True artistic experience is never passive, for the spectator is obliged to participate, as it were, in the continuous or discontinuous variations of … - Theo van Doesburg

After having passed through the various phases of plastic creation [the phases of arrangement, composition, and construction] I have arrived at the creation of 'universal forms' through constructing upon an arithmetical basis with the pure elements of painting.

The artist's studio will be like a glass-bell or a hollow crystal. The painter himself must be white, which is to say, without tragedy or sorrow. The pallet must be of glass; the brush must be square and hard, dust-free and as immaculate as a surgical instrument. Doubtless there is much to learn from a medical laboratory.. .The studio of the modern painter must reflect the ambiance of mountains which are nine thousand feet high and topped with a eternal cap of snow. There the cold kills the microbes.

The complete and definitive work of art is created beyond one's individuality.. .The universal transcends such a level. Mere spontaneity has never created a work of art which possesses a lasting cultural value. The method leading to universal form is based upon calculations of measure and number.
