Each superfluous line, each wrongly placed line, any color placed without veneration or care, can spoil everything, that is, the spiritual.
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.
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.
