We speak of concrete and not abstract painting because nothing is more concrete, more real than a line, a color, a surface.
Theo van DoesburgOur time has produced a need for contrast. This has been achieved not only in the external appearance of plastic expressions of coulor and matter, but also, and chiefly, in the tempo of life and in the techniques related to the daily, mechanical functions of life; namely standing, walking, driving, to lying and sitting - in short, every action which determines the content of architecture.
Theo van DoesburgTo be oneself is being neither under bond nor borrowed nor sold nor hired. To be, means to be spiritually free.
Theo van DoesburgEach superfluous line, each wrongly placed line, any color placed without veneration or care, can spoil everything, that is, the spiritual.
Theo van DoesburgIn all these products, whether iron bridges, locomotives, automobiles, telescopes, cottages, airport-hangars, funicular railways, skyscrapers, or children's toys, the will towards a new style expresses itself. The similarity of these examples to the new creations in art consists in the same striving for clear, pure form which expresses truth in the objects.
