Dada is able to mobilize the optical and dimensional static viewpoint which keeps us imprisoned in our [three-dimensional] illusions. Thus it became … - Theo van Doesburg

..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.

'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.

Piet Mondrian realizes the importance of line. The line has almost become a work of art in itself; one can not play with it when the representation of objects perceived was all-important. The white canvas is almost solemn. Each superfluous line, each wrongly placed line, any color placed without veneration or care, can spoil everything – that is, the spiritual.
