"Neo-Plasticism has its roots in Cubism. It could just as easy be called the Painting of Real Abstraction. Since the abstract can be expressed by a plastic reality.. .It achieves what all painting has tried to achieve but has been able to express only in a veiled manner. By their position and their dimension as well as by the importance of given to colour, the coloured planes express in a plastic way only relations and not forms. Neo-Plasticism imparts to these relations an aesthetic balance and thereby expresses universal harmony.. .For the moment what art had discovered must still be limited to art itself. Our environment cannot yet be realized as a creation of pure harmony. Art today is at the very point formerly occupied by religion. In its deepest meaning art was the transposition of the natural ; in practice it always sought to achieve harmony between man and untransposed nature. Generally speaking, so do Theosophy and Anthroposophy, although these already possessed the original symbol of balance. And this is why they never were able to achieve equivalent relations, that is to say true harmony."

“To show that this end is only a beginning, it is essential that.. ..the series of galleries be followed by a room in which painting and sculpture will be realized by the interior itself.. ..demonstrating that what is lost for art is gained for life. This room could therefore be designed for use as a lecture room, a restaurant.. ..as a bar with an American jazz band.”

“However, new plasticism is pure painting : the means of expression still are form and color, though these are completely interiorized; the straight line and flat color remain purely pictorial means of expression.”

“It was during this early period of experiment that I first went to Paris. The time was around 1910 when Cubism was in its beginnings. I admired Matisse, Van Dongen and the other Fauves, but I was immediately drawn to the Cubists, especially to Picasso and Léger. Of all the abstractionists I felt that only the Cubists had discovered the right path; and, for a time, I was much influenced by them.”

“Culture produces relative consciousness of the changeable expression of reality. When this consciousness is attained, a revolt takes place: the beginning of the deliverance from that expression of reality. Destruction of its limitation follows. The culture of the intuitive faculties has conquered. A clearer perception of constant reality is possible. A new realism appears.”

“..the elements of form have a particular aspect; every fragment, every plane, every line has its proper character.”
