Ludwig Mies van der Rohe formulated these words at the end of a lecture on the Deutscher Werkbund.
He said, influenced by the world economic crisis that began to affect the world in 1929, that the worsening economic and social conditions are a huge challenge for the future architects. The main issue for architects is to produce still valuable objects. It should be not important, how they look like and where they are. To define their style is not important for him.
