form, deaf to the transitory teaching and demands of his particular age.

There is only one road to follow, that of analysis of the basic elements in order to arrive ultimately at an adequate graphic expression.
