It is the same with art. Art will become the product of another duality in man: the product of a cultivated externality and of an inwardness deepened… - Piet Mondrian

Art is higher than reality and has no direct relation to reality. To approach the spiritual in art, one will make as little use as possible of reality, because reality is opposed to the spiritual. We find ourselves in the presence of an abstract art. Art should be above reality, otherwise it would have no value for man.

Only now I become conscious that my work in black, white and little color planes has been merely 'drawing' in oil color. In drawing, the lines are the principal means of expressions.. .In painting, however, the lines are absorbed by the color planes; but the limitations of the planes show themselves as lines and conserve their great value.

Though I do, of course agree with the principles you have mentioned, I am returning the paper unsigned, as I do not want to belong to a group. A group of people with one aim is not as yet a single-minded group and as this does not exist, a consistent group remains impossible. And a larger group only makes sense for joint exhibitions and for spreading ideas. I will therefore not participate in the other group either, but I have promised my collaboration in this respect. If you definitely want to form a group, you can always invite myself and others who are proved to be suitable. Only on such a basis I will collaborate with the other group as well.
