Plastic expression in architecture is inconceivable without colour. Colour and light complete one another. Without colour architecture is expressionl… - Theo van Doesburg

It must be emphasized that in seeing a work of art that has been composed by precise means, the viewer does not perceive dominant details. His impression is one of perfect balance to which all the parts contribute, an impression which not only applies to the parts as such, but is transmitted also to the relation existing between the work of art and the viewer. Although it is very difficult to express in words the effect of a work of art, it may be said that the viewer’s deepest impression can best be defined as the achievement of a balance between objective meaning and subjective meaning, both directly penetrated by awareness. He has a sensation of height and of depth which are no longer in any way bound to natural conditions or to spatial dimensions, a sensation which places the viewer in a state of consciousness harmony.

The development of plastic art is determined by the will to visualize. Art of the past represented the subjective vision of 'naturalistic relationships'. Neoplasticism embodies a subjective vision of 'plastic' relationships.. .Pure thought, which does not signify a concept derived from natural phenomena but which is contained in numbers, measures, relationships and abstract lines, is revealed conceptually (as Reason) by Chinese, Greek and German philosophy, and aesthetically by contemporary Neoplasticism [= De Stijl.

'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.
