There is an old and a new consciousness of the age. The old one is directed towards the individual. The new one is directed towards the universal. The struggle of the individual against the universal may be seen both in the world war and in modern art.
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 DoesburgWe speak of concrete and not abstract painting because nothing is more concrete, more real than a line, a color, a surface.
