Theo van Doesburg Quote

I would like to offer an illustration. Imagine a house which is well designed from a material or practical point of view.... Apart from these physio-functional demands, there are also psycho-functional demands which correspond with our optical, phonetic and tactile experiences. Until now, mankind has attempted to satisfy these 'supra-material' demands with a painting on the wall or a sculpture in a room.... the architecture of the future will have to destroy this duality. Its task will be to express completely and fulfill all our demands.

quote from his unpublished writing, in 'Fundamental principles', 1930; as quoted in Theo van Doesburg, Joost Baljeu, Studio Vista, London 1974, p. 203
