[ Futurism's] ..superficial expression of velocity, the aeroplane, the racing-car and so on, is but a weak expression of the inner velocity of though… - Theo van Doesburg

..the modern artist can conclude that impulsive and speculative production has come to an end. THE ERA OF DECORATIVE TASTE HAS VANISHED, the artist of today has finished completely with the past. Scientific and technical developments oblige him to draw conclusions.. ..to revise his means, to establish laws creating a system, that is to say, to master his elementary means of expression in a conscious manner.

'Art' is a Renaissance invention which has been carried to a state of extreme refinement in the present day. This is the so-called 'abstract art'. The production of good works of art was achieved only at the cost of an enormous concentration upon certain matters. This concentration could be achieved only through neglecting 'life', through the very loss of life- just as religion had experienced before. 'Today this situation is no longer tolerable'. Today life is paramount. Modern life in general rejects all tendencies towards isolation and ivory tower-like exclusiveness. It is absolute un-modern to concentrate upon just one thing (as did the middle Ages!) Modern life is based upon the construction, which is to say, upon a system of tensions or the neutralization of the system of carry and support. In agreement with this concept we too must distribute our vitality over the whole range of life taken in the broadest possible sense. All other attitudes towards life produce tragedy.

..art and life are no longer separate domains.. .The word 'art' no longer has anything to say to us. In place of that, we [=De Stijl-artists ] insist upon the construction of our surroundings according to creative laws, deriving from a fixed principle. (quote of 1918)
