Marinetti's [leading Futurism founder and theorist] Tactilism can be seen as an instinctive effort in this direction [of the new architecture, acoording 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.
