..modern destruction begins where architectural structure is opened up and set into motion by colour relationships. The colour-planes, however, are always in orthogonal relationship.

..a demand which will never be fulfilled as long as artists use individualistic means. 'Unity can only result from disciplining the means, for it is this discipline which produces more generalized means'. The objectification of the means will lead towards elementary, monumental plastic expression. It would be ridiculous to maintain that none of this relates to creative activity. If that were true, art would not be subject to logical discipline.

The problem which Mondrian undertook to solve in nr. 116 was handled very successfully. This work spiritually dominates all others. It gives the impression of Repose; the repose of the soul. Its predetermined structure embodies 'becoming' rather than 'being'. This represents a true element in art, for art is not 'being', but 'becoming'. The idea of 'becoming' has been expressed in black and white.. ..Through years of hard work my own experiences have led me, before I came to know the theories of Uexkuell or Picasso, to prefer the use of the white-black-grey palette in works of a purely spiritual content...

It is exactly the contrary; true artistic experience is altogether real and conscious

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 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.
