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 MondrianWhat is natural does not have to be a representation of something. I'm now working on a thing that is a reconstruction of a starry sky, and yet I'm making it without a given from nature. Someone who says he uses a theme from nature can be right, but also someone who says he uses nothing at all.
Piet Mondrian
