I like nature but not its substitutes. Naturalist art, illusionism, is a substitute for nature. I remember that in arguing with Piet Mondrian [in Paris, 1920's], he opposed art to nature saying that art is artificial and nature is natural. I do not share this opinion. I do not think that nature is in natural opposition to art. Art's origins are natural.

A deep and serene silence filled her structures composed of colors and surfaces. The exclusive use of horizontal and vertical rectangular planes in the work of art, the extreme simplification, exerted a decisive influence on my work. Here I found, stripped down to the limit, the essential elements of all earthly constructions: the bursting, upward surge of the lines and the planes toward the sky, the verticality of pure life, and the vast equilibrium, the sheer horizontality and expansiveness of dreamlike peace. Her work was for me a symbol of a divinely built 'house' which man in his vanity has ravaged and sullied.

art is fruit growing out of man like the fruit out of a plant like the child out of the mother. While the fruit of the plant grows independent forms and never resembles a balloon or a president in a cutaway suit the artistic fruit of man shows for the most part a ridiculous resemblance to the appearance of other things. Reason tells man to stand above nature and to be the measure of all things. thus man thinks he is able to live and to create against the laws of nature and he creates abortions. through reason man became a tragic and ugly figure. i dare say he would create even his children in the form of vases with umbilical cords if he could do so. reason has cut man off from nature.
