In 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.
Theo van DoesburgWhen contemplating a work of art it is possible to perceive if it has been created according to the eye or to the spirit, in other words, if it projects three-dimensional reality or spiritual n-dimensionality.
Theo van DoesburgWe 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.
