The work of art should be entirely conceived and formed by the mind before its execution. It should receive nothing from Nature’s formal properties o… - Theo van Doesburg

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.

..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)

Elementarism has been born partly in reaction to an over-dogmatic and often narrow-minded application of NeoPlasticism [a critic on his former artist-companion Piet Mondrian, partly as its consequence but ultimately from what is primarily a radical correction of Neo-plastic ideas. Elementarism rejects the demands of pure statics which led to sterility and to the laming of creative potentialities. Instead of denying Time and Space, Elementarism acknowledge these elements to be the most elementary means for creating a new plastic expression.. .In contrast to the Neo-plastic [= De Stijl] manner of expression, which is restricted to two dimensions [the plane], Elementarism acknowledges a form of plastic expression in four dimensions, the realm of space-time. In opposition to the orthogonal style of plastic expression, which is 'homogeneous' with natural construction, Elementarism postulates a 'heterogeneous' contrasting, unstable manner of plastic expression based upon planes oblique in relation to the static, perpendicular axis of gravitation
