I think you too recognize the important relationship between philosophy and art, and it is just this relationship that most painters deny. The great masters do grasp it, unconsciously; but I believe that a painter's conscious spiritual knowledge will have a much greater influence upon his art, and that it would be due only to a weakness in him, or lack of genius, should this spiritual knowledge be harmful to his art.
Piet MondrianTo approach the spiritual in art, one will make as little use as possible of reality, because reality is opposed to the spiritual.
Piet MondrianEvery 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.
