Colored planes, by their position and size as well as by their value, express only relationships, not forms.

If you follow nature you will not be able to vanquish the tragic in any real degree in your art... We must free ourselves from our attachment to the external, for only then do we transcend the tragic, and are enabled consciously to contemplate the repose which is within all things.

The relation of color and the relation of proportion are both based on the relation of position.

The colored planes, as much by position and dimension as by the greater value given to color, plastically express only relationships and not forms.

The essence of painting has actually always been to make it [the universal] plastically perceptible through colour and line.

Vertical and horizontal lines are the expression of two opposing forces; they exist everywhere and dominate everything; their reciprocal action constitutes 'life'. I recognized that the equilibrium of any particular aspect of nature rests on the equivalence of its opposites.
