Every true artist has been inspired more by the beauty of lines and color and the relationships between them than by the concrete subject of the picture.

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.

The only problem in art is to achieve a balance between the subjective and the objective.

Why should art continue to follow nature when every other field has left nature behind?

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 position of the artist is humble. He is essentially a channel.

Cubism did not accept the logical consequences of its own discoveries; it was not developing abstraction towards its own goal, the expression of pure reality.
