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

The surface of things gives enjoyment, their interiority gives life.

abstract art is not the creation of another reality but the true vision of reality.

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

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

What 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.

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.
