Only a radical cleaning of social and artistic life as, in the domain of art, is already done by Dada, which is anti-sentimental and healthy to the c… - Theo van Doesburg

Marinetti's [leading Futurism founder and theorist] Tactilism can be seen as an instinctive effort in this direction [of the new architecture, according to Van Doesburg] even if it presents only the sensuous-tactile expression of space through using various materials. Picasso's earlier compositions in various materials also concerns us here. The Russian artists [ Tatlin and Lissitzky, both Constructivist artists] also appreciated the exterior quality of the plane, not only optical, but also in a tactile manner.. .Intuition already produced a foreknowledge of these new realms, but they can be established fully only by science.

Plastic expression in architecture is inconceivable without colour. Colour and light complete one another. Without colour architecture is expressionless, blind.. .If the Functionalists wish to suppress colour completely, then this merely proves that they never understood the importance of colour as an ‘architectural’ element, as a means of plastic expression, no matter whether used with iron, glass, or concrete.

European art [however] has developed from mimetic-ism and only today is arriving at an elementary plastic art.
