"Not all Constructivists concentrate so strongly on reality. There are those for whom inner life plays an important part, such as the non-Russian Moholy Nagy, Kassak, and Baumeister etc. Their art painting figures often have a more symbolic meaning.. .Sometimes without any direct connection to reality.. .Moholy Nagy’s work is 'l’art pour l’art' - as opposed to El Lissitsky who is demonstrative.. ..in as much as he propagates the Bolshevist morale of not dreaming but doing."
